    The Venezuelan and Colombian basins are located on the Caribbean Plate whilst the Yucatan basin is on the North American Plate. The processes occurring at the boundaries between the Caribbean Plate and the adjacent North American, South American and Cocos Plates, and the resulting surface features and patterns of volcanic and earthquake activity are described. Most of the Caribbean area is floored by atypical oceanic crust and its most valuable main geologic resources identified so far are petroleum, together with sand and gravel. Geological research is being carried out with techniques for broad-range swath imaging of the seafloor, such as GLORIA, and for directly measuring the movement between plates. -J.G.Harvey

    2006-12-01

    The December 2004 Indian Ocean tsunami increased global awareness to the destruction hazard posed by earthquakes and tsunamis around the world. The United States government has committed 37.5 million dollars toward the upgrade of earthquake and tsunami monitoring systems in the Caribbean region. Several historical earthquakes have caused considerable damage throughout the Caribbean, many causing tsunamis. The US Geological Survey is using a large part of this money to enhance capabilities for rapid detection and notification of earthquakes in the Caribbean in an attempt to warn the millions living in this area of possible tsunamis. The USGS is working with the Puerto Rico Seismic Network, the Seismological Research Unit at the University of West Indies, eight other host countries, and the National Oceanic and Atmospheric Administration (NOAA). These groups are in the process of installing or upgrading seismic monitoring sites in the earthquake zones of the region. NOAA is also installing four Deep-ocean Assessment and Reporting of Tsunami (DART) buoys in support of a Caribbean-wide tsunami warning system. Planned seismic stations are located in Antigua/Barbuda, Barbados, Cuba (U.S. Naval Base at Guantanamo Bay), the Dominican Republic, Jamaica, Honduras, Panama, Turks and Caicos, and Grenada. Satellite telemetry will transmit data from these sites to NEIC, Golden, CO, where the data will be redistributed to NOAA, the University of Puerto Rico and the University of the West Indies, the IRIS Data Management Center and other agencies. The development of seismic monitoring operations began on January 9, 2006. This will improve seismic monitoring capabilities in the Caribbean and Central America, provide better real time data for global monitoring research and assessment activities, and improve understanding of historical tsunamis and their effects on the Caribbean.

  6. Caribbean plate interactions

    SciTech Connect

    Ball, M. )

    1993-02-01

    Vector analysis of plate motions, derived from studies of Atlantic magnetic lineations and fracture zone trends, indicates the following relative movements between the Caribbean, North American, and South American Plates. (1) During Early Jurassic to Early Cretaceous, the North American Plate moved 1900 km westward and 900 km northward relative to the South American Plate. A broad zone including the Caribbean region, i.e., the zone between the North and South America Plates, was a site of left-lateral shear and north-south extension. (2) During Early Cretaceous to Late Cretaceous, the North American Mate moved an additional 1200 km westward relative to South America across this zone. (3) During Late Cretaceous to the end of the Eocene, the North American Plate moved 200 km westward and 400 km northward relative to the South American Plate. (4) From the end of the Eocene to near the end of the Miocene, North America converged on South America some 200 km and moved 100 km eastward relative to it. Through the Mesozoic and earliest Tertiary history of the Caribbean, the region was a shear zone within which left-lateral displacement exceeded 3000 km and north-south extension exceeded 1300 km. In regard to time, 80% of the history of the Caribbean region is one of north-south extension and left-lateral shear. In terms of space, 97% of the shear is left-lateral and the ratio of divergence versus convergence is 7 to 1. Thus, characterizing the Caribbean region, and the Atlantic to its east, as a zone of north-south extension and left-lateral shear, is a fair generalization.

    2012-12-01

    Over the past 500 years almost 100 tsunamis have been observed in the Caribbean and Western Atlantic, with at least 3510 people having lost their lives to this hazard since 1842. Furthermore, with the dramatic increase in population and infrastructure along the Caribbean coasts, today, millions of coastal residents, workers and visitors are vulnerable to tsunamis. The UNESCO IOC Intergovernmental Coordination Group for Tsunamis and other Coastal Hazards for the Caribbean and Adjacent Regions (CARIBE EWS) was established in 2005 to coordinate and advance the regional tsunami warning system. The CARIBE EWS focuses on four areas/working groups: (1) Monitoring and Warning, (2) Hazard and Risk Assessment, (3) Communication and (4) Education, Preparedness and Readiness. The sea level monitoring component is under Working Group 1. Although in the current system, it's the seismic data and information that generate the initial tsunami bulletins, it is the data from deep ocean buoys (DARTS) and the coastal sea level gauges that are critical for the actual detection and forecasting of tsunamis impact. Despite multiple efforts and investments in the installation of sea level stations in the region, in 2004 there were only a handful of sea level stations operational in the region (Puerto Rico, US Virgin Islands, Bermuda, Bahamas). Over the past 5 years there has been a steady increase in the number of stations operating in the Caribbean region. As of mid 2012 there were 7 DARTS and 37 coastal gauges with additional ones being installed or funded. In order to reach the goal of 100 operational coastal sea level stations in the Caribbean, the CARIBE EWS recognizes also the importance of maintaining the current stations. For this, a trained workforce in the region for the installation, operation and data analysis and quality control is considered to be critical. Since 2008, three training courses have been offered to the sea level station operators and data analysts. Other

    NASA Astrophysics Data System (ADS)

    Haque-Copilah, Shirin; Cornwall, Derick; Pasha, Syed

    This paper presents the results of a survey conducted in high schools (ages 11-18) among teachers and students to establish the status of Astronomy education in the Caribbean. The survey indicates strong interest in Astronomy among students and educators alike but because of inadequate resources and a lack of teacher training it has not been given the attention it deserves. In addition we present the results of the Caribbean Institute of Astronomy's (CARINA) ongoing efforts at astronomy education and popularization both independently and in conjunction with the only Science Center in the Caribbean. Problems specific to astronomy education in the Caribbean are also discussed with regard to funding communication and lack of human resources.

  11. Tides of the Caribbean Sea

    SciTech Connect

    Kjerfve, B.

    1981-05-20

    Analysis of tidal characteristics from 45 gauge locations indicates that the Caribbean Sea has a microtidal range, for the most part between 10 and 20 cm. The tide is primarily either mixed semidiurnal or mixed diurnal but a substantial section from Puerto Rico to Venezuela experiences diurnal tides. Empirical charts of six component tides (M/sub 2/, S/sub 2/, N/sub 2/, K/sub 1/, O/sub 1/, and P/sub 1/) show local detail of phase and amplitude. Each of the semidiurnal component tides is characterized by anticlockwise rotating amphidromes centered in the eastern Caribbean. There is evidence of strong radiational forcing of the S/sub 2/ tide in the south-western Caribbean. The diurnal component tides are largely uniform in both phase and amplitude for most of the western and central Caribbean. However, the diurnal phases increase rapidly towards the northwest and the Yucatan Channel.

  12. Caribbean paleomagnetism and tectonic evolution

    SciTech Connect

    MacDonald, W.D.

    1985-01-01

    Approximately fifty papers treating diverse aspects of Caribbean paleomagnetism have appeared since Creer's pioneering work in the early 1960s. Apparently anomalous early results were initially attributed to anomalous geomagnetic field behavior, to unusual mineralogic effects in rock magnetism and to complex remagnetizations. Eventually the importance of structural and tectonic influences were recognized in paleomagnetic data of the Caribbean area, as elsewhere. Large tectonic rotation is evident from the unusual paleomagnetic declination found at many Caribbean localities. Latitudinal transport, with its plate motion implications, is more subtly expressed in the paleomagnetic inclination parameter, with its typically large relative variance. A review of Caribbean paleomagnetic data is given to form a basis for composing realistic tectonic models.

  13. The Caribbean after-shock.

    PubMed

    Canak, W L; Levy, D

    1988-03-01

    The population of the Caribbean islands, is expected to double by the mid-21st century, placing new pressures on local labor markets and economic resources and increasing the need for social expenditures. Most of this growth will take place in urban areas. Emigration to the US is an increasingly important trend, especially in the Dominican Republic, Haiti, and Jamaica, and local Caribbean economies are linked with labor markets in the US through a system of family remittances. Oil price hikes, escalating debt burdens, and falling export prices have created an economic crisis in the Caribbean since the late 1970s. There has been double-digit inflation, rising unemployment, and only sporadic growth in the gross national product. The Caribbean Basin Initiative, established by the Reagan Administration, provides the Caribbean nations with duty-free export entry to the US market for 12 years and targets manufacturing, tourism, agriculture, and foreign investment for growth. Overall, however, the results of this initiative have been an effective subsidy to US investors and little stimulus for growth in locally owned businesses. Haiti and the Dominican Republic are the islands with the most poverty, while Trinidad and Tobago are the most prosperous. Puerto Rico plays an important role in the Caribbean region, serving as a link between North and South America and between cultural differences. PMID:12280949

    The Caribbean is a multi-ethnic region with many different cultural differences. The majority of the population is of African descent, but there are also other ethnic groups present such as Indians, Chinese, Syrians and Europeans. The Caribbean region is influenced by countries such as the USA, Great Britain, France and Holland. The countries of the Caribbean have a serious problem with HIV infection and AIDS. The epidemiology of HIV infection in this region, is different from most other parts of the world in that the mode of spread does not easily fit into any of the three WHO patterns. This review shows that the infection initially started in the homosexual/bisexual community, but since then, it has moved to the heterosexual population and this form of contact is now the main mode of transmission of the virus. The Governments of the Caribbean countries have realized the extent of the problem and have taken measures to try to control the epidemic. PMID:8031923

  18. Symbiodinium Photosynthesis in Caribbean Octocorals

    PubMed Central

    Ramsby, Blake D.; Shirur, Kartick P.

    2014-01-01

    Symbioses with the dinoflagellate Symbiodinium form the foundation of tropical coral reef communities. Symbiodinium photosynthesis fuels the growth of an array of marine invertebrates, including cnidarians such as scleractinian corals and octocorals (e.g., gorgonian and soft corals). Studies examining the symbioses between Caribbean gorgonian corals and Symbiodinium are sparse, even though gorgonian corals blanket the landscape of Caribbean coral reefs. The objective of this study was to compare photosynthetic characteristics of Symbiodinium in four common Caribbean gorgonian species: Pterogorgia anceps, Eunicea tourneforti, Pseudoplexaura porosa, and Pseudoplexaura wagenaari. Symbiodinium associated with these four species exhibited differences in Symbiodinium density, chlorophyll a per cell, light absorption by chlorophyll a, and rates of photosynthetic oxygen production. The two Pseudoplexaura species had higher Symbiodinium densities and chlorophyll a per Symbiodinium cell but lower chlorophyll a specific absorption compared to P. anceps and E. tourneforti. Consequently, P. porosa and P. wagenaari had the highest average photosynthetic rates per cm2 but the lowest average photosynthetic rates per Symbiodinium cell or chlorophyll a. With the exception of Symbiodinium from E. tourneforti, isolated Symbiodinium did not photosynthesize at the same rate as Symbiodinium in hospite. Differences in Symbiodinium photosynthetic performance could not be attributed to Symbiodinium type. All P. anceps (n = 9) and P. wagenaari (n = 6) colonies, in addition to one E. tourneforti and three P. porosa colonies, associated with Symbiodinium type B1. The B1 Symbiodinium from these four gorgonian species did not cluster with lineages of B1 Symbiodinium from scleractinian corals. The remaining eight E. tourneforti colonies harbored Symbiodinium type B1L, while six P. porosa colonies harbored type B1i. Understanding the symbioses between gorgonian corals and Symbiodinium will

    This paper examines the significance of rising relative sea level to the Caribbean region. The various factors contributing to rising relative sea level are explained -- rising eustatic sea level from atmospheric warming, natural subsidence, and manmade subsidence. The possibility of changes in storms is also raised. Possible impacts are discussed, for both wetlands and urban areas. Some developing government policies are described, such as restrictions on coastal development. International research agendas are described. A list of recommended tide-gage stations is presented.

  20. Solar drying in the Caribbean

    SciTech Connect

    Headley, O. )

    1992-03-01

    The United Nations Food and Agricultural Organisation (FAO) has estimated that a quarter of crops are lost through inadequate handling after harvesting. The use of solar dryers can reduce these losses and improve the quality of food. Oliver Headley of the University of the West Indies overviews a range of dryers developed in the Caribbean region. Solar dryers have been used in various parts of the Caribbean for the past eighteen years. The main types are: closed cycle dryers with separate flat plate collector; open cycle dryers with roof vanes against direct sunlight; open cycle dryers with rockbed heat storage units; open cycle dryers with chimneys for air circulation; wire basket dryers with flow through ventilation; barn roof collectors feeding packed bed dryers. During the dry season (January to April), mean daily insolation in a typical Caribbean island is about 25 MJ/m{sup 2}. With such an abundant resource, solar crop drying emerged as a preferred method for the preservation of perishable commodities. In territories without fossil fuel reserves solar energy is an obvious alternative since it does not involve expenditure of scarce foreign exchange. Research and development work in solar crop drying was conducted both at experimental sites in the University and in rural districts throughout the region. Several types of dryer were designed and tested.

  1. Regional strategy tested in Caribbean.

    1984-01-01

    Barbados, St. Vincent, and St. Lucia have joined forces in the world's 1st regional Contraceptive Social Marketing (CSM) effort -- the Caribbean CSM. The Barbados Family Planning Association (BFPS) is overseeing the operation, which begins selling 2 contraceptive pills and a condom in early February. Costs and start-up times were shaved by adopting brand names and advertising materials from Jamaica's highly successful CSM project. Jamaica's popular "Panther" condom and "Perle" oral contraceptive (OC) are being used by the Caribbean CSM project. Perle's 9-year-old package has been redesigned and the Caribbean CSM project also is selling a 2nd, low-dose version called "Perle-LD." The products are manufactured in the US by Syntex as Noriday and Norminest, respectively. But the regional approach's financial gains also had a debit side, most notably a tripling of bureaucratic procedures. Part of project difficulties stem from differences among the 3 Caribbean countries. While sharing a common cultural heritage, St. Lucians speak a patois dialect in addition to the English prevalent on the other islands. The biggest hurdle was overcoming an economic disparity between Barbados and its less affluent neighbors, St. Vincent and St. Lucia. The CSM project decided to try a 2-tier product pricing strategy. In US currency, prices run $1.75 per cycle for both OCs on Barbados, but $1.26 on St. Vincent and St. Lucia. A Panther 3-pack costs 75 cents on Barbados and 42 cents on the othe 2 islands. The project is being promoted with generic family planning media advertisements. The project also has held physician orientation seminars on each island. The pilot program will be accompanied by retailer training seminars. In addition the project may introduce a spermicidal foaming tablet, once the US Food and Drug Administration approvs a new American-made product. The unique Caribbean CSM project may spread an idea as potent as the family planning message. Its success could transmit the

    1984-01-01

    During the last century, three different ways of interpreting the tectonic evolution of the Gulf of Mexico and the Caribbean have been proposed, taking into account the Bailey Willis School of a permanent pre-Jurassic deep sea basin, the Edward Suess School of a subsided continental terrain, and the Alfred Wegener School of continental separation. The present investigation is concerned with an outline of an interpretation which follows that of Pindell and Dewey (1982). An attempt is made to point out ways in which the advanced hypotheses can be tested. The fit of Africa, North America, and South America is considered along with aspects of relative motion between North and South America since the early Jurasic. Attention is given to a framework for reconstructing Caribbean plate evolution, the evolution of the Caribbean, the plate boundary zones of the northern and southern Caribbean, and the active deformation of the Caribbean plate.

  8. HIV / AIDS in the Caribbean.

    By the end of 1998, 33.4 million people worldwide were infected with HIV, 10% more than in 1997, and there were 2.5 million AIDS-related deaths. New estimates by the UN AIDS organization, UNAIDS, and the World Health Organization show that practically every country in the world has been affected by the pandemic. HIV prevalence in eastern Europe, Latin America, and the Caribbean currently appears to be concentrated in, but not limited to, marginalized groups. MAP (Monitoring the AIDS Pandemic), a network of experts with more than 120 members in 40 countries around the world, has estimated that more than 1.6 million people are living with HIV/AIDS in Latin America and the Caribbean, or 5.4% of all HIV/AIDS cases worldwide in January 1998. Infection trends in the area differ both between and within countries. HIV in the region does, however, appear to be mainly in socially and economically marginalized populations, and is most noticeable among men who have sex with men and IV drug users. Evidence also exists that HIV is increasingly spreading among the poor and illiterate segments of society. Infection rates are rising among women, showing that heterosexual transmission is becoming more important. The Caribbean Regional Network of People Living with HIV/AIDS was created out of a 3-day consultation in Port of Spain, Trinidad, sponsored by a number of international organizations. That the number of HIV-positive people in the region is increasing should not be taken lightly. PMID:12349101

    2004-12-01

    The tsunami problem for the coast of the Caribbean basin is discussed. Briefly the historical data of tsunami in the Caribbean Sea are presented. Numerical simulation of potential tsunamis in the Caribbean Sea is performed in the framework of the nonlinear-shallow theory. The tsunami wave height distribution along the Caribbean Coast is computed. These results are used to estimate the far-field tsunami potential of various coastal locations in the Caribbean Sea. In fact, five zones with tsunami low risk are selected basing on prognostic computations, they are: the bay "Golfo de Batabano" and the coast of province "Ciego de Avila" in Cuba, the Nicaraguan Coast (between Bluefields and Puerto Cabezas), the border between Mexico and Belize, the bay "Golfo de Venezuela" in Venezuela. The analysis of historical data confirms that there was no tsunami in the selected zones. Also, the wave attenuation in the Caribbean Sea is investigated; in fact, wave amplitude decreases in an order if the tsunami source is located on the distance up to 1000 km from the coastal location. Both factors wave attenuation and wave height distribution should be taken into account in the planned warning system for the Caribbean Sea.

  12. Summary of Caribbean managers meeting.

    1994-12-01

    The Caribbean Expanded Program on Immunization (EPI) Managers held their 11th meeting in November 1994. The meeting attracted over 80 attendees from all of the member countries, including Puerto Rico (for the first time), representatives of nongovernmental organizations, and technical personnel. Among the achievements cited were the facts that no cases of indigenous measles have been reported in over 3 years in the Caribbean, no cases of paralytic poliomyelitis have been detected in nearly 12 years, progress has been made in the surveillance of fever and rash illnesses, and immunization coverage levels remain high. The main objectives of the meeting were to review the overall EPI program in the Caribbean in order to identify obstacles to achieving program targets and to evaluate continued efforts towards the elimination of measles by 1995. The discussions about measles focused on 1) the surveillance system for the detection of suspected cases, which has improved, but which could be strengthened and 2) the levels of immunization coverage and the continued increase in the number of children who remain susceptible to the disease (each country projected the number of children under age 5 years who would be susceptible by June 1995). Steps to maintain the polio-free status of the area, including maintaining immunization levels of at least 80%, were also reviewed. In addition, concerns about reducing the number of cases of congenital rubella syndrome were addressed with several recommendations including improving active hospital surveillance and developing an appropriate rubella vaccination strategy. Incidence rates for tuberculosis were reported, and the problems of coinfection with HIV and the emergence of drug resistant strains of the disease were discussed. Tuberculosis control programs in the region are generally inadequate, treatment standards have not been implemented, the availability of drugs is limited, and treatment monitoring is not routine.

    1992-01-01

    All islands in the Caribbean except Puerto Rico can be classified as developing islands. Of these islands, all except Trinidad and Tobago are oil importers. Uncertainties concerning uninterrupted oil supply and increasing oil prices causes economic, social and political instability and jeopardizes further development of these islands. The paper discusses the energy situation of the Caribbean islands and presents alternative energy options. Several alternative energy projects financed by local, federal and international organizations are presented. Present and future uses of alternative energy technologies are described in different islands. Barrier which handicap developing and implementing alternative energy sources in the Caribbean are discussed. The potential and possible applications of alternative energy technologies such as: solar-thermal energy, photovoltaics, wind energy, ocean thermal energy conversion (OTEC), ocean currents and tides energy, biomass, peat energy, municipal solid wastes, bioconversion, hydropower, geothermal energy, nuclear energy and energy conservation are discussed in detail as means to alleviate the energy situation in the Caribbean islands.

    2008-12-01

    This paper presents a summary of the forest fire reports in the insular Caribbean derived from both management reports and an analysis of publicly available Moderate Resolution Imaging Spectrodiometer (MODIS) satellite active fire products from the region. A vast difference between the amount of fires reported by land managers and fire points in the MODIS Fire Information for Resource Management System data can be observed. Future research is recommended to better understand the nature of these differences. While there is a general lack of available statistical data on forest fires in the Caribbean, a few general observations can be made: Forest fires occur mainly in dry forest types (500 to 1000 mm of mean annual rainfall). These are also the areas where most human settlements are located. Lowland high forests and montane forests with higher rainfall (1000 and more mm y(-1)) are less susceptible to forest fire, but they can burn in exceptionally dry years. Most of the dry forest ecosystems in the Caribbean can be considered to be fire-sensitive ecosystems, while the pine forests in the Caribbean (Cuba, Dominican Republic, and the Bahamas) are maintained by wildfires. In fire-sensitive ecosystems, uncontrolled burning often encourages the spread of alien invasive species. A Caribbean Fire Management Cooperation Strategy was developed between 2005 and 2006 under auspices of the Food and Agriculture Organization of the United Nations. This regional strategy aims to strengthen Caribbean fire management networking by encouraging closer collaboration among countries with similar ecological conditions. The strategy for the Caribbean identifies a number of research, training, and management activities to improve wildfire management capacity in the Caribbean. PMID:19205174

  16. The Tectonic Evolution of Caribbean Ophiolites

    NASA Astrophysics Data System (ADS)

    Draper, G.

    2001-12-01

    Ophiolitic rocks (associated basalts, gabbros and ultramafic rocks) occur in many areas in the circum-Caribbean and Central America. These ophiolites are derived principally from two oceanic provinces: (1) the Atlantic realm, proto-Caribbean sea that formed when North America separated from South America during the opening of the North Atlantic during Jurassic and Early Cretaceous time. These ophiolites were emplaced during a series of late Cretaceous to early Tertiary arc-continent collisions as the east facing Antilles arc migrated into the Caribbean realm. These occurrences include Guatamala, northern Cuba, northern Hispaniola, and northern Venezuela. (2) the Pacific realm, late Cretaceous Caribbean-Colombian plateau that now occupies the central Caribbean, but outcrops on land in Costa Rica, SW Hispaniola, the Netherlands Antilles and western Colombia. Accretion, emplacement and uplift was aided by their buoyancy and took place at various times during the Caribbean plateau's insertion into the middle American continental gap. A third set of occurrences are more uncertain in origin. The central Hispaniola and SE Puerto Rico ophiolites seem to be Jurassic age oceanic plateau rocks that were emplaced in mid-Cretaceous time during an, subduction polarity reversal episode. The emplacement of the metamorphosed ophiolitic rocks of eastern Jamaica may also be associated with this event, but the adjacent, upper Cretaceous, Bath-Dunrobin complex seems to be more related to the Campanian Yucatan-Antillean arc collision. The ultramafic rocks of Tobago are not oceanic, but represent Alaksan-type, assemblages.

  17. The East Falcon Basin: Its Caribbean roots

    Bartok, P.; Boesi, T.

    1996-08-01

    The East Falcon Basin has been described persistently in the context of the Maracaibo Basin tectonic framework. It is the objective of the present study to demonstrate that the Falcon Basin is, in effect, a Caribbean basin juxtaposed on South America and affected by Caribbean tectonics. The oldest rocks outcropping in the region are Late Paleozoic metamorphic and igneous rocks rafted from northcentral Colombia, Middle Jurassic ophiolite complexes, sediments and metasediments and Cretaceous ophiolites transported by a melange of late Cretaceous to early Tertiary sediments. The south vergence of the Caribbean Nappe province has been documented and extends to the present limit of the Andean uplift and to the southern limit of the Coastal Range. The migrating foredeep that developed during the Paleocene-Eocene deposited dominantly basinal shales and thin sandstones. During the Oligocene the Caribbean faults of the Oca system and conjugates began with a dominantly transtensional regime becoming progressively transpressional by Miocene time. The facies development of the Oligocene-Miocene documents the tectonic history. Unique blocks remained as resistant blocks creating ramparts and modifying the basin configuration. During transpression northward-verging thrusting progressively migrated towards the present coastline. The most evident structures of the region are Caribbean in affinity and combined with the sedimentary history of the region can serve to unravel the complex Caribbean-South American plate interaction.

  18. Poverty, drug abuse fuel Caribbean AIDS outbreak.

    Hatred and fear of homosexuals, together with a fear of losing tourism revenue, drove many high-level policymakers in the Caribbean to ignore the HIV/AIDS in its infancy. With an annual incidence rate of at least 146.6 people per 100,000, the Bahamas now has one of the highest AIDS rates in the world and the highest such rate in the English-speaking Caribbean. AIDS has become the major cause of death for men and women aged 20-44 in the Bahamas. Indeed, throughout the Caribbean, countries like the Bahamas must now cope with a growing AIDS epidemic. UN AIDS Program figures indicate that at least 310,000 people in the Caribbean have either HIV infection or AIDS, and that the prevalence rate among adults is almost 2%. This compares with an estimated 7.4% of the adult population of sub-Saharan Africa which is infected and 0.6% of adults in North America. 65% of reported AIDS cases in the region result from heterosexual intercourse. While the annual number of AIDS cases has been falling in North America over the last several years and rates in Latin America have leveled off, rates in the Caribbean are increasing sharply. Poverty, the population's lack of awareness, low levels of education, internal and international migration, crack cocaine use, promiscuity, high levels of STDs, prostitution, and tourism are also facilitating the spread of HIV in the Caribbean. Social conservatism, mainly in the English-Caribbean, about discussing sex impedes the implementation and success of HIV/AIDS prevention interventions. PMID:12293303

  7. Tsunami Warning Services for the Caribbean Region

    NASA Astrophysics Data System (ADS)

    Whitmore, P. M.; Ferris, J. C.; Weinstein, S. A.

    2007-05-01

    Tsunami warning and watch services are currently provided to the Caribbean region through a collaborative effort between the two NOAA Tsunami Warning Centers (TWCs): the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii, and the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska. The WCATWC, in coordination with the Puerto Rico Seismic Network (PRSN), provides fast-response warning services to the U.S. territories of the Commonwealth of Puerto Rico and the U.S. Virgin Islands (PR/VI). The PTWC provides regional watch services to other countries throughout and surrounding the Caribbean Sea as part of the Intergovernmental Coordination Group for the Caribbean Sea and Adjacent Regions. This collaboration is analogous to the TWC's responsibilities in the Pacific basin: the WCATWC provides fast-response warning services for the U.S. west coast states, Alaska, and British Columbia in Canada, while the PTWC provides regional services for countries throughout and surrounding the Pacific Ocean (as well as a fast-response service for the U.S. State of Hawaii). Caribbean seismic data are transmitted to the TWCs through several means. The PRSN directly exports data to the WCATWC, providing the Center sufficient seismic data for the PR/VI region. Additionally, the PRSN provides the TWCs with data gathered from other Caribbean nations. Using modern communication capabilities, the seismic data can be processed at the TWCs at the same time it is processed locally. Another source of high- quality seismic data is the new USGS nine-station array that circles the region. The Global Seismic Network maintains several stations in Caribbean, Central American, and South American nations which are available in real-time to the TWCs. Unfortunately, sea level data coverage is sporadic in the region. The PR/VI has a relatively dense array of coastal tide gages, but coastal tide gage coverage is very sparse for the rest of the Caribbean basin. Three deep-ocean pressure

  16. Towards indigenous feminist theorizing in the Caribbean.

    PubMed

    Mohammed, P

    1998-01-01

    This theoretical study of feminism in the Caribbean opens by presenting the contemporary image of the Caribbean and then pointing to the continuing influence of the colonial past in the creation of contemporary community and the establishment of identity. The paper continues with a focus on three aspects of identity, or difference, that have influenced the daily articulation of feminism and academic debates. The first concerns the positions taken by women in the region's political struggles. The second is an exploration of the linguistic meanings of the gender discourse within the region. Finally, the essay examines the idea of linguistic difference in light of contemporary Western feminist views of "sexual difference" versus equality. The discussion of each of these issues is grounded in historical analysis and illustrated with specific examples. The study concludes that, in this region, feminism offers a new way to investigate the past while creating challenges and opportunities in the struggle to establish a Caribbean identity.

  20. Caribbean hurricanes: interannual variability and prediction

    NASA Astrophysics Data System (ADS)

    Jury, Mark R.; Rodríguez, Ernesto

    2011-11-01

    Climatic conditions that affect the interannual variability of Caribbean hurricanes are studied. Composite meteorological and oceanographic reanalysis fields are constructed for active and inactive seasons since 1979, and differences are calculated for spring and summer periods to provide guidance in statistical analysis. Predictors are extracted for areas exhibiting high contrast between active and inactive seasons, and intercomparisons are made. Zonal winds north of Venezuela exhibit westerly anomalies prior to active years, so coastal upwelling and the north Brazil current are diminished. Rainfall increases in the Orinoco River basin, creating a fresh warm plume north of Trinidad. The predictor time series are regressed onto an index of Caribbean hurricanes, and multivariate algorithms are formulated. It is found that atmospheric kinematic and convective predictors explain only ˜20% of hurricane variance at 3-5-month lead time. Subsurface ocean predictors offer higher levels of explained hurricane variance (42%) at 3-5-month lead time, using 1-200-m-depth-averaged temperatures in the east Pacific and southern Caribbean. We place the statistical results in a conceptual framework to better understand climatic processes anticipating Caribbean hurricanes.

    1984-01-01

    Rifts form in many different tectonic environments where the lithosphere is put into extension. An outline is provided of the distribution, orientation, and relative ages of 16 Cenozoic rifts along the northern edge of the Caribbean plate and it is suggested that these structures formed successively by localized extension as the Caribbean plate moved eastward past a continental promontory of North America. Evidence leading to this conclusion includes (1) recognition that the rifts become progressively younger westward; (2) a two-phase subsidence history in a rift exposed by upthrusting in Jamaica; (3) the absence of rifts east of Jamaica; and (4) the observation that removal of 1400 km of strike-slip displacement on the Cayman Trough fault system places the Paleogene rifts of Jamaica in an active area of extension south of Yucatan where the rifts of Honduras and Guatemala are forming today.

  3. [Population dynamics and development in the Caribbean].

    PubMed

    Boland, B

    1995-12-01

    The impact is examined of socioeconomic factors on Caribbean population dynamics. This work begins by describing the socioeconomic context of the late 1980s and early 1990s, under the influence of the economic changes and crises of the 1980s. The small size, openness, dependency, and lack of diversification of the Caribbean economies have made them vulnerable to external pressures. The Bahamas and Belize had economic growth rates exceeding 5% annually during 1981-90, but most of the countries had low or negative growth. Unemployment, poverty, the structural adjustment measures adopted in the mid-1980s, and declines in social spending exacerbated general economic conditions. In broad terms, the population situation of the Caribbean is marked by diversity of sizes and growth rates. A few countries oriented toward services and tourism had demographic growth rates exceeding 3%, while at least 7 had almost no growth or negative growth. Population growth rates reflected different combinations of natural increase and migration. Crude death rates ranged from around 5/1000 to 11/1000, except in Haiti, and all countries of the region except Haiti had life expectancies of 70 years or higher. Despite fertility decline, the average crude birth rate was still relatively high at 26/1000, and the rate of natural increase was 1.8% annually for the region. Nearly half of the regional population was under 15 or over 65 years old. The body of this work provides greater detail on mortality patterns, variations by sex, infant mortality, causes of death, and implications for policy. The discussion of fertility includes general patterns and trends, age specific fertility rates, contraceptive prevalence, levels of adolescent fertility and age factors in adolescent sexual behavior, characteristics of adolescent unions, contraceptive usage, health and social consequences of adolescent childbearing, and the search for solutions. The final section describes the magnitude and causes of

    2012-03-01

    Crustaceans of the genus Metanephrops are of great commercial value in some tropical and subtropical regions. With the potential development of a new deep lobster fishery in the Colombian Caribbean Sea, the objective of this work is to describe for first time the patterns of spatial and bathymetric distribution, and diel migratory periodicity of the Caribbean lobster ( M. binghami). Data were collected by trawling in depths between 200 and 550 m (100 m strata intervals) in the Colombian Caribbean Sea. Higher biomass and size of these crustaceans were found between 250 and 350 m, with a maximum at about 300 m. The study offers diel patterns of M. binghami, which suggests nocturnal activity and burrowing during daylight hours.

    Herrick, J. A.; Henton De Angelis, S.; Toscano, M. A.

    2013-12-01

    Floating and washed-up pumices have been reported by scientific expeditions along the Caribbean Sea coast of the Central American Isthmus and the northern coast of South America since at least 1947. Local coastal communities have been utilizing this resource for many years. The rounded and buffered morphology of hand specimens is consistent with water-borne transit. The volcanically active Caribbean and Central American regions provide a number of candidates for source volcanoes and eruptions. We have attempted to identify this source using samples collected from Carrie Bow Cay and Placencia Beach, Belize; Tulum Beach, Mexico; Morrosquillo Bay, Colombia; and Galeta Point, Panama. We have tracked possible transport routes through the use of river drainage and ocean current maps. The criteria for comparing the products of potential source volcanoes (including Atitlán Caldera in Guatemala and Caribbean sources such as Mt. Pelée, Martinique and Soufrière Hills, Montserrat) were developed from the whole rock major and trace element geochemistry and the compositional and textural characteristics of pumice and their constituent minerals and glasses. The largest pumice sample collected from Carrie Bow Cay, Belize, was 18.5x12 cm with the typical, rounded morphology and distinctively stretched vesicles exhibited by this pumice collection.

  6. CARICOF - The Caribbean Regional Climate Outlook Forum

    NASA Astrophysics Data System (ADS)

    Van Meerbeeck, Cedric

    2013-04-01

    Regional Climate Outlook Forums (RCOFs) are viewed as a critical building block in the Global Framework for Climate Services (GFCS) of the World Meteorological Organization (WMO). The GFCS seeks to extend RCOFs to all vulnerable regions of the world such as the Caribbean, of which the entire population is exposed to water- and heat-related natural hazards. An RCOF is initially intended to identify gaps in information and technical capability; facilitate research cooperation and data exchange within and between regions, and improve coordination within the climate forecasting community. A focus is given on variations in climate conditions on a seasonal timescale. In this view, the relevance of a Caribbean RCOF (CARICOF) is the following: while the seasonality of the climate in the Caribbean has been well documented, major gaps in knowledge exist in terms of the drivers in the shifts of amplitude and phase of seasons (as evidenced from the worst region-wide drought period in recent history during 2009-2010). To address those gaps, CARICOF has brought together National Weather Services (NWSs) from 18 territories under the coordination of the Caribbean Institute for Meteorology and Hydrology (CIMH), to produce region-wide, consensus, seasonal climate outlooks since March 2012. These outlooks include tercile rainfall forecasts, sea and air surface temperature forecasts as well as the likely evolution of the drivers of seasonal climate variability in the region, being amongst others the El Niño Southern Oscillation or tropical Atlantic and Caribbean Sea temperatures. Forecasts for both the national-scale forecasts made by the NWSs and CIMH's regional-scale forecast amalgamate output from several forecasting tools. These currently include: (1) statistical models such as Canonical Correlation Analysis run with the Climate Predictability Tool, providing tercile rainfall forecasts at weather station scale; (2) a global outlooks published by the WMO appointed Global Producing

  7. Kinematic reconstruction of the Caribbean region since the Early Jurassic

    2014-05-01

    The Caribbean region results from a complex tectonic history governed by the interplay of the North American, South American and (Paleo-)Pacific plates, between which the Caribbean plate evolved since the early Cretaceous. During its entire tectonic evolution, the Caribbean plate was largely surrounded by subduction and transform boundaries, which hampers a quantitative integration into the global circuit of plate motions. In addition, reconstructions of the region have so far not resulted in a first order kinematic description of the main tectonic units in terms of Euler poles and finite rotation angles. Here, we present an updated, quantitatively described kinematic reconstruction of the Caribbean region back to 200 Ma integrated into the global plate circuit, and implemented with GPlates free software. Our analysis of Caribbean tectonic evolution incorporates an extensive literature review. To constrain the Caribbean plate motion between the American continents, we use a novel approach that takes structural geological observations rather than marine magnetic anomalies as prime input, and uses regionally extensive metamorphic and magmatic phenomena such as the Great Arc of the Caribbean, the Caribbean Large Igneous Province (CLIP) and the Caribbean high-pressure belt as correlation markers. The resulting model restores the Caribbean plate back along the Cayman Trough and major strike-slip faults in Guatemala, offshore Nicaragua, offshore Belize and along the Northern Andes towards its position of origin, west of the North and South American continents in early Cretaceous time. We provide the paleomagnetic reference frame for the Caribbean region by rotating the Global Apparent Polar Wander Path into coordinates of the Caribbean plate interior, Cuba, and the Chortis Block. We conclude that a plate kinematic scenario for a Panthalassa/Pacific origin of Caribbean lithosphere leads to a much simpler explanation than a Proto-Caribbean/Atlantic origin. Placing our

  11. True subduction vs. underthrusting of the Caribbean plate beneath Hispaniola, northern Caribbean

    The Eastern Greater Antilles arc (Hispaniola and Puerto Rico) is bounded by a north-verging accretionary prism on its north side and a south-verging thrust belt (Muertos thrust belt) on its south side. This bivergent geometry has been attributed for the last 30 years to opposing subduction of the North American plate and the Caribbean oceanic interior beneath the island arc at the Muertos margin. Recent observations of seafloor and shallow sub-seafloor deformational features at the Muertos compressive margin together with sandbox kinematic and gravity modeling question the hypothesized subduction of the Caribbean plate's interior beneath the eastern Greater Antilles island arc. To further test the subduction hypothesis, we carried out in 2009 a wide-angle seismic transect across the widest part of the Muertos compressive margin at longitude 69°W. A 2-D forward ray-tracing model of the wide-angle transect outlines the broad-scale crustal structure across the Muertos margin. The Caribbean oceanic slab is imaged beneath the Muertos margin to about 50 km north of the deformation front and down to 19 km depth. A change in crustal p-wave velocity at ~60 km from the deformation front is interpreted as the boundary between the compressive deformed belt and the arc crust. The Caribbean oceanic crust is not seen extending farther north or penetrating the upper mantle. Modeling of ship's gravity data, acquired along the seismic profile, corroborates the seismic results. Any subduction model imply the existence of a regional mass deficit generated by the subducted Caribbean slab beneath the island arc and that variations in the geometry of the subduction angle and the depth are not able to compensate it. Earthquake hypocenter distribution in the Muertos Margin shows diffuse seismicity beneath the island arc, being very hard to identify different clusters and to assign them to different subducted slabs. The diffuse seismicity may be related to the transition between subduction

    2000-10-01

    The vitality of Caribbean coral reefs has undergone a continual state of decline since the late 1970s, a period of time coincidental with large increases in transatlantic dust transport. It is proposed that the hundreds of millions of tons/year of soil dust that have been crossing the Atlantic during the last 25 years could be a significant contributor to coral reef decline and may be affecting other ecosystems. Benchmark events, such as near synchronous Caribbean-wide mortalities of acroporid corals and the urchin Diadema in 1983, and coral bleaching beginning in 1987, correlate with the years of maximum dust flux into the Caribbean. Besides crustal elements, in particular Fe, Si, and aluminosilicate clays, the dust can serve as a substrate for numerous species of viable spores, especially the soil fungus Aspergillus. Aspergillus sydowii, the cause of an ongoing Caribbean-wide seafan disease, has been cultured from Caribbean air samples and used to inoculate sea fans.

  14. Kinematic reconstruction of the Caribbean region since the Early Jurassic

    NASA Astrophysics Data System (ADS)

    Boschman, L. M.; Van Hinsbergen, D. J.

    2013-12-01

    The Caribbean region has a complex tectonic history that resulted from the interplay of the North and South American, the Caribbean, and (Paleo-)Pacific plates. Being largely surrounded by long-lived subduction zones and transform boundaries, reconstructing Caribbean plate motion into the global plate circuit cannot be done using marine magnetic anomalies. Here, we present a fully quantitative, kinematically consistent tectonic reconstruction, back to 200 Ma, using the Atlantic plate circuit as boundary condition. This reconstruction is made in GPlates freeware and all reconstruction files are made available. To restore Caribbean plate motion between the American continents, we use a reconstruction hierarchy based on strike-slip and thrust belt records, using regionally extensive geological phenomena such as the Great Arc of the Caribbean, the Caribbean Large Igneous Province (CLIP) and the Caribeana high-pressure belt as correlation markers. The resulting model restores the Caribbean plate back along the Cayman Trough and strike-slip faults in Guatemala, offshore Nicaragua, offshore Belize and along the Northern Andes towards its position of origin, west of the North and South American continents. Two plate kinematic scenarios for the origin of the Caribbean plate lithosphere are evaluated; an origin from Proto-Caribbean/Atlantic spreading, or from spreading within the Panthalassa domain: we conclude that the latter can provide a simpler explanation. Placing our reconstruction in the most recent mantle reference frames shows that the CLIP erupted 2-3000 km east of, and is probably not the result of the plume head stage of the Galápagos hotspot. Finally, our reconstruction suggests that all modern subduction zones surrounding the Caribbean plate probably formed by inversion of transform faults, two of these (along the southern Mexican and NW South American margins) strongly diachronously as a result of migrating trench-trench-transform triple junctions.

  15. The Caribbean Low-Level Jet Interannual Summer Variability

    NASA Astrophysics Data System (ADS)

    Munoz, E.; Busalacchi, A.

    2006-12-01

    The Caribbean Low-Level Jet (CALLJ) is an intrinsic component of the climate of the Caribbean and Central America region albeit its controls and effects are not well known. The CALLJ is manifested as strong easterly winds in boreal summer at about 925 mb over the Caribbean Sea. Our overarching objectives are: to determine the factors that control the interannual variability of the CALLJ, and to determine the contribution of CALLJ anomalies on summer Caribbean precipitation. An index representing the CALLJ variability is defined as the 925-mb zonal winds averaged over the area: 70°-80° W, 12°-16° N. The summer months corresponding to the upper and lower quartiles of the CALLJ index are chosen from the period 1979-2001 to construct composites. Multivariate principal component analysis is performed with Caribbean 925-mb zonal winds and sea level pressure (SLP) or Caribbean precipitation. It is observed that the main anomalous climate pattern associated with an anomalously strong CALLJ is one with low SLP and warm sea surface temperature (SST) anomalies in the tropical Pacific and high SLP and cool SST anomalies in the tropical Atlantic and the Caribbean. These climate anomalies force remotely the CALLJ through changes in the Caribbean SLP gradients while local feedbacks amplify the effects. Less precipitation over large areas of the Caribbean and Central America is due to stronger vertical wind shear and moisture flux divergence related to a strengthening of the CALLJ. The findings contribute to a better understanding of the climate interactions in the Caribbean region in light of the CALLJ variability and controls.

  16. Caribbean plate tectonics from seismic tomography

    NASA Astrophysics Data System (ADS)

    Ten Brink, U. S.; Villasenor, A.

    2012-12-01

    New seismic tomography in the Caribbean shows close links between the geometry and dynamics of subducting slabs and the geology of the overriding plate. Unlike most oceanic plates, the Caribbean plate lacks identifiable seafloor magnetic anomalies and fracture zones. The plate's history has therefore been inferred primarily from land geology along the plate boundary, which is complicated by large-scale shear deformation, and from finite rotations of surrounding plates.We used more than 14 million arrival times from 300,000 earthquakes to identify P-wave velocity anomalies. We relate the anomalies to the geometry and dynamics of subducting slabs and to patterns of earthquake activity, volcanism, topographic relief, and tectonic deformation. For example, we detect two separate slabs belonging to the North and South American plates, respectively, which appear to be responsible for morphologic and tectonic differences between the arcs of the Northern (from Guadeloupe northward) and Southern (from Dominica southward) Lesser Antilles. Variations in earthquake activity between Haiti and the Dominican Republic can be explained by a change in slab geometry from an underplated slab beneath Haiti to a subducting slab under the Dominican Republic. A shallow tear in the slab may explain the anomalously deep Puerto Rico Trench and the frequent earthquake swarms there. The westward shift in volcanic activity in the Northern Lesser Antilles from the Miocene Limestone Caribbees to the present arc can be attributed to the limit on convective flow imposed by the 3-D geometry of the slab at depth. A thinned South America slab under the southern Lesser Antilles may result from traction imposed on the slab by a wide forearc wedge. Variations in tectonic deformation of northern South America could be related to the location of the Caribbean Large Igneous Province north of the Maracaibo Block.

    Very little has been reported about the health resources available for patients with epilepsy in the five English-speaking southern Caribbean countries of Trinidad and Tobago, Barbados, Grenada, Saint Vincent and the Grenadines, and Saint Lucia. There is no comprehensive resource describing their health systems, access to specialty care, antiepileptic drug (AED) use, and availability of brain imaging and EEG. The purpose of this study was to profile epilepsy care in these countries as an initial step toward improving the standard of care and identifying gaps in care to guide future policy changes. In each southern Caribbean country, we conducted study visits and interviewed health-care providers, government health ministers, pharmacy directors, hospital medical directors, pharmacists, clinic staff, radiologists, and radiology and EEG technicians. Health-care providers completed extensive epilepsy care surveys. The five countries all have integrated government health systems with clinics and hospitals that provide free or heavily subsidized care and AEDs for patients with epilepsy. Only Trinidad and Tobago and Barbados, however, have neurology specialists. The three smaller countries lack government imaging and EEG facilities. Trinidad had up to one-year waits for public MRI/EEG. Government formularies in Grenada, Saint Vincent and the Grenadines, and Saint Lucia are limited to first-generation AEDs. One or more second-line agents are formulary in Trinidad and Barbados. Nonformulary drugs may be obtained for individual patients in Barbados. Grenada, Saint Lucia, and Saint Vincent and the Grenadines participate in an Organization of Eastern Caribbean States formulary purchasing system, which added levetiracetam following the survey. Newer generic AED formulations with the lowest risks for pregnancy malformation were not in use. In conclusion, patients with epilepsy in the southern Caribbean have excellent access to government clinics and hospitals, but AED choices

    The axis of rotation describing relative motion of the Caribbean plate with respect to South America lies in Canada near Hudson's Bay, such that the Caribbean plate moves nearly due east relative to South America [DeMets et al. 2010]. The plate motion is absorbed largely by pure strike slip motion along the El Pilar Fault in northeastern Venezuela, but in northwestern Venezuela and northeastern Colombia, the relative motion is distributed over a wide zone that extends from offshore to the northeasterly trending Mérida Andes, with the resolved component of convergence between the Caribbean and South American plates estimated at ~10 mm/yr. Recent densification of GPS networks through COLOVEN and COCONet including access to private GPS data maintained by Colombia and Venezuela allowed the development of a new GPS velocity field. The velocity field, processed with JPL's GOA 6.2, JPL non-fiducial final orbit and clock products and VMF tropospheric products, includes over 120 continuous and campaign stations. This new velocity field along with enhanced seismic reflection profiles, and earthquake location analysis strongly suggest the existence of an active oblique subduction zone. We have also been able to use broadband data from Venezuela to search slow-slip events as an indicator of an active subduction zone. There are caveats to this hypothesis, however, including the absence of volcanism that is typically concurrent with active subduction zones and a weak historical record of great earthquakes. A single tsunami deposit dated at 1500 years before present has been identified on the southeast Yucatan peninsula. Our simulations indicate its probable origin is within our study area. We present a new GPS-derived velocity field, which has been used to improve a regional block model [based on Mora and LaFemina, 2009-2012] and discuss the earthquake and tsunami hazards implied by this model.

  19. Tectonics and terranes of the Southeastern Caribbean

    Speed, R.C. )

    1993-02-01

    The southeastern Caribbean plate (Ca) is comprised of the following terranes: Tobago, Grenada Basin, St. Vincent, Araya-Margarita, and Paria-Trinidad-Barbardos (PTB). All are alient relative to South America (SA) east of Caracas except for PTB, which is of continental provenance and parautochthonous and lies within the principal movement zone of the Ca-Sa plate boundary. The Tobago terrane extends between the eastern Venezuelan coastline and the Grenada Basin. On its south, the Tobago terrane overrode PTB and the South American passive margin during Neogene oblique collision. The Mesozoic tectonostratigraphy of the Tobago terrane is not unlike that of the Colombian Basin, suggesting the Tobago may belong to the Pacific-derived Caribbean plate. The Grenada Basin terrane consists of Eocene and older oceanic crust that now occupies the southern Lesser Antilles arc platform and the southern Grenada Basin. Such crust abducted southward below the Tobago terrane in mid-Cenozoic time, probably taking up boundary-normal shortening during oblique collision of the Ca and Sa plates. The oceanic crust of the GB terrane arose by backarc spreading of unknown orientation. The St. Vincent terrane extends north in the Antilles from St. Vincent; it is defined by thick crust, perhaps an old arc basement. The Araya-Margarita terrane is a probable subduction complex of Mesozoic age of metamorphism that has been transported far eastward from an unknown site with the Ca plate.

  20. Decadal climate variability in the eastern Caribbean

    NASA Astrophysics Data System (ADS)

    Jury, Mark R.; Gouirand, Isabelle

    2011-11-01

    Rainfall variability in the eastern Caribbean during the 20th century is analyzed using principal component analysis and singular value decomposition. In contrast to earlier studies that used seasonal data, here we employ continuous signal processing. The leading mode is a decadal oscillation related to third and fourth modes of sea level pressure (SLP) and sea surface temperatures (SST) which together identify three zones of action in the Atlantic: 35°N-20°N, 20°N-5°N, and 5°N-20°S. The ability of the ECHAM4.5 model to simulate this signal is investigated. Its decadal variability is also represented through lower-order SLP and SST modes that comprise an Atlantic tripole pattern with lower pressure east of the Caribbean. Composite analysis of high and low phases of the decadal mode reflects a cool east Pacific and a more active Atlantic Intertropical Convergence Zone during boreal summer, conditions that favor the intensification of African easterly waves. The decadal signal has strengthened since 1970, yet the three centers of action in Atlantic SST are relatively unsynchronized.

  1. Women in Physics: A Caribbean Perspective

    NASA Astrophysics Data System (ADS)

    Tanner, Kandice

    2009-03-01

    This paper is concerned with aspects of post-secondary education of women in physics in the Caribbean, focusing more specifically on the main university campuses in Trinidad and Tobago, Jamaica, and Barbados. Within this framework, there are three institutions of tertiary education that provide for undergraduate and post-graduate studies in physics. On average, the bachelor-level graduating class is roughly 40% female. A great majority of these students go on to seek master's degrees in engineering. Among those enrolled in graduate programs featuring research in astronomy, materials science, environmental physics, medical physics, and quantum physics, 58% are female. Significant numbers of women from the selected countries and from the Caribbean region are engaged in bachelor and doctoral programs in physics abroad, but no formal survey is available to provide the relevant quantitative information. However, an attempt will be made to quantify this component. Based in part on personal experience, a comparison will be made between domestic and foreign educational pathways, in terms of access to resources, level of research training, and occupational opportunities following graduation.

    The tsunami problem for the coast of the Caribbean basin is discussed. Briefly the historical data of tsunami in the Caribbean Sea are presented. Numerical simulation of potential tsunamis in the Caribbean Sea is performed in the framework of the nonlinear-shallow theory. The tsunami wave height distribution along the Caribbean Coast is computed. These results are used to estimate the far-field tsunami potential of various coastal locations in the Caribbean Sea. In fact, five zones with tsunami low risk are selected basing on prognostic computations, they are: the bay "Golfo de Batabano" and the coast of province "Ciego de Avila" in Cuba, the Nicaraguan Coast (between Bluefields and Puerto Cabezas), the border between Mexico and Belize, the bay "Golfo de Venezuela" in Venezuela. The analysis of historical data confirms that there was no tsunami in the selected zones. Also, the wave attenuation in the Caribbean Sea is investigated; in fact, wave amplitude decreases in an order if the tsunami source is located on the distance up to 1000 km from the coastal location. Both factors wave attenuation and wave height distribution should be taken into account in the planned warning system for the Caribbean Sea. Specially the problem of tsunami risk for Lesser Antilles including Guadeloupe is discussed.

  3. Late neogene history of the Pacific-Caribbean gateway

    1989-01-01

    Planktic foraminiferal provinces of Caribbean DSDP Hole 502A and East Pacific DSDP Hole 503A have been analyzed and compared with benthic and planktic isotope records, carbonate, hiatus events, and sea level changes. Four major events are evident in the closure history of the Pacific-Caribbean gateway, at 6.2, 4.2, 2.4 and 1.8 Ma. The faunal change at 6.2 Ma coincides with the ??13C shift and is primarily caused by upwelling in the western Caribbean. This suggests restricted circulation of intermediate water and deflection northeastward, strengthening the Gulf Stream as reflected in the first major erosion on Blake Plateau. The second faunal change, at 4.2 Ma, coincides with increased surface water salinity evident in ??18O data and indicates increasingly restricted surface water exchange. Divergence of faunal provinces beginning at 2.4 Ma is marked by increasing abundance of high salinity tolerant species (Globigerinoides ruber) in the Caribbean. This suggests that initial closure of the Pacific-Caribbean gateway and cessation of sustained surface current flow between the Pacific and Caribbean occurred as late as 2.4 Ma. Maximum divergence of faunal provinces begins at 1.8 Ma and continues to the present. This implies that at least incipient littoral-neritic leakage occurred across the Pacific-Caribbean gateway between 2.4 and 1.8 Ma, with final closure by 1.8 Ma. ?? 1989.

  4. Impact of Eastern Caribbean Circulation Seasonality on two Reef Organisms

    The variability of the Caribbean current is under the influence of the fresh water input from the Orinoco and Amazon rivers. Sea Surface Salinity maps of the eastern Caribbean show the seasonal extension of the riverine fresh water across the Caribbean basin, from August to December (wet season). The plume is divided into two main cores: one flows into the Caribbean Sea mostly through the Grenada Passage where it merges with the Caribbean Current while the other core is formed further north by advection of the river plume by the North Brazil Current rings. Due to the presence of fresh water the Caribbean Sea mesoscale activity is strongly increased during the wet season. Therefore, both coral reef ecosystems and coastal flows are under the scope of the large scale flow seasonality. The impact of the flow mesoscale seasonality on reef organisms is studied through two reef organisms: (1) Reef-building coral: Genetic analyzes show that populations of the Caribbean reef-building coral, Acropora palmata, have experienced little or no recent genetic exchange between the western and eastern Caribbean. Western Puerto Rico is identified as an area of mixing between the two subregions. Using a bio- physical coupled model accounting for larvae life history traits, we verify the plausibility of a present day oceanographic barrier caused by the Caribbean Current seasonal variability in the vicinity of Mona Passage. (2) Grouper: Several grouper species form spawning aggregations at the shelf edge of the US Virgin Islands starting at the end of the wet season in December. Using ADCP current measurements and numerical simulations, unusual large 'dispersion' pulses are shown to be associated with the presence of sub-mesoscale coherent features more likely to be formed during the wet season. Spawning occurring during the dry season (January to April) is mostly tide driven, suggesting a limited dispersal.

The Caribbean Basin and the Pacific Rim appear to offer the best total market opportunities considering government energy policies, prices of energy, and consumer attitudes on renewable energy applications. The Caribbean Basin was selected for an industry project opportunity review. This area was selected due to its proximity, renewable resource base, need for energy and growth, and potential for private and multidevelopment bank funding of projects. 3 figs.

    ABSTRACT Objectives: To assess prenatal exposures and potential health outcomes to environmental toxicants such as persistent organic pollutants (POPs), commonly used pesticides, and two heavy metals – mercury (Hg) and lead (Pb) – in 10 Caribbean countries. Subjects and Methods: For each participating Caribbean island, approximately 50 maternal blood and urine samples were collected and analysed for POPs such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), other common classes of pesticides used in the Caribbean such as organophosphates (OP), carbamates, chlorophenols and pyrethroids, and for Hg and Pb. Data obtained from the participating countries were compared with those from the United States of America and Canada. Results: A total of 438 samples were analysed from 10 Caribbean countries. Persistent organic pollutants were detected in almost all samples, however, these were generally low compared with comparable North American results. Evidence of exposure to PBDEs, OPs, carbamates and chlorophenols was also established. Caribbean pyrethroid concentrations were generally much higher than those recorded for North American women. Caribbean Pb maternal blood levels were generally lower than in North America, whereas Hg blood levels were two to three times higher. In almost all of the samples taken in this study, exposures to multiple chemicals were taking place at the same time. Conclusion: This first Caribbean-wide exploratory biomonitoring study on the concentrations of several toxicants in maternal samples taken from 10 Caribbean countries clearly reinforces the need for Caribbean primary care physicians and other public health officials to encourage their patients, and in particular pregnant women, to reduce their exposures to these environmental contaminants as far as it is feasible to do so.

    Coral diseases have contributed significantly to the decline in coral cover in the Caribbean. As many as twenty diseases have been described for Caribbean corals, but few have known etiologies. Here we report on disease signs that were accompanied by high densities of motile, holotrich ciliates, on two species of Caribbean corals, Orbicella faveolata and Siderastrea siderea, which were field collected and maintained in aquaria. A visually estimated increase in ciliate density in the tissue of the coral colonies reflected a putative progression of three `different' disease signs: white-plague-like, brown-band-like, and brown-jelly-like signs. The latter two diseases have previously only been described for corals in the Indo-Pacific, and in aquaria, respectively. Although it remains unclear whether these ciliates are primary pathogens or secondary opportunists, increasing evidence suggests that motile ciliates may play a role in Caribbean-coral diseases.

    Traboulay, EA; Hoyte, OPA

    2015-01-01

    ABSTRACT Objective: Our focus was on the determination of the growing number of youths of every race and ethnicity, diagnosed with obesity and its co-morbidities in the Caribbean. We reviewed the causes and strategies to combat obesity, and the implications of the fast food industry in enabling the escalation of obesity. Methods: We consulted several databases such as PubMed, MEDLINE, the Obesity Gene Map Database, and the USEPA Toxicity Reference Database. Organizations such as the World Health Organization (WHO), Centres for Disease Control and Prevention (CDC), Organization for Economic Co-operation and Development (OECD), and the Pan American Health Organization (PAHO) were used as information sources. Results: Transgenerational effects and triggers like obesogens, pathogens, environmental stress, antibiotics and gut microbiota are some of the causes of obesity, and some of these triggers are imprinted epigenetically early in embryonic development, leading to lifelong obesity. With an estimated population of 42 million in the Caribbean, the economic cost of obesity, including medical, absenteeism, presenteeism, insurance, disability, direct and indirect cost, was estimated at 68.5 billion USD with 88.2 million quality-adjusted life years lost. Conclusion: Genome-wide association studies have established that genetics play a role in the aetiology of this “non-communicable” disease. While the development of personalized interventions according to genotype is futuristic, we must focus on effective nutrition and physical education (PE) classes in schools and establishing monitoring programmes using simple tools such as scales and tape measures as suggested intervention. A Pigovian tax to control the fast food industry is mandatory. Nevertheless, lifestyle adjustment, including alterations in diet and increased physical activity, continues to be a sound recommendation. PMID:26426179

    Ecological factors such as changing climate on land and interspecific competition have been debated as possible causes of postglacial Caribbean extinction. These hypotheses, however, have not been tested against a null model of climate-driven postglacial area loss. Here, we use a new Quaternary mammal database and deep-sea bathymetry to estimate species–area relationships (SARs) at present and during the Last Glacial Maximum (LGM) for bats of the Caribbean, and to model species loss as a function of area loss from rising sea level. Island area was a significant predictor of species richness in the Bahamas, Greater Antilles, and Lesser Antilles at all time periods, except for the Lesser Antilles during the LGM. Parameters of LGM and current SARs were similar in the Bahamas and Greater Antilles, but not the Lesser Antilles, which had fewer estimated species during the LGM than expected given their size. Estimated postglacial species losses in the Bahamas and Greater Antilles were largely explained by inferred area loss from rising sea level in the Holocene. However, there were more species in the Bahamas at present, and fewer species in the smaller Greater Antilles, than expected given island size and the end-Pleistocene/early Holocene SARs. Poor fossil sampling and ecological factors may explain these departures from the null. Our analyses illustrate the importance of changes in area in explaining patterns of species richness through time and emphasize the role of the SAR as a null hypothesis in explorations of the impact of novel ecological interactions on extinction.

  16. African Dust Blows over the Caribbean

    2002-01-01

    Shuttle astronauts frequently track Saharan dust storms as they blow from north Africa across the Atlantic Ocean. Dust palls blowing from Africa take about a week to cross the Atlantic. Recently, researchers have linked Saharan dust to coral disease, allergic reactions in humans, and red tides. The top photograph, a classic image showing African dust over the Caribbean, was taken at a time when few scientists had considered the possibility. The image was taken by Space Shuttle astronauts on July 11, 1994 (STS065-75-47). This photograph looks southwest over the northern edge of a large trans-Atlantic dust plume that blew off the Sahara desert in Africa. In this view, Caicos Island in the Bahamas and the mountainous spines of Haiti are partly obscured by the dust. Closer to the foreground, (about 26 degrees north latitude), the skies are clear. The lower photograph (STS105-723-7) was taken by Space Shuttle astronauts while docked to the International Space Station on August 19, 2001. The spacecraft is over the Atlantic Ocean at roughly 45oN, 60oW. The astronauts were looking obliquely to the south; the boundaries of the dust plumes can be traced visually by the abrupt change from clear to hazy atmosphere-the hazy line marks the northern edge of the dust pall near the Caribbean. Images provided by the Earth Sciences and Image Analysis Laboratory at Johnson Space Center. Additional images taken by astronauts and cosmonauts can be viewed at the NASA-JSC Gateway to Astronaut Photography of Earth.

  17. Potential production of energy cane for fuel in the Caribbean

    Sugarcane presents a tremendous potential as a renewable energy source for the non-oil producing countries of the Caribbean. The energy cane concept is sugarcane managed for maximum dry matter (total fermentable solids for alcohol fuel and combustible solids for electricity) rather than sucrose. The use of sugarcane as a renewable energy source can provide a solution, either partial or total, to the Caribbean energy problem. Sugar cane production and the use of this crop as a renewable energy source are described.

    Geological research in the Caribbean has achieved much. Stratigraphic characterization of lithounits is good, although correlation has proved difficult. Because much of the Cretaceous in both the N. and S. Caribbean is represented by parts of accretionary wedges from extinct arc-systems lithounit correlation is commonly impractical. The complexity of Caribbean Cretaceous tectonics is compounded on both the N. and S. sides by the effects of enormous strike-slip fault systems. Although this phenomenon was early recognized on the north side interpretation of Caribbean evolution embodying this critical observation has awaited synthesis of data related to other phenomena including: 1. Collision of Africa and North America. 2. Formation of the Gulf of Mexico. 3. Continental rupture on the north coast of South America. 4. Motion of South America with respect to North America. 5. Formation of shallow Caribbean ocean floor as an oceanic plateau in the Pacific. 6. Evolution of bounding Cretaceous arc-systems as this oceanic plateau swept into the Atlantic from the Pacific. 7. Collision of these bounding arcs. 8. 1500 km of motion of the Caribbean with respect to North America since the Early Oligocene. 9. 2000 km of motion of the Caribbean with respect to South America over the same interval. 10. Arc histories of Central America and the Lesser Antilles and 11. Northward motion of the Maracaibo block and other responses to the collision of Panama with Colombia within the last 10 Ma. There is no consensus about how the listed phenomena happened, but people are now at a time when testable hypotheses have been advanced about them.

    The Caribbean region is considered to be at risk for avian influenza (AI) due to a large backyard poultry system, an important commercial poultry production system, the presence of migratory birds, and disparities in the surveillance systems. The Caribbean Animal Health Network (CaribVET) has developed tools to implement AI surveillance in the region with the goals to have 1) a regionally harmonized surveillance protocol and specific web pages for AI surveillance on www.caribvet.net, and 2) an active and passive surveillance for AI in domestic and wild birds. A diagnostic network for the Caribbean, including technology transfer and AI virus molecular diagnostic capability in Guadeloupe (real-time reverse transcription-polymerase chain reaction for the AI virus matrix gene), was developed. Between 2006 and 2009, 627 samples from four Caribbean countries were tested for three circumstances: importation purposes, following a clinical suspicion of AI, or through an active survey of wild birds (mainly waders) during the southward and northward migration periods in Guadeloupe. None of the samples tested were positive, suggesting a limited role of these species in the AI virus ecology in the Caribbean. Following low pathogenic H5N2 outbreaks in the Dominican Republic in 2007, a questionnaire was developed to collect data for a risk analysis of AI spread in the region through fighting cocks. The infection pathway of the Martinique commercial poultry sector by AI, through introduction of infected cocks, was designed, and recommendations were provided to the Caribbean Veterinary Services to improve cock movement control and biosecurity measures. The CaribVET and its organization allowed interaction between diagnostic and surveillance tools on the one hand and epidemiologic studies on the other, both of them developed in congruence with regional strategies. Together, these CaribVET activities contribute to strengthening surveillance of avian influenza virus (AIV) in the

    The Working Group 2 (WG2) of the Intergovernmental Coordination Group for the Tsunami and Other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (ICG/CARIBE-EWS) in charge of Tsunami Hazards Assessment, has generated a list of tsunami sources for the Caribbean region. Simulating these worst-case, most credible scenarios would provide an estimate of the resulting effects on coastal areas within the Caribbean. In the past few years, several publications have addressed this issue resulting in a collection of potential tsunami sources and scenarios. These publications come from a wide variety of sources; from government agencies to academic institutions. Although these provide the scientific community with a list of sources and scenarios, it was the interest of the WG2 to evaluate what has been proposed and develop a comprehensive list of sources, therefore leaving aside proposed scenarios. The seismo-tectonics experts of the Caribbean within the WG2 members were tasked to evaluate comprehensively which published sources are credible, worst-cases, and consider other sources that have been omitted from available reports. Among these published sources are the GEM Faulted Earth Subduction Characterization Project, and the LANTEX/Caribe Wave annual exercise publications (2009-2015). Caribbean tectonic features capable of generating tsunamis from seismic dislocation are located along the Northeastern Caribbean, the Lesser Antilles Trench, and the Panamá and Southern Caribbean Deformed Belts. The proposed sources have been evaluated based on historical and instrumental seismicity as well as geological and geophysical studies. This paper presents the sources and their justification as most-probable tsunami sources based on the context of crustal deformation due to Caribbean plate interacting with neighboring North and South America plates. Simulations of these sources is part of a subsequent phase in which effects of these tectonically induced tsunamis

    The order Amphipoda is one of the most diverse within Peracarids, and comprises 6950 described marine species. Amphipod research in the Caribbean Sea began in the late 1800s, but has increased significantly since 1980. In this study, we analized the amphipod biodiversity (Caprellidea, Gammaridea, Hyperiidea, and Ingolfiellidea) of the Caribbean Sea. For this, we compiled available data on species diversity of marine amphipods (data bases: WoRMS and OBIS and published species lists) into a comprehensive taxonomic list by country for the ecoregions of the Caribbean. Additionally, we analized the relative contribution of each country to regional diversity and the rate of discovery of new species. The Caribbean amphipod fauna is composed of 535 species within 236 genera and 73 families for the higher taxon. The Western Caribbean ecoregion holds the largest diversity (282 species), while the Eastern Caribbean recorded the lowest one (73). Mexico and Venezuela recorded the largest number of species with 266 and 206, respectively. Twelve countries had less than 50 species. The richest suborder is the Gammaridea with 381 species followed by the suborder Hyperiidea with 116. From the total of 535 amphipod species reported for the Caribbean region, 218 have the Caribbean as the holotype locality, and 132 are endemic (about 25% of the total). Areas of higher diversity seem to be concentrated along the Mexican Caribbean, Cuba and the Northern coast of South America (Venezuela-Colombia); however, such pattern is most likely reflecting local collection efforts and taxonomic expertise rather than actual distribution. Knowledge of amphipod species is mostly limited to shallow, near-shore waters, with little infonnation available on the deep sea fauna. Regional research priorities for this group should be focused on completing shallow water coastal inventories of species in Central America and the Greater and Lesser Antilles. In addition, sampling the deep sea ecosystems should

  2. Reproductive ecology of Caribbean reef corals

    1986-08-01

    The last decade has seen a resurgence of interest in the processes of sexual reproduction by scleractinian reef corals. Earlier investigations had focused fortuitously on brooding (planulating) species, which resulted in the general misconception that brooding was the main form of larval development of reef corals. More recent work on Indo-Pacific species has shown broadcast spawning and short annual reproductive periods to predominate. This report presents the reproductive patterns of eleven Caribbean coral species and attempts to explain the adaptive features and selective pressures that have led to the evolution of the four reproductive patterns described to date: (a) hermaphroditic broadcasters; (b) gonochoric broadcasters; (c) hermaphroditic broadcasters; (b) gonochoric brooders. Both (a) and (b) correlate with large colony size and short annual spawning periods; and (c) and (d) correlate with small colony size, multiple planulating cycles per year, and occupation of unstable habitats. Selection for outcrossing between long-lived individuals is proposed as the reason for gonochorism and for synchronous spawning of hermaphroditic broadcasters, and also for the large amount of sperm produced by hermaphroditic brooders. Selection for high rates of local recruitment is proposed as the force behind the evolution of brooding by species inhabiting unstable habitats and suffering high rates of adult mortality.

    A near vertical view of the Caribbean coast of Venezuela is seen in this Skylab 3 Earth Resources Experiment Package S190-B (five-inch earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The large body of water is the Golfo de Venezuela; and the major land mass is the Peninsula de Paraguana. The view is looking northward from the mouth of the Golfete de Coro and Punta Cardon to Punta Macolia. The peninsula is connected to the Venezuelan mainland by the narrow strip of land in the most easterly corner of the picture. The dry, arid climate of the peninsula is indicated by sparse vegetation and the abundance of sand dunes. The highest point is about 2,700 feet above the sea and is the conspicuous black spot. Old raised shorelines features appear as streaks parallel to the Golfete de Coro. Water of the Golfete de Coro is red from the high sediment content. The streaks in the water off the peninsula is apparently an effect of wind which is blowing sand and w

  4. Toward a Caribbean psychology: an African-centered approach.

    PubMed

    Sutherland, Marcia Elizabeth

    2011-01-01

    Although the Americas and Caribbean region are purported to comprise different ethnic groups, this article’s focus is on people of African descent, who represent the largest ethnic group in many countries. The emphasis on people of African descent is related to their family structure, ethnic identity, cultural, psychohistorical, and contemporary psychosocial realities. This article discusses the limitations of Western psychology for theory, research, and applied work on people of African descent in the Americas and Caribbean region. In view of the adaptations that some people of African descent have made to slavery, colonialism, and more contemporary forms of cultural intrusions, it is argued that when necessary, notwithstanding Western psychology’s limitations, Caribbean psychologists should reconstruct mainstream psychology to address the psychological needs of these Caribbean people. The relationship between theory and psychological interventions for the optimal development of people of African descent is emphasized throughout this article. In this regard, the African-centered and constructionist viewpoint is argued to be of utility in addressing the psychological growth and development of people of African descent living in the Americas and Caribbean region.

    Eddy motion in the Caribbean Sea is described on the basis of sea level anomalies deduced from ERS-1 altimetry data corrected with TOPEX/Poseidon data during the 15 months of the Exact Repeat Mission (October 1992 to December 1993). Both cyclones and anticyclones were observed in the satellite data as anomalies originating in the Venezuelan Basin or entering the Caribbean through the Antillean passages, mainly the St. Lucia Channel, Anegada Passage, and north of Trinidad. The diameter of the eddies ranged from a few tens of kilometers to 700 km. Advection speeds were typically 20-30 cm s-1 and the eddies were energetic (kinetic energy > 0.6 m2 s-2). Their lifetime of 3-4 months was determined, in general, by their interaction with topography. Most eddy activity was eroded and disappeared at the Central American Rise area, although a few eddies crossed into the Cayman Sea through the Chibcha Channel. Some eddies also entered the Cayman Sea from outside the Caribbean through the Windward Passage. The Panama-Colombia Gyre was evident only during the tropical rainy season. A large cyclonic eddy was formed there during the period of maximum precipitation, when strong meridional salinity and wind speed gradients occurred. Eddy production in the central Caribbean appears to be associated with the interaction of the meandering Caribbean Current and the strong wind curl.

    2016-01-01

    In 2011 and 2015, the nations of the Caribbean Sea were overwhelmed by the unprecedented quantity of Sargassum that washed ashore. This issue prompted international discussion to better understand the origins, distribution, and movement of Sargassum, a free-floating brown macro alga with ecological, environmental, and commercial importance. In the open ocean, Sargassum mats serve a vital ecological function. However, when large quantities appear onshore without warning, Sargassum threatens local tourist industries and nearshore ecosystems within the Caribbean. As part of the international response, this project investigated the proliferation of this macro alga within the Caribbean Sea from 2003-2015, and used NASA Earth observations to detect and model Sargassum growth across the region. The Caribbean Oceans team calculated the Floating Algal Index (FAI) using Terra Moderate Resolution Imaging Spectroradiometer (MODIS) data, and compared the FAI to various oceanic variables to determine the ideal pelagic environment for Sargassum growth. The project also examined the annual spread of Sargassum throughout the region by using Earth Trends Modeler (ETM) in Clark Labs' TerrSet software. As part of the international effort to better understand the life cycle of Sargassum in the Caribbean, the results of this project will help local economies promote sustainable management practices in the region.

    This study examined demographic and denominational differences in religious involvement (i.e., organizational, non-organizational, subjective) among Caribbean Blacks (Black Caribbeans) residing in the U.S. using data from the National Survey of American Life. Caribbean Blacks who were born in the U.S. had lower levels of religious involvement than those who immigrated and respondents originating from Haiti (as compared to Jamaica) had higher levels of religious involvement, while persons from Trinidad-Tobago reported lower service attendance than did Jamaicans. Older persons, women and married persons generally demonstrated greater religious involvement than their counterparts, while highly educated respondents expressed lower levels of self-rated religiosity. Denominational differences indicated that Baptists reported high levels of religious involvement; however, in several cases, Pentecostals and Seventh Day Adventists reported greater involvement.

By July 1990, 1702 AIDS cases had been reported to CAREC, out of 5726 cases in 27 Caribbean countries excluding Puerto Rico. 90% of the cases occurred in the 5 largest, Bahamas, Barbados, Bermuda, Jamaica and Trinidad and Tobago. Initially the transmission pattern was predominantly among male homo- and bisexuals, but not it is mostly heterosexual with a growing mother-to-child transmission. All countries are now screening blood or blood donors. CAREC is coordinating epidemiologic surveillance, helping national laboratories to screen by providing confirmatory tests, providing culture-relevant health education materials and AIDS information, assisting with surveys, holding training workshops for health care workers, and assisting member countries in designing education and counseling programs for high risk women.

    Medical journals and other sources do not show evidence that cholera occurred in Haiti before 2010, despite the devastating effect of this disease in the Caribbean region in the 19th century. Cholera occurred in Cuba in 1833–1834; in Jamaica, Cuba, Puerto Rico, St. Thomas, St. Lucia, St. Kitts, Nevis, Trinidad, the Bahamas, St. Vincent, Granada, Anguilla, St. John, Tortola, the Turks and Caicos, the Grenadines (Carriacou and Petite Martinique), and possibly Antigua in 1850–1856; and in Guadeloupe, Cuba, St. Thomas, the Dominican Republic, Dominica, Martinique, and Marie Galante in 1865–1872. Conditions associated with slavery and colonial military control were absent in independent Haiti. Clustered populations, regular influx of new persons, and close quarters of barracks living contributed to spread of cholera in other Caribbean locations. We provide historical accounts of the presence and spread of cholera epidemics in Caribbean islands. PMID:22099117

  18. Petroleum in the Caribbean Basin: Further exploration justified?

    After more than half a century of exploration for petroleum in that part of the Caribbean Basin covered by this review, the prospects for substantial discoveries remain low. Only Barbados has had modest but sustained production of oil and gas. In Hispaniola minor production from small prospects lasted briefly. Exploration in the northeast Caribbean has not resulted in discoveries. Similar exploration in Puerto Rico and, on a more extensive scale, in Jamaica, has also failed to show positive results. On the Nicaragua Rise (Mosquitia, Tela Basins) drilling has produced shows but no production, a situation also evident in Belize. Nevertheless, examination of these results, in the context of the regional geology of the Caribbean Basin, suggests there are areas where further exploration is justified.

  19. Linking the Galapagos hotspot and the Caribbean Plateau

    Wide agreement exists that the Caribbean plate has a Pacific origin and that parts of it depict an igneous Plateau of up to 20 km thick crust. However, the origin of this thickened crust remains debated. One of the first suggestions for its origin was the arrival of a plume, whose remnant might be the Galapagos hotspot. More recently, it has been argued that reconstruction models predicted the Galapagos hotspot a thousand or more kilometres away from the Caribbean plate at the time of Plateau formation (~88 ?? 94 Ma). These authors primarily relied on the Caribbean Plateau moving into its present position relative to the Americas only in the last few million years. Secondarily, the authors assumed that the hotspot was fixed in an Indian-Atlantic hotspot reference frame. Here, we explore the idea that the Plateau moved into position around the time of the initiation of convergence between the North and South America, about 54.5 Ma. In addition, we adopt a fixed Pacific hotspot reference frame and compare our results to the recently developed Global Moving Hotspot Reference Frame. We show that both frames lead to good correlations between the paleo-positions of the Caribbean Plate and the Galapagos hotspot. As this result is consistent with abundant geochemical evidence that lends support for both a plume origin as well as the similarity between the Galapagos hotspot and rocks from the Plateau itself, we argue that alternative mechanisms to explain the thickened crust of the Caribbean Plateau are unnecessary. Additionally, based on our new plate reconstruction model, we present an age distribution of the lithosphere underneath the thickened crust of the Caribbean Plateau that has remained speculative until now.

  20. Interannual Caribbean salinity in satellite data and model simulations

    Aquarius sea surface salinity (SSS) reveals the presence of interannual variations in the Caribbean with about 0.5 psu change between salty and fresh events, which propagate westward across that basin at an average speed of 11 cm/s and are preceded by corresponding SSS anomalies east of the Lesser Antilles. These upstream SSS anomalies are produced by interannual changes in the Amazon plume. Their presence is verified using in situ measurements from the northwest tropical Atlantic station. In contrast to SSS, which displays westward propagation, SST changes almost immediately across the Caribbean, suggesting large-scale atmospheric processes have a primary role in regulating interannual SST in contrast to SSS. A global 1/10° mesoscale ocean model is used to quantify possible origination mechanisms of the Caribbean salinity anomalies and their fate. Simulations confirm that they are produced by anomalous horizontal salt advection, which conveys these salinity anomalies from an area east of the Lesser Antilles across the Caribbean. Anomalous horizontal advection is dominated by mean currents acting on anomalous salinity. The model suggests that interannual Caribbean salinity anomalies eventually enter the Florida Current and reach the Gulf Stream 6-12 months after crossing the central Caribbean. Previous studies link the origin of salinity anomalies in the Amazon plume to variations in the annual freshwater discharge from the continent. In this model interannual discharge variations are absent while simulated SSS variability is in line with observations. This suggests that interannually forced ocean dynamics plays a key role in river plume variability and its spatial dispersion.

  1. Pigment distribution in the Caribbean sea: Observations from space

    NASA Astrophysics Data System (ADS)

    Müller-Karger, F. E.; McClain, C. R.; Fisher, T. R.; Esaias, W. E.; Varela, R.

    The Caribbean is a semi-enclosed tropical sea which is generally considered oligotrophic, but that is influenced by nearly 20% of the annual discharge of the world's rivers (Amazon and Orinoco Rivers) and by seasonal upwelling along the southern margin. To investigate the role of these nutrient sources on the productivity of the region, we mapped the distribution of pigments in the eastern Caribbean (east of 80° W) using a series of Coastal Zone Color Scanner (CZCS) images collected between November 1978 and December 1982. Five additional images were examined for the period 1983-1986. The images revealed a seasonal cycle in the spatial structure of near-surface pigment. During January-May, there were high pigment concentrations (> 0.5 mg m -3) along the continental margin (south of 14°N), where upwelling occurred. Very little pigment (< 0.2 mg m -3) was found in the northern half of the Caribbean at this time. The frequency of upwelling-related blooms decreased after July, but the seasonally-expanding plume of the Orinoco River dispersed pigment over a large area of the Caribbean (> 3 × 10 5 km 2). This plume reached Puerto Rico around September-October and drifted westward, slowly losing its color signature. We estimate that the discharge of the Orinoco contributes 2-12% of the daily nitrogen requirements of the phytoplankton growing in the river plume, and leads to the fixation of 7-29 × 10 5 tons of carbon per year. The rest of the nitrogen demand appears to be met by nitrogen cycling. The large-scale (> 100 km) pigment distribution patterns in the Caribbean Sea seem to be controlled by wind stress, flux of water through the basin, and river discharge. Westward advection of Atlantic water probably dominates the flow during the first half of the year, restricting the dispersal of blooms to the southern half of the Caribbean while flushing the central and northern portions. As the influx of Atlantic water decreases in the second half of the year, local Ekman

    There are four Jurassic to Recent basin-forming periods in northern Central America (honduras, Honduran Borderlands, Belize, Guatemala, northern Nicaragua): (1) Middle Jurassic-Early Cretaceous rifting and subsidence along normal faults in Honduras and Guatemala; rifts are suggested but are not well defined in Honduras by the distribution of clastic sediments and associated volcanic rocks. Rifting is attributed to the separation of Central America from the southern margin of the North American plate; (2) Cretaceous subsidence recorded by the development of a Cretaceous carbonate platform in Honduras, Guatemala, and Belize; subsidence is attributed to thermal subsidence of the rifted margins of the various blocks; (3) Late Cretaceous-Recent development of a volcanic arc along the western margin of Middle America and the northern margin of Honduras; (4) Late Cretaceous large-scale folding in Honduras, ophiolite obduction, and formation of a foredeep basin in Guatemala (Sepur trough); deformation is attributed to the collision between a north-facing arc in northern Honduras and the Nicaraguan Rise and the passive margin of Guatemala and Belize; and (5) Eocene to Recent strike-slip faulting along the present-day North American-Caribbean plate boundary in Guatemala, northern Honduras, and Belize. Strike-slip faults and basins form a California-type borderlands characterized by elongate basins that appear as half-grabens in profile. Counterclockwise rotation of the central honduras plateau, a thicker and topographically higher-than-average block within the plate boundary zone, is accommodated by rifting or strike-slip faults at its edges.

  3. Extension in Mona Passage, Northeast Caribbean

    As shown by the recent Mw 7.0 Haiti earthquake, intra-arc deformation, which accompanies the subduction process, can present seismic and tsunami hazards to nearby islands. Spatially-limited diffuse tectonic deformation within the Northeast Caribbean Plate Boundary Zone likely led to the development of the submerged Mona Passage between Puerto Rico and the Dominican Republic. GPS geodetic data and a moderate to high level of seismicity indicate that extension within the region is ongoing. Newly-collected high-resolution multibeam bathymetry and multi-channel seismic reflection profiles and previously-collected samples are used here to determine the tectonic evolution of the Mona Passage intra-arc region. The passage is floored almost completely by Oligocene-Pliocene carbonate platform strata, which have undergone submarine and subaerial erosion. Structurally, the passage is characterized by W- to NNW-trending normal faults that offset the entire thickness of the Oligo-Pliocene carbonate platform rocks. The orientation of these faults is compatible with the NE-oriented extension vector observed in GPS data. Fault geometry best fits an oblique extension model rather than previously proposed single-phase, poly-phase, bending-moment, or rotation extension models. The intersection of these generally NW-trending faults in Mona Passage with the N-S oriented faults of Mona Canyon may reflect differing responses of the brittle upper-crust, along an arc-forearc rheological boundary, to oblique subduction along the Puerto Rico trench. Several faults within the passage, if ruptured completely, are long enough to generate earthquakes with magnitudes on the order of Mw 6.5-7. ?? 2010.

Three major themes emerge: (a) the effects of colonialism on the Caribbean psyche; (b) decolonization of psychiatric public policy, including innovative treatment approaches, deinstitutionalization, and community and policy responses to mental health issues; and (c) the nature and epidemiology of psychiatric pathology among contemporary Caribbean people, with particular focus on migration, genetic versus social causation of psychosis and personality disorders, and mechanisms of resilience and social capital. Caribbean transcultural psychiatry illustrates the principles of equipoise unique to developing countries that protect the wellness and continued survival of postcolonial Caribbean people.

    Identifying general patterns of colonization and radiation in island faunas is often hindered by past human-caused extinctions. The insular Caribbean is one of the only complex oceanic-type island systems colonized by land mammals, but has witnessed the globally highest level of mammalian extinction during the Holocene. Using ancient DNA analysis, we reconstruct the evolutionary history of one of the Caribbean's now-extinct major mammal groups, the insular radiation of oryzomyine rice rats. Despite the significant problems of recovering DNA from prehistoric tropical archaeological material, it was possible to identify two discrete Late Miocene colonizations of the main Lesser Antillean island chain from mainland South America by oryzomyine lineages that were only distantly related. A high level of phylogenetic diversification was observed within oryzomyines across the Lesser Antilles, even between allopatric populations on the same island bank. The timing of oryzomyine colonization is closely similar to the age of several other Caribbean vertebrate taxa, suggesting that geomorphological conditions during the Late Miocene facilitated broadly simultaneous overwater waif dispersal of many South American lineages to the Lesser Antilles. These data provide an important baseline by which to further develop the Caribbean as a unique workshop for studying island evolution. PMID:25904660

    The primary objectives of the Caribbean Tourist Facilities (CTF) project were to develop and publish materials and conduct workshops on solar energy and conservation technologies that would directly address the needs and interests of tourist facilities in the Caribbean basin. Past contacts with the Caribbean and US tourist industries indicated that decision-makers remained unconvinced that renewable technologies could have a significant impact on development and operation costs or that renewable energy products and services suited their needs. In order to assure that the materials and programs developed were responsive to the Caribbean tourist industry and US conservation and renewable energy industries, marketing research with potential end users and the organizations and associations that serve those users was included as an underlying task in the project. The tasks outlined in the CTF Statement of Work included conference planning, gathering of field data, development of educational materials, and conduct of workshop(s). In addition to providing a chronicle of the fulfillment of those tasks, this final report includes suggestions for distributing the documents developed during the project, venues for future workshops, and other technology transfer and market influence strategies. 3 refs.

    Depend on the month, African desert dust affect different parts of the North Atlantic Ocean. From December to April, Saharan dust outbreaks are often reported over the amazon basin and from May to November over the Caribbean islands and the southern regions of USA. This annual oscillation of Saharan dust presence, related to the ITCZ position, is perturbed some time, during March. Indeed, over Guadeloupe, the air quality network observed between 2007 and 2012 several dust events during March. In this paper, using HISPLIT back trajectories, we analyzed air masses trajectories for March dust events observed in Guadeloupe, from 2007 to 2012.We observed that the high pressure positions over the Atlantic Ocean allow the transport of dusty air masses from southern region of West Africa to the Caribbean Sea with a path crossing close to coastal region of French Guyana. Complementary investigations including the relationship between PM10 concentrations recorded in two sites Pointe-a-Pitre in the Caribbean, and Cayenne in French Guyana, have been done. Moreover we focus on the mean delay observed between the times arrival. All the results show a link between pathway of dusty air masses present over amazon basin and over the Caribbean region during several event of March. The next step will be the comparison of mineral dust composition for this particular month.

    Oblique collision between the southern Lesser Antilles arc and continental South America controlled tectonics from end Eocene to present in the S.E. Caribbean. There, terranes are from N to S: 1. magmatic arc platform (Margarita to Grenadines); 2. forearc basin; 3. ophiolite belt that may be basement to the forearc basin; 4. accretionary prism whose structurally shallow rocks near Barbados may be equivalent to formerly deep-seated metasediments exposed in Tobago, Trinidad, Paria, and Araya; 5. foreland thrust belt in the slope and shelf cover of S. America; 6. E. Venezuelan-Trinidad foreland basin; and 7. S. American shield. The boundary between terranes 4 and 5 is probably a N-dipping thrust. Early in the Eocene, the southern L.A. arc was probably intra-Atlantic, NE-trending, and positioned offshore of the N-facing passive margin of northern S. America. The arc moved SE relative to S. America, first consuming Mesozoic oceanic lithosphere and accreting sediment of S. American provenance to its forearc, then riding obliquely over the slope and outer shelf of the continental passive margin. Major effects of the collision are uplift of deep-seated arc rocks, imbrication of arc elements, generation of the El Pilar tear fault, and foreland contraction and basining. The southern Lesser Antilles arc was not attached to a far traveled Caribbean plate of Pacific provenance. This implies the existence of boundaries within the Caribbean between an exotic Caribbean plate and the southern Antillean arc.

    Identifying and dating first human colonization of new places is challenging, especially when group sizes were small and material traces of their occupations were ephemeral. Generating reliable reconstructions of human colonization patterns from intact archaeological sites may be difficult to impossible given post-depositional taphonomic processes and in cases of island and coastal locations the inundation of landscapes resulting from post-Pleistocene sea-level rise. Paleoenvironmental reconstruction is proving to be a more reliable method of identifying small-scale human colonization events than archaeological data alone. We demonstrate the method through a sediment-coring project across the Lesser Antilles and southern Caribbean. Paleoenvironmental data were collected informing on the timing of multiple island-colonization events and land-use histories spanning the full range of human occupations in the Caribbean, from the initial forays into the islands through the arrival and eventual domination of the landscapes and indigenous people by Europeans. In some areas, our data complement archaeological, paleoecological, and historical findings from the Lesser Antilles and in others amplify understanding of colonization history. Here, we highlight data relating to the timing and process of initial colonization in the eastern Caribbean. In particular, paleoenvironmental data from Trinidad, Grenada, Martinique, and Marie-Galante (Guadeloupe) provide a basis for revisiting initial colonization models of the Caribbean. We conclude that archaeological programs addressing human occupations dating to the early to mid-Holocene, especially in dynamic coastal settings, should systematically incorporate paleoenvironmental investigations.

  15. Dust and Air Quality Forecasting in the Eastern Caribbean

    Significant amounts of dust travel across the northern tropical Atlantic to the Caribbean every year from the Sahara region. These dust concentrations in the Caribbean often exceed United States Environmental Protection Agency (EPA) standards for particulate matter of 2.5 microns or less (PM 2.5) which could have serious implications for human health in the region. Air pollution has become a major issue in the Caribbean because of urban development, increased vehicle emissions and growing industrialisation. However, the majority of territories in the Caribbean do not have routine air quality monitoring programmes and several do not have or enforce air quality standards for PM2.5 and PM10. As a result, the Caribbean Institute for Meteorology and Hydrology (CIMH) has taken the initiative to provide dust and air quality forecasts for the Eastern Caribbean using the advanced WRF-Chem modeling system. The applications of the WRF-Chem modelling system at CIMH that are currently being focused on are the coupled weather prediction/dispersion model to simulate the release and transport of constituents, especially Saharan dust transport and concentration; and as a coupled weather/dispersion/air quality model with full interaction of chemical species with prediction of particulate matter (PM2.5 and PM10). This will include future applications in the prediction of ozone (O3) and ultraviolet (UV) radiation as well as examining dust radiative forcing and effects on atmospheric precipitation and dynamics. The simulations are currently initialised at 00Z for a seven day forecast and run at 36 km resolution with a planned second domain (at 12 km) for air quality forecasts. Preliminary results from this study will be presented and compared to other dust forecast models currently used in other regions. This work also complements in situ measurements at Ragged Point, Barbados (oldest dust record since 1965), Martinique, Guadeloupe, French Guiana and Puerto Rico. The goal of this study

  16. Educating and Preparing for Tsunamis in the Caribbean

    The Caribbean and Adjacent Regions has a long history of tsunamis and earthquakes. Over the past 500 years, more than 75 tsunamis have been documented in the region by the NOAA National Geophysical Data Center. Just since 1842, 3446 lives have been lost to tsunamis; this is more than in the Northeastern Pacific for the same time period. With a population of almost 160 million, over 40 million visitors a year and a heavy concentration of residents, tourists, businesses and critical infrastructure along its shores (especially in the northern and eastern Caribbean), the risk to lives and livelihoods is greater than ever before. The only way to survive a tsunami is to get out of harm's way before the waves strike. In the Caribbean given the relatively short distances from faults, potential submarine landslides and volcanoes to some of the coastlines, the tsunamis are likely to be short fused, so it is imperative that tsunami warnings be issued extremely quickly and people be educated on how to recognize and respond. Nevertheless, given that tsunamis occur infrequently as compared with hurricanes, it is a challenge for them to receive the priority they require in order to save lives when the next one strikes the region. Close cooperation among countries and territories is required for warning, but also for education and public awareness. Geographical vicinity and spoken languages need to be factored in when developing tsunami preparedness in the Caribbean, to make sure citizens receive a clear, reliable and sound science based message about the hazard and the risk. In 2006, in the wake of the Indian Ocean tsunami and after advocating without success for a Caribbean Tsunami Warning System since the mid 90's, the Intergovernmental Oceanographic Commission of UNESCO established the Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS). Its purpose is to advance an end to end tsunami

  17. Deformation of the Caribbean region: One plate or two?

    1998-11-01

    New deep-penetrating high-resolution multichannel seismic reflection data collected in the eastern Caribbean during R/V Ewing cruise EW9501 imaged both the crustal structure and overlying stratigraphic successions. On the basis of this new multichannel seismic data, we define the geologic development of the Beata Ridge and Venezuelan basin. The Caribbean crust was formed by seafloor spreading in Late Jurassic Early Cretaceous time. Prior to the Senonian, widespread and rapid eruption of basaltic flows began in concert with extensional deformation of the Caribbean crust. Thick volcanic wedges characterized by divergent reflectors are observed along the boundary that separates rough from smooth oceanic crust, are coincident with an abrupt shallowing of the Moho, and appear to be bounded by a large, northwest-dipping fault system. The locus of major extensional deformation migrated through time from the Venezuelan basin to the western flank of the Beata Ridge. Extensional unloading of the Beata Ridge footwall caused uplift and rotation of the ridge. Sediment thicknesses and stratal geometry observed across the Venezuelan basin and Beata Ridge suggest that the majority of the deformation in this region occurred during and soon after the emplacement of the volcanics. Minor fault reactivation in the Neogene along the eastern flank of the Beata Ridge is associated with an accommodation zone (i.e., tear fault) that records a change in the deformation style from bending and subduction of the Caribbean plate along the Muertos Trough south of Puerto Rico to compressional deformation and obduction of the Caribbean plate south of Hispaniola. We propose that this difference in deformational style is, in part, a consequence of the thicker crust on the Beata Ridge, which is more resistant to subduction.

  18. Curie point depth estimation of the Eastern Caribbean

    2013-04-01

    In this paper we present an estimation of the Curie point depth (CPD) on the Eastern Caribbean. The estimation of the CPD was done from satellite magnetic anomalies, by the application of the Centroid method over the studied area. In order to calculate the CPD, the area was subdivided in square windows of side equal to 2°, with an overlap distance of 1° to each other. As result of this research, it was obtained the Curie isotherm grid by using kriging interpolation method. Despite of the oceanic nature of the Eastern Caribbean plate, this map reveals important lateral variations in the interior of the plate and its boundaries. The lateral variations observed in CPD are related with the complexity of thermal processes in the subsurface of the region. From a global perspective, the earth's oceanic provinces show a CPD's smooth behavior, excepting plate boundaries of these oceanic provinces. In this case, the Eastern Caribbean plate's CPD variations are related to both: Plate's boundaries and plate's interior. The maximum CPD variations are observed in the southern boundary of Caribbean plate (9 to 35 km) and over the Lesser Antilles and Barbados prism (16 to 30 km). This behavior reflects the complex geologic evolution history of the studied area, in which has been documented the presence of extensive mantle of basalt and dolerite sills. These sills have been originated in various cycles of cretaceous mantle activity, and have been the main cause of the oceanic crust's thickening in the interior of the Caribbean plate. At the same time, this thickening of the oceanic plate explains the existence of a Mohorovičić discontinuity, with an average depth greater than other regions of the planet, with slight irregularities related to highs of the ocean floor (Nicaragua and Beata Crests, Aves High) but not similar to the magnitude of lateral variations revealed by the Curie isotherm map.

  19. Shifting baselines and the extinction of the Caribbean monk seal.

    2013-10-01

    The recent extinction of the Caribbean monk seal Monachus tropicalis has been considered an example of a human-caused extinction in the marine environment, and this species was considered a driver of the changes that have occurred in the structure of Caribbean coral reef ecosystems since colonial times. I searched archaeological records, historical data, and geographic names (used as a proxy of the presence of seals) and evaluated the use and quality of these data to conclude that since prehistoric times the Caribbean monk seal was always rare and vulnerable to human predation. This finding supports the hypothesis that in AD 1500, the Caribbean monk seal persisted as a small fragmented population in which individuals were confined to small keys, banks, or isolated islands in the Gulf of Mexico and the Caribbean Sea. This hypothesis is contrary to the assumption that the species was widespread and abundant historically. The theory that the main driver of monk seal extinction was harvesting for its oil for use in the sugar cane industry of Jamaica during the 18th century is based primarily on anecdotal information and is overemphasized in the literature. An analysis of reported human encounters with this species indicates monk seal harvest was an occasional activity, rather than an ongoing enterprise. Nevertheless, given the rarity of this species and its restricted distribution, even small levels of hunting or specimen collecting must have contributed to its extinction, which was confirmed in the mid-20th century. Some sources had been overlooked or only partially reviewed, others misinterpreted, and a considerable amount of anecdotal information had been uncritically used. Critical examination of archaeological and historical records is required to infer accurate estimations of the historical abundance of a species. In reconstructing the past to address the shifting baseline syndrome, it is important to avoid selecting evidence to confirm modern prejudices. PMID

    This paper provides an analysis of the distribution patterns of marine biodiversity and summarizes the major activities of the Census of Marine Life program in the Caribbean region. The coastal Caribbean region is a large marine ecosystem (LME) characterized by coral reefs, mangroves, and seagrasses, but including other environments, such as sandy beaches and rocky shores. These tropical ecosystems incorporate a high diversity of associated flora and fauna, and the nations that border the Caribbean collectively encompass a major global marine biodiversity hot spot. We analyze the state of knowledge of marine biodiversity based on the geographic distribution of georeferenced species records and regional taxonomic lists. A total of 12,046 marine species are reported in this paper for the Caribbean region. These include representatives from 31 animal phyla, two plant phyla, one group of Chromista, and three groups of Protoctista. Sampling effort has been greatest in shallow, nearshore waters, where there is relatively good coverage of species records; offshore and deep environments have been less studied. Additionally, we found that the currently accepted classification of marine ecoregions of the Caribbean did not apply for the benthic distributions of five relatively well known taxonomic groups. Coastal species richness tends to concentrate along the Antillean arc (Cuba to the southernmost Antilles) and the northern coast of South America (Venezuela – Colombia), while no pattern can be observed in the deep sea with the available data. Several factors make it impossible to determine the extent to which these distribution patterns accurately reflect the true situation for marine biodiversity in general: (1) highly localized concentrations of collecting effort and a lack of collecting in many areas and ecosystems, (2) high variability among collecting methods, (3) limited taxonomic expertise for many groups, and (4) differing levels of activity in the study of

  1. Seafaring Capabilities in the Pre-Columbian Caribbean

    Fitzpatrick, Scott M.

    2013-06-01

    At historic contact Europeans remarked on the skill and proficiency of native Caribbean Amerindians to build and travel in dugout canoes. While archaeological examples of these have been recorded throughout the circum-Caribbean, very few exist in the Antillean chain of islands. Despite this deficiency, indirect evidence of seafaring along with archaeological data has suggested to many that the sea was an artery that linked prehistoric communities together between islands and continents through exchange networks and settlement `lifelines'. It is clear that frequent interaction was taking place prehistorically in the region, but examination of seafaring capabilities and the general lack of hard archaeological evidence for contacts in many places suggest this was largely restricted to interaction between the islands and with South America. The fact remains that seafaring in the Caribbean, as one of the smaller aquatic realms inhabited by humans in the past, was highly influenced and largely structured by oceanographic and anemological effects that limited the development of various watercraft designs and navigational techniques which are seen in many of the other world's seas and oceans. In this paper I: (1) synthesize what is currently known about the antiquity and development of early seafaring in the Caribbean; (2) highlight debates about the level of technologies found in the region; (3) discuss how environmental conditions likely influenced seafaring capabilities and settlement patterns; (4) outline the possible evidence for connections between the different surrounding mainland areas; and (5) provide a comparison with seafaring technologies found in the Pacific to help contextualize the Caribbean into the broader context of global seafaring.

  3. Seismic imaging of the southeast Caribbean plate margin

    Bravo, Tammy Katherine

    The SE Caribbean Margin Continental Dynamics Project is a multi-disciplinary investigation of the large scale structure and tectonic framework of the northern boundary of South America. To study the deeper mantle and lithospheric structure, we deployed and maintained an 83 station, broadband array in Venezuela with instruments spanning from the craton south of the Orinoco to the oceanic crust of the Caribbean plate. The first contribution of this work is documentation of the deployment and maintenance of the array. I applied body wave tomography to the data collected during the 18 month deployment. The body wave tomography results produce new constraints on the nature of the Caribbean-South American plate boundary, and provide a new tectonic interpretation of the plate relationships at depth. The tomography results indicate the subducting Atlantic plate descends into the mantle at a relatively low angle parallel to the strike-slip plate boundary in northern Venezuela. This contrasts with previous tomography models for this region that suggest the plate steepens to near vertical dip at its southern edge. I argue the previous results are likely a misinterpretation of artifacts from poorer coverage than what was available for this study. The main arguments for this claim are based on the geometry from a three-dimension plate model constructed for the entire Caribbean. Steepening of the plate implied by previous results requires a sharp reversal in the curvature of the subducting slab that is difficult to reconcile with the constraints imposed by active volcanoes in the Antilles Arc. Finally, a related three-dimensional model was developed for the complex southwestern corner of the Caribbean plate. While this area in Western Venezuela is not well resolved by our data, we can offer some constraints on the structure and explain deep earthquakes under Maracaibo.

    The Caribbean plate project is designed to improve current understanding of geological resources and geological hazards within the Caribbean region. Models of mineral occurrence and genesis (including energy resources) on a regional scale, which contribute to nonrenewable resource investigations. Models of lithospheric stress and strain on a regional scale, which contribute to forecasting geological hazards such as earthquakes and major volcanic eruptions are developed. Geological information is synthesize, and research tools provided by space technology the study of the Earth's crust are used. The project was organized in a thematic fashion, to focus on specific geological aspects of the Caribbean plate which are considered to be key factors in developing the types of models described. The project adopts a synoptic perspective in seeking to characterize the three dimensional structure, composition, state of stress, and evolution of the entire Caribbean plate. Geological information derived from analysis of space acquired data is combined with information provided by conventional methods to obtain insight into the structure, composition, and evolution of the Earth's crust. In addition, very long baseline interferometry and laser ranging techniques, which are also based upon the use of space technology, obtain information concerning crustal motion that, in turn, provides insight into the distribution and localization of crustal stress.

  6. Anaglyph with Landsat Virgin Islands, Caribbean

    St. Thomas, St. John, Tortola, and Virgin Gorda are the four main islands (lower left to upper right) of this map-view anaglyph of the U.S. Virgin Islands and British Virgin Islands, along the northeast perimeter of the Caribbean Sea. For this view, a nearly cloud-free Landsat image was draped over elevation data from the Shuttle Radar Topography Mission (SRTM), and shading derived from the SRTM data was added to enhance the topographic expression. Coral reefs fringe the islands in many locations and appear as bright patterns in near-shore waters. Tropical vegetation appears fairly dark with smooth tones, as compared to the brighter speckled patterns of towns and other developments.

    As in much of the world, topography is the primary factor in the pattern of land use development in the Virgin Islands. Topography across most of the islands is quite rugged, and although the steep slopes create a scenic setting, they crowd most development into the small areas of low relief terrain, generally along the shoreline. The topographic pattern also affects water supply, wastewater disposal, landfill locations, road construction, and most other features of the development infrastructure. Topography also defines the natural drainage pattern, which is the major consideration in anticipating tropical storm water runoff dangers, as well as the dangers of heightened sediment impacts upon the adjacent coral reefs.

    Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and substantially helps in analyzing the large and growing Landsat image archive.

    Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000. The mission used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar that flew twice on the Space Shuttle

    This study examined differences in religious participation and spirituality among African Americans, Caribbean Blacks (Black Caribbeans) and non-Hispanic Whites. Data are taken from the National Survey of American Life, a nationally representative study of African Americans, Black Caribbeans and non-Hispanic Whites. Selected measures of organizational, nonorganizational and subjective religious participation were examined. African American and Caribbean Blacks were largely similar in their reports of religious involvement; both groups generally indicated higher levels of religious participation than non-Hispanic Whites. African Americans were more likely than Black Caribbeans to be official members of their places of worship, engage in activities (choirs, church clubs) at their place of worship and request prayer from others. Black Caribbeans reported reading religious materials more frequently than African Americans. The discussion notes the importance of examining ethnic differences within the black American population of the United States. PMID:20975850

    For market studies of renewable energy and conservation equipment, Costa Rica was selected as the most favorable Central American country and representative of the rest. The Dominican Republic, Jamaica, Barbados, and Antigua were selected as representative of the Caribbean islands, from the largest to one of the smallest. Best markets in Costa Rica are judged to be micro and mini hydroelectric systems, heat pumps for large hot water users, photovoltaic systems for low-power remote devices, small distilleries for producing alcohol from sugar cane, solar dryers for bagasse, and energy conservation equipment. Market prospects for the Caribbean islands are very good, including micro and mini hydroelectric systems for those countries with water resources, solar drying of bagasse, solar water heaters, solar ponds/solar thermal systems for electric power or heat processes, wind-electric systems for utility grids and farms, photovoltaics for small power uses, and energy conservation equipment.

    In the last two decades, the Latin America/Carribean region has become increasingly dependent on electricity to meet growing demands for energy. Hydropower is the prevailing source for meeting this need. Hydroelectric generation increased at an annual average rate of nearly 9% between 1971 and 1989. HYdro now provides more than two-thirds of total electric power generated in Latin America and the Caribbean. The only other predominant source used for electric generation is fossil fuels. In this region there are several trends developing. They include: developing more small hydro facilities, opportunities for sharing water resources, an interest in changing the approach to water use regulation, and possibilities for more participation by the private sector. Overall, hydro appears to have a favorable competitive position in the power industry in the Latin America/Caribbean region.

    This is the first report of a ciliate of the genus Halofolliculina infecting hard coral species of six families (Acroporidae, Agaricidae, Astrocoeniidae, Faviidae, Meandrinidae and Poritidae) and milleporids in the Caribbean. Surveys conducted during 2004 2005 in Venezuela, Panama and México confirmed that this ciliate affects up to 25 scleractinian species. The prevalence of this ciliate at the coral community level was variable across sites, being most commonly found at Los Roques, Venezuela, and at Bocas del Toro, Panama (prevalence 0.2 2.5%), but rarely observed in the Mexican Caribbean. Ciliates were more prevalent within populations of acroporids ( Acropora palmata, Acropora cervicornis and Acropora prolifera) in Los Roques. Recent observations also corroborate the presence of these ciliates in Curacao and Puerto Rico. Our observations indicate that ciliates affecting corals have a wider distribution than previously thought, and are no longer exclusively found in the Indo-Pacific and Red Sea.

    Although environmental tributyltin (TBT) contamination is considered a solved problem, imposex occurrence in Plicopurpura patula as well as butyltins (BTs) contamination in sediments and tissues were detected along 700 km of the Caribbean coastal shore. Areas under the influence of five main ports of Venezuela were covered, as well as large marinas and sites located away from expected sources. Marinas were the most contaminated areas, whilst imposex incidence and TBT levels were relatively low in areas nearby commercial harbors. Thus, it is evident that marinas have become the main source of fresh TBT to the region. This might explain why imposex incidence seems to be widely distributed along the Venezuelan coast, since leisure boats are circulating along the whole coastal region. In fact, this could be the pattern for other areas of the Caribbean Sea. PMID:25155631

    The impacts of drought in the Caribbean have not been as dramatic as in some other parts of world, but it is not exempt from the experiences of drought. As a result of the effects of a prolonged drought in 2009/2010, the agenda for the 21st Inter-Sessional Meeting of the Caribbean Community (CARICOM) paid particular attention to the issue of drought. This paper reviews the management framework for responding to drought disasters in five CARICOM countries. The paper also reports on some of the effects of the 2009/2010 drought with particular reference to Grenada and the Grenadines. During the drought in these islands there were numerous bush fires with devastating effects on agriculture, severe water shortages that impacted on the tourism industry and other social effects. It is evident that there was inadequate preparation for the event. Greater planning and investment are therefore required to reduce future impacts. PMID:25754334

Health and social service professionals, governmental organizations, elderly persons, and others from across the English-speaking Caribbean countries developed the Pillars framework to address the growing elderly population and with an aim to increase the number of healthy and active years of life. The Pillars framework consists of four interrelated pillars organized across multiple sectors of society: primary care with care management; integrated services coordination; population-based health promotion and disease prevention; and planning and accountability. Pillars is enabled by an envisioned integrated system of information technology that will increase community-based services delivery, interprofessional communication and coordination, and will aggregate data with all identifiers removed for surveillance, planning, forecasting, policy making, evaluation, and research.

  14. Structural and geophysical interpretation of Roatan Island, Honduras, Western Caribbean

    NASA Astrophysics Data System (ADS)

    Sutton, Daniel Scott

    Roatan Island is the largest of the Bay Islands of Honduras. These islands form an emergent crest off the Caribbean coast of Honduras called the Bonacca Ridge. The Bartlett Trough to the north and subsequent Bonacca Ridge were likely formed due to the transform fault system of the Motagua-Swan Islands Fault System. This fault system forms the tectonic plate boundary between the North American and Caribbean plates. Although the timing and kinematics are poorly constrained, the Bay Islands and the Bonacca Ridge were likely uplifted due to transpression along this left-lateral strike-slip system. With limited regional exposures along the adjacent tectonic boundary, this study aimed to present a structural interpretation for Roatan. This new interpretation is further explained through regional considerations for a suggested geologic history of the northwestern Caribbean. In order to better constrain the kinematics of uplift and exhumation of Roatan Island, structural, gravity, and magnetic surveys were conducted. Principal attention was directed to the structural relationship between the geologic units and their relationship to one another through deformation. Resulting geologic cross-sections from this study present the metamorphic basement exposed throughout the island to be in a normal structural order consisting of biotite schist and gneiss, with overlying units of chlorite schist, carbonate, and conglomerate. These units have relatively concordant strike and dip measurements, consistent with resultant magnetic survey readings. Additionally, large and irregular bodies of amphibolite and serpentinite throughout the island are interpreted to have been emplaced as mafic and ultra-mafic intrusions in weakness zones along Early Paleogene transform system fault planes. The interpretation and suggested geologic history from this study demonstrate the importance of transpressive tectonics both local to Roatan and regionally throughout geologic history.

The authors' survey in 1989 revealed that there has been no apparent decline since the last study in 1977. However, there is no evidence for population growth either and as the Belize economy develops threats from fisheries, human pressure and declining habitat quality will increase. Recommendations are made to ensure that Belize safeguards its manatee populations.

    We report new examples of Cenozoic cold-seep communities from Colombia, Cuba, the Dominican Republic, Trinidad, and Venezuela, and attempt to improve the stratigraphic dating of Cenozoic Caribbean seep communities using strontium isotope stratigraphy. Two seep faunas are distinguished in Barbados: the late Eocene mudstone-hosted ‘Joes River fauna’ consists mainly of large lucinid bivalves and tall abyssochrysoid gastropods, and the early Miocene carbonate-hosted ‘Bath Cliffs fauna’ containing the vesicomyid Pleurophopsis, the mytilid Bathymodiolus and small gastropods. Two new Oligocene seep communities from the Sinú River basin in Colombia consist of lucinid bivalves including Elongatolucina, thyasirid and solemyid bivalves, and Pleurophopsis. A new early Miocene seep community from Cuba includes Pleurophopsis and the large lucinid Meganodontia. Strontium isotope stratigraphy suggests an Eocene age for the Cuban Elmira asphalt mine seep community, making it the oldest in the Caribbean region. A new basal Pliocene seep fauna from the Dominican Republic is characterized by the large lucinid Anodontia (Pegophysema). In Trinidad we distinguish two types of seep faunas: the mudstone-hosted Godineau River fauna consisting mainly of lucinid bivalves, and the limestone-hosted Freeman’s Bay fauna consisting chiefly of Pleurophopsis, Bathymodiolus, and small gastropods; they are all dated as late Miocene. Four new seep communities of Oligocene to Miocene age are reported from Venezuela. They consist mainly of large globular lucinid bivalves including Meganodontia, and moderately sized vesicomyid bivalves. After the late Miocene many large and typical ‘Cenozoic’ lucinid genera disappeared from the Caribbean seeps and are today known only from the central Indo-Pacific Ocean.

    The non-native seagrass Halophila stipulacea has spread rapidly throughout the Caribbean Sea (Willette et al. 2014); without additional research, the ecological ramifications of this invasion are difficult to predict. Biodiversity, connectivity of marine ecosystems, and recovery of degraded coral reefs could all be affected. The invasive seagrass, native to the Red Sea and Indian Ocean, has taken over sand bottoms and intermixed with or replaced native seagrasses, including Thalassia testudinum, Syringodium filiforme, and Halodule wrightii.

    We report new examples of Cenozoic cold-seep communities from Colombia, Cuba, the Dominican Republic, Trinidad, and Venezuela, and attempt to improve the stratigraphic dating of Cenozoic Caribbean seep communities using strontium isotope stratigraphy. Two seep faunas are distinguished in Barbados: the late Eocene mudstone-hosted 'Joes River fauna' consists mainly of large lucinid bivalves and tall abyssochrysoid gastropods, and the early Miocene carbonate-hosted 'Bath Cliffs fauna' containing the vesicomyid Pleurophopsis, the mytilid Bathymodiolus and small gastropods. Two new Oligocene seep communities from the Sinú River basin in Colombia consist of lucinid bivalves including Elongatolucina, thyasirid and solemyid bivalves, and Pleurophopsis. A new early Miocene seep community from Cuba includes Pleurophopsis and the large lucinid Meganodontia. Strontium isotope stratigraphy suggests an Eocene age for the Cuban Elmira asphalt mine seep community, making it the oldest in the Caribbean region. A new basal Pliocene seep fauna from the Dominican Republic is characterized by the large lucinid Anodontia (Pegophysema). In Trinidad we distinguish two types of seep faunas: the mudstone-hosted Godineau River fauna consisting mainly of lucinid bivalves, and the limestone-hosted Freeman's Bay fauna consisting chiefly of Pleurophopsis, Bathymodiolus, and small gastropods; they are all dated as late Miocene. Four new seep communities of Oligocene to Miocene age are reported from Venezuela. They consist mainly of large globular lucinid bivalves including Meganodontia, and moderately sized vesicomyid bivalves. After the late Miocene many large and typical 'Cenozoic' lucinid genera disappeared from the Caribbean seeps and are today known only from the central Indo-Pacific Ocean. We speculate that the increasingly oligotrophic conditions in the Caribbean Sea after the closure of the Isthmus of Panama in the Pliocene may have been unfavorable for such large lucinids because they

    Paleontologists typically treat major episodes of extinction as single and distinct events in which a major environmental perturbation results in a synchronous evolutionary response. Alternatively, the causes of biotic change may be multifaceted and extinction may lag behind the changes ultimately responsible because of nonlinear ecological dynamics. We examined these alternatives for the major episode of Caribbean extinction 2 million years ago (Ma). Isolation of the Caribbean from the Eastern Pacific by uplift of the Panamanian Isthmus was associated with synchronous changes in Caribbean near shore environments and community composition between 4.25 and 3.45 Ma. Seasonal fluctuations in Caribbean seawater temperature decreased 3-fold, carbonate deposition increased, and there was a striking, albeit patchy, shift in dominance of benthic ecosystems from heterotrophic mollusks to mixotrophic reef corals and calcareous algae. All of these changes correspond well with a simple model of decreased upwelling and collapse in planktonic productivity associated with the final stages of the closure of the isthmian barrier. However, extinction rates of mollusks and corals did not increase until 3–2 Ma and sharply peaked between 2 and 1 Ma, even though extinction overwhelmingly affected taxa commonly associated with high productivity. This time lag suggests that something other than environmental change per se was involved in extinction that does not occur as a single event. Understanding cause and effect will require more taxonomically refined analysis of the changing abundance and distribution patterns of different ecological guilds in the 2 million years leading up to the relatively sudden peak in extinction.

    Objective: To explore the emotional intelligence (EI) in medical students in a Caribbean medical school and investigate its association with gender, age, year of study and ethnicity. Design and Methods: A cross-sectional design using convenient sampling of 304 years two to five undergraduate medical students at the School of Medicine, The University of the West Indies (UWI), St Augustine campus, was conducted. The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT-V2.0) was administered to test four branches of EI: perceiving emotions, facilitating thought, understanding emotions and managing emotions. Data were analysed using SPSS version 19. T-test, analysis of variance (ANOVA) and r (product moment correlation) were calculated to establish the effects of selected variables (gender, age, year of study and ethnicity) on total and sub-scales EI scores and tested against 0.05 and 0.01 significance levels. Results: The total mean score for EI fell within the average according to MSCEIT standards. Gender analysis showed significantly higher scores for males and for younger age groups (< 25 years). Year of study and ethnicity did not yield any significant effect. Conclusions: These findings of higher EI scores in males and younger students are unusual, given the well-publicized stereotype of the Caribbean male and the perception that advancing age brings maturity and emotional stability. It would be valuable to widen this study by including other UWI campuses and offshore medical schools in the Caribbean. This preliminary study examined a sample of medical students from a well-established Caribbean medical school. Since EI is considered to be important in the assessment and training of medical undergraduates, consideration should be given to introducing interventions aimed at increasing EI. PMID:25303251

    The Caribbean basin is home to some of the most complex interactions in recent history among previously diverged human populations. Here, we investigate the population genetic history of this region by characterizing patterns of genome-wide variation among 330 individuals from three of the Greater Antilles (Cuba, Puerto Rico, Hispaniola), two mainland (Honduras, Colombia), and three Native South American (Yukpa, Bari, and Warao) populations. We combine these data with a unique database of genomic variation in over 3,000 individuals from diverse European, African, and Native American populations. We use local ancestry inference and tract length distributions to test different demographic scenarios for the pre- and post-colonial history of the region. We develop a novel ancestry-specific PCA (ASPCA) method to reconstruct the sub-continental origin of Native American, European, and African haplotypes from admixed genomes. We find that the most likely source of the indigenous ancestry in Caribbean islanders is a Native South American component shared among inland Amazonian tribes, Central America, and the Yucatan peninsula, suggesting extensive gene flow across the Caribbean in pre-Columbian times. We find evidence of two pulses of African migration. The first pulse--which today is reflected by shorter, older ancestry tracts--consists of a genetic component more similar to coastal West African regions involved in early stages of the trans-Atlantic slave trade. The second pulse--reflected by longer, younger tracts--is more similar to present-day West-Central African populations, supporting historical records of later transatlantic deportation. Surprisingly, we also identify a Latino-specific European component that has significantly diverged from its parental Iberian source populations, presumably as a result of small European founder population size. We demonstrate that the ancestral components in admixed genomes can be traced back to distinct sub-continental source

    The authors propose a three-phase geologic-kinematic model for the evolution of the Gulf of Mexico/Caribbean region starting with a detailed Late Paleozoic (Alleghenian) plate reconstruction and using a revised relative-motion history for North America (NOAM) and South American (SOAM). The completely closed initial reconstruction incorporates the effects of Jurassic syn-rift crustal extension, an improved Equatorial Atlantic fit, and the post-rift accretion and deformation in northwestern South America. The Yucatan block and western Bahamas continental basement occupied the area of the present Gulf of Mexico. The three phases of evolution are: MIDDLE JURASSIC-CHAMPANIAN; SOAM migrated east-southeast from NOAM, and the Yucatan block rotated 43/sup 0/CCW about a pole in northern Florida reaching its present position by the Berriasian. Carbonate shelves formed along the rifted margins of the Gulf of Mexico and proto-Caribbean. Early Cretaceous crust of the Caribbean Plate (CARIB) formed in the Pacific Basin and was intruded by medial Cretaceous basalts (B'') somewhere to the west of South America. CARIB partially collided with southern Yucatan and northwest SOAM in the Late Cretaceous, and with the Bahamas in the late Paleocene-Middle Eocene. POST-MIDDLE EOCENE: Minor west-northwest NOAM-SOAM convergence occurred along preexisting Atlantic fracture zones. CARIB has migrated eastward by 1200 km, subducting proto-Caribbean crust and forming the Lesser Antilles arc. The original Greater Antilles-Aves Ridge arc has been dissected by anastomosing transforms connecting the Middle American and Lesser Antilles trenches.

    Coral species are difficult to discern because of their morphological plasticity, long generation times, and slow rates of mitochondrial DNA evolution. Among Caribbean representatives of the genus Porites are three named species ( P. divaricata, P. furcata, and P. porites) with branching colony morphologies whose validity as genetically isolated species has been debated. We present sequence data from the mitochondrial control region, nuclear ITS, and nine single-copy nuclear loci for the Caribbean Porites and a related eastern Pacific species. mtDNA sequences were nearly invariant among the three branching species and their crustose sister P. branneri, and ITS sequences from these four were intermingled. An information theoretic analysis provided no support for upholding the three named Caribbean branching species. Both a clustering analysis and an analysis of molecular variance showed that sequence variation from the three branching forms is partitioned more by geography than by taxonomy. Multi-locus coalescent phylogenetic analysis provided a calibrated estimate for the nuclear DNA substitution rate (0.14 % Ma-1) close to that for other corals. Because no generalities have emerged from genetic investigations of the validity of morphologically defined coral species, the use of single-copy nuclear data is likely to be important in testing problematic species designations.

    Coral growth rates are highly dependent on environmental variables such as sea surface temperature and solar irradiance. Multi-decadal variability in coral growth rates has been documented throughout the Caribbean over the past 150-200 years, and linked to variations in Atlantic sea surface temperatures. Multi-decadal variability in sea surface temperatures in the North Atlantic, in turn, has been linked to volcanic and anthropogenic aerosol forcing. Here, we examine the drivers of changes in coral growth rates in the western Caribbean between 1880 and 2000, using previously published coral growth chronologies from two sites in the region, and a numerical model. Changes in coral growth rates over this period coincided with variations in sea surface temperature and incoming short-wave radiation. Our model simulations show that variations in the concentration of anthropogenic aerosols caused variations in sea surface temperature and incoming radiation in the second half of the twentieth century. Before this, variations in volcanic aerosols may have played a more important role. With the exception of extreme mass bleaching events, we suggest that neither climate change from greenhouse-gas emissions nor ocean acidification is necessarily the driver of multi-decadal variations in growth rates at some Caribbean locations. Rather, the cause may be regional climate change due to volcanic and anthropogenic aerosol emissions.

  10. Renewable power production in a Pan-Caribbean energy grid

    Miller, David

    The Small Island Developing States of the Caribbean are victims of geography and geopolitics. Lacking access to large fossil fuel reserves, they are forced to import fuel at prices they have no control over. Renewable energy resources, particularly wind, have the potential to help break the Caribbean dependency on fossil fuels and allow for increased development at the same time. Working from a sustainable development point of view, this project discusses the history of the area, the theoretical background for the idea of large scale renewable power production, the regional initiatives already in place that address both the cost of fossil fuels and the policy hurdles that need to be overcome to assist the region in gaining energy independence. Haiti is highlighted as a special case in the region and the potential use of several renewable resources are discussed, along with a potential business model based on the idea of the Internet. Power storage is covered, specifically the potential of battery operated vehicles to have a positive impact on the Caribbean region and other developing states. The role of government regulation and policy comes into play next, followed by a discussion on the need for developed states to change patterns of behavior in order to achieve sustainability. Finally, nuclear power and liquefied natural gas are reviewed and rejected as power options for the region.

    Our aim is to provide a complete key and guide to the species of black corals from the Caribbean reefs at depths shallower than about 100 m. The key to the species is mostly based on colonial features that are recognized in the field, although some closely related species can only be differentiated by microscopic skeletal features. Each species is illustrated with one or more photos showing the size and shape of the colony; many photos were taken in the natural environment to facilitate underwater identification. Additionally, a short description is provided of each species and their microscopic diagnostic characters are illustrated with the aid of the Scanning Electron Microscope (SEM). Fifteen black coral species are found in relatively shallow-water in the Caribbean, Gulf of Mexico, and other parts of the tropical western Atlantic; these belong to the families Myriopathidae [Tanacetipathes hirta (Gray), T. tanacetum (Pourtales), T. barbadensis (Brook), T. thamnea (Warner), and Plumapathes pennacea (Pallas)]; Antipathidae [Antipathes lenta Pourtales, A. rubusifonnis Warner and Opresko, A. furcata Gray, A. umbratica Opresko, A. atlantica Gray, A. gracilis Gray, A. caribbeana Opresko, Stichopathes lutkeni Brook, and S. accidentalis (Gray)]; and Aphanipathidae [Rhipidipathes colombiana (Opresko and Sinchez)]. We hope that this guide will facilitate research on black corals on Caribbean reefs, where population surveys are urgently needed to evaluate or modify conservation policies.

    The purpose of preparing this annotated bibliography was to compile information on coal localities for the Caribbean region used for preparation of a coal map of the region. Also, it serves as a brief reference list of publications for future coal studies in the Caribbean region. It is in no way an exhaustive study or complete listing of coal literature for the Caribbean. All the material was gathered from published literature with the exception of information from Cuba which was supplied from a study by Gordon Wood of the US Geological Survey, Branch of Coal Resources. Following the classification system of the US Geological Survey (Wood and others, 1983), the term coal resources has been used in this report for reference to general estimates of coal quantities even though authors of the material being annotated may have used the term coal reserves in a similar denotation. The literature ranges from 1857 to 1981. The countries listed include Colombia, Mexico, Venezuela, Cuba, the Dominican Republic, Haiti, Jamaica, Puerto Rico, and the countries of Central America.

    1981-09-01

    Hurricanes increase the risk of oil spills in the Caribbean region, a situation which the United Nations and affected islands recognize as requiring cooperative efforts to prevent and control. As shipping activity increases in the Caribbean, the threat is intensified by the small size and poverty of the area's islands, which depend heavily on tourist and fishing industries. The annual 250 million tons of crude oil shipped to or through the Caribbean can be expected to average 21 spills of 1000 tons within 50 miles of land and pose serious ecological and economic threats. A contingency plan based on cooperation and shared resources to deal with spills would not be expensive because the liability laws and compensation rights are clearly defined. The technologies available to combat oil spills range from biological agents to sweeping equipment. Response can be prompt, but the political and economic aspects are more delicate. A regional plan formulated by the islands and countries involved still needs to have formal intergovernmental agreements signed. (DCK)

    Lobster fishing (targeting the spiny lobster Panulirus argus) is an important economic activity throughout the Wider Caribbean Region both as a source of income and employment for the local population as well as foreign exchange for national governments. Due to the high unit prices of the product, international lobster trade provides a way to improve the livelihoods of fisheries-dependent populations. The specie harvested is identical throughout the region and end market prices are roughly similar. In this paper we wish to investigate to which extent lobster fishers' job satisfaction differs in three countries in the Caribbean and how these differences can be explained by looking at the national governance arrangements.

    In the broad context of investigating the relationship between deep structure & processes and surface expressions, we study the Caribbean plate and underlying mantle. We investigate whether predictions of mantle structure from tectonic reconstructions are in agreement with a detailed tomographic image of seismic P-wave velocity structure under the Caribbean region. In the upper mantle, positive seismic anomalies are imaged under the Lesser Antilles and Puerto Rico. These anomalies are interpreted as remnants of Atlantic lithosphere subduction and confirm tectonic reconstructions that suggest at least 1100 km of convergence at the Lesser Antilles island arc during the past ~45 Myr. The imaged Lesser-Antilles slab consists of a northern and southern anomaly, separated by a low velocity anomaly across most of the upper mantle, which we interpret as the subducted North-South America plate boundary. The southern edge of the imaged Lesser Antilles slab agrees with vertical tearing of South America lithosphere. The northern Lesser Antilles slab is continuous with the Puerto Rico slab along the northeastern plate boundary. This results in an amphitheater-shaped slab and it is interpreted as westward subducting North America lithosphere that remained attached to the surface along the northern boundary. At the Muertos Trough, however, material is imaged until a depth of only 100 km, suggesting a small amount of subduction. The location and length of the imaged South Caribbean slab agrees with proposed subduction of Caribbean lithosphere under the northern South America plate. An anomaly related to proposed Oligocene subduction at the Nicaragua rise is absent in the tomographic model. Beneath Panama, a subduction window exists across the upper mantle, which is related to the cessation of subduction of the Nazca plate under Panama since 9.5 Ma and possibly the preceding subduction of the extinct Cocos-Nazca spreading center.

    Background The Caribbean region, like other developing regions of the world, faces significant challenges in conducting research, especially in the context of limited resource capacities and capabilities. Further, due to its diverse and multiple island states, research capacity is scattered and unevenly spread within the region. The Caribbean EcoHealth Programme (CEHP) is a research program that is structured to improve the capacity and capability of health professionals in the Caribbean region to respond in integrative and innovative ways to on-going and emerging environmental health challenges by means of multi-sectoral interventions. Methods Core parts of the CEHP’s mission are to (1) conduct collaborative research in areas that the region has identified as critical; (2) build and strengthening integrated approaches to research; and (3) develop and enhance basic research capacity within the Caribbean region. Fundamental to the success of the CEHP’s human and resource development mission has been its use of the Atlantis Mobile Laboratory (AML). The AML has allowed the CEHP program to move throughout the Caribbean and be able to respond to calls for specific research and capacity building opportunities. Results The CEHP’s five main research projects have generated the following results: (1) the Persistent Organic Pollutants (POPs) study has evaluated human exposures to POPs, heavy metals, pesticides, and zoonotic infections; (2) the Burden of Illness (BOI) studies have developed protocols for the testing of foodborne microorganisms, strengthen laboratory analytical capabilities, and determined the prevalence and incidence of food-borne illness; (3) the Rainwater Harvesting (RWH) study has evaluated the microbial and chemical quality of rainwater harvesting systems; (4) the Ecotoxicology Water (ETW) studies have provided much needed data on the quality of recreational and drinking water supplies, and (5) the Food Safety Training Program has developed Diploma

    Mineral dust is an important component of the atmosphere and the climate system since mineral dust acts as cloud condensation nuclei (CCN) as well as ice nuclei (IN) and contributes significantly to the global annual particle emissions by mass. Every year, huge amounts of Saharan mineral dust is transported westward across the Atlantic Ocean into the Caribbean. During transport, the chemical and microphysical properties of the mineral dust may be modified thereby changing the CCN properties of the dust aerosol. During the Saharan Aerosol Long-range Transport and Aerosol-Cloud-Interaction Experiment (SALTRACE: http://www.pa.op.dlr.de/saltrace) in June/July 2013, CCN measurements were performed on the DLR Falcon research aircraft with a dual column Cloud Condensation Nuclei Counter (CCNC) first at Cape Verde then at the Caribbean. The CCNC provides information about concentration of CCN at two different supersaturations at the same time. For SALTRACE, one column of the CCNC was set to 0.2% supersaturation, whereas the second column was operated in scanning mode at different supersaturations between 0.1 and 0.5%. Additional CCN measurements by a ground-based single column CCNC were performed at Ragged Point, Barbados. During SALTRACE five mineral dust outbreaks were investigated. The CCN measurements in the Caribbean showed three layers with different CCN characteristics during these outbreaks. In the upper part (2.5 to 4.5 km) of the Saharan Air Layer (SAL) in the Caribbean the aerosol properties are similar to the ones measured in the dust layer over Cape Verde and the CCNC measurements show low CCN concentrations and little activated fraction. In contrast, a higher variability was detected in the lower part (0.7 to 2.5 km) of the SAL. Within this layer a much higher CCN activation leads to a larger CCN concentration and cumulus clouds were frequently observed. Below 0.7 km also a high variability in activated fraction was observed, but CCN concentration was lower

  19. Eradication of the tropical bont tick in the Caribbean: is the Caribbean amblyomma program in a crisis?

    The progress and problems in the Caribbean Amblyomma Program (CAP) are reviewed since its inception in 1995. During 1998, there were funding and administrative management problems. USDA resolved the acute funding crisis, and after three years of negotiation, the CAP has now secured an additional euro 1.5 million from the European Community. Changes in administration in 1998 included the withdrawal of IICA from the program, and the transition during the decentralization of administrative and financial management from FAO headquarters to the Regional Office for Latin America and the Caribbean, based in Chile. A general overview of technical progress and one case study, St. Kitts, is presented. One major concern that emerged during 2000 is that the elimination of the small remaining tropical bont tick (TBT) "hot spots" in both St. Kitts and St. Lucia remained elusive. Why is this so? Egrets? Alternative residual hosts? Or is it fatigue in both technical and administrative management functions? Of even greater concern is the finding of two, apparently new, foci in St. Croix (USVI) in the north and St. Vincent in the south. A critical overview of the program has identified one major remaining constraint-an appropriate management support function at both regional and, in some countries, at the national level. A proposal for a revised management strategy, coupled with the identification of a future strategy to succeed the CAP, namely a Caribbean Animal Resources Management (CARM) Program. PMID:12381609

  20. Comparative phylogeography of Atlantic reef fishes indicates both origin and accumulation of diversity in the Caribbean

    PubMed Central

    2008-01-01

    Background Two processes may contribute to the formation of global centers of biodiversity: elevated local speciation rates (the center of origin hypothesis), and greater accumulation of species formed elsewhere (the center of accumulation hypothesis). The relative importance of these processes has long intrigued marine biogeographers but rarely has been tested. Results To examine how origin and accumulation affected the Greater Caribbean center of diversity, we conducted a range-wide survey of mtDNA cytochrome b in the widespread Atlantic reef damselfish Chromis multilineata (N = 183) that included 10 locations in all four tropical Atlantic biogeographic provinces: the Greater Caribbean, Brazil, the mid-Atlantic ridge, and the tropical eastern Atlantic. We analyzed this data and re-evaluated published genetic data from other reef fish taxa (wrasses and parrotfishes) to resolve the origin and dispersal of mtDNA lineages. Parsimony networks, mismatch distributions and phylogenetic analyses identify the Caribbean population of C. multilineata as the oldest, consistent with the center of origin model for the circum-Atlantic radiation of this species. However, some Caribbean haplotypes in this species were derived from Brazilian lineages, indicating that mtDNA diversity has not only originated but also accumulated in the Greater Caribbean. Data from the wrasses and parrotfishes indicate an origin in the Greater Caribbean in one case, Caribbean origin plus accumulation in another, and accumulation in the remaining two. Conclusion Our analyses indicate that the Greater Caribbean marine biodiversity hotspot did not arise through the action of a single mode of evolutionary change. Reef fish distributions at the boundaries between Caribbean and Brazilian provinces (the SE Caribbean and NE Brazil, respectively) indicate that the microevolutionary patterns we detected in C. multilineata and other reef fishes translate into macroevolutionary processes and that origin and

  11. The Onset of Early Season Rainfall and its Mid-Summer Cessation in the Caribbean.

    NASA Astrophysics Data System (ADS)

    Allen, T. L.; Mapes, B. E.

    2014-12-01

    The annual rainfall cycle for the Caribbean basin reveals a distinct bimodal pattern with peaks during the late spring and late summer months. A relative minimum during the mid-summer, known as the mid-summer drought (MSD) separates the early rainfall season (ERS) from the late rainfall season. Accumulated rainfall totals during the ERS appear as a quasi-stationary rain-belt stretching across the Caribbean from the southwest to the northeast. We place late spring rains in the Caribbean in context of other subtropical convergence zones in order to address the onset and cessation of the ERS while also offering an explanation of a Caribbean rain-belt pattern. Upper tropospheric westerlies, mid-tropospheric positive temperature advection, and moist low level poleward flow are the three primary ingredients that conspire to produce the first peak of the annual bimodal rain signal and the related Caribbean early season rain-belt. The MSD ensues as the primary ingredients weaken across the Caribbean and enhanced rainfall shifts north along the North Atlantic Convergence Zone (NACZ). Seasonal rainfall totals from the ERS through the MSD periods reveal a continuous rain-belt that extends from the Caribbean to the NACZ termed the Caribbean Atlantic Rain-belt (CAR-belt). The Car-belt is present in the long term mean, but has signs of interannual variability.

  9. Bimodal Distribution of Tropical Cyclogenesis in the Caribbean: Characteristics and Environmental Factors.

    Tropical cyclogenesis critically depends on the presence of warm water at the sea surface. For the North Atlantic basin as a whole, the tropical storm season starts in May, peaks in September, and then declines, generally following the seasonal warming and cooling of sea surface temperature. In the Caribbean, in contrast, there is a distinct bimodal distribution in the number of tropical storms formed, with peaks in June and October separated by a significant minimum in July. The timing of the observed minimum in tropical cyclogenesis appears to be related to the strengthening of the easterly trade winds over the Caribbean associated with the onset of the so-called veranillo, or midsummer drought (MSD), previously recognized over south-central Mexico, Central America, and parts of the Caribbean. It appears that the observed minimum in cyclogenesis is caused by a combination of environmental factors related to the strengthening of the easterly trade winds across the Caribbean Basin. The strengthening easterly trade winds and their associated changes in wind stress curl give rise to enhanced upwelling in the southwestern Caribbean. This appears to trigger an enhanced local atmosphere-ocean coupling, giving rise to very unfavorable conditions in several environmental variables including cooler sea surface temperature (SST), higher sea level pressure (SLP), increase in outgoing longwave radiation (OLR), and decrease in precipitable water content (PRW). Moreover, strengthening trade winds result in increases in tropospheric vertical wind shear (VSH). Except for OLR, these environmental variables become least favorable for southwestern Caribbean cyclogenesis in July. In contrast, the transition from weak to intense convective activity in the eastern Pacific results in weaker trade winds in the Caribbean in October. The resulting westerly wind anomalies lead to weakening upwelling, warmer SST, enhanced convection, and moist air coupled with weaker VSH in the southwestern

    Evaporation exceeds precipitation in the tropical Atlantic, resulting in a net freshwater removal across the Central American Isthmus. Because most of the north Atlantic's subtropical gyre water circulates through the Caribbean before flowing north to sub-polar regions via the Gulf Stream, changes in tropical atmospheric circulation have the potential to affect the salinity and density structure of the entire north Atlantic, thereby influencing glacial-interglacial oscillations in North Atlantic Deep Water (NADW) formation. Here, we combine Mg/Ca measurements (a proxy for the temperature of calcification) and δ 18O analyses of shells from the surface-dwelling foraminifera Globigerinoides ruber s.s. (white var.) from the western Caribbean Colombian Basin at ODP Site 999A (2827m; 4cm/ka sed. rate) and VM28-122 (3623m; 4-10cm/ka sed. rate) to produce the first continuous record of western tropical Atlantic δ 18OSEAWATER (δ 18OSW) during the last 130ka. In order to generate a record for sea surface salinity (SSS) due to regional hydrological change, we removed the δ 18OSW signal due to glacial ice volume variation and normalized the residual to the modern δ 18OSW value for the Colombian Basin (0.8‰ ). The resulting ice volume-free (Δ δ 18OIVF-SW) record shows that Caribbean Δ δ 18OIVF-SW increased by ˜0.5‰ during the Last Glacial Maximum and Marine Isotope Stage 4. Using a modern western Caribbean δ 18OSW:SSS relationship, these enriched δ 18OSW values suggest glacial Caribbean salinities were 2.3 - 2.8‰ higher than modern after removing the influence of ice-volume. Our data supports the hypothesis that the tropics might have been in a state more similar to the modern El Nino mode, characterized by a more southerly position of the ITCZ, during cold phases of the last glacial cycle. Within the resolution of our Δ δ 18OIVF-SW record from VM28-122, elevated glacial Caribbean salinity decreased to modern levels at the onset of the Bolling-Allerod (B

    Saharan dust is transported across the Atlantic and interacts with the Caribbean seasonal climatic conditions, becoming respirable and contributing to asthma presentments at the emergency department. This study investigated the relationships among dust, climatic variables, and asthma-related visits to the emergency room in Grenada. All asthma visits to the emergency room ( n = 4411) over 5 years (2001-2005) were compared to the dust cover and climatic variables for the corresponding period. Variation in asthma was associated with change in dust concentration ( R 2 = 0.036, p < 0.001), asthma was positively correlated with rainfall ( R 2 = 0.055, p < 0.001), and rainfall was correlated with dust ( R 2 = 0.070, p = 0.003). Despite the similarities and the short distance between Trinidad, Barbados, and Grenada, they have markedly different geographies, cultures, population sizes, industrialization level, and economies. Therefore, different than from the studies in Trinidad and Barbados, Grenada is a non-industrialized low-income small island without major industrialized air pollution addition; asthma visits were inversely related to mean sea level pressure ( R 2 = 0.123, p = 0.006) and positively correlated with relative humidity ( R 2 = 0.593, p = 0.85). Saharan dust in conjunction with seasonal humidity allows for inhalable particulate matter that exacerbates asthma among residents in the Caribbean island of Grenada. These findings contribute evidence suggesting a broader public health impact from Saharan dust. Thus, this research may inform strategic planning of resource allocation among the Caribbean public health agencies.

    I review some unsolved problems in Caribbean active tectonics. At the regional and plate scale: 1) confirm the existence of intraplate deformation zones of the central Caribbean plate that are within the margin of error of ongoing GPS measurements; 2) carry out field studies to evaluate block models versus models for distributed fault shear on the densely populated islands of Jamaica, Hispaniola, Puerto Rico, and the Virgin Islands; 3) carry out paleoseismological research of key plate boundary faults that may have accumulated large strains but have not been previously studied in detail; 4) determine the age of onset and far-field effects of the Cocos ridge and the Central America forearc sliver; 4) investigate the origin and earthquake-potential of obliquely-sheared rift basins along the northern coast of Venezuela; 5) determine the age of onset and regional active, tectonic effects of the Panama-South America collision including the continued activation of the Maracaibo block; and 6) validate longterm rates on active subduction zones with improving, tomographic maps of subducted slabs. At the individual fault scale: 1) determine the mode of termination of large and active strike -slip faults and application of the STEP model (Septentrional, Polochic, El Pilar, Bocono, Santa Marta-Bucaramanaga); 2) improve the understanding of the earthquake potential on the Enriquillo-Plantain Garden fault zone given "off-fault" events such as the 2010 Haiti earthquake; how widespread is this behavior?; and 3) estimate size of future tsunamis from studies of historic or prehistoric slump scars and mass transport deposits; what potential runups can be predicted from this information?; and 4) devise ways to keep rapidly growing, circum-Caribbean urban populations better informed and safer in the face of inevitable and future, large earthquakes.

    Several studies conducted at the scale of islands, or small sections of continental coastlines, have suggested that mangrove habitats serve to enhance fish abundances on coral reefs, mainly by providing nursery grounds for several ontogenetically-migrating species. However, evidence of such enhancement at a regional scale has not been reported, and recently, some researchers have questioned the mangrove-reef subsidy effect. In the present study, using two different regression approaches, we pursued two questions related to mangrove-reef connectivity at the Caribbean regional scale: (1) Are reef fish abundances limited by mangrove forest area?; and (2) Are mean reef fish abundances proportional to mangrove forest area after taking human population density and latitude into account? Specifically, we tested for Caribbean-wide mangrove forest area effects on the abundances of 12 reef fishes that have been previously characterized as “mangrove-dependent”. Analyzed were data from an ongoing, long-term (20-year) citizen-scientist fish monitoring program; coastal human population censuses; and several wetland forest information sources. Quantile regression results supported the notion that mangrove forest area limits the abundance of eight of the 12 fishes examined. Linear mixed-effects regression results, which considered potential human (fishing and habitat degradation) and latitudinal influences, suggested that average reef fish densities of at least six of the 12 focal fishes were directly proportional to mangrove forest area. Recent work questioning the mangrove-reef fish subsidy effect likely reflects a failure to: (1) focus analyses on species that use mangroves as nurseries, (2) consider more than the mean fish abundance response to mangrove forest extent; and/or (3) quantitatively account for potentially confounding human impacts, such as fishing pressure and habitat degradation.

    Holocene relative sea-level (RSL) records from far-field locations are important for understanding the driving mechanisms controlling the nature and timing of the mid-late Holocene reduction in global meltwaters and providing background rates of late Holocene RSL change with which to compare the magnitude of 20th century RSL rise. The Caribbean region has traditionally been considered far-field (i.e., with negligible glacio-isostatic adjustment (GIA) influence), although recent investigations indicate otherwise. Here, we consider the spatial variability in glacio-isostatic, tectonic and local contributions on RSL records from the circum-Caribbean region to infer a Holocene eustatic sea-level signal. We have constructed a database of quality-controlled, spatially comprehensive, Holocene RSL observations for the circum-Caribbean region. The database contains over 500 index points, which locate the position of RSL in time and space. The database incorporates sea-level observations from a latitudinal range of 5°N to 25°N and longitudinal range of 55°W to 90°W. We include sea-level observations from 11 ka BP to present, although the majority of the index points in the database are younger than 8 ka BP. The database is sub-divided into 13 regions based on the distance from the former Laurentide Ice Sheet and regional tectonic setting. The index points were primarily derived from mangrove peat deposits, which in the Caribbean form in the upper half of the tidal range, and corals (predominantly Acropora palmata), the growth of which is constrained to the upper 5 m of water depth. The index points are classified on the basis of their susceptibility to compaction (e.g., intercalated, basal). The influence of temporal changes in tidal range on index points is also considered. The sea-level reconstructions demonstrate that RSL did not exceed the present height (0 m) during the Holocene in the majority of locations, except at sites in Suriname/Guayana and possibly Trinidad

    Sugarcane grown as energy cane presents a new potential to the Caribbean countries to provide their own energy needs and to reduce or eliminate fuel oil imports. The use of proper agronomic techniques can convert conventional sugarcane growing to a crop capable of giving energy feedstocks in the form of fiber for boiler fuel for electricity and fermentable solids for alcohol for motor fuel. Sugarcane can still be obtained from the energy cane for domestic consumption and export if desired. The aerable land now devoted to sugarcane can utilized for energy-cane production without causing any serious imbalance in food crop production.

    The interaction of the Caribbean, Cocos, Nazca, and South American plates has resulted in a complex plate boundary zone and the formation of second order tectonic blocks (e.g., the North Andean, Choco and Central America Fore Arc blocks). The Panama Region [PR], which is bounded by these plates and blocks, has been interpreted and modeled as a single tectonic block or deformed plate boundary. Previous research has defined the main boundaries: 1) The Caribbean plate subducts beneath the isthmus along the North Panama Deformed Belt, 2) The Nazca plate converges at very high obliquity with the PR and motion is assumed along a left lateral transform fault and the South Panama Deformed Belt, 3) The collision of PR with NW South America (i.e., the N. Andean and Choco blocks) has resulted in the Eastern Panama Deformed Belt, and 4) collision of the Cocos Ridge in the west is accommodated by crustal shortening, Central American Fore Arc translation and deformation across the Central Costa Rican Deformed Belt. In addition, there are several models that suggest internal deformation of this region by cross-isthmus strike-slip faults. Recent GPS observations for the PR indicates movement to the northeast relative to a stable Caribbean plate at rates of 6.9±4.0 - 7.8±4.8 mm a-1 from southern Costa Rica to eastern Panama, respectively (Kobayashi et al., 2014 and references therein). However, the GPS network did not have enough spatial density to estimate elastic strain accumulation across these faults. Recent installation and expansion of geodetic networks in southwestern Caribbean (i.e., Costa Rica, Panama, and Colombia) combined with geological and geophysical observations provide a new input to investigate crustal deformation processes in this complex tectonic setting, specifically related to the PR. We use new and existing GPS data to calculate a new velocity field for the region and to investigate the kinematics of the PR, including elastic strain accumulation on the

    Sugar cane presents tremendous potential as a renewable energy source for the non-oil-producing, developing countries of the Caribbean basin. The analysis presented here, finds the overall energy balance to be extremely favorable. The economics are also favorable, even though capital investment requirements are high. Potential for improvement, in both the energy balance and the economic aspects, is very great. Such improvement is attainable by the development of new technology, which could be available in the short term and at moderate cost. (Refs. 8).

    The Caribbean steelpan is one of the most interesting acoustic musical instruments invented in the last century. Although simple in design, the acoustic properties of the steelpan are surprisingly complicated. Holographic interferometry was used to determine the modes of vibration of a double second and a low tenor steelpan. Sound intensity measurements were taken to explore the relationship between the modes of vibration and the radiated sound field. The pan was placed in an anechoic chamber, and selected notes were excited electromagnetically with a swept sinusoid signal. A two-microphone probe was used to gather sound intensity measurements. Sound intensity maps and animations were constructed for the first three harmonics.

    The northeastern Caribbean provides a natural laboratory to investigate strain partitioning, its causes and its consequences on the stress regime and tectonic evolution of a subduction plate boundary. Here, we use GPS and earthquake slip vector data to produce a present-day kinematic model that accounts for secular block rotation and elastic strain accumulation, with variable interplate coupling, on active faults. We confirm that the oblique convergence between Caribbean and North America in Hispaniola is partitioned between plate boundary parallel motion on the Septentrional and Enriquillo faults in the overriding plate and plate-boundary normal motion at the plate interface on the Northern Hispaniola Fault. To the east, the Caribbean/North America plate motion is accommodated by oblique slip on the faults bounding the Puerto Rico block to the north (Puerto Rico subduction) and to the south (Muertos thrust), with no evidence for partitioning. The spatial correlation between interplate coupling, strain partitioning and the subduction of buoyant oceanic asperities suggests that the latter enhance the transfer of interplate shear stresses to the overriding plate, facilitating strike-slip faulting in the overriding plate. The model slip rate deficit, together with the dates of large historical earthquakes, indicates the potential for a large (Mw7.5 or greater) earthquake on the Septentrional fault in the Dominican Republic. Similarly, the Enriquillo fault in Haiti is currently capable of a Mw7.2 earthquake if the entire elastic strain accumulated since the last major earthquake was released in a single event today. The model results show that the Puerto Rico/Lesser Antilles subduction thrust is only partially coupled, meaning that the plate interface is accumulating elastic strain at rates slower than the total plate motion. This does not preclude the existence of isolated locked patches accumulating elastic strain to be released in future earthquakes, but whose

    During the last twenty years, Hispanic Caribbean cinema has slowly developed roles to represent lesbians. In order to draw a conceptual map and to examine the un/successfulness of this new lesbian "public image," I analyze both independent films that challenge the status quo by portraying openly lesbian characters and mainstream films that insist on denying autonomy to same-sex love. Whereas commercial markets may deem an openly lesbian role transgressive, queer female roles can be considered "appropriate." Gender-queering functions as a symbolically transitional stage toward lesbian visibility and inclusion. PMID:22702379

    2015-12-01

    The progressive closing of the Central American Seaway ~3-7 Ma substantially altered the surface ocean salinity, nutrient content, and biology of the Caribbean Sea and Eastern Equatorial Pacific Ocean. Data from fossil plankton, reef development and oceanographic models of the shoaling Central American Seaway suggest that there was a distinct change in Caribbean productivity with closure of the seaway, but there has not been a detailed comparison of export production between the two ocean basins. Here we show that export production gradually decreased in the Caribbean starting about 2.7 Ma while remaining relatively stable in the eastern equatorial Pacific. Data are derived from 0-5.3 Ma XRF records of Caribbean Site ODP 999 and Pacific Site ODP 846 at ~600-1000 year resolution. Caribbean export production falls during glacial phases in response to ventilation of the tropical thermocline by increasingly nutrient-starved Glacial North Atlantic Intermediate Water. In contrast, Caribbean production peaks during interglacials when nutrient-rich Antarctic Intermediate Water ventilates the tropical thermocline. Export production in both the eastern Pacific and Caribbean is governed mostly by high latitude nutrient sources as seen in the dominance of high latitude orbital forcing. The gradual intensification of Caribbean oligotrophy may be responsible for the well documented delay in extinction of Caribbean reef associated fauna relative to closure of the central American Seaway. The increasing nutrient starvation of the Caribbean during glacial events may also have rendered Caribbean reef corals unusually susceptible to anthropogenic nutrient loads in modern times.

    A very high prevalence of multiple sclerosis (MS) has been reported in some Western European and North American countries. The few surveys of MS epidemiology in South America reveal lower prevalence rates, implying that susceptibility varies between distinct ethnic groups, thus forming an important determinant of the geographic distribution of the disease. The objective of this study is to review MS prevalence estimates in different Latin American and Caribbean countries. We reviewed surveys of regional MS prevalence from 1991 to 2011. Sources included an online database, authors' reports and proceedings or specific lectures from regional conferences. We obtained a total of 30 prevalence surveys from 15 countries, showing low/medium MS prevalence rates. Both the number and the quality of prevalence surveys have greatly improved in this region over recent decades. This is the first collaborative study to map the regional frequency of MS. Establishment of standardized methods and joint epidemiological studies will advance future MS research in Latin America and the Caribbean. PMID:22492129

    Ocean temperatures are increasing globally and the Caribbean is no exception. An extreme ocean warming event in 2010 placed Tobago's coral reefs under severe stress resulting in widespread coral bleaching and threatening the livelihoods that rely on them. The bleaching response of four reef building taxa was monitored over a six month period across three major reefs systems in Tobago. By identifying taxa resilient to bleaching we propose to assist local coral reef managers in the decision making process to cope with mass bleaching events. The bleaching signal (length of exposure to high ocean temperatures) varied widely between the Atlantic and Caribbean reefs, but regardless of this variation most taxa bleached. Colpophyllia natans, Montastraea faveolata and Siderastrea siderea were considered the most bleaching vulnerable taxa. Interestingly, reefs with the highest coral cover showed the greatest decline reef building taxa, and conversely, reefs with the lowest coral cover showed the most bleaching but lowest change in coral cover with little algal overgrowth post-bleaching.

    Unique experience has accumulated in the English-speaking Caribbean in the field of family life education for youth. Although birth rates are relatively low, the increase in adolescent pregnancy and births is becoming more visible. Mother-centered homes are frequent, and support from the father is often lacking. A series of family life education (FLE) programs funded by the United National Fund for Population Activities is aimed at providing help to the various groups in the Caribbean in an acceptable and non-threatening manner. These out-of-school FLE techniques include several approaches: integration of the proposed program into an already established place (a factory, youth center, or community center); education in human growth, food and nutrition, environmental health, mental health, safety and first-aid, dental health and human relations, including human sexuality, rights and responsibilities, and decision making; and the use of specially trained personnel who understand the conditions of the particular community. In some countries adolescent pregnancy is viewed as a problem. In others it may not be so considered. It is vital for the staff and community leaders to review proposals for the FLE program and bring into the centers all subjects that are free of controversy. Family planning, contraceptive delivery and even human sexuality may be acceptable subjects in some quarters, and not in others. Efforts must be continued to find innovative approaches to assure that the benefits of these learning activities continue to be provided, and expanded in response to growing acceptance. PMID:3745503

    Central America and the Caribbean have not enjoyed the same high profile as more prominent independent power markets like India and China. Indeed, only one country in the region appeared in a recent survey of the 20 most promising markets: Panama, with a projected demand for 2,040 megawatts (MW) of new capacity, was ranked twentieth. Nevertheless, taken as a whole, Central America and the Caribbean offer significant opportunities for new development. Projected incremental capacity needs in some of the larger markets in the region include: Costa Rica (700-1,000 MW), Dominican Republic (1,100 MW), Guatemala (450 MW), Honduras (225 MW), Jamaica (729 MW), Panama (2,040 MW), and Trinidad & Tobago (200 MW). These markets represent an aggregate potential demand of 5,750 MW - more than the projected demand in Colombia, one of South America`s most active markets. Yet although its need for capacity is significant, the region presents developers with unique challenges because it comprises so many relatively small countries, each with its own special needs and characteristics.

    2006-07-25

    A substantial and increasing number of reports have documented dramatic changes and continuing declines in Caribbean coral reef communities over the past 2 decades. To date, the majority of disease reports have focused on scleractinian corals, whereas sponge diseases have been less frequently documented. In this study, we describe Aplysina red band syndrome (ARBS) affecting Caribbean rope sponges of the genus Aplysina observed on shallow reefs in the Bahamas. Visible signs of disease presence included 1 or more rust-colored leading edges, with or without a trailing area of necrotic tissue, such that the lesion forms a contiguous band around part or all of the sponge branch. Microscopic examination of the leading edge of the disease margin indicated that a cyanobacterium was consistently responsible for the coloration. Although the presence of this distinctive coloration was used to characterize the diseased state, it is not yet known whether this cyanobacterium is directly responsible for disease causation. The prevalence of ARBS declined significantly from July to October 2004 before increasing above July levels in January 2005. Transmission studies in the laboratory demonstrated that contact with the leading edge of an active lesion was sufficient to spread ARBS to a previously healthy sponge, suggesting that the etiologic agent, currently undescribed, is contagious. Studies to elucidate the etiologic agent of ARBS are ongoing. Sponges are an essential component of coral reef communities and emerging sponge diseases clearly have the potential to impact benthic community structure on coral reefs. PMID:16956064

    This article focuses on developing a sustainable tourism in small Caribbean islands, defined here as those that have populations of fewer than 500,000. Such islands share a very fragile ecology and a high dependence on tourism. They differ in their degree of tourist penetration and visitor density and the related degree of environmental degradation. To explain the link between tourism intensity and ecological vulnerability, the so-called “destination life-cycle model” is presented. This suggests that islands pass through three primary stages of tourist development low-density exploration, rapid growth and consolidation, and high-density maturation involving the substitution of man-made for natural attractions. A broad empirical test of the model is performed through a quantitative examination of the tourism characteristics and visitor densities of a cross section of 23 small Caribbean islands. The three basic stages or tourism styles are identified: low-impact emerging areas, high-density mass-market mature destinations, and rapidly growing intermediate islands in between. Some broad strategies consistent with the systems framework for a sustainable tourism with moderate densitites are briefly explored.

    This paper presents the results of a study commissioned by the Latin American and Caribbean Technical Department of the World Bank to document and analyze health expenditures in Latin America and the Caribbean. In 1990, the countries of this region spent US$ 69 billion on health, with an average per capita health expenditure of US$ 162. On average, the countries spent 6.2% of their GDP on health, with the expenditures divided about equally between the public and private sectors. In both the public and private sectors, per capita health expenditures were positively and significantly correlated with per capita income. However, this relationship holds only for the public sector, when health expenditures are measured as a proportion of GDP. While several poorer countries were dependent on external assistance, with increasing income, the countries relied more on public expenditures to finance health care. Based on the limited time series data, it is evident that there was a considerable variation among countries regarding the proportion spent on capital investments, primary health care, and drugs, but not on salaries. Looking ahead, with increasing economic development, the proportion of GDP spent on health, along with public health expenditure as a proportion of total health expenditure, is likely to increase rapidly, while aid dependency is likely to decline.

    Over 75 tsunamis have been documented in the Caribbean and Adjacent Regions over the past 500 years. While most have been generated by local earthquakes, distant generated tsunamis can also affect the region. For example, waves from the 1755 Lisbon earthquake and tsunami were observed in Cuba, Dominican Republic, British Virgin Islands, as well as Antigua, Martinique, Guadalupe and Barbados in the Lesser Antilles. Since 1500, at least 4484 people are reported to have perished in these killer waves. Although the tsunami generated by the 2010 Haiti earthquake claimed only a few lives, in the 1530 El Pilar, Venezuela; 1602 Port Royale, Jamaica; 1918 Puerto Rico; and 1946 Samaná, Dominican Republic tsunamis the death tolls ranged to over a thousand. Since then, there has been an explosive increase in residents, visitors, infrastructure, and economic activity along the coastlines, increasing the potential for human and economic loss. It has been estimated that on any day, upwards of more than 500,000 people could be in harm's way just along the beaches, with hundreds of thousands more working and living in the tsunamis hazard zones. Given the relative infrequency of tsunamis, exercises are a valuable tool to test communications, evaluate preparedness and raise awareness. Exercises in the Caribbean are conducted under the framework of the UNESCO IOC Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS) and the US National Tsunami Hazard Mitigation Program. On March 23, 2011, 34 countries and territories participated in the first CARIBE WAVE/LANTEX regional tsunami exercise, while in the second exercise on March 20, 2013 a total of 45 countries and territories participated. 481 organizations (almost 200 more than in 2011) also registered to receive the bulletins issued by the Pacific Tsunami Warning Center (PTWC), West Coast and Alaska Tsunami Warning Center and/or the Puerto Rico

  13. Wind Energy Resource Assessment of the Caribbean and Central America

    A wind energy resource assessment of the Caribbean and Central America has identified many areas with good to outstanding wind resource potential for wind turbine applications. Annual average wind resource maps and summary tables have been developed for 35 island/country areas throughout the Caribbean and Central America region. The wind resource maps highlight the locations of major resource areas and provide estimates of the wind energy resource potential for typical well-exposed sites in these areas. The average energy in the wind flowing in the layer near the ground is expressed as a wind power class: the greater the average wind energy, the higher the wind power class. The summary tables that are included with each of the 35 island/country wind energy maps provide information on the frequency distribution of the wind speeds (expressed as estimates of the Weibull shape factor, k) and seasonal variations in the wind resource for the major wind resource areas identified on the maps. A new wind power class legend has been developed for relating the wind power classes to values of mean wind power density, mean wind speed, and Weibull k. Guidelines are presented on how to adjust these values to various heights above ground for different roughness and terrain characteristics. Information evaluated in preparing the assessment included existing meteorological data from airports and other weather stations, and from ships and buoys in offshore and coastal areas. In addition, new data from recent measurement sites established for wind energy siting studies were obtained for a few areas of the Caribbean. Other types of information evaluated in the assessment were climatological data and maps on winds aloft, surface pressure, air flow, and topography. The various data were screened and evaluated for their usefulness in preparing the wind resource assessment. Much of the surface data from airports and other land-based weather stations were determined to be from sheltered

    The currently accepted kinematic model of the Caribbean plate presented by DeMets et al. (2007) is based on velocities from 6 continuous and 14 campaign GPS sites. COCONet is a multi-hazard GPS-Met observatory, which extends the existing infrastructure of the Plate Boundary Observatory in North America into the Caribbean basin. In 2010, UNAVCO in collaboration with UCAR, was funded by NSF to design, build, and initially maintain a network of 50 new cGPS/Met sites and include data from another 50 existing sites in the Caribbean region. The current COCONet siting plan calls for 46 new stations, 21 refurbished stations, and 77 existing stations across 26 nations in the Caribbean region. Data from all COCONet sites flow into the UNAVCO archive and are processed by the PBO analysis centers and are also processed independently by the UTA Geodesy Lab using GIPSY-OASISII (v.6.2) using an absolute point positioning strategy and final, precise orbits, clocks, and Earth orientation parameters from JPL in the IGS08 frame. We present here our refined estimate of Caribbean plate motion by evaluating data from an expanded number of stations with an improved spatial distribution. In order to better constrain the eastern margin of the plate near the Lesser Antilles subduction interface, campaign GPS observations have been collected on the island of Dominica over the last decade. These are combined with additional campaign observations from the western Caribbean, specifically from Honduras and Nicaragua. We have analyzed a total of 117 sites from the Caribbean region, including campaign data and the data from the cGPS stations that comprise COCONet. An updated velocity field for the Caribbean plate is presented and an inversion of the velocities for 24 sites yields a plate angular velocity that differs from previously published models. Our best fitting inversion to GPS velocities from these 24 sites suggests that 2-plate model for the Caribbean is required to fit the GPS

    Mimallonidae of the Caribbean Basin are discussed, with attention primarily given to species endemic to the Caribbean islands and the northern coast of Venezuela. The Caribbean Basin is a political term for tropical regions circumscribed by the Gulf of Mexico. Cicinnus bahamensis sp. n. is described from the Bahamas, the first species of Mimallonidae from this country. The Cuban species Cicinnus packardii (Grote, 1865), the closest relative of C. bahamensis sp. n., is figured and compared. A third, similar, species from northern coastal Venezuela, C. falcoargenteus sp. n., is described and compared to the previous two species. PMID:27394281

    The thick oceanic crust of the Caribbean plate appears to be the tectonized remnant of an eastern Pacific oceanic plateau that has been inserted between North and South America. The emplacement of the plateau into its present position has resulted in the obduction and exposure of its margins, providing an opportunity to study the age relations, internal structure and compositional features of the plateau. We present the results of 40Ar- 39Ar radiometric dating, major-, trace-element, and isotopic compositions of basalts from some of the exposed sections as well as drill core basalt samples from Leg 15 of the Deep Sea Drilling Project. Five widely spaced, margin sections yielded ages ranging from 91 to 88 Ma. Less well-constrained radiometric ages from the drill cores, combined with the biostratigraphic age of surrounding sediments indicate a minimum crystallization age of ˜90 Ma in the Venezuelan Basin. The synchroneity of ages across the region is consistent with a flood basalt origin for the bulk of the Caribbean plateau (i.e., large volume, rapidly erupted, regionally extensive volcanism). The ages and compositions are also consistent with plate reconstructions that place the Caribbean plateau in the vicinity of the Galápagos hotspot at its inception. The trace-element and isotopic compositions of the ˜90 Ma rocks indicate a depleted mantle and an enriched, plume-like mantle were involved in melting to varying degrees across the plateau. Within the same region, a volumetrically secondary, but widespread magmatic event occurred at 76 Ma, as is evident in Curaçao, western Colombia, Haiti, and at DSDP Site 152/ODP Site 1001 near the Hess Escarpment. Limited trace-element data indicate that this phase of magmatism was generally more depleted than the first. We speculate that magmatism may have resulted from upwelling of mantle, still hot from the 90 Ma event, during lithospheric extension attending gravitational collapse of the plateau, and/or tectonic

    Comparisons of carbon isotopic data on benthic foraminifera from Deep Sea Drilling Project sites 502 (western Caribbean) and 503 (eastern Pacific) indicate that the difference between the Atlantic and the Pacific in the per mil enrichment in carbon-13 of total dissolved carbon dioxide increased about 6 million years ago and again 3 million years ago, when the difference reached the modern level (1 per mil). Comparisons of planktonic foraminiferal oxygen isotopic data for the Caribbean and the Pacific suggest that the salinity of Caribbean surface waters began increasing 4 million years ago, possibly in response to shoaling of the Panama isthmus. These results suggest that modern circulation patterns in the Caribbean and eastern Pacific developed by 3 million years ago in concert with changing tectonic, climatic, and biogeographic patterns.

    Between July 2000 and August 2001 forty-three air samples were collected in the northern Caribbean: Twenty-six in the US Virgin Islands, and 17 samples aboard ship during two 1-week cruises. Samples were collected during African dust events and non-dust conditions and screened for the presence of culturable bacteria and fungi. A total of 3,652 liters of air were collected during non-dust conditions, with 19 bacteria and 28 fungi being recovered. During dust conditions a total of 2,369 liters of air were screened resulting in the recovery of 171 bacteria and 76 fungi. A statistically significant difference was found between the two data sets. These results support previous African dust research and further demonstrate that dust particles can serve as a vessel for the global dispersion of bacteria and fungi. Dustborne microorganisms may play a significant role in the ecology and health of downwind ecosystems.

    The southern Caribbean-South American plate boundary has many similarities to California's San Andreas system: 1) The CAR-SA system consists of a series of strands of active right lateral strike-slip faults extending >1000 km from the Antilles subduction zone. This system has several names and includes the El Pilar, Coche, San Sebastian, Moron, and Oca faults. 2) The CAR-SA relative velocity has been about 20 mm/yr of mostly right lateral motion since about 55 Ma, giving a total displacement on the CAR-SA plate boundary similar to that of the San Andreas system. 3) The plate boundary has about 10% convergence in western SA, with less as one moves eastward due to relative convergence between North and South America. 4) The CAR-SA system has fold and thrust belts best developed continentward of the strike-slip faults, similar to the San Andreas. 5) There is a big bend in the CAR plate boundary at approximately the same distance from the Antilles trench as the big bend in Southern California is from the Cascadia subduction zone. The tectonic origins of the CAR-SA plate boundary and the San Andreas are very different, however, despite the similarities between the systems. Rather than impingement of a ridge on a trench, the CAR-SA system is thought to have resulted from a continuous oblique collision of the southern end of a Cretaceous island arc system with the northern edge of South America. During this process the CAR island arc and the modern CAR plate overrode a proto-Caribbean plate and destroyed a Mesozoic passive margin on the northern edge of SA. BOLIVAR and GEODINOS are multi-disciplinary investigations of the lithosphere and deeper structures associated with the diffuse CAR-SA plate boundary zone. We review a number of observations regarding the plate boundary obtained or confirmed from these studies: 1) The Caribbean Large Igneous Province, being overridden by the Maracaibo block in western Venezuela, can be identified beneath Aruba and coastal Venezuela

    Following the catastrophic loss of life from the December 26, 2004, Sumatra-Andaman Islands earthquake and tsunami, the U.S. Government appropriated funds to improve monitoring along a major portion of vulnerable coastal regions in the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean. Partners in this project include the United States Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the Puerto Rico Seismic Network (PRSN), the Seismic Research Unit of the University of the West Indies, and other collaborating institutions in the Caribbean region. As part of this effort, the USGS is coordinating with Caribbean host nations to design and deploy nine new broadband and strong-motion seismic stations. The instrumentation consists of an STS-2 seismometer, an Episensor accelerometer, and a Q330 high resolution digitizer. Six stations are currently transmitting data to the USGS National Earthquake Information Center, where the data are redistributed to the NOAA's Tsunami Warning Centers, regional monitoring partners, and the IRIS Data Management Center. Operating stations include: Isla Barro Colorado, Panama; Gun Hill Barbados; Grenville, Grenada; Guantanamo Bay, Cuba; Sabaneta Dam, Dominican Republic; and Tegucigalpa, Honduras. Three additional stations in Barbuda, Grand Turks, and Jamaica will be completed during the fall of 2007. These nine stations are affiliates of the Global Seismographic Network (GSN) and complement existing GSN stations as well as regional stations. The new seismic stations improve azimuthal coverage, increase network density, and provide on-scale recording throughout the region. Complementary to this network, NOAA has placed Deep-ocean Assessment and Reporting of Tsunami (DART) stations at sites in regions with a history of generating destructive tsunamis. Recently, NOAA completed deployment of 7 DART stations off the coasts of Montauk Pt, NY; Charleston, SC; Miami, FL; San Juan, Puerto Rico; New

    Aviation technology can play a significant role in the development of the countries of the Caribbean Basin. A variety of applications of rotorcraft in the region, the benefits, both economic and political which can result from utilization of rotorcraft in both a public service and commercial role are presented. A computer simulation of rotorcraft used as emergency medical vehicles is applied to compare and evaluate the advantages of using rotorcraft technology such as civil derivatives of the new tiltrotor. It is concluded that by using a civil derivative of the tiltrotor, significant improvements can be obtained in the level of health service in the region. The potential for cargo and passenger transport applications are currently being investigated and a second computer simulation is being developed to be used to evaluate the potential benefits to be derived from such applications.

    Scientists surveying the Cayman Trough in the Caribbean Sea have discovered the world's deepest undersea volcanic vents, or “black smokers,” the National Oceanography Center (NOC) in Southampton, UK, announced on 11 April. The vents were found at a depth of 5000 meters, about 800 meters deeper than any previously discovered. Jon Copley, a marine biologist at the University of Southampton's School of Ocean and Earth Science, said, “Seeing the world's deepest black-smoker vents looming out of the darkness was awe-inspiring.” Geochemist Doug Connelly of NOC, principal scientist of the expedition, noted, “We hope our discovery will yield new insights into biogeochemically important elements in one of the most extreme naturally occurring environments on our planet.” Researchers used an NOC-developed Autosub6000 robot submarine, which was remotely controlled from the Royal Research Ship James Cook.

    We reviewed the adoption and implementation of smokefree policies in all Latin American and the Caribbean (LAC) countries. Significant progress has been achieved among LAC countries since the WHO Framework Convention on Tobacco Control (FCTC) was adopted in 2005. Both national and sub-national legislation have provided effective mechanisms to increase the fraction of the population protected from secondhand tobacco smoke. Civil society has actively promoted these policies and played a main role in enacting them and monitoring their enforcement. The tobacco industry, while continuing to oppose the approval and regulation of the laws at legislative and executive levels, has gone a step further by litigating against them in the Courts. As in the US and elsewhere, this litigation has failed to stop the legislation. PMID:22754484

    A pilot designed to improve the capabilities of Caribbean universities and research institutes in helping solve the energy problems of the region is discussed. Most of the region is almost entirely dependent on imported petroleum to satisfy its energy needs. That dependency has exascerbated economic problems with the escalation of petroleum prices in the past ten years. A potential solution to reduce both the high degree of dependence and economic costs is to develop other energy systems. A project to foster cooperative research efforts to assist in the introduction of alternative energy solutions was developed. A network of scientists and engineers working in energy was established to promote cooperation, interchange of technical information and development of joint projects.

    There are few long-term datasets available to make reliable statements about trends in cover and structure in many coral reefs around the world. We present 27year old summary data of the cover of corals and other biota on Caribbean and Western Atlantic coral reefs in 7 countries collected in late 1985 and early 1986. These data were collected to support research on sponge populations and show relatively low coral cover on many of these reefs with particularly low cover of Acropora spp. We present these summaries to encourage other researchers to compare with current conditions or repeat the surveys to show long-term trends; the raw data will be supplied on request.

    2012-01-01

    Background The strategies that parents use to guide and discipline their children may influence their emotional health. Relatively little research has been conducted examining the association of parenting practices to depressive symptoms among Caribbean adolescents. This project examines the association of parenting styles to levels of depressive symptoms among adolescents in Jamaica, the Bahamas, St. Kitts and Nevis, and St. Vincent. Methods Adolescents attending grade ten of academic year 2006/2007 in Jamaica, the Bahamas, St. Vincent, and St. Kitts and Nevis were administered the Parenting Practices Scale along with the BDI-II. Authoritative, Authoritarian, Permissive and Neglectful parenting styles were created using a median split procedure of the monitoring and nurturance subscales of the Parenting Practices Scale. Multiple regression analyses were used to examine the relationships of parenting styles to depressive symptoms. Results A wide cross-section of tenth grade students in each nation was sampled (n = 1955; 278 from Jamaica, 217 from the Bahamas, 737 St. Kitts and Nevis, 716 from St. Vincent; 52.1% females, 45.6% males and 2.3% no gender reported; age 12 to 19 years, mean = 15.3 yrs, sd = .95 yrs). Nearly half (52.1%) of all adolescents reported mild to severe symptoms of depression with 29.1% reporting moderate to severe symptoms of depression. In general, authoritative and permissive parenting styles were both associated with lower levels of depressive symptoms in adolescents. However, the relationship of parenting styles to depression scores was not consistent across countries (p < .05). In contrast to previous research on Caribbean parenting, caregivers in this study used a mixture of different parenting styles with the two most popular styles being authoritative and neglectful parenting. Conclusions There appears to be an association between parenting styles and depressive symptoms that is differentially manifested across the

    Recent empirical studies have demonstrated that human activities such as fishing can strongly affect the natural capital and services provided by tropical seascapes. However, policies to mitigate anthropogenic impacts can also alter food web structure and interactions, regardless of whether the regulations are aimed at single or multiple species, with possible unexpected consequences for the ecosystems and their associated services. Complex community response to management interventions have been highlighted in the Caribbean, where, contrary to predictions from linear food chain models, a reduction in fishing intensity through the establishment of a marine reserve has led to greater biomass of herbivorous fish inside the reserve, despite an increased abundance of large predatory piscivores. This positive multi-trophic response, where both predators and prey benefit from protection, highlights the need to take an integrated approach that considers how numerous factors control species coexistence in both fished and unfished systems. In order to understand these complex relationships, we developed a general model to examine the trade-offs between fishing pressure and trophic control on reef fish communities, including an exploration of top-down and bottom-up effects. We then validated the general model predictions by parameterizing the model for a reef system in the Bahamas in order to tease apart the wide range of species responses to reserves in the Caribbean. Combining the development of general theory and site-specific models parameterized with field data reveals the underlying driving forces in these communities and enables us to make better predictions about possible population and community responses to different management schemes.

    Two unusually massive ostreid species, representing the largest and youngest Mesozoic members of their respective lineages, occur in Upper Cretaceous sediment of the gulf coast and Caribbean areas. Their characteristics and significance, as well as the morphologic terminology of ostreids in general, are discussed. Crassostrea cusseta Sohl and Kauffman n. sp. is the largest known ostreid from Mesozoic rocks of North America; it occurs sporadically in the Cusseta Sand and rarely in the Blufftown Formation of the Chattahoochee River region in Georgia and Alabama. It is especially notable in that it lacks a detectable posterior adductor muscle scar on large adult shells. C. cusseta is the terminal Cretaceous member of the C. soleniscus lineage in gulf coast sediments; the lineage continues, however, with little basic modification, throughout the Cenozoic, being represented in the Eocene by C. gigantissima (Finch) and probably, in modern times, by C. virginica (Gmelin). The C. soleniscus lineage is the first typically modern crassostreid group recognized in the Mesozoic. Arctostrea aguilerae (Böse) occurs in Late Campanian and Early Maestrichtian sediments of Alabama, Mississippi, Texas(?), Mexico, and Cuba. The mature shell of this species is larger and more massive than that of any other known arctostreid. Arctostrea is well represented throughout the Upper Jurassic and Cretaceous of Europe, but in North America, despite the great numbers and diversity of Cretaceous oysters, only A. aguilerae and the Albian form A. carinata are known. The presence of A. aquilerae in both the Caribbean and gulf coast faunas is exceptional, as the Late Cretaceous faunas of these provinces are generally distinct and originated in different faunal realms.

    1993-02-15

    This special section of the Journal of Geophysical Research reports a multi-investigator study of a number of sunlight-initiated photoprocesses taking place in the varied biogeochemical and oceanographic environment found in the tropical Eastern Caribbean and Orinoco River delta in the spring and fall of 1988. Principal conceptual themes that were addressed by the program included (1) the characterization of the role of dissolved organic matter as the main chromophore initiating photoprocesses in surface seawater, (2) the determination of the fluxes and pathways of reactants and transient species involved in oxygen photoredox chemistry, and (3) the continuing development of chemical mapping strategies, including observing and modelling reactive phototransient distribution in terms of their sources, mixing, and fates. Ancillary supporting studies included observation of water mass tracers, dissolved trace gases, atmospheric components, nutrients and the geochemistry of estuarine mixing processes in an important continental margin. The observational and mechanistic investigations reported here feature a number of novel or improved methods allied with some advanced underway sampling, sensing and computing facilities that were implemented aboard the R/V Columbus Iselin. Results from the study showed large-scale ([approximately]1,000 km) seasonal variations in surface water photoreactivity, optical and biooptical characteristics over much of the Caribbean basin. These changes resulted from seasonally varying riverine inputs of organic chromophores, nutrients and suspended material. Smaller scale (10-100 km) studies carried out in the Orinoco delta and the Gulf of Paria showed that estuarine mixing processes did not affect major net removal of dissolved organic matter, consistent with the hypothesis that riverine chromophore input plays a dominant role in open-water photochemistry. 56 refs., 4 figs., 1 tab.

    The southwestern corner of the Caribbean Sea is considered a coastal warm pool oceanographically linked to the Panama Colombia Gyre. The atmosphere - ocean variability there is influenced by the Intertropical Convergence Zone (ITZC), the Andean river runoff, the northeasterly trade winds, and a tropical low level jet (San Andrés jet), all of them connected to global variability. This warm pool has a significant (>95%) warming trend (0.6°C between 1981 and 2000), with the warmest record just in front of the Sinu River, where Isla Fuerte is located, 11 km from the coast, to the western of Sinu Delta. Sea surface temperature (SST) and the Multivariate ENSO index have a significant (>95%) correlation of 0.4 with a 7 months lag. The Sinu River flow does not show a long trend between 1985 and 2000, but has a significant correlation with ENSO (0.5) with no lag. Two corals from Isla Fuerte, a Siderastrea siderea colony with a maximum length of 72.5 cm and a Montastrea annularis colony of 30.5 cm, were studied in order to test the climatic potential of these records and to understand the oceanographic variability at the SW Caribbean. Fluorescence has better resolution than density bands in both corals. Chronology based on them indicates an age of 127 and 32 years respectively. We present and discuss growth and Sr/Ca series. The signal is produced by the interaction between the river flow and local winds. The river reaches the island when northeastern winds deflect their plume to the east. However, there are not in situ instrumental records for calibration and interpretation of the signals and we used world data bases with low spatial resolution.

  19. Paleoproxies as Indicators of Water Mass Changes in the Caribbean

    Paleotemperature proxies derived from coral and sclerosponge skeletons collected from the Caribbean Sea and surrounding areas (Bahamas, Jamaica, Pedro Bank, Exuma Sound, Puerto Rico, and Guadeloupe) suggest temperature increases in excess of 1oC over the past century. Such increases are greater than those commonly accepted for global warming of surface oceans which is between 0.2 and 0.5oC. The question arises as to why water temperature in the sub-tropics, which were not as responsive to glacial-interglacial temperature changes, should show a greater response during the present anthropogenically induced warming. Here, we present reconstructed salinity data (using Sr/Ca and δ18O) measured in a number of sclerosponges collected from between 67 and 136 m water depth in the Bahamas. This study uses a modified temperature equation with respect to Sr/Ca for sclerosponges, which incorporates individuals which grew in colder water conditions. While this equation reduces somewhat the higher temperature change estimates calculated previously, these records still corroborate the high rates of temperature increase in the 20th century, even in at depths up to 150m, and illustrate a shoaling of high-salinity waters isopycnally transported into the Caribbean in the shallow subsurface (50-300 m). Decadal scale variability in these proxy records reflect variations in the origin of open ocean water masses, whereas long term trends are interpreted as shifts in the depths of the important subtropical and tropical halocline depths. This suggests changes in subsurface transport from subtropical cells rather than extreme warming of any singular water mass and is indicative of the heterogeneous nature of anthropogenic climate variability in the climate system's largest heat reservoir.

    Coastal mangroves lose large amounts of water through evapotranspiration (ET) that can be equivalent to the amount of annual rainfall in certain years. Satellite remote sensing has been used to estimate surface energy and ET variability in many forested ecosystems, yet has been widely overlooked in mangrove forests. Using a combination of long-term datasets (30-year) acquired from the NASA Landsat 5 and 7 satellite databases, the present study investigated ET and surface energy balance variability between two mangrove forest sites in the Caribbean: 1) Everglades National Park (ENP; Florida, USA) and 2) Sian Ka'an Biosphere Reserve (SKBR; Quintana Roo, Mexico). A satellite-derived surface energy balance model was used to estimate ET in tall and scrub mangroves environments at ENP and SKBR. Results identified significant differences in soil heat flux measurements and ET between the tall and scrub mangrove environments. Scrub mangroves exhibited the highest soil heat flux coincident with the lowest biophysical indices (i.e., Fractional Vegetation Cover, Normalized Difference Vegetation Index, and Soil-Adjusted Vegetation Index) and ET rates. Mangrove damage and mortality was observed on the satellite images following strong tropical storms and associated with anthropogenic modifications and resulted in low values in spectral vegetation indices, higher soil heat flux, and higher ET. Recovery of the spectral characteristics, soil heat flux and ET was within 1-2 years following hurricane disturbance while, degradation caused by human disturbance persisted for many years. Remotely sensed ET of mangrove forests can provide estimates over a few decades and provide us with some understanding of how these environments respond to disturbances to the landscape in periods where no ground data exists or in locations that are difficult to access. Moreover, relationships between energy and water balance components developed for the coastal mangroves of Florida and Mexico could be

    OBJECTIVE: To measure the economic burden associated with diabetes mellitus in Latin America and the Caribbean. METHODS: Prevalence estimates of diabetes for the year 2000 were used to calculated direct and indirect costs of diabetes mellitus. Direct costs included costs due to drugs, hospitalizations, consultations and management of complications. The human capital approach was used to calculate indirect costs and included calculations of forgone earnings due to premature mortality and disability attributed to diabetes mellitus. Mortality and disability attributed to causes other than diabetes were subtracted from estimates to consider only the excess burden due to diabetes. A 3% discount rate was used to convert future earnings to current value. FINDINGS: The annual number of deaths in 2000 caused by diabetes mellitus was estimated at 339,035. This represented a loss of 757,096 discounted years of productive life among persons younger than 65 years (> billion US dollars). Permanent disability caused a loss of 12,699,087 years and over 50 billion US dollars, and temporary disability caused a loss of 136,701 years in the working population and over 763 million US dollars. Costs associated with insulin and oral medications were 4720 million US dollars, hospitalizations 1012 million US dollars, consultations 2508 million US dollars and care for complications 2,480 million US dollars. The total annual cost associated with diabetes was estimated as 65,216 million US dollars (direct 10,721 US dollars; indirect 54,496 US dollars). CONCLUSION: Despite limitations of the data, diabetes imposes a high economic burden to individuals and society in all countries and to Latin American and the Caribbean as whole. PMID:12640472

    Remotely-sensed data and observations are providing powerful new tools for addressing climate and environment-related human health problems through increased capabilities for monitoring, risk mapping, and surveillance of parameters useful to such problems as vector-borne and infectious diseases, air and water quality, harmful algal blooms, UV (ultraviolet) radiation, contaminant and pathogen transport in air and water, and thermal stress. Remote sensing, geographic information systems (GIS), global positioning systems (GPS), improved computational capabilities, and interdisciplinary research between the Earth and health science communities are being combined in rich collaborative efforts resulting in more rapid problem-solving, early warning, and prevention in global health issues. Collaborative efforts among scientists from health and Earth sciences together with local decision-makers are enabling increased understanding of the relationships between changes in temperature, rainfall, wind, soil moisture, solar radiation, vegetation, and the patterns of extreme weather events and the occurrence and patterns of diseases (especially, infectious and vector-borne diseases) and other health problems. This increased understanding through improved information and data sharing, in turn, empowers local health and environmental officials to better predict health problems, take preventive measure, and improve response actions. This paper summarizes the remote sensing systems most useful for climate, environment and health studies of the Caribbean region and provides several examples of interdisciplinary research projects in the Caribbean currently using remote sensing technologies. These summaries include the use of remote sensing of algal blooms, pollution transport, coral reef monitoring, vectorborne disease studies, and potential health effects of African dust on Trinidad and Barbados.

    Background: In Colombia, dengue is an endemic disease and the four serotypes have been reported. Objective: To describe the frequency and severity of dengue in an area of the Colombian Caribbean (Department of Cordoba) Methods: A retrospective study was conducted. Two data sources were analysed: The database from the Direction of Health in Córdoba, and clinical registers of patients diagnosed with haemorrhagic fevers and fevers of unknown origin in reference hospitals. Results: The mean incidence of dengue between 2003-2010 was 36.5 cases/105 inhabitants (CI95%: 34.3-37.5) and adjusted for sub-reporting, could be between 178.5 and 521.6. The mean incidence of severe dengue was 4.7 cases/105 inhabitants (CI95%: 4.3-5.0). Mean mortality rate due to dengue was 0.3 cases/105 inhabitants. The fatality rate was below 1%. The mean total leukocyte count in patients with dengue was 6,181 mm3 (CI95%: 5,973-6,389) and with severe Dengue was 4,729 mm3 (CI95%: 4,220-5,238). The average platelet count in patients with Dengue was 118,793/mm3 (CI95%: 107,255-130,331) and in patients with Severe Dengue 77,655 (CI95%: 59,640-95,670). Both differences were statistically significant (p <0.05). The frequency of laboratories test per patient in patients with Dengue and severe Dengue were different. Conclusion: The department of Cordoba is a highly endemic zone of Dengue and severe Dengue in the Colombian Caribbean. Moreover, the results show significant differences between dengue and severe dengue so much in tests as in frequency of use of healthcare services. PMID:26019378

    Over 75 tsunamis have been documented in the Caribbean and Adjacent Regions during the past 500 years. Since 1500, at least 4484 people are reported to have perished in these killer waves. Hundreds of thousands are currently threatened along the Caribbean coastlines. In 2005 the Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS) was established. It recommended the following minimum seismic performance standards for the detection and analysis of earthquakes: 1) Earthquake detection within 1 minute, 2) Minimum magnitude threshold = M4.5, and 3) Initial hypocenter error of <30 km. The implementation plan of the CARIBE EWS currently includes 115 seismic stations in the Caribbean and Adjacent Regions. The NOAA National Weather Service Caribbean Tsunami Warning Program prepares and distributes monthly reports on real time and archived seismic data availability of the contributing stations at the US Tsunami Warning Centers, the Puerto Rico Seismic Network and IRIS. As of early 2014, 99 of the proposed stations are being contributed by national, regional and international seismological institutions. Recent network additions (Nicaragua, Colombia, Mexico, Cayman Islands, and Venezuela) have reduced detection threshold, time and location error throughout much of the Caribbean region and Central America. Specifically, earthquakes (>M4.0) can be detected within 1 minute throughout much of the Caribbean. The remaining exceptions to this standard for detection are portions of northern South America and Mexico. Another performance criterion is 90% data availability. Currently 60-70% of the stations meet this standard. The presentation will further report on the status of the CARIBE EWS seismic capability for the timely and accurate detection and analysis of earthquakes for tsunami warning purposes for the Caribbean and Adjacent Regions.

  9. Defining and Dividing the Greater Caribbean: Insights from the Biogeography of Shorefishes

    PubMed Central

    2014-01-01

    The Greater Caribbean biogeographic region is the high-diversity heart of the Tropical West Atlantic, one of four global centers of tropical marine biodiversity. The traditional view of the Greater Caribbean is that it is limited to the Caribbean, West Indies, southwest Gulf of Mexico and tip of Florida, and that, due to its faunal homogeneity, lacks major provincial subdivisions. In this scenario the northern 2/3 of the Gulf of Mexico and southeastern USA represent a separate temperate, “Carolinian” biogeographic region. We completed a comprehensive re-assessment of the biogeography of the Greater Caribbean by comparing the distributions of 1,559 shorefish species within 45 sections of shelf waters of the Greater Caribbean and adjacent areas. This analysis shows that that the Greater Caribbean occupies a much larger area than usually thought, extending south to at least Guyana, and north to encompass the entire Carolinian area. Rather than being homogenous, the Greater Caribbean is divided into three major provinces, each with a distinctive, primarily tropical fauna: (1) a central, tropical province comprising the West Indies, Bermuda and Central America; (2) a southern, upwelling-affected province spanning the entire continental shelf of northern South America; and (iii) a northern, subtropical province that includes all of the Gulf of Mexico, Florida and southeastern USA. This three-province pattern holds for both reef- and soft bottom fishes, indicating a general response by demersal fishes to major variation in provincial shelf environments. Such environmental differences include latitudinal variation in sea temperature, availability of major habitats (coral reefs, soft bottom shorelines, and mangroves), and nutrient additions from upwelling areas and large rivers. The three-province arrangement of the Greater Caribbean broadly resembles and has a similar environmental basis to the provincial arrangement of its sister biogeographic region, the Tropical

    2008-01-01

    The productivity and biomass of pristine coral reef ecosystems is poorly understood, particularly in the Caribbean where communities have been impacted by overfishing and multiple other stressors over centuries. Using historical data on the spatial distribution and abundance of the extinct Caribbean monk seal (Monachus tropicalis), this study reconstructs the population size, structure and ecological role of this once common predator within coral reef communities, and provides evidence that historical reefs supported biomasses of fishes and invertebrates up to six times greater than those found on typical modern Caribbean reefs. An estimated 233 000–338 000 monk seals were distributed among 13 colonies across the Caribbean. The biomass of reef fishes and invertebrates required to support historical seal populations was 732–1018 g m−2 of reefs, which exceeds that found on any Caribbean reef today and is comparable with those measured in remote Pacific reefs. Quantitative estimates of historically dense monk seal colonies and their consumption rates on pristine reefs provide concrete data on the magnitude of decline in animal biomass on Caribbean coral reefs. Realistic reconstruction of these past ecosystems is critical to understanding the profound and long-lasting effect of human hunting on the functioning of coral reef ecosystems. PMID:18348965

    This study examined demographic predictors of attitudes regarding religious coping (i.e., prayer during stressful times and look to God for support, strength and guidance) within a national sample of African American, Caribbean Blacks and non-Hispanic Whites (National Survey of American Life). The findings demonstrate significant Black-White differences in attitudes regarding religious coping with higher endorsements of religious coping among African Americans and Black Caribbeans (Caribbean Blacks). Comparisons of African Americans and Black Caribbeans revealed both similar and divergent patterns of demographic effects. For both African Americans and Black Caribbeans, women were more likely to utilize religious coping than men and married respondents were more likely than never married respondents to report utilizing prayer when dealing with a stressful situation. Further, for both groups, higher levels of education were associated with lower endorsements of the importance of prayer in dealing with stressful situations. Among African Americans only, Southerners were more likely than respondents who resided in other regions to endorse religious coping. Among Black Caribbeans, those who emigrated from Haiti were more likely than Jamaicans to utilize religious coping when dealing with a stressful episode. PMID:21048887

  13. Oceanic Remnants In The Caribbean Plate: Origin And Loss Of Related LIPs.

    NASA Astrophysics Data System (ADS)

    Giunta, G.

    2005-12-01

    The modern Caribbean Plate is an independent lithospheric entity, occupying more than 4 Mkm2 and consisting of the remnants of little deformed Cretaceous oceanic plateau of the Colombia and Venezuela Basins (almost 1 Mkm2) and the Palaeozoic-Mesozoic Chortis continental block (about 700,000 km2), both bounded by deformed marginal belts. The northern (Guatemala and Greater Antilles) and the southern (northern Venezuela) plate margins are marked by collisional zones, whereas the western (Central America Isthmus) and the eastern (Lesser Antilles) margins are represented by convergent boundaries and their magmatic arcs, all involving ophiolitic terranes. The evolutionary history of the Caribbean Plate since the Jurassic-Early Cretaceous encompasses plume, accretionary, and collisional tectonics, the evidence of which has been recorded in the oceanic remnants of lost LIPs, as revealed in: i) the MORB to OIB thickened crust of the oceanic plateau, including its un-deformed or little deformed main portion, and scattered deformed tectonic units; ii) ophiolitic tectonic units of MORB affinity and the rock blocks in ophiolitic melanges; iii) intra-oceanic, supra subduction magmatic sequences with IAT and CA affinities. The Mesozoic oceanic LIPs, from which the remnants of the Caribbean Plate have been derived, have been poorly preserved during various episodes of the intra-oceanic convergence, either those related to the original proto-Caribbean oceanic realm or those connected with two eo-Caribbean stages of subduction. The trapped oceanic plateau of the Colombia and Venezuela Basins is likely to be an unknown portion of a bigger crustal element of a LIP, similar to the Ontong-Java plateau. The Jurassic-Early Cretaceous proto-Caribbean oceanic domain consists of oceanic crust generated at multiple spreading centres; during the Cretaceous, part of this crust was thickened to form an oceanic plateau with MORB and OIB affinities. At the same time, both South and North American

    The Continuously Operating Caribbean Observational Network (COCONet) is a National Science Foundation (NSF) funded infrastructure project that stretches across the circum-Caribbean to include Central America and the northern portions of South America. Its objective is to develop a large-scale network of geodetic and atmospheric infrastructure to support a broad range of geoscience and atmospheric investigations and enable research on process-oriented science with direct relevance to geo-hazards. The network includes over 60 new and refurbished continuously operating Global Positioning System (GPS) and surface meterology stations. It will also include data from at least 60 existing stations that are being operated by one of our more than 40 regional partners. As COCONet approaches the completion of its build-out phase, it is appropriate to evaluate the activities associated with the project that facilitate capacity building. These activities include three workshops to solicit feedback from regional partners regarding science objectives, station location, and long-term network operation. COCONet graduate research fellowships have been used to support nine students, with seven from countries within the COCONet footprint. The establishment of three regional data and archive centers to foster access to data and promote free and open data standards. Lastly, two Pan American Advanced Studies Institute (PASI) workshops on topics that are central to the main goals of COCONet were also organized to engage early career scientists who are interested in working on topics that are directly relevant to the region. Perhaps the most significant effort on expanding capacity in the region is the recent deployment of a station in Camaguey, Cuba with full support from both the U.S. and Cuban governments. This presentation summarizes the activities of the COCONet project to enhance and support both the human resource development and technical capabilities within the region.

    Food security is major focus of Caribbean governments, with production being of particular concern. For the past three decades, Caribbean agriculture has been declining in relative importance, both in terms of its contribution to GDP and its share of the labour force. One of the problems Caribbean agriculture faces is the destructive impacts from weather and climate extremes. These include flood, drought, extreme temperatures, and strong winds from tropical cyclones. Other potential disasters, such as from pests and diseases attacks, are also weather and climate driven. These make weather and climate information critically important to decision-making in agriculture in the Caribbean region. In an effort to help reduce weather and climate related risks to the food security sector, The Caribbean Institute for Meteorology and Hydrology, along with its partners the Caribbean Agricultural Research and Development Institute, the World Meteorological Organization (WMO) and ten National Meteorological Services from within the Caribbean Community launched and implemented the Caribbean Agrometeorological Initiative (CAMI). From 2010 to 2013, CAMI set out to provide relevant information to farmers, and the industry in general, for decision and policy making. The project is funded by the European Union through the Science and Technology Programme of the African, Caribbean and Pacific Group of Countries' (ACP). The overarching objective of CAMI was to increase and sustain agricultural productivity at the farm level in the Caribbean region through improved applications of weather and climate information, using an integrated and coordinated approach. Currently, this is done through (i) provision of relevant climate information appropriately disseminated, (ii) predictions on seasonal rainfall and temperature, (iii) support for improved irrigation management, (iv) the development of strategically selected weather-driven pest and disease models, (v) use of crop simulation models

    The purpose of this study was to describe the perspectives of Caribbean high school students' experiences in American science classrooms. Research suggests that psychological, cultural, and socioeconomic perspectives influence the science experiences of African Americans or Blacks; the result of which is under-representation (Lewis et al., 2000). Nonetheless, what is uncertain is if these and other perspectives are similar to the science experiences of Caribbeans who also are majority black by race and rank as the 3 rd largest immigrant population in America's schools (Suarez-Orozco, 2000). Questions guiding this study were: (1) What are the perspectives of Caribbean high school students' experiences in American science classrooms? (2) What can we learn from the perspectives of Caribbean high school students' science experiences that may address issues of participation and interest; consequently, influencing the overall performance of ethnic minorities in school science? Sociocultural theory provides the framework for the analysis of the study. Four Caribbean born students in an American high school participated in this naturalistic qualitative research. A constant comparative method was used to categorize and analyze the data and uncover meaningful patterns that emerged from the four interviews and written documents. Although there were similarities between African Americans' science experiences as documented in the literature and that of Caribbeans in this study, the Caribbean participants relied on prior native experiences to dictate their perspectives of their science experiences in America. According to Caribbean students, American science high schools classrooms utilize an objective style of assessments; are characterized by a lack of teacher support; allow behavioral problems in the classroom; and function through different communication styles than the native Caribbean science classroom environment. This study implies science educators should be sensitive

    vigorously communicate results in simple and straightforward terms to foster more effective conservation and management. This and subsequent reports will focus on separate biogeographic regions in a stepwise fashion and combine all of the results for a global synthesis in the coming years. We began in the wide Caribbean region because the historical data are so extensive and to refine methods of analysis before moving on to other regions. This report documents quantitative trends for Caribbean reef corals, macroalgae, sea urchins, and fishes based on data from 90 reef locations over the past 43 tears. This is the first report to combine all these disparate kinds of data in a single place to explore how the different major components of coral reef ecosystems interact on a broadly regional oceanic scale. We obtained data from more than 35,000 ecological surveys carried out by 78 principal investigators (PIs) and some 200 colleagues working in 34 countries, states, and territories throughout the wide Caribbean region. We conducted two workshops in Panama and Brisbane, Australia to bring together people who provided the data to assist in data quality control, analysis, and synthesis. The first workshop at the Smithsonian Tropical Research Institute (STRI) in the Republic of Panama 29 April to 5 May, 2012 included scientists from 18 countries and territories to verify and expand the database and to conduct exploratory analyses of status and trends. Preliminary results based on the Panama workshop were presented to the DC Marine Community and Smithsonian Institution Senate of Scientists in May 2012 and at the International Coral Reef Symposium (ICRS) and annual ICRI meeting in Cairns, Australia in July 2012. The second workshop in Brisbane, Australia in December 2012 brought together eight coral reef scientists for more detailed data analysis and organization of results for this report and subsequent publications.

    During the Cenozoic, the areas of the Gulf of Mexico, Yucatan and Florida-Bahamas were dominated by contiguous passive margins hosting long-lasting, large carbonate platforms. In contrast, Southern Central America and the Antilles were formed by a collage of mostly oceanic terranes and arcs that reflect the complex tectonic emplacement of the Caribbean Plate between N- and S-America. In this context, carbonate palaeoenvironments were short-lived and formed either on volcanic edifices (seamounts and island arcs) or on terranes uplifted into the photic zone by collisional tectonics. Our data comes mainly from localities on the Caribbean Plate (Costa Rica, Panama and the Antilles) but includes also data from Florida, Cuba and Yucatan. The biochronologic range of most Circum-Caribbean taxa of Larger Foraminifera is currently controversial, because it is based on a large number of local and regional stratigraphic publications of the last 50 years. This work reflects a high variability of faunal composition form one area to the other, suggesting that local ranges are more likely to be controlled by changing palaeoenvironments than by biochronology. To overcome these problems, we compiled a database comprising 130 taxa from over 60 localities. Larger Foraminifera from carbonate rocks were studied in several hundred oriented thin sections and oriented sections of isolated specimens that were studied by cathodoluminescence, transmitted light microscopy and SEM for isolated and washed material. X-ray microtomography was also used to produce 3D-imaging of some forms. 87Sr/86Sr ratios were measured for age calibration on Paleocene-Eocene, Oligocene, and Late Miocene-Pliocoene fossils. Biochronologically calibrated and well-documented records of Larger Foraminifera from the literature were also incorporated into the database. Unitary Associations (UA) were calculated using Biograph and the UA-Graph software, UA represent the maximum ranges of all considered species with respect

  1. Parrotfish Size: A Simple yet Useful Alternative Indicator of Fishing Effects on Caribbean Reefs?

    There is great need to identify simple yet reliable indicators of fishing effects within the multi-species, multi-gear, data-poor fisheries of the Caribbean. Here, we investigate links between fishing pressure and three simple fish metrics, i.e. average fish weight (an estimate of average individual fish size), fish density and fish biomass, derived from (1) the parrotfish family, a ubiquitous herbivore family across the Caribbean, and (2) three fish groups of “commercial” carnivores including snappers and groupers, which are widely-used as indicators of fishing effects. We hypothesize that, because most Caribbean reefs are being heavily fished, fish metrics derived from the less vulnerable parrotfish group would exhibit stronger relationships with fishing pressure on today’s Caribbean reefs than those derived from the highly vulnerable commercial fish groups. We used data from 348 Atlantic and Gulf Rapid Reef Assessment (AGRRA) reef-surveys across the Caribbean to assess relationships between two independent indices of fishing pressure (one derived from human population density data, the other from open to fishing versus protected status) and the three fish metrics derived from the four aforementioned fish groups. We found that, although two fish metrics, average parrotfish weight and combined biomass of selected commercial species, were consistently negatively linked to the indices of fishing pressure across the Caribbean, the parrotfish metric consistently outranked the latter in the strength of the relationship, thus supporting our hypothesis. Overall, our study highlights that (assemblage-level) average parrotfish size might be a useful alternative indicator of fishing effects over the typical conditions of most Caribbean shallow reefs: moderate-to-heavy levels of fishing and low abundance of highly valued commercial species.

    Present-day (1979-2003) and future (2075-2099) simulations of mean and extreme rainfall and temperature are examined using data from the Meteorological Research Institute super-high-resolution atmospheric general circulation model. Analyses are performed over the 20-km model grid for (1) a main Caribbean basin, (2) sub-regional zones, and (3) specific Caribbean islands. Though the model's topography underestimates heights over the eastern Caribbean, it captures well the present-day spatial and temporal variations of seasonal and annual climates. Temperature underestimations range from 0.1 °C to 2 °C with respect to the Japanese Reanalysis and the Climatic Research Unit datasets. The model also captures fairly well sub-regional scale variations in the rainfall climatology. End-of-century projections under the Intergovernmental Panel on Climate Change SRES A1B scenario indicate declines in rainfall amounts by 10-20 % for most of the Caribbean during the early (May-July) and late (August-October) rainy seasons relative to the 1979-2003 baselines. The early dry season (November-January) is also projected to get wetter in the far north and south Caribbean by approximately 10 %. The model also projects a warming of 2-3 °C over the Caribbean region. Analysis of future climate extremes indicate a 5-10 % decrease in the simple daily precipitation intensity but no significant change in the number of consecutive dry days for Cuba, Jamaica, southern Bahamas, and Haiti. There is also indication that the number of hot days and nights will significantly increase over the main Caribbean basin.

  4. Building the Weather to Climate Bridge: The Caribbean Rain-Belt

    An annual bimodal rainfall cycle with peaks during the late spring and late summer is observed throughout the Intra-American Sea. A rainfall minimum occurs after the late spring early rainfall season (ERS) and is known as the "mid-summer drought" (MSD). Despite the interest in the well-studied MSD, there is a lack of research describing the onset and variability of the ERS. Rainfall during the ERS is important for Caribbean farmers as it moistens the soil after the dry season and can provide a catalyst for significant agricultural success. Contrary to the acceptance of long term regional anecdotal evidence, heavy rainfall during the ERS is not simply the result of mid-latitude fronts. Instead, heavy rainfall during the ERS arises through a series of storms or "weather events" that result from the simultaneous occurrence of two primary ingredients over the region: upper tropospheric uplift dynamics and lower tropospheric tropical moisture advection steered by the "Panama Low". A seasonal rainfall pattern emerges during the late spring in the western Caribbean, known as the Caribbean rain-belt, from the accumulated rainfall of each weather event during the ERS. During some years the Caribbean rain-belt is weak or absent, however, it remains a climatological rainfall feature that is shaped by the consistency of late spring weather events. Sub-daily rainfall time series' from the COCONet rain gauge network are used to construct the pattern of daily weather events that are then used to decompose the climatological Caribbean rain-belt. In addition, sub-daily rainfall observations are used to calculate the percent of seasonal rainfall that originates from the Caribbean rain-belt. Farmers depend on the succession of ERS weather events that shape the Caribbean rain-belt, but deadly flooding and landslides have also been recorded along the its path

    Pyrethroid pesticides are commonly used in tropical regions such as the Caribbean as household insecticides, pet sprays, and where malaria is endemic, impregnated into mosquito-repellent nets. Of particular concern is exposure during pregnancy, as these compounds have the potential to cross the placental barrier and interfere with fetal development, as was shown in limited animal studies. The objective of this study was to evaluate exposure to pyrethroids to pregnant women residing in 10 English-speaking Caribbean countries. Pyrethroid exposures were determined by analyzing five pyrethroid metabolites in urine samples from 295 pregnant women: cis-DBCA, cis-DCCA, trans-DCCA, 3-PBA, and 4-F-3-PBA. Pyrethroid metabolite concentrations in Caribbean pregnant women were generally higher in the 10 Caribbean countries than levels reported for Canadian and U.S. women. In Antigua & Barbuda and Jamaica participants the geometric mean concentrations of cis-DBCA was significantly higher than in the other nine countries together (p<0.0001 and <0.0012 respectively). For cis- and trans-DCCA, only Antigua & Barbuda women differed significantly from participants of the other nine Caribbean countries (p<0.0001). Urinary 4-F-3-PBA and 3-PBA levels were significantly higher in Antigua & Barbuda (p<0.0028 and p<0.0001 respectively) as well as in Grenada (p<0.0001 and p<0.007 respectively). These results indicate extensive use of pyrethroid compounds such as permethrin and cypermethrin in Caribbean households. In Antigua & Barbuda, the data reveals a greater use of deltamethrin. This study underscores the need for Caribbean public health authorities to encourage their populations, and in particular pregnant women, to utilize this class of pesticides more judiciously given the potentially adverse effects of exposure on fetuses and infants.

  6. Photochemical free radical production rates in the eastern Caribbean

    Potential photochemical production rates of total (NO-scavengeable) free radicals were surveyed underway (> 900 points) in the eastern Caribbean and Orinoco delta in spring and fall 1988. These data document seasonal trends and large-scale (˜ 10-1000 km) variability in the pools of sunlight-generated reactive transients, which probably mediate a major portion of marine photoredox transformations. Radical production potential was detectable in all waters and was reasonably quantifiable at rates above 0.25 nmol L-1 min-1 sun-1. Radical production rates varied from ˜ 0.1-0.5 nmol L-1 min-1 of full-sun illumination in "blue water" to > 60 nmol L-1 min-1 in some estuarine waters in the high-flow season. Qualitatively, spatiotemporal potential rate distributions strikingly resembled that of "chlorophyll" (a riverine-influence tracer of uncertain specificity) in 1979-1981 CZCS images of the region [Müller-Karger et al., 1988] at all scales. Basin-scale occurrence of greatly enhanced rates in fall compared to spring is attributed to terrestrial chromophore inputs, primarily from the Orinoco River, any contributions from Amazon water and nutrient-stimulus effects could not be resolved. A major part of the functionally photoreactive colored organic matter (COM) involved in radical formation clearly mixes without massive loss out into high-salinity waters, although humic acids may flocculate in estuaries. A similar conclusion applies over smaller scales for COM as measured optically [Blough et al., this issue]. Furthermore, optical absorption and radical production rates were positively correlated in the estuarine region in fall. These cruises demonstrated that photochemical techniques are now adequate to treat terrestrial photochemical chromophore inputs as an estuarine mixing problem on a large scale, though the ancillary data base does not currently support such an analysis in this region. Eastern Caribbean waters are not markedly more reactive at comparable salinities

    1 area of intra-Caribbean migration that has been overlooked is the "migration transition"--the transformation of rapidly modernizing societies from net labor exporters to net labor importers. This article assembles 8 case studies to 1) briefly present a spectrum of migration experiences in the Caribbean, 2) uncover some transitions under way, 3) pinpoint the forces that underlie the migration transition, and 4) point out some of the more important policy implications of labor migration reversals. The 8 island societies sampled for illustration purposes include 1) the Bahamas and the US Virgin Islands as post-migration transition societies (Zelinsky's advanced society), 2) the British Virgin Islands and the Cayman Islands as undergoing transition (Zelinsky's late transitional society), and 3) Anguilla, St. Kitts-Nevis, Turks and Caicos, and Montserrat as premigration transition societies (Zelinsky's early transitional society). Population data for the islands were derived primarily from the West Indian censuses and government statistics. These 8 historical sketches reveal certain commonalities. All are at various stages in a long-term economic restructuring to displace traditional staple crops with more income elastic, high value export services. In such societies, population growth and progress along the migration transition is an increasing function of this kind of successful export substitution. In addition, along the migration and economic transitions, such insular economies exhibit a relatively large public sector (20-30% of all activity), declining unemployment, increasing fiscal autonomy, and are committed to a development strategy remarkably similar to the "successful" model of the Bahamas and the US Virgin Islands. Cursory evidence suggests that, because of intersectoral competition for land and labor, there is an inverse relationship between farm effort/manufacturing employment and tourism intensity. This review suggests that small islands undergoing

    Background What are the determinant factors of community assemblies in the most diverse ecosystem in the ocean? Coral reefs can be divided in continental (i.e., reefs that develop on the continental shelf, including siliciclastic reefs) and oceanic (i.e., far off the continental shelf, usually on volcanic substratum); whether or not these habitat differences impose community-wide ecological divergence or species exclusion/coexistence with evolutionary consequences, is unknown. Methods Studying Caribbean octocorals as model system, we determined the phylogenetic community structure in a coral reef community, making emphasis on species coexistence evidenced on trait evolution and environmental feedbacks. Forty-nine species represented in five families constituted the species pool from which a phylogenetic tree was reconstructed using mtDNA. We included data from 11 localities in the Western Caribbean (Colombia) including most reef types. To test diversity-environment and phenotype-environment relationships, phylogenetic community structure and trait evolution we carried out comparative analyses implementing ecological and evolutionary approaches. Results Phylogenetic inferences suggest clustering of oceanic reefs (e.g., atolls) contrasting with phylogenetic overdispersion of continental reefs (e.g., reefs banks). Additionally, atolls and barrier reefs had the highest species diversity (Shannon index) whereas phylogenetic diversity was higher in reef banks. The discriminant component analysis supported this differentiation between oceanic and continental reefs, where continental octocoral species tend to have greater calyx apertures, thicker branches, prominent calyces and azooxanthellate species. This analysis also indicated a clear separation between the slope and the remaining habitats, caused by the presence or absence of Symbiodinium. K statistic analysis showed that this trait is conserved as well as the branch shape. Discussion There was strong octocoral

    Since 1998 the National Monitoring System for the Coral Reefs of Colombia (SIMAC) has monitored the occurrence of coral bleaching and diseases in some Colombian coral reefs (permanent stations at San Andres Island, Rosario Islands, Tayrona, San Bernardo Islands and Urabá). The main purpose is to evaluate their health status and to understand the factors that have been contributing to their decline. To estimate these occurrences, annual surveys in 126 permanent belt transects (10 x 2m) with different depth intervals (3-6 meters, 9-12 meters and 15-18 meters) are performed at all reef sites. Data from the 1998-2004 period, revealed that San Andrés Island had many colonies with diseases (38.9 colonies/m2), and Urabá had high numbers with bleaching (54.4 colonies/m2). Of the seven reported coral diseases studied, Dark Spots Disease (DSD), and White Plague Disease (WPD) were noteworthy because they occurred in all Caribbean monitored sites, and because of their high interannual infection incidence. Thirty five species of scleractinian corals were affected by at least one disease and a high incidence of coral diseases on the main reef builders is documented. Bleaching was present in 34 species. During the whole monitoring period, Agaricia agaricites and Siderastrea siderea were the species most severely affected by DSD and bleaching, respectively. Diseases on species such as Agaricia fragilis, A. grahamae, A. humilis, Diploria clivosa, Eusmilia fastigiata, Millepora complanata, and Mycetophyllia aliciae are recorded for first time in Colombia. We present bleaching and disease incidences, kinds of diseases, coral species affected, reef localities studied, depth intervals of surveys, and temporal (years) variation for each geographic area. This variation makes difficult to clearly determine defined patterns or general trends for monitored reefs. This is the first long-term study of coral diseases and bleaching in the Southwestern Caribbean, and one of the few long

    During a cruise with RV Meteor in the spring of 2010, magnetic measurements were carried out in the central and western Caribbean with up to six magnetic sensors deployed at the same time. These were i) a towed gradiometer consisting of two Overhauser sensors, ii) two towed vector magnetometers, and iii) two shipboard oriented vector magnetometers. While the gradiometer data provide total field magnetic anomalies free from external variations, the vector data can be analyzed with different methods in the space and wavenumber domains. In the case of the towed vector data, attitude control is challenging whereas shipboard data require a very thorough compensation for the ship's magnetic field. The data were analyzed with the goal to gain insight into the origin of the basement rocks especially of the western Caribbean. Position and strike direction of magnetic anomalies in the Columbia basin possibly hold the key to distinguish between an origin of the crust in the Pacific ocean and an alternative in situ formation between the Americas. On six long profiles in the Columbia basin and adjacent regions we find consistently strike directions of the magnetic anomalies around N100°E which seems to be incompatible with a Pacific origin of the crust. Three Project Magnet aeromagnetic vector profiles crossing the research area at different angles were analyzed with the same method and yield very similar results. In our interpretation, the crust underlying the Columbia basin formed during the Cretaceous at a roughly E-W trending spreading center between the Americas. Since the crust likely formed during the Cretaceous Superchron (C 34), the strike direction we find in our data probably does not represent typical seafloor spreading anomalies. Instead we believe it is related to changes in the intensity of the Earth's magnetic field which are known to have left correlated traces in oceanic crust formed during this period. The analysis methods we used are sensitive to intensity

    This study examines the circulation and associated monthly-to-seasonal variability in the Caribbean Sea using a regional ocean circulation model. The model domain covers the region between 99.0 and 54.0°W and between 8.0 and 30.3°N, with a horizontal resolution of 1/6°. The ocean circulation model is driven by 6-hourly atmospheric reanalysis data from the National Center for Environmental Prediction and boundary forcing extracted from 5-day global ocean reanalysis data produced by Smith et al. ( Mercator Newsletter 36:39-49, 2010), and integrated for 7 years. A comparison of model results with observations demonstrates that the regional ocean circulation model has skill in simulating circulation and associated variability in the study region. Analysis of the model results, as well as a companion model run that uses steady annual mean forcing, illustrates the role of Caribbean eddies for driving monthly-to-seasonal circulation variability in the model. It is found that vertically integrated transport between Nicaragua and Jamaica is influenced by the interaction between the density perturbations associated with Caribbean eddies and the Nicaraguan Ridge. The impact of Caribbean eddies squeezing through the Yucatan Channel is also discussed.

    Based on earlier plate reconstructions, many authors have postulated a circum-global equatorial current system flowing through the Pangea breakup, the Tethys - Atlantic - Caribbean Seaway, to explain changes in global climate during the Middle and Late Jurassic. While a Toarcian (late Early Jurassic) breakup is well constrained for the Central Atlantic, the place and timing of initial ocean crust formation between the Americas (Gulf of Mexico or Proto-Caribbean?) is still poorly constrained. Ar/Ar ages (190 to 154 Ma) in the Tinaquillo ultramafic complex (NW-Venezuela) have been interpreted as a result of initial Proto-Caribbean rifting. However, the Tinaquillo is clearly a subconinental block and the cited ages age cannot be related with breakup. The Siquisique Ophiolite (NW-Venezuela), long known for the occurrence of Bajocian-early Bathonian ammonite fragments found in interpilow sediments, has previously been interpreted as an early Proto-Caribbean remnant. However, the ammonite fragments were recovered from blocks in a Paleogene tectonic mélange, whereas the main Siquisique ophiolite body seems to be of middle Cretaceous age, based on a few Ar/Ar dates and poorly preserved middle to late Cretaceous radiolarians, which we recovered from black cherts interbedded with volcanics. The best record of Proto-Caribbean rifting and breakup is preserved in the Guaniguanico Terrane of NW-Cuba, which represents a distal Yucatan (N-American) passive margin segment telescoped by Tertiary nappe tectonics. In this terrane middle to upper Oxfordian pelagic limestones encroach on the E-MORB type El Sabalo Basalts which represent the oldest known remnants of oceanic crust clearly identifiable as Proto-Caribbean. Older, syn-rift sediments in the Proto-Caribbean and Gulf of Mexico are known to be deltaic to shallow marine detrital, and evaporitic. Although oceanic crust seemingly started to form in the early Late Jurassic (158 my), recent plate tectonic reconstructions show

    Coastal zones worldwide experience considerable population pressure and demand for a management of hazards such as tsunamis. Tsunami hazard assessment is the initial step of the management process and requires reliable information on frequency and magnitude. In areas with short historical documentation, these long-term frequency-magnitude patterns, which are best explained by inverse power-law functions, mainly rely on geological traces. According to the historical record covering the last 520 years, Caribbean tsunami hazard is demonstrated by more than 80 mostly regional or local seismically induced events. However, based on two numerical hydrodynamic models of tsunamis spawning at the Muertos Trough and the South Caribbean Deformed Belt (SCBD), two trigger scenarios only marginally considered so far, we show that pan-Caribbean tsunamis can be taken into account as well. We furthermore review more than 50 studies for possible geological evidence of tsunamis in the Caribbean including fine-grained subsurface deposits and subaerial coarse clasts, and re-evaluate their implications for tsunami hazard assessment against state-of-the-art models of tsunami deposition. Only a limited number of reliable palaeotsunami records with consistent and robust age control were identified, hampering inter-island or interregional correlation of deposits. Separating between storm and tsunami transport of solitary boulders is very difficult in most cases. Those arranged in ridges or incorporated into polymodal ridge complexes or ramparts, respectively, which line many windward coasts of the Caribbean, can mainly be attributed to long-term formation during strong storms implying the overprinting of potential tsunami signatures. The quantification of parameters of tsunami flooding based on tsunami deposits, such as flow depth, inundation distance or flow velocity, by applying inverse and forward numerical models of sediment transport is still underdeveloped in the Caribbean and needs to

    The Caribbean-South America plate boundary is characterized by tectonic transpression with oblique convergence. The ~ 20 mm/yr eastward displacement of the Caribbean plate, with respect to a fixed South America causes the plate boundary to have a dominant right-lateral strike-slip component, accommodated by the San Sebastian-El Pilar fault system. To the west, relative plate motion is complicated by the northeastward tectonic escape of the Maracaibo block along the Bocono and Santa Marta strike-slip faults, and the shortening between North and South America. The convergence rate between the Maracaibo block and the Caribbean has been estimated to be ~ 2 mm/yr. The multidisciplinary BOLIVAR project seeks to understand the complex plate interaction of the Caribbean- South American diffuse plate boundary. We hypothesize that this may be a site of continental growth by island arc accretion of the Leeward Antilles onto South America. The active-seismic component of the project, completed in June 2004, concentrated along five main onshore-offshore profiles extending from the Caribbean basin to the front of the fold and thrust belts of Venezuela. Seismic refraction data were acquired as well as coincident multi-channel seismic (MCS) lines in the offshore sections. We present results from seismic reflection and wide-angle refraction data along a 450 km-long onshore- offshore north-south striking profile at 70 degrees west longitude. Refraction data were used to develop 2-D velocity models from independent and simultaneous traveltime inversion of first arrivals and PmP reflections from 40 Ocean Bottom Seismometers (OBS) and about ~ 80 land recorders. A coincident MCS profile was processed and interpreted independently. Offshore western Venezuela the Caribbean plate is anomalously thick ~ 15 km. The velocity model from wide-angle data is well correlated with the structures interpreted in the reflection data; in particular in the upper and middle crust of the Southern

    Urban air pollution has become an increasing problem in Latin America and the Caribbean. One reason is the rapid expansion in the size of the urban population. This phenomenon is associated with an increase in the number of vehicles and in energy utilization which, in addition to industrial processes often concentrated in the cities, are the primary sources of air pollution i n Latin American cities. The air quality standards established in such countries are frequently exceeded although control programs have been implemented. The urban areas more affected by anthropogenic pollutant emissions are Sao Paulo, Brazil; Santiago, Chile; and Mexico City. In Latin America, the population of cities with high priority air pollution problems include approximately 81 million people or 26.5 percent of the total urban population of Latin America, corresponding to 30 million children (<15 years), 47 million adults (15-59 years) and 4 million elderly people ({ge}60 years) who are exposed to air pollutant levels that exceed World Health Organization (WHO) guidelines for adequate health protection.

    African dust carried to the Tropical Atlantic and Caribbean was measured during the summer months of 2015. Atmospheric particles during dust events were collected at Cape San Juan, Puerto Rico on stacked-filter units and a high-volume sampler for the fine and coarse fractions and on a low-pressure impactor for size-resolved characterization. The filter ash gravimetric method was used to determine bulk dust mass concentrations for the first time in Puerto Rico. The method was validated analyzing same filter portions at CIAM/ACAR University of Puerto Rico and at RSMAS/MAC University of Miami. Filter's extracts were analyzed for ionic species measured by ion chromatography. The water-soluble organic carbon (WSOC) was determined with a total organic carbon (TOC) analyzer. Mineral dust concentrations in Puerto Rico were compared to those reported at Miami during summer periods. Comparison between dust concentration and regional PM10 data and results on size-resolved dust concentration will also be presented.

    There is a marked difference between the perception of the sustainable development problem in the industrialized countries and that prevailing in the countries of Latin America and the Caribbean (LA&C). Whereas the industrialized countries seem concerned about the sustainability of their development in view of global climate change, developing countries in LA&C are looking for a sustainable development course that will lead them out of poverty and away from the destruction of the local environment. The industrialized countries perspective is apparent in the titles of the papers being presented at the IAEE Conference under the topic: Harmonizing Energy Policy, Environment, and Sustainable Economic Growth. A great number of titles and sessions focus on the apparent antagonism between economic growth and the environment. By environment one seems to primarily mean emissions into the air, especially greenhouse gas emissions. Probably the majority of the energy community of the industrial countries regards Latin America, on the one hand, as a holder of a large CO{sub 2} sink in danger of extinction and, on the other hand, as a potential new large contributor to greenhouse gas emissions.

    There is a pressing need for improved health care in general and emergency health care in particular throughout the Caribbean Basin. The importance of rotorcraft as an integral part of the needed system of emergency medical care in the region was investigated. Many of the larger countries in the region currently have the needed infrastructure to implement a national system of rotorcraft-based emergency medical centers within their borders. By helping to establish a system of rotorcraft based health care centers in strategic locations in the Lesser Antilles, the U.S. can assist the islands of the region by demonstrating the concept and establishing a potential training site for the other larger countries of the region. There is sufficient demand for rotorcraft based emergency health care within the Lesser Antilles to locate one center on the island of Puerto Rico and another one of the southern-most islands. With the use of fixed wing aircraft or long range helicopters, the two rotorcraft based centers could provide the region with rapid and efficient emergency health care. The superior speed and range of the XV-15 Tilt Rotor aircraft make it an attractive possibility for emergency transport and rescue in this region.

    In a project on natural hazards in the Caribbean, the following is undertaken: i) preparation of regional tsunami hazard and exposure maps to identify the region's natural disaster hot spot areas; and ii) implementation of tsunami risk assessment demonstration projects in close cooperation with the local authorities. The selected site for the demonstration project is Bridgetown, Barbados. Studies of both seismic and non-seismic tsunamigenic sources are included to provide examples of various kinds of sources with a regional distribution. The probability, location, and size of the largest credible earthquake and gravity mass flow tsunami sources are based on historical earthquake and tsunami records, large scale tectonics, geology, and topographic evaluations. The seabed displacements and mass flow dynamics related to earthquakes and mass flows, respectively, are governed by analytical calculations and statistics and used as input to numerical tsunami simulations. Numerical models for dispersive wave propagation are coupled to run-up models for nonlinear wave inundation. In the tsunami risk assessment demonstration project; local vulnerability and mortality risk maps are produced for warning purposes, public awareness, and coping capacity. The maps are based on evaluations of the tsunami inundation distance and a detailed survey of the populational pattern, buildings, and infrastructure in Bridgetown.

    The Great American Biotic Interchange has been the predominant paradigm for explaining biotic diversification in the Nearctic/Neotropical overlap or Mexican Transition Zone, which is commonly explained by the collision of the North and South American continental plates, which began in the Oligocene and fused both landmasses. In the most far-reaching cladistic biogeographical analysis of the area to date, evidence has been found supporting the existence of a remnant Caribbean region extending from eastern Mexico to southeastern USA, a hypothesis that challenges current views of the Great American Biotic Interchange and the Mexican Transition Zone. We show herein that an older terrane, which has drifted to the present day positions of Yucatan and Cuba, may be biogeographically linked to an early 'Gondwanan' biota of the Paleocene (ca. 60 Ma). The evidence indicates an east-west biotic divide in Mexico, existing before the collision and formation of Central America. The south-north division of the country, previously recognized by several authors as associated with the Great American Biotic Interchange and the Mexican Transition Zone, is of a younger age.

    The literature dealing with health and entrepreneurship has focused on developed countries. We use a sample of almost 5000 business owners and wage-workers from four Caribbean Basin countries to study this relationship. Analyses are performed using data from the Global Entrepreneurship Monitor along with the Visual Analogue Scale of the EQ-5D-5L instrument as an overall health rating. The results show that business owners are healthier than wage-workers, which is in line with the findings from studies in developed countries. Furthermore, better health is associated with a lower likelihood for fear of business failure to be a deterrent to new business formation, a greater likelihood of self-belief in having the skills to run a business, and an increased recognition of start-up business opportunities among wage-workers. These positive associations between health and entrepreneurial perceptions provide new evidence about why less healthy individuals refrain from entrepreneurship. Finally, we find that the healthiest business owners run the companies with the highest growth expectations. PMID:26794274

    The tropical shrimp genus Synalpheus includes the only eusocial marine animals. In much of the Caribbean, eusocial species have dominated the diverse fauna of sponge-dwelling shrimp in coral rubble for at least the past two decades. Here we document a recent, dramatic decline and apparent local extinction of eusocial shrimp species on the Belize Barrier Reef. Our collections from shallow reefs in central Belize in 2012 failed to locate three of the four eusocial species formerly abundant in the area, and showed steep declines in colony size and increases in frequency of queenless colonies prior to their disappearance. Concordant with these declines, several nonsocial, pair-forming Synalpheus species increased in frequency. The decline in eusocial shrimp is explained in part by disappearance of two sponge species on which they specialize. Eusocial shrimp collections from Jamaica in 2012 showed similar patterns of decline in colony size and increased queenlessness compared with prior Jamaican collections. The decline and local extinction of eusocial shrimp happened against a backdrop of changes in coral assemblages during recent decades, and may reflect changes in abundance and quality of dead coral substratum and succession of the diverse cryptic organisms living within it. These changes document potentially worrisome declines in a unique taxon of eusocial marine animals. PMID:23418429

    This essay analyses colonial nurses' travel letters, written from West Africa and the Caribbean between the turn of the century and 1920, in order to better understand the role of nurses in forming satellite versions of home. Though their primary function was to 'nurse empire' by helping to repair and maintain the bodies needed for imperial labour, nurses also contributed to written discourses supporting Britain's economic interests and political goals. Through careful consideration of primary archival material, this essay analyses the rhetorical modes that may have helped nurses gain professional and personal authority abroad. It considers nurses as moving within several kinds of imperial networks - geographical, institutional and discursive - and traces the shifts in their written self-representation according to these different contexts. In order to reform nursing, in the mid-nineteenth century Florence Nightingale defined the 'New Nurse's' ideal personality as well as her duties. Ever since, the nurse's 'character' has often been essentialised in literature and culture. As Julia Hallam observes in Nursing the Image (2000), the nurse is commonly portrayed as ministering angel, potential seductress, battleaxe or doctor's helpmate. The goal of this essay is to resist simplifying nurses' cultural significance, motivations or experiences by studying the multiple influences to which colonial nurses were subject and the shifting registers in their writing.

    Piston cores from water depths greater than 4000 m in the Venezuela Basin (Caribbean Sea) provide continuous late Pleistocene records of carbonate dissolution and accumulation. The authors examination of multiple dissolution indices indicate that, at least for the last 150,000 years, dissolution of carbonate in the Venezuela Basin has been more intense during interglacial than glacial periods, a pattern opposite to more general observations from the deep Atlantic and Gulf of Mexico. By virtue of its shallow sill depth (1815 m), the Venezuela Basin is relatively isolated from the mainstream of Atlantic thermohaline circulation, and presently is filled with homogeneous, relatively warm (3.8/sup 0/C) waters primarily derived from Upper North Atlantic Deep Water. During the last glacial, the enhanced preservation of carbonate in the Venezuela Basin suggests the presence of a less corrosive, more oxygenated water mass in the Atlantic near sill depth. However, this simple interpretations is potentially complicated by past changes in the rain of biogenic materials from surface waters to the deep basin in what must be an essentially closed system below sill depth. Their observations of increased interglacial dissolution may help to explain previously noted discrepancies in the local glacial to interglacial amplitude of delta/sup 18/O variations recorded by coccoliths and planktonic foraminifera.

    Transpressive deformation at the northern Caribbean plate boundary is accommodated mostly by two major strike-slip faults, but the amount and location of accommodation of the compressional component of deformation are still debated. We collected marine geophysical data including multibeam bathymetry and multichannel seismic reflection profiles along this plate boundary around Hispaniola, in the Jamaica Passage, and in the Gulf of Gonâve. The data set allows us to image the offshore active strike-slip faults as well as the compressional structures. We confirm that the Enriquillo-Plantain-Garden Fault Zone (EPGFZ) in the Jamaica Passage has a primary strike-slip motion, as indicated by active left-lateral strike-slip-related structures, i.e., restraining bend, asymmetrical basin, en echelon pressures ridges, and horsetail splay. Based on topographic cross sections across the EPGFZ, we image a very limited compressional component, if any, for at least the western part of the Jamaica Passage. Toward the east of the Jamaica Passage, the fault trace becomes more complex, and we identify adjacent compressional structures. In the Gulf of Gonâve, distributed folding and thrust faulting of the most recent sediments indicate active pervasive compressional tectonics. Estimates of shortening in the Jamaica Passage and in the Gulf of Gonâve indicate an increase of the compressional component of deformation toward the east, which nonetheless remains very small compared to that inferred from block modeling based on GPS measurements.

  9. Caribbean mesophotic coral ecosystems are unlikely climate change refugia.

    Deeper coral reefs experience reduced temperatures and light and are often shielded from localized anthropogenic stressors such as pollution and fishing. The deep reef refugia hypothesis posits that light-dependent stony coral species at deeper depths are buffered from thermal stress and will avoid bleaching-related mass mortalities caused by increasing sea surface temperatures under climate change. This hypothesis has not been tested because data collection on deeper coral reefs is difficult. Here we show that deeper (mesophotic) reefs, 30-75 m depth, in the Caribbean are not refugia because they have lower bleaching threshold temperatures than shallow reefs. Over two thermal stress events, mesophotic reef bleaching was driven by a bleaching threshold that declines 0.26 °C every +10 m depth. Thus, the main premise of the deep reef refugia hypothesis that cooler environments are protective is incorrect; any increase in temperatures above the local mean warmest conditions can lead to thermal stress and bleaching. Thus, relatively cooler temperatures can no longer be considered a de facto refugium for corals and it is likely that many deeper coral reefs are as vulnerable to climate change as shallow water reefs.

    The post-settlement phase of broadcast-spawned coral life histories is poorly known due to its almost complete undetectability and, hence, presumed low abundance in the field. We used lab-cultured settled polyps of two important Caribbean reef-building species with negligible larval recruitment to quantify early post-settlement survivorship (6-9 weeks) over multiple years/cohorts and differing orientation on a reef in the Florida Keys. Orbicella faveolata showed significantly and consistently better survivorship in vertical rather than horizontal orientation, but no discernable growth overall. Meanwhile, Acropora palmata showed no significant difference in survivorship between orientations, but significantly greater growth in the horizontal orientation. Both species showed significant variation in mean survivorship between cohorts of different years; 0-47 % for O. faveolata and 12-49 % for A. palmata over the observed duration. These results demonstrate wide variation in success of cohorts and important differences in the larval recruitment capacities of these two important but imperiled reef-building species.

    The phenomenon known as red tide has been a topic of great interest in that there is concern that the scale and complexity of this natural phenomenon are expanding. It is known that the benthic dinoflagellate, Gambierdiscus toxicus, produces a variety of polyether toxins that contaminate seafood and result in human illness. Maitotoxin (MTX) is one of the toxins that have been implicated in ciguatera seafood poisoning. There is a need for the development of a much broader understanding of the nature of the poisoning toxins. MTX cogeners can be difficult to isolate due to its size and chemical nature. A major goal is to obtain a purified standard of a Caribbean MTX so that more efficient assays can be developed to test seafood for the presence of toxins and thus avoid human harm. The primary goal of this project is to obtain large amounts of pure maitotoxin. The procedure described is also useful as a starting point for the purification of other toxins.

    Over the last half-century, coral diseases have contributed to the rapid decline of coral populations throughout the Caribbean region. Some coral diseases appear to be potentially infectious, yet little is known about their modes of transmission. This study experimentally tested whether dark-spot syndrome on Siderastrea siderea was directly or indirectly transmissible to neighboring coral colonies. We also tested whether open wounds were necessary to facilitate disease transmission. At the completion of the experiments, we sampled bacterial communities on diseased, exposed, and healthy coral colonies to determine whether bacterial pathogens had transmitted to the susceptible colonies. We saw no evidence of either direct or waterborne transmission of dark-spot syndrome, and corals that received lesions by direct contact with diseased tissue, healed and showed no signs of infection. There were no significant differences among bacterial communities on healthy, exposed, and diseased colonies, although nine individual ribotypes were significantly higher in diseased corals compared with healthy and exposed corals, indicating a lack of transmission. Although our experiments do not fully refute the possibility that dark-spot syndrome is infectious and transmissible, our results suggest that in situ macroscopic signs of dark-spot syndrome are not always contagious.

    The Maracaibo basin is presently located in a topographic depression on the Maracaibo block, a triangular, fault-bounded block within the Caribbean-South America plate boundary of northwestern Venezuela. Intense oil exploration over the last 50 years has produced a large amount of seismic and well data that can be used to constrain four Jurassic to Recent tectonic and depositional events that affected the region: (1). Late Jurassic rift phase and subsidence along normal faults striking north-northeast across the floor of the basin; (2) Cretaceous to early Eocene subsidence recorded by shallow to deep marine carbonate and clastic rocks that thicken from south to north and completely cover Permian rocks of the Merida arch; (3) Eocene folding, thrusting, and initial reactivation of Jurassic normal faults as convergent strike-slip and reverse faults. Eocene clastic sediments are thickest in a narrow northwest-trending foredeep on the northeastern margin of the basin; (4) Late Miocene to Recent northwest-southeast convergence is marked by continued reactivation of Jurassic normal faults as reverse and left-lateral strike-slip faults, uplift of mountain ranges bordering the basin, and deposition of up to 10 km of clastic sediment.

    Non-communicable diseases, including cancer, are overtaking infectious disease as the leading health-care threat in middle-income and low-income countries. Latin American and Caribbean countries are struggling to respond to increasing morbidity and death from advanced disease. Health ministries and health-care systems in these countries face many challenges caring for patients with advanced cancer: inadequate funding; inequitable distribution of resources and services; inadequate numbers, training, and distribution of health-care personnel and equipment; lack of adequate care for many populations based on socioeconomic, geographic, ethnic, and other factors; and current systems geared toward the needs of wealthy, urban minorities at a cost to the entire population. This burgeoning cancer problem threatens to cause widespread suffering and economic peril to the countries of Latin America. Prompt and deliberate actions must be taken to avoid this scenario. Increasing efforts towards prevention of cancer and avoidance of advanced, stage IV disease will reduce suffering and mortality and will make overall cancer care more affordable. We hope the findings of our Commission and our recommendations will inspire Latin American stakeholders to redouble their efforts to address this increasing cancer burden and to prevent it from worsening and threatening their societies.

  15. What drives microplate motion and deformation in the northeastern Caribbean plate boundary region?

    2013-12-01

    The north Caribbean plate boundary zone is a broad deformation zone with several fault systems and tectonic blocks that move with different velocities. The indentation by the Bahamas Platform (the "Bahamas collision") is generally invoked as a cause of this fragmentation. On the basis of upper mantle structure we propose that a second driver of deformation may be the western edge of the south-dipping slab along the northern Caribbean plate boundary; the westward motion of this slab edge results in a push on the Caribbean plate further west. We refer to this second mechanism for deformation as "Slab Edge Push". The motion of the North America plate relative to the Caribbean plate causes both drivers to migrate from east to west. Bahamas collision and Slab Edge Push have been operating simultaneously since the Miocene. The question is: What is the relative importance of the two mechanisms? We use mechanical finite element models that represent the two mechanisms from the Late Oligocene (30 Ma) to the Present. For the Present, both models successfully reproduce observed deformation, implying that both models are viable. Back in time the Slab Edge Push mechanism better reproduces observations. Neither mechanism successfully reproduces the observed Miocene counter-clockwise rotation of Puerto Rico. We use this rotation to tune a final model that includes fractional contributions of both mechanisms. We find that the Slab Edge Push was the dominant driver of deformation in the north Caribbean plate boundary zone since 30 Ma.

    Historical discourses about the Caribbean often chronicle West African and European influence to the general neglect of indigenous people’s contributions to the contemporary region. Consequently, demographic histories of Caribbean people prior to and after European contact are not well understood. Although archeological evidence suggests that the Lesser Antilles were populated in a series of northward and eastern migratory waves, many questions remain regarding the relationship of the Caribbean migrants to other indigenous people of South and Central America and changes to the demography of indigenous communities post-European contact. To explore these issues, we analyzed mitochondrial DNA and Y-chromosome diversity in 12 unrelated individuals from the First Peoples Community in Arima, Trinidad, and 43 unrelated Garifuna individuals residing in St. Vincent. In this community-sanctioned research, we detected maternal indigenous ancestry in 42% of the participants, with the remainder having haplotypes indicative of African and South Asian maternal ancestry. Analysis of Y-chromosome variation revealed paternal indigenous American ancestry indicated by the presence of haplogroup Q-M3 in 28% of the male participants from both communities, with the remainder possessing either African or European haplogroups. This finding is the first report of indigenous American paternal ancestry among indigenous populations in this region of the Caribbean. Overall, this study illustrates the role of the region’s first peoples in shaping the genetic diversity seen in contemporary Caribbean populations. PMID:26447794

    An international team of scientists from government agencies and universities in the United States, U.S. Virgin Islands (USVI), Trinidad & Tobago, the Republic of Cape Verde, and the Republic of Mali (West Africa) is working together to elucidate the role Saharan dust may play in the degradation of Caribbean ecosystems. The first step has been to identify and quantify the persistent organic pollutants (POPs), trace metals, and viable microorganisms in the atmosphere in dust source areas of West Africa, and in dust episodes at downwind sites in the eastern Atlantic (Cape Verde) and the Caribbean (USVI and Trinidad & Tobago). Preliminary findings show that air samples from Mali contain a greater number of pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) and in higher concentrations than the Caribbean sites. Overall, POP concentrations were similar in USVI and Trinidad samples. Trace metal concentrations were found to be similar to crustal composition with slight enrichment of lead in Mali. To date, hundreds of cultureable microorganisms have been identified from Mali, Cape Verde, USVI, and Trinidad air samples. The sea fan pathogen, Aspergillus sydowii, has been identified in soil from Mali and in air samples from dust events in the Caribbean. We have shown that air samples from a dust-source region contain orders of magnitude more cultureable microorganisms per volume than air samples from dust events in the Caribbean, which in turn contain 3-to 4-fold more cultureable microbes than during non-dust conditions.

Although archeological evidence suggests that the Lesser Antilles were populated in a series of northward and eastern migratory waves, many questions remain regarding the relationship of the Caribbean migrants to other indigenous people of South and Central America and changes to the demography of indigenous communities post-European contact. To explore these issues, we analyzed mitochondrial DNA and Y-chromosome diversity in 12 unrelated individuals from the First Peoples Community in Arima, Trinidad, and 43 unrelated Garifuna individuals residing in St. Vincent. In this community-sanctioned research, we detected maternal indigenous ancestry in 42% of the participants, with the remainder having haplotypes indicative of African and South Asian maternal ancestry. Analysis of Y-chromosome variation revealed paternal indigenous American ancestry indicated by the presence of haplogroup Q-M3 in 28% of the male participants from both communities, with the remainder possessing either African or European haplogroups. This finding is the first report of indigenous American paternal ancestry among indigenous populations in this region of the Caribbean. Overall, this study illustrates the role of the region's first peoples in shaping the genetic diversity seen in contemporary Caribbean populations. PMID:26447794

    The Muertos Trough in the northeast Caribbean has been interpreted as a subduction zone from seismicity, leading to infer a possible reversal subduction polarity. However, the distribution of the seismicity is very diffuse and makes definition of the plate geometry difficult. In addition, the compressive deformational features observed in the upper crust and sandbox kinematic modeling do not necessarily suggest a subduction process. We tested the hypothesized subduction of the Caribbean plate’s interior beneath the eastern Greater Antilles island arc using gravity modeling. Gravity models simulating a subduction process yield a regional mass deficit beneath the island arc independently of the geometry and depth of the subducted slab used in the models. This mass deficit results from sinking of the less dense Caribbean slab beneath the lithospheric mantle replacing denser mantle materials and suggests that there is not a subducted Caribbean plateau beneath the island arc. The geologically more realistic gravity model which would explain the N-S shortening observed in the upper crust requires an overthrusted Caribbean slab extending at least 60 km northward from the deformation front, a progressive increase in the thrusting angle from 8° to 30° reaching a maximum depth of 22 km beneath the insular slope. This new tectonic model for the Muertos Margin, defined as a retroarc thrusting, will help to assess the seismic and tsunami hazard in the region. The use of gravity modeling has provided targets for future wide-angle seismic surveys in the Muertos Margin.

    A reconnaissance review of reflection-seismic sections from the Caribbean, together with limited information derived from dredged rocks, sediment cores, and drillholes, yields or contributes to first-order conclusions regarding the tectonic history of the water-covered Caribbean. Broadly speaking, tectonic episodes for which there is some evidence are: (1) late Cenozoic convergence and accretion along deformed continental or island margins off Panama, Colombia/Venezuela, and Hispaniola/Puerto Rico; (2) late Cenozoic generation of oceanic crust within the Cayman Trough; (3) late Cenozoic secondary deformation along the Caribbean-North American plate boundary zone, in the form of small pull-apart basins, transcurrent faults, tensional rift basins, and compressional features; (4) late Cenozoic slow disintegration of the western part of the Caribbean plate; (5) Cenozoic rift-basin formation on the upper Nicaraguan rise; (6) early Cenozoic or late Cretaceous opening of the Yucatan Basin; (7) late Cretaceous through early Cenozoic island arc formation; and (8) late Cretaceous and earlier emplacement of flow basalts in the northwestern Venezuelan Basin and possibly beneath large areas of the Caribbean. There is no evidence that except along their active margins, the Venezuelan Basin, Beata Ridge, Colombian Basin, and Nicaraguan rise areas have been sites for large-scale relative movements which created or destroyed plate material since late Cretaceous time - or earlier.

  13. Changes in Late Cretaceous-Quaternary Caribbean plate motion directions inferred from paleostress measurements from striated fault planes

    NASA Astrophysics Data System (ADS)

    Batbayar, K.; Mann, P.; Hippolyte, J.

    2013-12-01

    We compiled paleostress analyses from previous research works collected at 591 localities of striated fault planes in rocks ranging in age from Late Cretaceous to Quaternary in the circum-Caribbean and Mexico. The purpose of the study is to quantify a progressive clockwise rotation of the Caribbean plate during its Late Cretaceous to recent subduction of the Proto-Caribbean seaway. Paleostress analysis is based on the assumption that slickenside lineations indicate both the direction and sense of maximum resolved shear stress on that fault plane. We have plotted directions of maximum horizontal stress onto plate tectonic reconstructions of the circum-Caribbean plate boundaries and infer that these directions are proxies for paleo-plate motion directions of the Caribbean plate. Plotting these stress directions onto reconstructions provided a better visualization of the relation of stress directions to blocks at their time of Late Cretaceous to recent deformation. Older, more deformed rocks of Late Cretaceous to Eocene ages yield a greater scatter in derived paleostress directions as these rocks have steeper dips, more pervasive faulting, and were likely affected by large rotations as known from previous paleomagnetic studies of Caribbean plate margins. Despite more scatter in measurements from older rock units, four major events that affected the Caribbean plate and the Great Arc of the Caribbean (GAC) are recognizable from changing orientations of stress directions: 1) Late Cretaceous collision of the GAC with southern Mexico and Colombia is consistent with NE directions of maximum compression in rocks of this age range in southern Mexico and EW directions in Colombia as the GAC approached the Proto-Caribbean seaway; 2) Paleocene-Eocene collision of the GAC with the Bahamas platform in Cuba and Hispaniola and with the South American plate in Venezuela is consistent with CW rotations of stress directions in rocks of these ages in the northern Caribbean and CCW

    2015-01-01

    As part of a study on Marphysa de Quatrefages, 1865 from the Grand Caribbean, three species regarded as junior synonyms of M. sanguinea (Montagu, 1913) were studied to clarify their taxonomic status. The examination of type and additional materials collected in the southern Gulf of Mexico and the Mexican Caribbean regions, allowed us to clarify that M. acicularum Webster, 1884, M. nobilis Treadwell, 1917 and M. viridis Treadwell, 1917 are distinct species. Therefore, the three species were redescribed and some important morphological features such as maxillary apparatus, shape of parapodial lobes, shape of ventral cirri and pectinate chaetae, among others, were described and evaluated. Furthermore, we consider that previous records of M. sanguinea for the Grand Caribbean are doubtful and it is necessary to reassess those specimens to clarify their taxonomic identity. PMID:25781729

    This study explores the relationship of family and demographic factors to the frequency of receiving emotional support and the frequency of engaging in negative interactions with family members (i.e., criticism, burden, and being taken advantage of). The study uses the ambivalence framework and data from the National Survey of American Life, a national sample of African Americans and Caribbean Blacks (Caribbean Blacks). Overall, no significant differences were found between African Americans and Caribbean Blacks in the frequency of emotional support or negative interaction; several significant correlates (e.g., age, family closeness) were found for both groups. However, a number of unique associations were also demonstrated (e.g., marital status, frequency of family contact), indicating differences in the ways that these variables operate within the two populations. These and other findings are discussed in relation to the ambivalence framework and subgroup differences in family phenomena within the Black population. PMID:26617426

  16. A Rossby whistle: A resonant basin mode observed in the Caribbean Sea

    2016-07-01

    We show that an important source of coastal sea level variability around the Caribbean Sea is a resonant basin mode. The mode consists of a baroclinic Rossby wave which propagates westward across the basin and is rapidly returned to the east along the southern boundary as coastal shelf waves. Almost two wavelengths of the Rossby wave fit across the basin, and it has a period of 120 days. The porous boundary of the Caribbean Sea results in this mode exciting a mass exchange with the wider ocean, leading to a dominant mode of bottom pressure variability which is almost uniform over the Grenada, Venezuela, and Colombia basins and has a sharp spectral peak at 120 day period. As the Rossby waves have been shown to be excited by instability of the Caribbean Current, this resonant mode is dynamically equivalent to the operation of a whistle.

    2014-01-01

    Based on a wide range of primary materials, including WHO reports and Colonial Office correspondence, this article examines the UNICEF/WHO-funded mass BCG campaigns that were carried out in seven Caribbean colonies between 1951 and 1956. It explores the reasons behind them, their nature and aftermath and also compares them to those in other non-European countries and discusses them within a context of decolonisation. In doing so, it not only adds to the scholarship on TB in non-European contexts, which had tended to focus on Africa and Asia, but also to the relatively new field of Caribbean medical history and the rapidly expanding body of work on international health, which has paid scant attention to the Anglophone Caribbean and the pre-independence period.

    The purpose of this study was to examine the correlates of watching religious television programs and listening to religious radio programs. Data are taken from the National Survey of American Life, a nationally representative study of African Americans, Black Caribbeans, and non-Hispanic Whites. Several significant findings were noted. Both African Americans and Black Caribbeans watched religious television programs and listened to religious radio programs significantly more frequently than non-Hispanic whites. These differences in electronic religious media consumption were particularly large, especially listening to religious radio programming. Among African Americans and Black Caribbeans, several significant demographic differences in frequency of consuming religious programming (e.g., age, gender, region, marital status, immigration status) emerged. Lastly, our analysis found that consuming electronic religious programming did not substitute for attending church service but, instead, complemented weekly service attendance. PMID:26045698

    Seagrasses comprise 78 species and are rarely invasive. But the seagrass Halophila stipulacea, firstly recorded in the Caribbean in the year 2002, has spread quickly throughout the region. Previous works have described this species as invasive in the Caribbean, forming dense mats that exclude native seagrass species. During a reconnaissance field survey of Caribbean seagrass meadows at the islands of Bonaire and Sint Maarten in 2013, we observed that this species was only extremely dense at 5 out of 10 studied meadows. Compared to areas with sparse growth of H. stipulacea, these dense meadows showed consistently higher nutrient concentrations, as indicated by higher leaf tissue N contents of the seagrass Thalassia testudinum (dense when C:N < 22.5) and sediments (dense when %N > 11.3). Thus, the potential invasiveness of this non-native seagrass most likely depends on the environmental conditions, especially the nutrient concentrations.

    2016-01-01

    Introduction: There have been no previous reports on the anatomic variations that exist on inferior surface of the liver in Caribbean populations. This information is important to optimize radiology and hepatobiliary surgical services in the region. Methods: Two investigators independently observed 69 cadaveric dissections over five years and described the variations in surface anatomy. Results: In this population 88% of cadaveric livers had conventional hepatic surface anatomy. However, 12% had accessory sulci present on the visceral surface of the liver, with a 7:1 male preponderance. When present, there was 100% correlation between the presence of Rouvière’s sulcus and the right branch of portal pedicle. Conclusion: Abnormal surface anatomy is present in 12% of unselected specimens in this Caribbean population. Interventional radiologists and hepatobiliary surgeons practicing in the Caribbean must be cognizant of these differences in order to minimize morbidity during invasive procedures. PMID:27493591

  1. Marine climate influences on interannual variability of tropical cyclones in the eastern Caribbean: 1979-2008

    NASA Astrophysics Data System (ADS)

    Jury, Mark R.

    2015-04-01

    Interannual variability of tropical cyclones (TCs) in the eastern Caribbean is studied using MIT-Hurdat fields during the July-October season from 1979 to 2008. TC intensity shows local climate sensitivity particularly for upper ocean currents, salinity and mixed-layer depth, and 200-850 mb wind shear. Remote influences from the Southern Oscillation, Saharan dust, and the South American monsoon are also identified as important. Ocean currents diminish along the coast of South America, so interbasin transfer between the North Brazil and Caribbean Currents declines in seasons of frequent and intense TCs. This is related to a dipole pattern in the sea surface height formed mainly by reduced trade wind upwelling northeast of Venezuela. A low-salinity plume from the Orinoco River spreads across the eastern Caribbean. It is the weaker currents and shallower mixed layer that conspire with surplus heat to build thermodynamic energy available for TC intensification.

    The Caribbean has shown changes in its climate (temperature and rainfall) as a result of urbanisation, population growth and industrialisation. The climatic changes have implications for the emergence and re- emergence of rodent-borne diseases such as leptospirosis. In this paper wavelet analysis is used to investigate the relationship between the incidence of leptospirosis in the Caribbean and climate variables such as temperature and precipitation. Wavelet analysis takes into account characteristics unique to climate and epidemiological data which other spectral techniques failed to do. The analysis reveals 2-3 year periodic signals in both the wavelet power spectrum and wavelet coherency. There is also a correlation between incidence of leptospirosis and late season Caribbean rainfall.

  3. The Influence of Spirituality on Health Behaviors in an Afro-Caribbean Population.

    Marshall, Jacqueline; Archibald, Cynthia

    2015-01-01

    Spirituality is an integral part of the Afro-Caribbean experience. This study explored spirituality's influence on health in a church-going Afro-Caribbean population in order to further develop the concept of Spiritually-Guided Health risk Interception (SGHRI). Using a naturalistic approach, ten (10) members of local Pentecostal churches including ministry leaders, were interviewed. Items from the Spiritual Health Locus of Control scale (SHLC) guided the sessions. Content analysis was used to examine the data, and three themes emerged: compassion for service, divine authority, and shared responsibility. The findings of this study suggested that Afro Caribbean church-goers are fervent in their spirituality and dedication to social services provided by the church. While they rely on church leaders for guidance in health matters, recognition of personal role in health promotion was acknowledged. This valuable resource may be used to combine the fundamental principles associated with their spiritual practices and with health risk interceptions. PMID:26336662

    2010-01-01

    The Caribbean has the highest HIV rates outside of sub-Saharan Africa. In recent decades, tourism has become the most important Caribbean industry. Studies suggest that tourism areas are epicenters of demographic and social changes linked to HIV risk, such as transactional sex, elevated alcohol and substance use, and internal migration. Despite this, no formative HIV-prevention studies have examined tourism areas as ecologies that heighten HIV vulnerability. HIV/AIDS research needs to place emphasis on the ecological context of sexual vulnerability in tourism areas and develop multilevel interventions that are sensitive to this context. From our review and integration of a broad literature across the social and health sciences, we argue for an ecological approach to sexual health in Caribbean tourism areas, point to gaps in knowledge, and provide direction for future research.

    2014-01-01

    In 2013, the first autochthonous cases of the chikungunya virus (CHIKV) were reported on the Caribbean island of Saint Martin. The chikungunya virus has since become endemic in the Caribbean due to autochthonous transmission. In the presence of fever and joint symptoms in any traveller returning from the Caribbean, CHIKV should be considered. Although symptoms resemble those of dengue fever, the course of chikungunya is milder. Chikungunya much more commonly causes chronic joint pain. Laboratory tests for the chikungunya virus may give false positive results due to cross reactions with closely related viruses, so taking a full disease and travel history from the patient is necessary in order to interpret these test results correctly. There is no specific treatment for the chikungunya virus. A correct diagnosis can prevent unnecessary additional tests and unjustified treatment. The chikungunya virus can be prevented by the use of insect-repelling substances, nets and air-conditioning. PMID:25269640

  6. Composite focal mechanism for microearthquakes along the northeastern border of the Caribbean plate

    SciTech Connect

    Frankel, A.

    1982-05-01

    Seismograms from a local seismic network in the Virgin Islands portion of the northeastern Caribbean are used to determine a composite focal mechanism for 26 microearthquakes along the North America--Caribbean plate boundary. Only one nodal plane of the focal mechanism could be constrained from P-wave first motion data alone. P/SV amplitude ratios observed for these events were compared to theoretical amplitude ratios calculated for different focal mechanisms. This procedure constrained the dip of the second nodal plane to be shallower than about 50/sup 0/, ruling out the possibility of a transform fault in this portion of the plate boundary. The resulting focal mechanism indicates that oblique underthrusting of the North American plate beneath the Caribbean plate occurs in the area. This oblique motion is accommodated along a thrust plane that dips at a relatively shallow angle beneath the Virgin Islands platform.

  7. Early implications of the COCONet GPS velocity field for studies of plate and microplate motions in the Caribbean

    NASA Astrophysics Data System (ADS)

    DeMets, C.

    2013-05-01

    Now entering their 3rd decade, GPS measurements in the Caribbean region have been used to study a wide range of tectonic topics such as the movement of the Caribbean plate relative to North and South America, earthquake cycle effects along the seismically hazardous Caribbean plate boundary faults, and microplate interactions along the complexly deforming Caribbean plate boundaries. The construction of COCONet stands out as the most significant-ever one-time advance in GPS-MET infrastructure in the Caribbean region due to its standardized GPS-MET equipment, its open access to real-time data, and its expansion of coverage relative to pre-existing GPS stations. In this talk, I will show an up-to-date Caribbean region velocity field derived using the most recent version of GIPSY software (release 6.1), the latest satellite orbit products, single-station ambiguity resolution, and a consistent realization of the Caribbean plate reference frame. Consisting of several hundred site velocities, the new velocity field clearly defines how the crust responds to east-to-west changes in the geometry of the Caribbean-North America plate boundary, including the profound effect of the oblique collision zone between the Bahama platform and northern edge of the Caribbean plate. I will discuss implications of the still-maturing COCONet GPS velocities for ongoing studies of Caribbean plate motion and plate rigidity and will also discuss applications of COCONet velocities for testing recently published kinematic estimates for the movements of the Gonave, Puerto Rico, Hispaniola, and southern Jamaica microplates.

    2010-01-01

    Background Regional genetic connectivity models are critical for successful conservation and management of marine species. Even though rocky shore invertebrates have been used as model systems to understand genetic structure in some marine environments, our understanding of connectivity in Caribbean communities is based overwhelmingly on studies of tropical fishes and corals. In this study, we investigate population connectivity and diversity of Cittarium pica, an abundant rocky shore trochid gastropod that is commercially harvested across its natural range, from the Bahamas to Venezuela. Methodology/Principal Findings We tested for genetic structure using DNA sequence variation at the mitochondrial COI and 16S loci, AMOVA and distance-based methods. We found substantial differentiation among Caribbean sites. Yet, genetic differentiation was associated only with larger geographic scales within the Caribbean, and the pattern of differentiation only partially matched previous assessments of Caribbean connectivity, including those based on larval dispersal from hydrodynamic models. For instance, the Bahamas, considered an independent region by previous hydrodynamic studies, showed strong association with Eastern Caribbean sites in our study. Further, Bonaire (located in the east and close to the meridional division of the Caribbean basin) seems to be isolated from other Eastern sites. Conclusions/Significance The significant genetic structure and observed in C. pica has some commonalities in pattern with more commonly sampled taxa, but presents features, such as the differentiation of Bonaire, that appear unique. Further, the level of differentiation, together with regional patterns of diversity, has important implications for the application of conservation and management strategies in this commercially harvested species.

    Outcrops of volcanic-hypabyssal rocks in Trinidad document the opening of the proto-Caribbean seaway during Jurassic-Cretaceous break-up of the Americas. The San Souci Group on the northern coast of Trinidad comprises the San Souci Volcanic Formation (SSVF) and passive margin sediments of the ~ 130-125 Ma Toco Formation. The Group was trapped at the leading edge of the Pacific-derived Caribbean Plate during the Cretaceous-Palaeogene, colliding with the para-autochthonous margin of Trinidad during the Oligocene-Miocene. In-situ U-Pb ion probe dating of micro-zircons from a mafic volcanic breccia reveal the SSVF crystallised at 135.0 ± 7.3 Ma. The age of the SSVF is within error of the age of the Toco Formation. Assuming a conformable contact, geodynamic models indicate a likely origin for the SSVF on the passive margin close to the northern tip of South America. Immobile element and Nd-Hf radiogenic isotope signatures of the mafic rocks indicate the SSVF was formed by ≪10% partial melting of a heterogeneous spinel peridotite source with no subduction or continental lithospheric mantle component. Felsic breccias within the SSVF are more enriched in incompatible elements, with isotope signatures that are less radiogenic than the mafic rocks of the SSVF. The felsic rocks may be derived from re-melting of mafic crust. Although geochemical comparisons are drawn here with proto-Caribbean igneous outcrops in Venezuela and elsewhere in the Caribbean more work is needed to elucidate the development of the proto-Caribbean seaway and its rifted margins. In particular, ion probe dating of micro-zircons may yield valuable insights into magmatism and metamorphism in the Caribbean, and in altered basaltic terranes more generally.

    Background: Caribbean women have the highest human immunodeficiency virus (HIV) infection rates among women in the Americas; however, their self-assessment of HIV risk is alarmingly low. This reflects a low perceived risk for HIV. English-speaking Caribbean countries are typically understudied in this area. It is important for health researchers and practitioners to understand the underlying perceptions of women who are now driving this epidemic. This review discusses and critiques the published literature that examines Caribbean women's perceived HIV risks. Methods: Medline, PsycINFO, Global Health, Women's Studies International, and Academic Search Complete databases were searched using various combinations of the following keywords: Caribbean, women, HIV, STD, AIDS, risk, perceived risk, risk perception, and sex. Searches were restricted to English. A total of 69 peer-reviewed studies were obtained from the initial 239 records. The reviewer screened the peer-reviewed articles and excluded 50 studies that did not directly assess perceived HIV risks in Caribbean women. An additional 12 studies were excluded based on the following exclusion criteria: an undetermined proportion or more than 50% of the sample consisted of pregnant women, sex workers, drug users, Latinas, and/or people living with HIV/AIDS. Results: Seven studies on perceived HIV risk in Caribbean women were reviewed. Jamaican women were the most represented ethnic demographic (43%). All studies assessed perceived risk as a subset of HIV psychosocial factors, sexual-risk behaviors, HIV knowledge, attitudes, and beliefs. Four studies used cross-sectional research design and two studies used qualitative methodology. Only one study described items used to measure perceived risk. General findings indicate overall perceptions of invulnerability among Caribbean women, despite high sexual-risk behaviors. Conclusions: Published studies that specifically assess Caribbean women's HIV risk perceptions are

    Purpose The purpose of this study was to discover ways to tailor health care interventions to fit the cultural identity of a minority group of people in order to reduce health disparity. Design/Analysis A naturalistic approach was used to interview four self-identified Afro-Caribbean Americans about their experiences of living on the margin. Through content analysis, categories emerged from the transcription revealed embracing, non-entitlement, enduring disrespect, and caring for self. Conclusion Afro-Caribbean Americans have strong values, healthy intentions, and appropriate attitude which are critical combinations for successfully tailoring interventions. Implications are discussed. PMID:22288207

    We report herein the metallurgical and acoustical characterization of hydroformed 304 stainless steel, Caribbean pans. These pans were fully tuned to chromatic tones and compared to a manufactured, low-carbon, Caribbean steel pan standard. Hydroformed platforms had a Vickers microindentation hardness of HV 345, which was reduced by annealing during pan fabrication to HV 270. Skirts welded to the hydroformed head had a microindentation hardness of HV 440. Microstructural characterization by light optical metallography and transmission electron microscopy illustrated microstructures (including grain structures) characteristic of these pan microindentation hardnesses.

    Based on the North American Regional Reanalysis and the ECMWF 40-Year Reanalysis, the Caribbean region shows a maximum greater than 11 m/s in easterly zonal winds at 925 mb in July and a secondary maximum in February that roughly cover the area from 70°W to 80°W and from 12°N to 16°N. This area is used to define an index of this Caribbean Low-Level Jet (CALLJ) and its variability based on zonal wind anomalies at 925 mb. The annual and interannual variability of the Caribbean Low-Level Jet (CALLJ) is studied for the period 1979-2001. The maximum in boreal summer is related to the combined effects of a northward sea level pressure (SLP) gradient and a northward temperature gradient. The CALLJ index has greater interannual variability in August and September related to large-scale anomalous climate patterns in sea surface temperature (SST) and SLP. A strengthening of the easterly CALLJ is concurrent with an anomalous inter-basin SST gradient with a warmer tropical Pacific and a cooler tropical Atlantic. In the Caribbean Sea a strengthening (weakening) of the CALLJ is related to cooler (warmer) waters along the northern coast of South America due to stronger (weaker) upwelling. Also, a strengthening of the CALLJ is concurrent with low SLP over the tropical Pacific and high SLP over the tropical Atlantic. A south-north SLP gradient across the Caribbean and Central America is highly correlated with the variability of the CALLJ. Related to the CALLJ variability there are anomalies of vertical wind shear and moisture flux convergence that affect the convective precipitation intensity over the Caribbean and Central America. An increase in the easterly flow of the CALLJ is related to less precipitation over large areas of the Caribbean, Central America and the eastern tropical north Pacific. Composites of Atlantic hurricanes for the extreme events of the CALLJ show a distinctive pattern of tropical cyclone activity over the Caribbean, the tropical North Atlantic and in

    We present a a leaky, resonant Rossby basin mode in the Caribbean Sea, excited by instability of the Caribbean Current. The mode is seen at the surface as westward-propagating Rossby waves with period 120 days, but it is most distinctive in ocean bottom pressure where it is seen in both observations and in a wide variety of ocean models. This bottom pressure mode is a product of the leakiness of the basin, which allows for mass exchange with the surrounding ocean. The mode is found to dominate sea level variability on parts of the South American coast.

    Sociality has evolved in a wide range of animal taxa but infectious diseases spread rapidly in populations of aggregated individuals, potentially negating the advantages of their social interactions. To disengage from the coevolutionary struggle with pathogens, some hosts have evolved various forms of “behavioral immunity”; yet, the effectiveness of such behaviors in controlling epizootics in the wild is untested. Here we show how one form of behavioral immunity (i.e., the aversion of diseased conspecifics) practiced by Caribbean spiny lobsters (Panulirus argus) when subject to the socially transmitted PaV1 virus, appears to have prevented an epizootic over a large seascape. We capitalized on a "natural experiment" in which a die-off of sponges in the Florida Keys (USA) resulted in a loss of shelters for juvenile lobsters over a ~2500km2 region. Lobsters were thus concentrated in the few remaining shelters, presumably increasing their exposure to the contagious virus. Despite this spatial reorganization of the population, viral prevalence in lobsters remained unchanged after the sponge die-off and for years thereafter. A field experiment in which we introduced either a healthy or PaV1-infected lobster into lobster aggregations in natural dens confirmed that spiny lobsters practice behavioral immunity. Healthy lobsters vacated dens occupied by PaV1-infected lobsters despite the scarcity of alternative shelters and the higher risk of predation they faced when searching for a new den. Simulations from a spatially-explicit, individual-based model confirmed our empirical results, demonstrating the efficacy of behavioral immunity in preventing epizootics in this system.

  16. Recruitment and Resilience of a Harvested Caribbean Octocoral

    Disturbance events are an important component of the ecology of coral reefs and increasingly frequent disturbances coupled with a lack of population resilience may contribute to changes in the structure of coral reef communities. The harvest of the Caribbean octocoral Antillogorgia elisabethae provides an opportunity to explore the relationship between adult abundance and recruitment and the manner in which recruitment contributes to the resilience of local populations. Recruitment of A. elisabethae was monitored in 20, 1-m2 quadrats at 8 sites along the southern edge of the Little Bahama Bank from 2004 through 2007. A. elisabethae has been harvested in The Bahamas for over fifteen years and all of the sites had been harvested three times, including a harvest during the course of the study. Abundances of adult colonies at those sites as well as a location that had not been harvested were also determined. Recruitment was highly variable, differing between sites, transects within sites, and, depending on the site, between years. Recruitment was best correlated with adult abundance averaged across the surrounding site. Regression analyses suggest abundance on smaller scales had only small effects on recruitment. The effects of the harvesting were site specific ranging from a 38 to 67% reduction in the density of mature colonies. The sites with the most abundant A. elisabethae continued to have the highest abundances after harvesting and there was no significant difference in recruitment before and after harvesting. Population size-structure at 6 of 8 sites that have been harvested multiple times exhibited an overall depletion in small colonies suggesting long term suppression of recruitment and declining populations. Severe depression of adult abundances coupled with local recruitment can create a negative feedback and lead to the decline of local populations. Populations that are dependent on self-recruitment are not resilient to large disturbance events. PMID

    Daily sea surface temperature (SST) data from the Advanced Very High Resolution Radiometer (AVHRR) database with ∼4 km of spatial resolution were analyzed for the period 1985-2009 in the Colombian Basin using harmonic and empirical orthogonal function (EOF) analysis. The data were compared with observational records in the Rosario Island National Park at 10 m depth (T10) from March 2003 to August 2005. SST values were higher than T10 from June to October (rainy season), but similar from December to February (dry season); both data sets have similar coefficient of variation. The mean SST distribution varies spatially, with minimum SST values in the coastal zone of La Guajira Peninsula and maximum values in the Darien and Mosquitos Gulfs. The seasonal variability explains up to 75% of the total variability in La Guajira, a high value compared with 40% in the Mosquitos Gulf. The most important feature of the splitting of SST variation into annual and semiannual harmonics in La Guajira is the relationship between their amplitudes. These are of the same order, which is not common in other ocean zones, where the semiannual component is only a small fraction of the annual dominated by the solar warming. The river water discharge, highest from August to November, produces low density surface water, reduces vertical mixing and limits the absorption of solar radiation to a thin surface layer, explaining the discrepancy between SST and T10 in the rainy season. The decomposition of the SST in EOFs indicated that the dominant mode of the basin is a uniform interannual variation in phase with the North Tropical Atlantic Index. The second mode, representing the variability of the Guajira upwelling, covaried strongly with the second mode of wind stress curl. The third mode reflected the role of the vertical atmospheric circulation cell associated with the Caribbean Low Level Jet off Central America.

  18. A screening for antimicrobial activities of Caribbean herbal remedies

    2013-01-01

    Background The TRAMIL program aims to understand, validate and expand health practices based on the use of medicinal plants in the Caribbean, which is a “biodiversity hotspot” due to high species endemism, intense development pressure and habitat loss. The antibacterial activity was examined for thirteen plant species from several genera that were identified as a result of TRAMIL ethnopharmacological surveys or were reported in ethnobotanical accounts from Puerto Rico. The aim of this study was to validate the traditional use of these plant species for the treatment of bacterial infections, such as conjunctivitis, fever, otitis media and furuncles. Methods An agar disc diffusion assay was used to examine five bacterial strains that are associated with the reported infections, including Staphylococcus saprophyticus (ATCC 15305), S. aureus (ATCC 6341), Escherichia coli (ATCC 4157), Haemophilus influenzae (ATCC 8142), Pseudomonas aeruginosa (ATCC 7700) and Proteus vulgaris (ATCC 6896), as well as the fungus Candida albicans (ATCC 752). The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were determined for each of the extracts that showed inhibitory activity. Results The decoctions of Pityrogramma calomelanos, Tapeinochilus ananassae, and Syzygium jambos, as well as the juice of Gossypium barbadense, showed > 20% growth inhibition against several bacteria relative to the positive control, which was the antibiotic Streptomycin. Extracts with the best antimicrobial activities were S. jambos that showed MIC = 31 μg/mL and MBC = 1.0 mg/mL against P. vulgaris and T. ananassae that showed MIC = 15 μg/mL against S. aureus. Conclusion This report confirms the traditional use of P. calomelanos for the treatment of kidney infections that are associated with stones, as well as the antimicrobial and bactericidal effects of T. ananassae against P. vulgaris and S. saprophyticus and the effects of S. jambos against S

    Sponges are common sessile benthic suspension feeders that play a critical role in carbon and nitrogen cycling within reef ecosystems via their filtration capabilities. Due to the contribution of sponges in benthic-pelagic coupling, it is critical to assess factors that may affect their role in the healthy function of coral reefs. Several factors can influence the rate at which an individual sponge pumps water, including body size, environmental conditions, mechanical blockage, and reduction of inhalant pores (ostia). Symbiotic zoanthid colonization is a common occurrence on Caribbean sponges, and the presence of zoanthids on the surface of a sponge may occlude or displace the inhalant ostia. We quantified pumping rates of the giant barrel sponge, Xestospongia muta ( N = 22 uncolonized, 37 colonized) and the common vase sponge, Niphates digitalis ( N = 21 uncolonized, 17 colonized), with and without zoanthid symbionts, Parazoanthus catenularis and Parazoanthus parasiticus, respectively. For X. muta, biovolume-normalized pumping rates of individuals colonized by zoanthids were approximately 75 % lower than those of uncolonized sponges. Moreover, colonization with zoanthids was related to a difference in morphology relative to uncolonized individuals: Colonized sponges exhibited an osculum area to biovolume ratio that was nearly 65 % less than uncolonized sponges. In contrast, the presence of zoanthids on N. digitalis resulted in only a marginal decrease in pumping rates and no detectable difference in morphology. The difference in zoanthid effects between X. muta and N. digitalis is likely due to the differences in wall thickness and architecture between the two species. The probable cause of reduced pumping in affected sponges is occupation of the sponge surface that leads to blockage or displacement of inhalant ostia. To partially test this hypothesis, zoanthid colonization on specimens of X. muta was simulated by wrapping sponges with plastic mesh of varying

    In the 1990s, an interdisciplinary group including pediatricians, anthropologists, health educators, psychologists, and statisticians developed and evaluated an HIV prevention intervention targeting early adolescents living in public housing developments in the USA. The intervention, “Focus on Kids,” (FOK) was effective in reducing risk behaviors, intentions, and perceptions and ultimately was included in the Center for Disease Control’s portfolio of effective adolescent programs, “Programs that Work.” Learning about FOK and concerned about the need for a structured program to address high rates of teen pregnancy and risk for HIV, professionals from the Ministries of Health of The Bahamas approached the researchers about collaborating to develop a program for Bahamian youth. A partnership developed which has spanned over a decade and led to the development of an intervention program targeting Bahamian children in grade six, a 10-session adolescent HIV prevention program entitled “Focus on Youth in the Caribbean” (FOYC). Two programs including a video and parent discussion were developed for their parents. Caribbean Informed Parents and Children Together (CImPACT) emphasizes the importance of parent-child communication about sexuality and Goal for It” (GFI) emphasizes the importance of planning ahead. The US-Bahamian team evaluated these interventions through a randomized, controlled 3-celled longitudinal trial (36 months follow-up) involving 15 elementary schools in The Bahamas. The programs have been shown to be effective. This article describes the context in which the epidemic occurred, events leading up to the collaboration and the issues, decisions, processes, and relationships that we have developed that have allowed it to succeed.

    Background Past research suggests that perceived neighbourhood conditions may influence adolescents' emotional health. Relatively little research has been conducted examining the association of perceived neighbourhood conditions with depressive symptoms among Caribbean adolescents. This project examines the association of perceived neighbourhood conditions with levels of depressive symptoms among adolescents in Jamaica, the Bahamas, St. Kitts and Nevis, and St. Vincent. Methods Adolescents attending grade ten of the academic year 2006/2007 in Jamaica, the Bahamas, St. Vincent, and St. Kitts and Nevis were administered the Neighbourhood Characteristics Questionnaire along with the BDI-II. Social cohesion, attachment to the neighbourhood, neighbourhood quality, neighbourhood crime, and neighbourhood disorder scales were created by summing the relevant subscales of the Neighbourhood Characteristics Questionnaire. Multiple regression analyses were used to examine the relationships of perceived neighbourhood conditions to depressive symptoms. Results A wide cross-section of tenth grade students in each nation was sampled (n = 1955; 278 from Jamaica, 217 from the Bahamas, 737 St. Kitts and Nevis, 716 from St. Vincent; 52.1% females, 45.6% males and 2.3% no gender reported; 12 to 19 years, mean = 15.3 yrs, sd = .95 yr). Nearly half (52.1%) of all adolescents reported mild to severe symptoms of depression with 29.1% reporting moderate to severe symptoms of depression. Overall, Jamaican adolescents perceived their neighbourhoods in a more positive manner than those in the Bahamas, St. Vincent and St. Kitts and Nevis. Results of a series of hierarchical multiple regression analyses suggested that a different pattern of neighbourhood factors for each island were associated with depressive symptoms. However, neighbourhood factors were more highly associated with depressive symptoms for Jamaican students than for students in the other three islands. Conclusions

    Recent exploratory activity on Saba Bank in the northeastern Caribbean has provided geologic information showing that this frontier area possesses all of the attributes necessary for the commercial accumulation of hydrocarbons. The first well drilled in the area penetrated 9370 ft (2856 m) of sediments including 3021 ft (921 m) of Eocene carbonates containing zones of good to excellent porosity. Geochemical studies show the presence of good but immature source rocks with the extractable hydrocarbons being migrated rather than indigenous. The geothermal gradient and vitrinite reflectance data indicated the threshold of the oil window would be reached around 10,000 ft (3048 m). The second well was drilled to test a postulated reef on a basement high at a sufficient depth to fall within the oil window. The well bottomed in Eocene andesite at 13,881 ft (4231 m). Reef carbonate was not encountered; the well penetrated turbidite sandstones and siltstones with low to moderate porosity and permeability. A test of gas shows recovered small amounts of C1-C5, but the formation is believed to have been badly damaged by severe mud loss during drilling. Geochemical studies confirm the presence of good source rocks. Reworked unmetamorphosed organic matter of probable early Eocene to Cretaceous age suggests that the Cretaceous cannot be considered economic basement in this area. Reinterpretation of the seismic data explains why the two wells were dry and indicates the presence of a submarine fan area, reefs within the oil window, and large structures in an area of thick sediments of probable Cretaceous age.

    Phytoplankton drives primary productivity in marine pelagic systems. This is also true for the oligotrophic waters in coral reefs, where natural and anthropogenic sources of nutrients can alter pelagic trophic webs. In this study, microphytoplankton assemblages were characterized for the first time in relation to expected coral spawning dates in the Caribbean. A hierarchical experimental design was used to examine these assemblages in Los Roques archipelago, Venezuela, at various temporal and spatial scales for spawning events in both 2007 and 2008. At four reefs, superficial water samples were taken daily for 9 days after the full moon of August, including days before, during and after the expected days of coral spawning. Microphytoplankton assemblages comprised 100 microalgae taxa at up to 50 cells per mL (mean ± 8 SD) and showed temporal and spatial variations related to the coral spawning only in 2007. However, chlorophyll a concentrations increased during and after the spawning events in both years, and this was better matched with analyses of higher taxonomical groups (diatoms, cyanophytes and dinoflagellates), that also varied in relation to spawning times in 2007 and 2008, but asynchronously among reefs. Heterotrophic and mixotrophic dinoflagellates increased in abundance, correlating with a decrease of the diatom Cerataulina pelagica and an increase of the diatom Rhizosolenia imbricata. These variations occurred during and after the coral spawning event for some reefs in 2007. For the first time, a fresh-water cyanobacteria species of Anabaena was ephemerally found (only 3 days) in the archipelago, at reefs closest to human settlements. Variability among reefs in relation to spawning times indicated that reef-specific processes such as water residence time, re-mineralization rates, and benthic-pelagic coupling can be relevant to the observed patterns. These results suggest an important role of microheterotrophic grazers in re-mineralization of organic

    We present a database of published and new relative sea-level (RSL) data for the past 13 ka, which constrains the Holocene sea-level histories of the Caribbean coast of Central and South America (Florida Keys, USA to Guyana) and the Bahamas and Greater and Lesser Antilles islands. Our evaluation of mangrove peat and Acropora palmata sea-level indicators from geological investigations provides 503 sea-level index points and 242 limiting dates. We subdivide the database into 21 regions based on the availability of data, tectonic setting, and distance from the former Laurentide ice sheet. Most index points (75%) and limiting dates (90%) are <8 ka, although there is an unusual temporal distribution with the greatest amount of the data (~28%) occurring between 6-8 ka. We reassess and screen radiocarbon and U/Th ages of mangrove peat and coral data. We use the stratigraphic position (overburden thickness) of index points account for sediment compaction, and use the paleotidal model of Hill et al. (2011) to account for Holocene changes in paleotidal range. A noisy-input Gaussian process regression model calculates that the rates of RSL change were highest during the early Holocene (3-8 mm/yr) and have decreased over time (< 2 mm/yr), which is related to the reduction of ice equivalent meltwater input and collapse of the proglacial forebulge during the Holocene. The sea-level reconstructions demonstrate that RSL did not exceed the present height (0 m) during the Holocene in the majority of locations, with the exception of a small highstand (<2 m) on the northern coast of South America along the Orinoco Delta and Suriname/Guyana located furthest away from the former Laurentide Ice Sheet. The different sea-level histories are an ongoing isostatic response to deglaciation of the Laurentide Ice Sheet and suggest subsidence resulting from collapse of the proglacial forebulge reaches further south than previously considered.

  6. Radium isotopes in the Orinoco estuary and Eastern Caribbean Sea

    1993-02-15

    Radium isotopes provide a means of identifying the source of freshened waters in the ocean and determining the time elapsed since these waters were in the estuary. The authors present evidence that during April, waters from the Amazon mixing zone pass within 50 km of the mouth of the Orinoco River. These Amazon waters are characterized by a lower [sup 228]Ra/[sup 226]Ra activity ratio (AR) than are waters from the Orinoco at similar salinities. During autumn, the increased discharge of the Orinoco displaces the freshened Amazon waters seaward, yet the two can be distinguished clearly. Within the Caribbean Sea, waters of Orinoco origin carry a characteristic radium signature including excess activities of [sup 224]Ra. This isotope may be used to estimate the time elapsed since the waters were removed from contact with sediments. Current speeds based on [sup 224]Ra dating ranged from 15 to 33 cm/s during April. The radium isotopes also provide an assessment of sediment mixing in the estuary. During low discharge (April), considerable mixing of older sediment by physical or biological processes or dredging maintained high activities of [sup 228]Ra in the estuary and produced the highest [sup 228]Ra/[sup 226]Ra AR's yet measured in any estuary. During high discharge (September), a large fraction of the [sup 228]Ra was derived from desorption from fresh sediment rather than mixing of older sediments. Activities of [sup 224]Ra were high in the estuary during both high and low discharge, indicating that considerable mixing of recently introduced sediment must occur during each period. During April, [sup 224]Ra and [sup 228]Ra activities in the water were about equal, indicating that most of the sediment being resuspended had been stored in the estuary long enough to reestablish radioactive equilibrium in the [sup 232]Th decay series (i.e., 20 years). 19 refs., 11 figs., 3 tabs.

These results suggest an important role of microheterotrophic grazers in re-mineralization of organic

  8. A comparative study of atmospheric corrosion in the Caribbean area

    Atmospheric corrosion is a phenomenon of such a magnitude that has been cause of study in several countries for decades. Nevertheless, in Mexico, it became of recent interest due to new economic factors that have involved the Peninsula of Yucatan too. The Yucatan Peninsula is limited to the North and West by the Gulf of Mexico and to the East by the Caribbean Sea. This is a non industrialized region so that in the past very little importance was given to the atmospheric corrosion damage or to the quantification of the high corrosion rates, empirically observed. However, in recent times increased tourism, industrial growth and petroleum extraction have exhibited the need for a better understanding of the atmospheric corrosion processes, as well as a realistic correlation to parameters such as time-of-wetness, levels of pollution by airborne salinity, atmospheric S0{sub 2} and corrosivity categories for the metals. To evaluate these parameters, five tests sites were selected following ISO recommendations. Three sites are marines atmospheres, one urban and one rural. Corrosion rates for commercial laminated Cu and carbon steel, as well as deposition rates of pollutants, were determined after one year exposure in the test sites. Applying the standard practice ISO 9223 a categorization of the corrosivity and of the level of pollutants was carried out. The marine environments were classified as of atmospheric corrosivity C{sub 5}, while the urban and the rural could be classified as C{sub 3}, respectively. The pollution values showed that the exposure sites were essentially contaminated with chloride with classification S{sub 1} for the rural site and S{sub 3} for the marine atmosphere.

    This study compares the health conditions of domestic Caribbeans with those living in the United States to explore how national context and migration experiences might influence substance use (i.e., alcohol or drug) and other mental and physical health conditions. The study is based upon probability samples of non-institutionalized Caribbeans living in the United States (1621), Jamaica (1216) and Guyana (2068) 18 years of age and over. Employing descriptive statistics and multivariate analytic procedures, the results revealed that substance use and other physical health conditions and major depressive disorder and mania vary by national context, with higher rates among Caribbeans living in the United States. Context and generation status influenced health outcomes. Among first generation black Caribbeans, residing in the United States for a longer length of time is linked to poorer health outcomes. There were different socio-demographic correlates of health among at-home and abroad Caribbeans. The results of this study support the need for additional research to explain how national context, migratory experiences and generation status contribute to understanding substance use and mental disorders and physical health outcomes among Caribbean first generation and descendants within the United States, compared to those remaining in the Caribbean region.

    2010-12-01

    The member states of the Caribbean Community (CARICOM) have the highest prevalence of chronic noncommunicable diseases (CNCDs) in the Americas. The CARICOM heads of government issued the Port-of-Spain Declaration "Uniting to Stop the Epidemic of Chronic Non-Communicable Diseases in the Caribbean," mandating intersectoral, population-based approaches and commemoration of the summit on the second Saturday in September as "Caribbean Wellness Day (CWD)." CWD, inaugurated in September 2008, is designed to strengthen public, private, and civil society partnerships and to promote multicountry, multisectoral activities in support of wellness. By 2009, the second year of the celebrations, 18 of the 20 CARICOM countries embraced and celebrated with multifaceted, multifocal activities, using this as a catalyst for sustained physical activities, healthy food choices, and health screening in a smoke-free environment. Organizational support and Caribbean branding of products came from the Pan American Health Organization/World Health Organization and CARICOM. Outcomes will be measured by input and process indicators and CNCD risk factor surveillance. PMID:21308174

    This study investigates the sensitivity of the one-way nested PRECIS regional climate model (RCM) to domain size for the Caribbean region. Simulated regional rainfall patterns from experiments using three domains with horizontal resolution of 50 km are compared with ERA reanalysis and observed datasets to determine if there is an optimal RCM configuration with respect to domain size and the ability to reproduce important observed climate features in the Caribbean. Results are presented for the early wet season (May-July) and late wet season (August-October). There is a relative insensitivity to domain size for simulating some important features of the regional circulation and key rainfall characteristics e.g. the Caribbean low level jet and the mid summer drought (MSD). The downscaled precipitation has a systematically negative precipitation bias, even when the domain was extended to the African coast to better represent circulation associated with easterly waves and tropical cyclones. The implications for optimizing modelling efforts within resource-limited regions like the Caribbean are discussed especially in the context of the region's participation in global initiatives such as CORDEX.

    2015-04-01

    A database of landslides that caused loss of life in Latin America and the Caribbean in the period from 2004 and 2013 inclusive has been compiled using established techniques. This database indicates that in the ten year period a total of 11 631 people lost their lives across the region in 611 landslides. The geographical distribution of the landslides is very heterogeneous, with areas of high incidence in parts of the Caribbean (most notably Haiti), Central America, Colombia, and SE. Brazil. The number of landslides varies considerably between years; the El Niño/La Niña cycle emerges as a major factor controlling this variation, although the study period did not capture a large event. Analysis suggests that on a continental scale the mapped factors that best explain the observed distribution are topography, annual precipitation and population density. On a national basis we have compared the occurrence of fatality-inducing landslide occurrence with the production of research articles with a local author, which shows that there is a landslide research deficit in Latin America and the Caribbean. Understanding better the mechanisms, distributions causes and triggers of landslides in Latin America and the Caribbean must be an essential first step towards managing the hazard.

    Latin America and the Caribbean (LAC) is a region with similarities and important disparities. In recent years LAC has witnessed achievements, with HIV prevalence rates relatively stable for LA and decreasing for the Caribbean. However average values hide differences. General population HIV prevalence in LAC is 0.4 % on average. In the Caribbean there are fewer new HIV infections but HIV prevalence among adults exceeds 1 % in several countries. It is estimated that 31 % of adults living with HIV in LA and 52 % of adults in the Caribbean are women. Unprotected sex is the main route of HIV transmission in LAC. Men who have sex with men and transgender women are the populations with the highest prevalence (10.6 % and 17.7 % respectively); however other key populations such as female sex workers (4.9 %), drug users (range 1 %-49.7 % for intravenous drug users), prisoners and indigenous populations are also important. LAC has the highest anti-retroviral treatment coverage of any low- and middle-income region in the world, but women and children are less likely than men to receive treatment. There is an important pending agenda to address the gaps in information, prevention, and care for HIV in LAC. PMID:24824881

  19. Can a thermally tolerant symbiont improve the future of Caribbean coral reefs?

    PubMed

    Ortiz, Juan Carlos; González-Rivero, Manuel; Mumby, Peter J

    2013-01-01

    The detrimental effect of climate change induced bleaching on Caribbean coral reefs has been widely documented in recent decades. Several studies have suggested that increases in the abundance of thermally tolerant endosymbionts may ameliorate the effect of climate change on reefs. Symbionts that confer tolerance to temperature also reduce the growth rate of their coral host. Here, we show, using a spatial ecosystem model, that an increment in the abundance of a thermally tolerant endosymbiont (D1a) is unlikely to ensure the persistence of Caribbean reefs, or to reduce their rate of decline, due to the concomitant reduction in growth rate under current thermal stress predictive scenarios. Furthermore, our results suggest that given the documented vital rates of D1a-dominated corals, increasing dominance of D1a in coral hosts may have a detrimental effect by reducing the resilience of Caribbean reefs, and preventing their long-term recovery. This is because Caribbean ecosystems appear to be highly sensitive to changes in the somatic growth rate of corals. Alternative outcomes might be expected in systems with different community-level dynamics such as reefs in the Indo-Pacific, where the ecological costs of reduced growth rate might be far smaller.

  20. 2005 Caribbean mass coral bleaching event: A sea surface temperature empirical orthogonal teleconnection analysis

    Simonti, Alicia L.; Eastman, J. Ronald

    2010-11-01

    This study examined the effects of climate teleconnections on the massive Caribbean coral bleaching and mortality event of 2005. A relatively new analytical procedure known as empirical orthogonal teleconnection (EOT) analysis, based on a 26 year monthly time series of observed sea surface temperature (SST), was employed. Multiple regression analysis was then utilized to determine the relative teleconnection contributions to SST variability in the southern Caribbean. The results indicate that three independent climate teleconnections had significant impact on southern Caribbean anomalies in SST and that their interaction was a major contributor to the anomalously high temperatures in 2005. The primary and approximately equal contributors were EOT-5 and EOT-2, which correlate most strongly with the tropical North Atlantic (TNA) and Atlantic multidecadal oscillation (AMO) climate indices, respectively. The third, EOT-9, was most strongly related to the Atlantic meridional mode. However, although statistically significant, the magnitude of its contribution to southern Caribbean variability was small. While there is debate over the degree to which the recent AMO pattern represents natural variability or global ocean warming, the results presented here indicate that natural variability played a strong role in the 2005 coral bleaching conditions. They also argue for a redefinition of the geography of TNA variability.

  2. What drives microplate motion and deformation in the northeastern Caribbean plate boundary region?

    NASA Astrophysics Data System (ADS)

    Benthem, Steven; Govers, Rob; Wortel, Rinus

    2014-05-01

    The north Caribbean plate boundary zone is a broad deformation zone with several fault systems and tectonic blocks that move with different velocities. The indentation by the Bahamas Platform (the "Bahamas Collision") is generally invoked as a cause of this fragmentation. We propose that a second driver of deformation is the western edge of the south dipping Puerto Rico slab moving sideways with the North America plate. The westward motion of the slab edge results in a push on the Caribbean plate farther west. We refer to this second mechanism for deformation as "Slab Edge Push." The motion of the North America plate relative to the Caribbean plate causes both drivers to migrate from east to west. The Bahamas Collision and Slab Edge Push have been operating simultaneously since the Miocene. The question is the relative importance of the two mechanisms. We use mechanical finite element models that represent the two mechanisms from the late Oligocene (30 Ma) to the present. For the present, both models successfully reproduce observed deformation, implying that both models are viable. Back in time the Slab Edge Push mechanism better reproduces observations. Neither mechanism successfully reproduces the observed Miocene counterclockwise rotation of Puerto Rico. We use this rotation to tune a final model that includes fractional contributions of both mechanisms. We find that the Slab Edge Push was the dominant driver of deformation in the north Caribbean plate boundary zone since 30 Ma.

  3. Religious involvement and suicidal behavior among African Americans and Black Caribbeans.

    Taylor, Robert Joseph; Chatters, Linda M; Joe, Sean

    2011-07-01

    This study explores the relationship between religious denomination, four dimensions of religious involvement, and suicidality (lifetime prevalence of suicide ideation and attempts) within a nationally representative sample of African American and Black Caribbean adults. The relationship between religious involvement and suicide for African Americans and Black Caribbeans indicated both similarities and differences. For both groups, religious involvement was largely protective against suicidal ideation and attempts, although, in some instances, specific measures were associated with higher suicidality. Looking to God for strength, comfort, and guidance was protective against suicidal attempts and ideation, whereas stating that prayer is important in stressful situations was associated with higher levels of ideation for both groups and higher attempts among Black Caribbeans. For African Americans, reading religious materials was positively associated with suicidal ideation. Among Black Caribbeans, subjective religiosity was negatively associated with ideation, and being Catholic was inversely associated with attempts, whereas being Pentecostal was inversely associated with ideation. These findings are discussed in relation to previous research and current conceptual frameworks that specify multiple (e.g., prevention and resource mobilization) and often divergent pathways of religious effects on physical and mental health outcomes.

    For the first time in the southern Caribbean Sea Margin of Colombia (between 450 - 700 m deep) we confirm the presence of methane seep communities near the deltas of the Magdalena and Sinu rivers. Some evidences of the occurrence of those communities include: i) bivalves constituents of marine chemosynthesis-based communities, which are indicators of reducing environments as vesicomyid and lucinid bivalves (Vesicomya caribbea, Calyptogena ponderosa, Ectenagena modioliforma, Lucinoma spp. and Graecina colombiensis), together with the rare solemyid clam Acharax caribbaea, ii) other seep-associated fauna such as the trochid snail Cataegis meroglypta, iii) the first report of vestimentiferan tubeworms for the area and, iv) the presence of authigenic carbonates; these constructions form hard substrates colonized by sessile fauna. Additionally, more than 20 species of benthic non-seep fauna were found associated in the area. The collected fauna exhibits an elevated taxonomic similarity to other modern and fossil seep communities from the Caribbean (Barbados Prism, Gulf of Mexico, Cenozoic seep taxa from Barbados, Trinidad and Venezuela). The presence of these chemosymbiotic species seems to be related to mud diapirism activity in the South West of the Colombian coast, this geologic characteristic indicates tectonic and depositional processes associated with the aforementioned deltas. Further research is necessary to establish biological and geological interactions, geochemical and geophysical controls, and organization of cold seeps communities in this unexplored area of the Caribbean.

    A recent research cruise to examine small, detached carbonate platforms situated on the Nicaraguan Rise in the SW Caribbean Sea has revealed the presence of numerous Halimeda bioherms. Based upon interpretations from seismic reflection data some exceed 140 m in relief. This is the first documented occurrence of these green-algal buildups in the Caribbean/Bahama Bank region. The Halimeda bioherms form a nearly continuous band that borders the margins of the Miskito Channel—a shallow, open, 125 km long seaway. This 220 m deep channel bisects the Miskito Bank which is a major carbonate shelf. In seismic profile the bioherms appear acoustically “soft” and reveal a local relief of 20 30 m. Tops of these features lie in about 40 50 m of water. Samples from dredge hauls are coarse, poorly cemented packstones/grainstones which are dominated by largely unbroken, disarticulated Halimeda segments set in a poorly sorted sandy matrix. Exposed surfaces were stained brown. Very little living material was brought up in the dredges. The significance of these bioherms and their full extent in the Caribbean are not understood. Undoubtedly, further study will provide important answers concerning their role in the geologic development of Caribbean carbonate platforms.

  15. A limited assessment and characterization of the solar radiation energy resources in the Caribbean region

    1988-02-01

    The objective of our work was to produce a preliminary assessment and characterization of the Caribbean region (Barbados, Dominican Republic, Guatemala, Jamaica, and Panama) solar radiation energy resources. Such information will be used to estimate the performance of, and identify the most promising applications of, solar heat technologies in the Caribbean region. We expect the solar radiation resources in the Caribbean region to be very location specific. Sunny areas will have an annual direct-beam resource of about 3,000 kWhm/sup /minus 2// and a global solar radiation resource of about 2,500 kWhm/sup /minus 2//. Cloud-covered areas will have annual solar radiation resources of about 1,500 kWhm/sup /minus 2/ for both the direct-beam and the global solar radiation. Monthly levels of solar radiaion will vary markedly, ranging from an average of 9 to 3 kWhm/sup /minus 2//day/sup /minus 1// for the direct-beam and from an average of 7 to 4 kWhm/sup /minus 2//day/sup /minus 1// for the global solar radiation. The Caribbean region is comparable to the Great Plains region of the US, in terms of annual solar radiation resources; however, thorough ''prospecting'' is required to avoid areas having very low amounts of solar radiation.

  5. The Changing Face of HIV in Latin America and the Caribbean

    García, Patricia J; Bayer, Angela; Cárcamo, César P

    2014-01-01

    Latin America and the Caribbean (LAC) is a region with similarities and important disparities. In recent years LAC has witnessed achievements, with HIV prevalence rates relatively stable for LA and decreasing for the Caribbean. However average values hide differences. General population HIV prevalence in LAC is 0.4% in average. In the Caribbean there are fewer new HIV infections but HIV prevalence among adults exceeds 1% in several countries. It is estimated that 31% of adults living with HIV in LA and 52% of adults in the Caribbean are women. Unprotected sex is the main route of HIV transmission in LAC. Men who have sex with men and transgender women are the populations with the highest prevalence (10.6% and 17.7% respectively); however other key populations such as female sex workers (4.9%), drug users (range 1%-49.7% for intravenous drug users). Prisoners and indigenous populations are also important. LAC has the highest anti-retroviral treatment coverage of any low- and middle-income region in the world, but women and children are less likely than men to receive treatment. There is an important pending agenda to address the gaps in information, prevention and care for HIV in LAC. PMID:24824881

  7. Flattening of Caribbean coral reefs: region-wide declines in architectural complexity.

    Coral reefs are rich in biodiversity, in large part because their highly complex architecture provides shelter and resources for a wide range of organisms. Recent rapid declines in hard coral cover have occurred across the Caribbean region, but the concomitant consequences for reef architecture have not been quantified on a large scale to date. We provide, to our knowledge, the first region-wide analysis of changes in reef architectural complexity, using nearly 500 surveys across 200 reefs, between 1969 and 2008. The architectural complexity of Caribbean reefs has declined nonlinearly with the near disappearance of the most complex reefs over the last 40 years. The flattening of Caribbean reefs was apparent by the early 1980s, followed by a period of stasis between 1985 and 1998 and then a resumption of the decline in complexity to the present. Rates of loss are similar on shallow (<6 m), mid-water (6-20 m) and deep (>20 m) reefs and are consistent across all five subregions. The temporal pattern of declining architecture coincides with key events in recent Caribbean ecological history: the loss of structurally complex Acropora corals, the mass mortality of the grazing urchin Diadema antillarum and the 1998 El Nino Southern Oscillation-induced worldwide coral bleaching event. The consistently low estimates of current architectural complexity suggest regional-scale degradation and homogenization of reef structure. The widespread loss of architectural complexity is likely to have serious consequences for reef biodiversity, ecosystem functioning and associated environmental services. PMID:19515663

  14. 8.2 ky event associated with high precipitation in the eastern Caribbean

    NASA Astrophysics Data System (ADS)

    Winter, A.; Vieten, R.; Miller, T.; Mangini, A.; Scholz, D.

    2013-12-01

    We present data from speleothems collected in Venezuela and Puerto Rico showing that the eastern Caribbean was anomalously moist during the 8.2ka event. Evidence from high-resolution analyses of Greenland ice core (GISP2) shows that at the same time northern Europe and the north Atlantic were cooler by 3 - 6° C. The trigger for the 8.2ka event is thought to be pulsed meltwater discharges from a multi-event drainage of proglacial lakes associated with the decaying Laurentide Ice Sheet margin. The meltwater apparently slowed the thermohaline circulation decreasing warmth to northern Europe. At the same time moisture transfer to the northern latitudes may have slowed resulting in the observed lower latitude precipitation patterns. The eastern Caribbean seems to be especially sensitive to the changes in the strength of the Atlantic meridional overturning circulation (AMOC). Higher precipitation values may also have increased lowland flooding along the coastal areas of north eastern South America, already affected by early Holocene sea-level change, and are linked to social territory reshuffling which stimulated the earliest migrations into the Caribbean Archipelago shortly afterwards. Our age models based on precise MC-ICPMS 230Th/U-dating indicate that the eastern Caribbean stalagmites all grew at about the same rate of 15 cm through the 8.2 ka event, much faster than during any other growth period, except today when they are also growing at an accelerated rate.
