Detection of a meteoritic component in Ivory Coast tektites with rhenium-osmium isotopes  

Microsoft Academic Search

Measurement of rhenium (Re) and osmium (Os) concentrations and Os isotopic compositions in Ivory Coast tektites (natural glasses with upper crustal compositions that are ejected great distances during meteorite impact) and rocks from the inferred source crater, Lake Bosumtwi, Ghana, show that these tektites incorporate about 0.6 percent of a meteoritic component.

Osmium isotopes in Ivory Coast tektites: Confirmation of a meteoritic component and rhenium depletion  

NASA Technical Reports Server (NTRS)

The sensitive negative thermal ionization mass spectrometry method was used for the measurement of concentrations and isotopic ratios of osmium and rhenium in four Ivory Coast tektites. These tektites have crustal major and trace element composition, as well as large negative epsilon(sub Nd)(-20) and positive epsilon(sub Sr)(+260 to +300) which are characteristic for old continental crust. Os concentrations ranging from 0.09 to 0.30 ppb were found, clearly much higher than average crustal values, Os-187/Os-186 ratios of about 1.2-1.7, and low Re-187/Os-186 ratios. These results show unambiguously the existence of a meteoritic component (on the order of 0.06%) in the Ivory Coast tektites. Low Re abundances are the result of fractionation of Re during the impact.

Single crystal U-Pb zircon age and Sr-Nd isotopic composition of impactites from the Bosumtwi impact structure, Ghana: Comparison with country rocks and Ivory Coast tektites.  

PubMed

The 1.07 Myr old Bosumtwi impact structure (Ghana), excavated in 2.1-2.2 Gyr old supracrustal rocks of the Birimian Supergroup, was drilled in 2004. Here, we present single crystal U-Pb zircon ages from a suevite and two meta-graywacke samples recovered from the central uplift (drill core LB-08A), which yield an upper Concordia intercept age of ca. 2145 ± 82 Ma, in very good agreement with previous geochronological data for the West African Craton rocks in Ghana. Whole rock Rb-Sr and Sm-Nd isotope data of six suevites (five from inside the crater and one from outside the northern crater rim), three meta-graywacke, and two phyllite samples from core LB-08A are also presented, providing further insights into the timing of the metamorphism and a possibly related isotopic redistribution of the Bosumtwi crater rocks. Our Rb-Sr and Sm-Nd data show also that the suevites are mixtures of meta-greywacke and phyllite (and possibly a very low amount of granite). A comparison of our new isotopic data with literature data for the Ivory Coast tektites allows to better constrain the parent material of the Ivory Coast tektites (i.e., distal impactites), which is thought to consist of a mixture of metasedimentary rocks (and possibly granite), but with a higher proportion of phyllite (and shale) than the suevites (i.e., proximal impactites). When plotted in a Rb/Sr isochron diagram, the sample data points (n = 29, including literature data) scatter along a regression line, whose slope corresponds to an age of 1846 ± 160 Ma, with an initial Sr isotope ratio of 0.703 ± 0.002. However, due to the extensive alteration of some of the investigated samples and the lithological diversity of the source material, this age, which is in close agreement with a possible "metamorphic age" of ? 1.8-1.9 Ga tentatively derived from our U-Pb dating of zircons, is difficult to consider as a reliable metamorphic age. It may perhaps reflect a common ancient source whose Rb-Sr isotope systematics has not basically been reset on the whole rock scale during the Bosumtwi impact event, or even reflect another unknown geologic event.

Violence in the Ivory Coast  

NSDL National Science Digital Library

After Sunday's presidential election in the Ivory Coast (or Cote d'Ivoire), violence broke out when two candidates, the Ivory Coast's military ruler, General Robert Guei, and Laurent Gbagbo, Guei's main opponent, both declared that they had won the election. Thousands of Gbagbo supporters protested in the streets of the country's capitol, Abidjan and were met by military authorities, who responded with live ammunition, teargas, and batons. In the following three days, at least 60 people were killed. The conflict has also threatened relations between the Ivory Coast's ethnic groups. Guei's supporters mainly live in the country's northern, Muslim region, while Gbagdo represents the Christians living in the western and southern regions. Both mosques and churches have been looted and set on fire. On Thursday the official vote was released by the national electoral commission: Gbagbo received 59 percent of the vote, and Guei, 32 percent. Later that day, Gbagdo was swore in as president, as Guei went into hiding. The violence in Abidjan seems to have settled. Today, Gbagdo named Affi N'Guessan as the Ivory Coast's new prime minister. Previously, N.Guessan was the Minister of Industry and Tourism in Guei's government. The new president has also vowed to keep Guei's timetable to return the Ivory Coast to democracy.

Nd and SR isotopic evidence for the origin of tektite material from DSDP site 612 off the New Jersey coast  

NASA Astrophysics Data System (ADS)

The Sr and Nd isotopic composition was analyzed for samples from the Late Eocene tektite material from DSDP site 612 off the New Jersey coast, to determine whether these tektites may be assigned to the North-American-tektite group. It was found that the ranges of the Sr-87/Sr-86 and the Nd-143/Nd-144 ratios were much wider than in the 612-tectite material than in the tightly constrained group of North American tektites and microtektites and were significantly different from ratios in other groups of tektites. Results indicate that the DSDP tektites were formed from a chemically and isotopically heterogeneous material, in a regime that was different from that of other groups of tektites. It is suggested that the 612-tectites and the North American tektites were either formed by impacts of several bolides in the same general area or by a single impact event that sampled different layers.

Nd and Sr isotopic compositions of tektite material from Barbados and their relationship to North American tektites  

NASA Technical Reports Server (NTRS)

The isotopic composition of microtektites from Barbados was determined to establish their possible source and their relationship to known tektite strewn fields. Analyzed samples included microtektites and tektite fragments from the Barbados oceanic beds, samples of deep sea ooze, in which they occur, and of underlying volcanic ash, as well as glass beads from Lake Wanapitei Crater. Isotope ratios (Sr-87/Sr-86, Nd-143/Nd-144, Rb-87/Sr-86, and Sm-147/Nd-144) were determined, and the epsilon values for Sr and Nd plotted on the diagram available for the fields of North America, Australia, Ivory Coast, and Moldavite tektites. The epsilon coordinates of all Barbados microtektite and bulk tektite samples plot precisely within the narrow field determined by North American tektites (epsilon Sr, 111; epsilon Nd, -6.2), yield an Nd model age of 0.6 AE, and are distinct from all other fields. The isotopic signatures of samples from sea ooze, ash layer, and of the Lake Wanapitei glass beads are clearly different from all known tektite classes. It is concluded that the Barbados tektites are of the same source and temporal event as the North American tektites.

Fragmentation and hydration of tektites and microtektites  

USGS Publications Warehouse

An examination of data collected over the last 30 years indicates that the percent of glass fragments vs. whole splash forms in the Cenozoic microtektite strewn fields increases towards the source crater (or source region). We propose that this is due to thermal stress produced when tektites and larger microtektites fall into water near the source crater while still relatively hot (>1150 ??C). We also find evidence (low major oxide totals, frothing when melted) for hydration of most of the North American tektite fragments and microtektites found in marine sediments. High-temperature mass spectrometry indicates that these tektite fragments and microtektites contain up to 3.8 wt% H2O. The H2O-release behavior during the high-temperature mass-spectrometric analysis, plus high Cl abundances (???0.05 wt%), indicate that the North. American tektite fragments and microtektites were hydrated in the marine environment (i.e., the H2O was not trapped solely on quenching from a melt). The younger Ivory Coast and Australasian microtektites do not exhibit much evidence of hydration (at least not in excess of 0.5 wt% H2O); this suggests that the degree of hydration increases with age. In addition, we find that some glass spherules (with 65 wt% SiO2 can undergo simple hydration in the marine environment, while impact glasses (with <65 wt% SiO2) can also undergo palagonitization.

[Traditional health practitioners and epilepsies in Ivory Coast].  

PubMed

We report the results of a descriptive 3-month observational study concerning the experience and knowledge about epilepsy of 30 traditional health practitioners in the Ivory Coast. Most respondents were men over 30 years of age. They had an average of 14.3 years of professional experience. More than half of respondents (54%) had not attended school. All traditional practitioners knew that epilepsy was a brain disease. For 83.3% of them, the disease was supernatural, due to a curse. These traditional healers knew all the clinical manifestations of generalized tonico-clonic seizure. For over 72% of them, noise, presence of a public, nervousness and coffee consumption were factors favoring seizures. Sixty percent of the traditional healers still believed in the contagiousness of epilepsy, and all claimed to cure it by traditional treatment. Most all healers (97%) used plant products, but only 10% released the name of the plants used (Rubiaceae or Lamiaceae families). This survey highlights the urgency of awareness campaigns and the need for training of Ivorian traditional healers and the necessity to improve the collaboration between modern and traditional medicine.

Energy assessment of Ivory Coast, Morocco, Nigeria, and Senegal  

SciTech Connect

This report is an overview of the energy market in four West African countries: The Ivory Coast, Morocco, Nigeria, and Senegal. We feel these countries are representative of the West African region. Together they account for 75% of the total energy use in West Africa, 78% of GDP, and 76% of population. The purpose of the study is to analyze the evolution of energy demand in the context of the general socio-economic background of the region. The study also examines energy supply and trade related to the energy sector. The analysis focuses on the study of commercial fuels. Although we have reviewed studies of wood, solar, wind, and agricultural residues, we leave out detailed discussions of these non-commercial energy forms. The first part of the report is an assessment of the trends in energy demand in the four study countries. We discuss the main factors driving energy demand sector by sector. This is followed by a review of the primary energy resources of the countries, and of the capacity for production of secondary fuels. The last section looks at energy trade, with particular emphasis on the role of the United States.

Essential oil of three Uvaria species from Ivory Coast.  

PubMed

Different parts of Uvaria ovata (Dunals) A, U. anonoides Baker f. and U. tortilis A. Chev were collected from Ivory Coast, in Toumodi (center), Agboville (south-east) and Sikensi (south), respectively. The essential oils, obtained by hydrodistillation using a Clevenger-type apparatus, were investigated by CG and CG/MS. The proportion of the chromatographed constituents identified varied from 92.5% to 98.5%. For U. ovata, the root bark oil comprised mainly camphene (10.2%), beta-pinene (10.1%), epi-alpha-cadinol (13.2%) and intermedeol (9.7%), while the oil of the stem bark was dominated by epi-alpha-cadinol (27.3%), intermedeol (11.9%) and benzyl benzoate (13.4%). The oil of the leaves showed beta-caryophyllene (15.6%), germacrene D (24.2%) and benzyl benzoate (18.3%) as the most abundant constituents. The leaf oil of U. anonoides was rich in 2,5-dimethoxy-p-cymene (15.5%), bicyclogermacrene (21.3%) and benzyl benzoate (8.7%), while, gamma-terpinene (31.7%), beta-caryophyllene (23.9%) and germacrene D (15.8%) constituted the main components of the stem bark oil of U. tortilis.

Reasons for blood donation deferral in sub-Saharan Africa: experience in Ivory Coast  

PubMed Central

INTRODUCTION Blood donor selection is important to ensure the safety of both donors and recipients. There is a paucity of data on reasons for blood donor deferral in Ivory Coast. The aim of this study was to identify the reasons for predonation deferral at a blood collection site at General Hospital, Yopougon Attié in Abidjan. MATERIALS AND METHODS The investigators conducted a retrospective audit of data pertaining to donor deferral for blood donors that presented to the general hospital of Yopugon Attié from January 1, 2006 to December 31, 2008. RESULTS A total of 10,694 prospective blood donors, presented over the study period, and 24,363 attempts to donate were registered. The majority were repeat blood donors (77.4%). A total of 2618 (10.8%) donors were deferred. The most frequent reason for deferral was a low hemoglobin level (42.5%), with females constituting the majority of those deferred. The second most frequent reason for deferral was a reported change of or new sexual partner (34.3%); male donors were predominant in this group. Additional reasons for deferral included short interdonation interval (4.6%) and reactivity for a screened biomarker (2.3%). CONCLUSION Although the rates for permanent and temporary deferral rates are similar between the Ivory Coast and high-middle income countries, the causes and demographics differ. The reasons for exclusion are preventable through awareness and education of prospective blood donors. PMID:22780941

[AIDS prevention by a youth association in Ivory Coast: impact, successes and disappointments].  

PubMed

Over the last few years, the number of associations involved in AIDS prevention has dramatically increased in Ivory Coast, especially in Abidjan. This article describes an experiment in the prevention of AIDS and STDs among young people in Abidjan by means of peer education. It follows the management and progress of a youth organization for AIDS prevention, CESAM (Cellule Scolaire Anti-SIDA et MST), the School-based Anti-AIDS and STD Unit. Critical review of the activities of this association identifies a number of methodological, planning, human and material problems, which have received little attention in the past. CESAM is one of the first anti-AIDS associations in Ivory Coast to target young people and to have young members. This may be the reason for some of its successes and some of its failures and disappointments. The association's successes include the provision of information to more than 25,000 people between 1992 and 1996, and the overall satisfaction of the public and local AIDS institutions. The young people involved have taken on a new social identity, which has developed from the motivation of association members and the personal experiences of some with respect to AIDS, STDs and problems associated with contraception. However, this new identity is threatened by rivalry between members and the search for funding, as the substantial funding obtained in 1994-1995 can show it. PMID:10623875

Preliminary cost-effectiveness analysis of an AIDS vaccine in Abidjan, Ivory Coast.  

PubMed

A preliminary assessment was made of the cost-effectiveness of a hypothetical AIDS vaccine in Abidjan, Ivory Coast. A total cost of $20,079 per HIV positive case in the Ivory Coast was projected by estimating the indirect and direct costs of infection. The HIV vaccine was then estimated to increase by $5.28; the costs of a fully immunized child (plus costs of the vaccine). After using this data and taking into account that at least 5% of a cohort of vaccine-eligible infants would become HIV positive at approximately age 26, a cost-benefit analysis was undertaken varying cost, efficacy rates for the hypothetical vaccine and HIV seroprevalence rates in order to indicate at what price per individual dose of vaccine would it stop being cost-beneficial. Furthermore, the basic model was expanded to include vaccinating young adults and the added benefits associated with decreased HIV transmission especially in individuals with high risk behavior. The model was expanded to examine the effects of a changing discount rate. Because of the tremendous economic burden due to AIDS, the prospective vaccine costs at which there is no economic benefit were higher than expected. PMID:10128800

Mineralogical, crystallographic and morphological characteristics of natural kaolins from the Ivory Coast (West Africa)  

NASA Astrophysics Data System (ADS)

Thirteen clay samples from four deposits in the Ivory Coast (West Africa) were studied using X-ray diffraction, thermogravimetric analysis and chemical analysis. Mineralogical, crystallographic and morphological characteristics of these samples are given. Kaolinite is the principal mineral but other minerals are present in small quantities: illite, quartz, anatase and iron oxides (oxides and oxyhydroxides). The crystallographic, morphological and surface characteristics are influenced by the presence of these impurities. In particular, the presence of iron oxides was associated with reduced structural ordering and thermal stability of kaolinite and increased specific surface area. These clays could be used in the ceramics industry to make tiles and bricks, and also in agronomy as supports for chemical fertilizers or for environmental protection by immobilising potentially toxic waste products.

Female genital mutilation and intimate partner violence in the Ivory Coast  

PubMed Central

Background Serious forms of violence against women include Female Genital Mutilation (FGM) and Intimate Partner Violence (IPV). The aim of this study was to determine if FGM is associated with IPV, using data obtained from the Demographic and Health Survey (DHS) 2012 in Ivory Coast. Methods Participants for this study were drawn from the 2011-12 Ivory Coast Demographic and Health Survey (CDHS), a nationally representative sample of 10060 women aged 15 to 49 years. The analysis of this paper is restricted to the sample of women who responded to the FGM and domestic violence modules (N?=?5005). Results The lifetime prevalence of physical violence was 24.8%, sexual violence, 5.7%, and emotional violence, 19.0%, and the prevalence of any lifetime IPV was 32.1%. In all, 40.6% reported female genital cutting or mutilation (FGM). Women reporting FGM were two times as likely to experience sexual IPV (AOR: 1.96, CI: 1.29-2.98), while other subtypes of IPV were higher in women reporting FGM but they were not significant. Of the socio-demographic covariates, urban residence and having a primary education were associated with most subtypes of IPV, while being a Muslim seemed protective from any type, sexual and emotional IPV. Having seen the father beating the mother was positively associated with most IPV subtypes, and having been diagnosed with a sexually transmitted infection (STI) in the previous 12 months was associated with physical and sexual IPV. Conclusion Significant rates of FGM and IPV were found among this sample of Ivorian women calling for the need for multiple strategies to reduce FGM and IPV. PMID:24451017

Regulation of business activities of petroleum contractors in Cameroon, Congo, Gabon, and Ivory Coast  

SciTech Connect

Foreign companies engaging in business in Cameroon, Congo, Gabon, and Ivory Coast are subject to a broad range of regulations. This article deals only with those aspects of the regulations that are most important to petroleum contractors intending to engage in business in these countries. The regulator scheme actually applicable in a given case will depend on the legal structure through which a corporation operates. An American corporation may envisage engaging in business on a long-term basis through a local subsidiary or branch. On the other hand, it may wish only to perform temporary activities pursuant to one or more fixed-duration contracts with petroleum companies operating in one of countries. Each of these situations is dealt with. Common features of each area of regulation were described and the differences in regulations were presented. These topics were included: exchange control regulation, corporate forms of business association, authorization to engage in business, requirement of government or local participation in capital, investment code incentives, labor law requirements, taxation of corporations, taxation of profits, taxation of income from movable capital, taxation of amounts paid abroad as technical assistance fees, royalties and similar compensation, turnover taxes, payroll taxes, taxation of business performed without forming a local company or branch, taxation of employees and Social Security contributions.

[Vectorial transmission of malaria in shrubby Savannah area at Ganse, Ivory Coast].  

PubMed

A longitudinal entomologic study was carried out in the village of Ganse located in the Northeastern Ivory Coast from July 2000 to July 2001. The threefold purpose of the study was to index Plasmodium-carrying Anopheles species by capturing mosquitoes on human volunteers, collecting larvae in different dwelling types, and evaluating the involvement each species in the malaria transmission. A total of 4 species belonging to the Anopheles genus were collected in the village. Identification of circumsporozoite protein using the ELISA technique demonstrated that three species were plasmodium vectors. These species belonged to the An. gambiae complex (An. gambiae s.s. 100%), to the An. funestus group (An. funestus s.s. 95.6%) and to the An. nill group (An. nili s.s. 100%). The estimated mean sporozoite index was 5.9% for An. gambiae s.l., 4.3% for the An. funestus group and 2.6% for the An. nili group. The main larva breeding sites were standing water such as puddles for An. gambiae s.l., streams with tall plants for the An. funestus group and the Comoe River for An. nili group. Because peak breeding of these three species occurs at three successive times; i.e., in May, September and July respectively, transmission of P. falciparum is continuous throughout the year. The transmission rate is high since we recorded up to up to 410 infected bites per person per year. In addition to showing the presence of An. rivulorum-like, our findings in the area demonstrates the important role of An. nili s.s. in the transmission and the complexity of the vectorial system.

Tektite 2 habitability research program  

NASA Technical Reports Server (NTRS)

Multi-level parameters relating to perceived life quality in an isolated research and residence quarters were measured using a variety of tests. The habitat under study, emplaced beneath the sea off the coast of St. John's Island as a part of the Tektite II program, was being used for marine research. The crew for each of the 10 missions consisted of one engineer and 4 scientists. One mission had an all-female crew. Mission length was either 14 or 20 days, and 4 engineers, in covering 6 missions, stayed in the habitat for periods of 30 days each. A personality test was taken before confinement in the habitat. Two attitude tests were filled out by the aquanauts while they were still in the habitat. Daily moods were monitored during all missions. Special observations were made of leisure time use. Standardized private debriefings were administered at the end of each mission to each aquanaut. Other behavioral observations made by another research team were intercorrelated with the other measures described above.

Paleoclimatic and deforestation effect on the chemical and isotopic composition of the coastal fresh groundwater resources of South-east Ivory Coast  

NASA Astrophysics Data System (ADS)

Since a half of century, the forest surface area of the South Ivory Coast has been decreased for the benefit of agriculture (15 000 km2 in 1993 versus 83 000 km2 in 1955-1958). This area also undergoes climate change. Vegetation cover has gradually changed from rainforests (C3 plants) to savanna (C4 plants) and agricultural plants. In the Abidjan area (5.00-6.00°N, 2.40-4.40°W), the mean rainfall amount and temperature value evolve during the 20th century (1912 mm/year and 26.3°C/year during the first decennial to 1613 mm/year and 26.9°C/year during the last ten years). The Paleoproterozoïc fractured bedrock (PB) and the Continental Terminal (CT) deposits groundwater are studied to show the climate change and deforestation effect on the area groundwater resources using stable isotopes (18O, 2H and 13C) contents, radiocarbon (14C) contents and chemical data on a set of 25 groundwater samples. The residence time of the groundwaters is estimated by the 14C using two models: (i) the model of well-mixed reservoir (WMR model) and (ii) the piston flow model (PF model). The range of the PB groundwater residence time (15 000 - 8 000 to ~ 300 - 100 a BP) for both models shows that the recharge has started at the beginning of the post-glacial period whereas the CT aquifer recharge is much more recent (from 300 a BP to today). The PB groundwater provides information about paleoclimatic conditions that occurred over the studied area during the late Pleistocene. It is demonstrated, through this study, that the evolution of vegetation cover (from forests to savanna and agriculture plants) is shown in groundwater by the trend in 13C content from old groundwater (confined bedrock groundwater: residence time of ~ 15 000 a BP) to the recent groundwater (unconfined bedrock groundwater and CT groundwater: residence times: ~ 300 a BP and lower than 100 a BP, respectively). The ?18O and ?2H values also increase with time from the beginning of the post-glacial period (~ 15 000 a BP) to the present day (< 100 a BP), showing the evolution of the climate from cold to warm conditions. This study has shown the paleoclimate effect on the water resources in Ivory Coast and are consistent with the results obtained by some authors in Western Africa (Ghana, Liberia, Mali and Niger).

Age of the Australasian Tektite Strewn Field  

NASA Astrophysics Data System (ADS)

As Fig. 1 shows, the widespread belief that the age of the Australasian tektite strewn field (AATSF) is ~0.7 m.y. appeared to be conventional. Tektites of different fission-track ages were found within the AATSF: 0.83 m.y. [1], 3.54-4.25 m.y. [2], and ~11 m.y. [3]. The first systematic investigation of the tektites, which were collected from a single stratigraphic layer in Vietnam, revealed three statistically discrete tektite age groups: 0.4, 0.6, and 0.8 m.y. [4]. Similar tektites 0.75 m.y. and 1.1 m.y. in age are typical of the Zhamanshin impact crater, which represents an eminent part of the AATSF [5]. Fig. 1, which appears here in the hard copy, shows radiogenic dating: 1-2: AATSF; 3-4: Zhamanshin; 1,3: data with known annealing correction. Compiled after Zahringer, 1963; Fleischer and Price, 1964; Gentner et al., 1969; McDougal and Lovering, 1969; Fleischer et al., 1969; Storzer and Wagner, 1979, 1980; Watanabe et al., 1985; Virk, 1985; Shukolukov et al., 1986; Kashkarov et al, 1986, 1987; Kolesnikov et al., 1987; Storzer and Muller-Sonhius, 1986; Arakelyants et al., 1988; etc. The very young geological age of the AATSF was established in Australia, and was confirmed by the author in Vietnam and in the Zhamanshin impact crater. This well-known tektite age paradox strongly supports an extraterrestrial origin of tektites. The paradox is fatal to the currently dominating Earth- impact theory of tektite origin, and we are not surprised that there are no continued attempts to either silence or disavow its significance. As a matter of fact, the formation of the gigantic AATSF can be considered as the main reason for the abrupt catastrophic climatic global changes and mass extinction of species on the Pleistocene/Holocene boundary 10,000 years ago [5,6]. The age-paradox scope dictates that tektites have been periodically formed and accumulated somewhere on an as-yet-unknown planetary body and then delivered to the Earth. The extraterrestrial volcanic eruptions seem to be the most appropriate process of the tektite formation and launching [7]. The frequent shift of the K-Ar ages relative to the fission-track ages of tektites can be explained by the presence of an extra argon inherited from some older crystalline inclusions foreign to the tektite glass. These inclusions are most common to the Muong Nong-type layered tektites and to flanges of the button-shape australites, and can be considered as an extraterrestrial environmental dust peppering.

An Ordinary Chondrite Impactor Composition for the Bosumtwi Impact Structure, Ghana, West Africa: Discussion of Siderophile Element Contents and Os and Cr Isotope Data  

NASA Technical Reports Server (NTRS)

Osmium isotope data had shown that Ivory Coast tektites contain an extraterrestrial component, but do not allow distinction between chondritic and iron meteorite contamination. PGE abundances of Ivory Coast tektites and impactites and target rocks from the Bosumtwi crater, the source crater of the Ivory Coast tektites, were all relatively high and did not allow to resolve the presence, or identify the nature, of the meteoritic component. However, Cr isotope analyses of an Ivory Coast tektite yielded a distinct 53Cr excess of 0.30+/-0.06, which indicates that the Bosumtwi impactor was an ordinary chondrite.

Full-Length Genome Characterization of a Novel Simian Immunodeficiency Virus Lineage (SIVolc) from Olive Colobus (Procolobus verus) and New SIVwrcPbb Strains from Western Red Colobus (Piliocolobus badius badius) from the Taï Forest in Ivory Coast?  

PubMed Central

Simian immunodeficiency viruses (SIVs) are found in an extensive number of African primates and humans continue to be exposed to these viruses by hunting and handling of primate bushmeat. Full-length genome sequences were obtained from SIVs derived from two Colobinae species inhabiting the Taï forest, Ivory Coast, each belonging to a different genus: SIVwrc from western red colobus (Piliocolobus badius badius) (SIVwrcPbb-98CI04 and SIVwrcPbb-97CI14) and SIVolc (SIVolc-97CI12) from olive colobus (Procolobus verus). Phylogenetic analysis showed that western red colobus are the natural hosts of SIVwrc, and SIVolc is also a distinct species-specific lineage, although distantly related to the SIVwrc lineage across the entire length of its genome. Overall, both SIVwrc and SIVolc, are also distantly related to the SIVlho/sun lineage across the whole genome. Similar to the group of SIVs (SIVsyk, SIVdeb, SIVden, SIVgsn, SIVmus, and SIVmon) infecting members of the Cercopithecus genus, SIVs derived from western red and olive colobus, L'Hoest and suntailed monkeys, and SIVmnd-1 from mandrills form a second group of viruses that cluster consistently together in phylogenetic trees. Interestingly, the divergent SIVcol lineage, from mantled guerezas (Colobus guereza) in Cameroon, is also closely related to SIVwrc, SIVolc, and the SIVlho/sun lineage in the 5? part of Pol. Overall, these results suggest an ancestral link between these different lentiviruses and highlight once more the complexity of the natural history and evolution of primate lentiviruses.

3-D laser images of splash-form tektites and their use in aerodynamic numerical simulations of tektite formation  

NASA Astrophysics Data System (ADS)

Ten splash-form tektites from the Australasian strewn field, with masses ranging from 21.20 to 175.00 g and exhibiting a variety of shapes (teardrop, ellipsoid, dumbbell, disk), have been imaged using a high-resolution laser digitizer. Despite challenges due to the samples' rounded shapes and pitted surfaces, the images were combined to create 3-D tektite models, which captured surface features with a high fidelity (?30 voxel mm-2) and from which volume could be measured noninvasively. The laser-derived density for the tektites averaged 2.41 ± 0.11 g cm-3. Corresponding densities obtained via the Archimedean bead method averaged 2.36 ± 0.05 g cm-3. In addition to their curational value, the 3-D models can be used to calculate the tektites' moments of inertia and rotation periods while in flight, as a probe of their formation environment. Typical tektite rotation periods are estimated to be on the order of 1 s. Numerical simulations of air flow around the models at Reynolds numbers ranging from 1 to 106 suggest that the relative velocity of the tektites with respect to the air must have been <10 m s-1 during viscous deformation. This low relative velocity is consistent with tektite material being carried along by expanding gases in the early time following the impact.

The water, deuterium, gas and uranium content of tektites

The water content, deuterium concentration of the water, total gas and uranium contents were determined on tektite samples and other glass samples from Texas, Australia, Philippine Islands, Java, French Indo-China, Czechoslovakia, Libyan Desert, Billiton Island, Thailand, French West Africa, Peru, and New Mexico. The water content ranges from 0.24 per cent for the Peru tektite, to 0.0002 per cent for a moldavite. The majority of the tektites have less than 0.05 per cent water, and average 0.005 per cent H2O by weight. No other gases were detected, the lower detection limit being about 1 p.p.m. by weight. The deuterium content of the water in tektites is in the same range as that in terrestrial waters, and varies from 0.010 mole per cent to 0.0166 mole per cent deuterium. The uranium content is about from 1 to 3 p.p.m. The possible origin of tektites is discussed. The experimental data presented favour their being originally terrestrial, but produced by some catastrophic event. An extra-terrestrial source is not ruled out. ?? 1958.

Beryllium-10 in Australasian tektites - Evidence for a sedimentary precursor  

NASA Technical Reports Server (NTRS)

Each of seven Australasian tektites contains about 100 micron atoms of beryllium-10 (half-life, 1.53 million years) per gram. Cosmic-ray bombardment of the australites cannot have produced the measured amounts of beryllium-10 either at the earth's surface or in space. The beryllium-10 contents of these australites are consistent with a sedimentary precursor that adsorbed from precipitation beryllium-10 produced in the atmosphere. The sediments must have spent several thousand years at the earth's surface within a few million years of the tektite-producing event.

A review of volatile compounds in tektites, and carbon content and isotopic composition of moldavite glass  

NASA Astrophysics Data System (ADS)

Tektites, natural silica-rich glasses produced during impact events, commonly contain bubbles. The paper reviews published data on pressure and composition of a gas phase contained in the tektite bubbles and data on other volatile compounds which can be released from tektites by either high-temperature melting or by crushing or milling under vacuum. Gas extraction from tektites using high-temperature melting generally produced higher gas yield and different gas composition than the low-temperature extraction using crushing or milling under vacuum. The high-temperature extraction obviously releases volatiles not only from the bubbles, but also volatile compounds contained directly in the glass. Moreover, the gas composition can be modified by reactions between the released gases and the glass melt. Published data indicate that besides CO2 and/or CO in the bubbles, another carbon reservoir is present directly in the tektite glass. To clarify the problem of carbon content and carbon isotopic composition of the tektite glass, three samples from the Central European tektite strewn field—moldavites—were analyzed. The samples contained only 35-41 ppm C with ?13C values in the range from -28.5 to -29.9‰ VPDB. This indicates that terrestrial organic matter was a dominant carbon source during moldavite formation.

Dissecting the Illegal Ivory Trade: An Analysis of Ivory Seizures Data  

PubMed Central

Reliable evidence of trends in the illegal ivory trade is important for informing decision making for elephants but it is difficult to obtain due to the covert nature of the trade. The Elephant Trade Information System, a global database of reported seizures of illegal ivory, holds the only extensive information on illicit trade available. However inherent biases in seizure data make it difficult to infer trends; countries differ in their ability to make and report seizures and these differences cannot be directly measured. We developed a new modelling framework to provide quantitative evidence on trends in the illegal ivory trade from seizures data. The framework used Bayesian hierarchical latent variable models to reduce bias in seizures data by identifying proxy variables that describe the variability in seizure and reporting rates between countries and over time. Models produced bias-adjusted smoothed estimates of relative trends in illegal ivory activity for raw and worked ivory in three weight classes. Activity is represented by two indicators describing the number of illegal ivory transactions – Transactions Index – and the total weight of illegal ivory transactions – Weights Index – at global, regional or national levels. Globally, activity was found to be rapidly increasing and at its highest level for 16 years, more than doubling from 2007 to 2011 and tripling from 1998 to 2011. Over 70% of the Transactions Index is from shipments of worked ivory weighing less than 10 kg and the rapid increase since 2007 is mainly due to increased consumption in China. Over 70% of the Weights Index is from shipments of raw ivory weighing at least 100 kg mainly moving from Central and East Africa to Southeast and East Asia. The results tie together recent findings on trends in poaching rates, declining populations and consumption and provide detailed evidence to inform international decision making on elephants.

The pre-edge peak intensities of tektites are 10.7-11.7%, and those of peudotachylite, Kirauea volcanic glass, impactite, pitchstone and perlite are 6.7-10.9%. The main peak shoulder intensities of tektites are 68.3-70.7%, and other natural glasses are 63.0-63.9%. XAFS analysis indicated all tektites possess 7-coordinated Ca, but natural glasses possess 6-, 7- and 8- coordinated Ca. This study indicated that different petrogenesis of natural glasses gives different local structures of calcium.

The trace element content and distribution in ivory from elephants and hippopotami were measured for both natural elements and elements present due to pollution. The National Accelerator Centre Nuclear Microprobe was used to investigate trace elements heavier than Ca, and distributions of these trace elements were measured over small areas (ca. 1 mm 2), using the Dynamic Analysis imaging method in the GeoPIXE software package. Quantitativity of elemental maps was checked by complementary point analyses in the same area as where the elemental maps were taken from and found to be accurate to within around 10%. The possibility of locating ivory on the basis of the trace element concentrations, determined by the environment in which these animals live, was demonstrated by using correspondence analysis.

Evidence for the formation of pools of melt free of unmelted clasts has not been reported for the well-studied terrestrial craters such as Manicouagan or Ries. It is suggested that large amounts of relict-free melt were produced only when a sizeable fraction of the cratered target consisted of dry, high-porosity materials such as aeolian sediments. Since dry, high-porosity target materials are always confined to the outer 100 to 200 m of the Earth, the fraction of melt produced melt is probably higher in small (radius 50 to 500 m) craters than in large (r greater than 1 km) craters. Another reason to infer that the Southeast Asian tektites were produced in a multitude of small craters is the wide distribution of layered tektites. The file spans at least 1200 km, which would require ballistic ejection at velocities greater than 2 km s(-1) if all melt was generated in a single crater. It seems impossible to devise a scenario that would lead to the deposition of primary melt as a crystal-free pool at a distance of 600 km from the crater.

The chemical durability of tektites - A laboratory study and correlation with long-term corrosion behavior  

NASA Technical Reports Server (NTRS)

Leach tests carried out on tektite specimens (indochinites and australites) under high-dilution conditions show a common behavior characterized by low leach rates (0.00018 g/sq m per d, or 7.2 x 10 to the -12th m/d at 23 C) and an activation energy of (79,600 + or - 700 J/mol). The extent of selective leaching is very small, of the order of 10 to the -8th m. Extrapolation of test results over the lifetime of the tektites gives an excellent agreement with field observations on the extent of corrosion, and this is an important step in establishing the validity of laboratory tests as a basis for the development of models and predictions concerning long-term durabilities at least in the limiting case of high dilution or rapid flow. The results are also shown to be in agreement with various previous observations on the corrosion resistance of tektites. The chemical durability of tektites is observed to be consistent with their composition, highlighting requirements of high corrosion resistance in glasses; these requirements include a silica content in excess of 67 mol percent, an extremely low water content, and an alkali content which is low both absolutely and relative to the di- and poly-valent metal oxide levels. It is shown that artificial glasses which fulfil these criteria are no less corrosion-resistant than the corresponding natural glasses. These conclusions have bearing on the development, as well as on the evaluation, of glasses intended for very long service, such as radioactive waste vitrification media.

Preliminary discussion on the origin of Lei-gong-mo (tektites)  

NASA Technical Reports Server (NTRS)

The specimens of lei-gong-mo (tektites) were collected from Hainan Island and Leizhow Peninsula during the period from 1963 to 1975. The distribution, forms, sculpture, abration surface (bald spot), internal structure and chemical composition of lei-gong-mo are discussed. Studies of these materials lead to the following conclusions: (1) the specimens of lei-gong-mo can be morphologically divided into eight types; (2) the sculptures on the surface of lei-gong-mo are probably due to the corrosion effect of volcanic gas, and the abration surface due to the aerodynamic corrosion; (3) the folded structures in the layered lei-gong-mo (Muong Nong-type tektite) seem hardly to be formed by an impact of meteorites, but they might be produced in the magma flow process when the lei-gong-mo was melting within the crater vent; and (4) the comparison of its chemical composition with that of basalt from Hainan Island does not show that lei-gong-mo came from the local volcano. The hypothesis of the lunar volcanic origin of tektites is examined.

Age and provenance of the target materials for tektites and possible impactites as inferred from Sm-Nd and Rb-Sr systematics  

NASA Technical Reports Server (NTRS)

Chemical, trace element, and isotopic compositions of tektites are consistent with production by melting of sediments derived from the old terrestrial continental crust. Each tektite group is characterized by a uniform Nd model age, interpreted as the time of formation of the crustal segment which weathered to form the parent sediment for the tektites. Sr model ages are variable within each group, reflecting Rb-Sr fractionation, and, in the favorable limit of very high Rb/Sr ratios, approach the time of sedimentation of the parent material which melted to form the tektites. Unlike tektites, which are dense homogeneous objects, sanidine spherules are porous, fine grained inhomogeneous objects. The leaching experiment employed by the present study shows that the sanidine spherules could have been formed by an oceanic impact involving basaltic crust and overlying sediments or seawater.

Tektites in Cretaceous-Tertiary boundary rocks on Haiti and their bearing on the Alvarez impact extinction hypothesis

Relic tektites are associated with a Pt-group metal abundance anomaly and shocked minerals in a thin marl bed that marks the K-T boundary on Haiti. The presence of these three impact-produced materials at the precise K-T boundary enormously strengthens the Alvarez impact extinction hypothesis. The Haitian tektites are the first datable impact products in K-T boundary rocks, and 40Ar-39Ar ages of the glass show that the K-T boundary and impact event are coeval at 64.5 ?? 0.1 Ma. -from Author

Meteoroid mayhem in Ole Virginny: source of the North American tektite strewn field  

USGS Publications Warehouse

New seismic reflection data from Chesapeake Bay reveal a buried, 85-km-wide, 1.5-2.0-km-deep, peak-ring impact crater, carved through upper Eocene to Lower Cretaceous sedimentary strata and into underlying pre-Mesozoic crystalline basement rocks. A polymictic, late Eocene impact breccia, composed mainly of locally derived sedimentary debris (determined from four continuous cores), surrounds and partly fills the crater. Structural and sedimentary characteristics of the Chesapeake Bay crater closely resemble those of the Miocene Ries peak-ring crater in southern Germany. It is speculated that the Chesapeake Bay crater is the source of the North American tektite strewn field. -Authors

Illegal killing for ivory drives global decline in African elephants  

PubMed Central

Illegal wildlife trade has reached alarming levels globally, extirpating populations of commercially valuable species. As a driver of biodiversity loss, quantifying illegal harvest is essential for conservation and sociopolitical affairs but notoriously difficult. Here we combine field-based carcass monitoring with fine-scale demographic data from an intensively studied wild African elephant population in Samburu, Kenya, to partition mortality into natural and illegal causes. We then expand our analytical framework to model illegal killing rates and population trends of elephants at regional and continental scales using carcass data collected by a Convention on International Trade in Endangered Species program. At the intensively monitored site, illegal killing increased markedly after 2008 and was correlated strongly with the local black market ivory price and increased seizures of ivory destined for China. More broadly, results from application to continental data indicated illegal killing levels were unsustainable for the species between 2010 and 2012, peaking to ?8% in 2011 which extrapolates to ?40,000 elephants illegally killed and a probable species reduction of ?3% that year. Preliminary data from 2013 indicate overharvesting continued. In contrast to the rest of Africa, our analysis corroborates that Central African forest elephants experienced decline throughout the last decade. These results provide the most comprehensive assessment of illegal ivory harvest to date and confirm that current ivory consumption is not sustainable. Further, our approach provides a powerful basis to determine cryptic mortality and gain understanding of the demography of at-risk species. PMID:25136107

Trace-element composition of Chicxulub crater melt rock, K/T tektites and Yucatan basement  

NASA Technical Reports Server (NTRS)

The Cretaceous/Tertiary (K/T) boundary Chicxulub impact is the best preserved large impact in the geologic record. The Chicxulub crater has been buried with no apparent erosion of its intracrater deposits, and its ejecta blanket is known and is well preserved at hundreds of localities globally. Although most of the molten material ejected from the crater has been largely altered, a few localities still preserve tektite glass. Availability of intra- and extracrater impact products as well as plausible matches to the targeted rocks allows the comparison of compositions of the different classes of impact products to those of the impacted lithologies. Determination of trace-element compositions of the K/T tektites, Chicxulub melt rock, and the targeted Yucatan silicate basement and carbonate/evaporite lithologies have been made using instrumental neutron activation analysis (INAA) and inductively coupled plasma mass spectrometry (ICP-MS). Some sample splits were studied with both techniques to ensure that inter-laboratory variation was not significant or could be corrected. The concentration of a few major and minor elements was also checked against microprobe results. Radiochemical neutron activation analysis (RNAA) was used to determine Ir abundances in some samples.

Petrographic and petrological studies of lunar rocks. [Apollo 15 breccias and Russian tektites

Clasts, rind glass, matrix glass, and matrix minerals from five Apollo 15 glass-coated breccias (15255, 15286, 15465, 15466, and 15505) were studied optically and with the SEM/microprobe. Rind glass compositions differ from sample to sample, but are identical, or nearly so, to the local soil, suggesting their origin by fusion of that soil. Most breccia samples contain green or colorless glass spheres identical to the Apollo 15 green glasses. These glasses, along with other glass shards and fragments, indicate a large soil component is present in the breccias. Clast populations include basalts and gabbros containing phases highly enriched in iron, indicative of extreme differentiation or fractional crystallization. Impact melts, anorthosites, and minor amounts of ANT suite material are also present among the clasts. Tektite glasses, impact melts, and breccias from the Zhamanshin structure, USSR, were also studied. Basic tektite glasses were found to be identical in composition to impact melts from the structure, but no satisfactory parent material has been identified in the limited suite of samples available.

Comparison of the magnetic properties and Mossbauer analysis of glass from the Cretaceous-Tertiary boundary, Beloc, Haiti, with tektites  

NASA Technical Reports Server (NTRS)

The magnetic properties of black Beloc glass have been measured. The Curie constant, the magnetization, and the magnetic susceptibility of the Beloc glass fall within the known ranges observed for tektites. However, the temperature-independent component of the magnetic susceptibility is slightly higher than that found for tektites. Moreover, it is not possible to match the experimental magnetic data for the Beloc glass with the calculated values using the previously reported Fe(3+)/Fe(2+) ratio of 0.7. The oxidation state of Fe was therefore redetermined by Mossbauer measurements, and the Fe(3+)/Fe(2+) ratio was found to be 0.024 plus or minus 0.015. Using the redetermined value of the ratio, the magnetic parameters were again calculated using formulas that are applicable to tektites, and good agreement was found between the calculated and experimental values. The experimental magnetic measurements and the redetermined Fe(3+)/Fe(2+) ratio of the Beloc glass specimens are essentially the same as those found for tektite glass.

57FE Mössbauer spectroscopy studies of Tektites from Khon Kaen, Ne Thailand  

NASA Astrophysics Data System (ADS)

Room temperature 57Fe Mössbauer effect spectroscopy has been used to investigate the local Fe environment in a set of indochinite tektites from Thailand. A MIMOS II spectrometer in backscattering geometry has been used in the study, so that no sample preparation at all was required. The spectra have been analysed in terms of discrete spectral components using Voigt functions. The results are similar to those obtained with analysis done with quadrupole splitting distributions. In all cases the Mössbauer spectra show a broadened asymmetric quadrupole split doublet. The Fe 2+ sites have been distinguished in Fe with octahedral and tetrahedral coordination. The Fe3+ /Fe2+ and Fe2+ tetrahedral/octahedral ratios have been determined from the relative areas of the various spectral components. Their values have been discussed in the light of actual literature.

Integrated water pollution assessment of the Ebrié Lagoon, Ivory Coast, West Africa  

NASA Astrophysics Data System (ADS)

An environmental pollution assessment of the Ebrié lagoon, the largest coastal ecosystem in Western Africa, was executed by applying the Driving force-Pressure-State-Impacts-Response (DPSIR) framework. The domestic and industrial activities in Abidjan and agricultural activities in the wider catchment area were identified as the main driving forces. Two-thirds of Biological Oxygen Demand (BOD) loads and 95% of total nitrogen (N) and phosphorous (P) loads of Abidjan are from domestic effluents, with industry making up the rest. Outside of the direct influence of Abidjan, nutrient levels in the lagoon are governed by the influx of nutrients from the rivers Comoé, Mé and Agnéby, with nutrient land runoff as the key factors. Total annual N loads to the lagoon for 2000 are estimated at 33 kt, of which 45% from urban sources, 42% from land runoff and 13% from atmospheric deposition. Estimates for P are 2.5 kt, 39%, 48% and 13%, respectively. Scenario analysis has shown that autonomous growth, without pollution reduction measures, would result in an estimated five-fold increase in nutrient inputs to the lagoon over the period 1980-2050. Nutrient concentrations in the lagoon would consequently increase by a factor of 3 1/2, which could escalate to a dramatic level of eutrophication for the complete system. Pollution reduction policies aimed at non-point sources would be most effective in reducing nutrient concentrations. Point-source pollution reduction would improve conditions around Abidjan, but not substantially in the other sections of the lagoon. The approach taken in this study has proven efficient under conditions of relative data scarceness, and sufficiently reliable to allow for policy level conclusions to be drawn.

The neoliberal elephant: Exploring the impacts of the trade ban in ivory on the commodification and neoliberalisation of elephants  

Microsoft Academic Search

This paper uses a case study that explores the impacts of the ivory trade ban on elephant management in Namibia to illuminate the processes and complexities associated with the commodification and neoliberalisation of nature. The paper demonstrates that the ivory trade ban neither prevents the commodification of elephants, nor hampers the neoliberalisation of nature. By tracing Namibia’s experience associated with

Intrinsic oxygen fugacity measurements on seven chondrites, a pallasite, and a tektite and the redox state of meteorite parent bodies  

USGS Publications Warehouse

Intrinsic oxygen-fugacity (fO2) measurements were made on five ordinary chondrites, a carbonaceous chondrite, an enstatite chondrite, a pallasite, and a tektite. Results are of the form of linear log fO2 - 1 T plots. Except for the enstatite chondrite, measured results agree well with calculated estimates by others. The tektite produced fO2 values well below the range measured for terrestrial and lunar rocks. The lowpressure atmospheric regime that is reported to follow large terrestrial explosions, coupled with a very high temperature, could produce glass with fO2 in the range measured. The meteorite Salta (pallasite) has low fO2 and lies close to Hvittis (E6). Unlike the other samples, results for Salta do not parallel the iron-wu??stite buffer, but are close to the fayalite-quartz-iron buffer in slope. Minor reduction by graphite appears to have taken place during metamorphism of ordinary chondrites. fO2 values of unequilibrated chondrites show large scatter during early heating suggesting that the constituent phases were exposed to a range of fO2 conditions. The samples equilibrated with respect to fO2 in relatively short time on heating. Equilibration with respect to fO2 in ordinary chondrites takes place between grades 3 and 4 of metamorphism. Application of P - T - fO2 relations in the system C-CO-CO2 indicates that the ordinary chondrites were metamorphosed at pressures of 3-20 bars, as it appears that they lay on the graphite surface. A steep positive thermal gradient in a meteorite parent body lying at the graphite surface will produce thin reduced exterior, an oxidized near-surface layer, and an interior that is increasingly reduced with depth; a shallow thermal gradient will produce the reverse. A body heated by accretion on the outside will have a reduced exterior and oxidized interior. Meteorites from the same parent body clearly are not required to have similar redox states. ?? 1984.

Sandy Coasts

Waves play a major role in breaking down and building up coastline features. But other factors, including tides, currents, and sediment type, also determine how erosional and depositional processes shape coastlines. This interactive feature introduces viewers to the landforms and features associated with sandy coasts. Typically located on passive margins in areas characterized by low wave energy, a wide continental shelf, and high offshore sediment influence, they develop depositional features such as extensive beaches and dunes, barrier islands, and sand spits.

Heat induced transformation of fossil mastodon ivory into turquoise 'odontolite'. Structural and elemental characterisation  

NASA Astrophysics Data System (ADS)

The present work deals with the structural and elemental analysis of turquoise mineral imitations as 'odontolite' or bone turquoise by transmission electron microscopy (TEM), scanning electron microscopy (SEM-EDX) and particle induced X-ray and ?-ray emission (PIXE-PIGE). The aim of the work is to evidence the former deliberate transformation of fossilised ivory by man in order to transform them into semi-precious stones. We show that the crystal structure of 'odontolite' artefacts consisting of fluorapatite (Ca 5(PO 4) 3F) corresponds to that of heated fossil mastodon ivory (12-15 million years old). Metallic traces detected by PIXE-PIGE in these 'odontolites' are discussed in order to explain their role for coloration. Other more greenish turquoise imitations have a bone-like structure and composition, and carbonate-hydroxylapatite. The presence of copper salts at the surface is responsible for their green coloration.

The identification of elephant ivory evidences of illegal trade with mitochondrial cytochrome b gene and hypervariable D-loop region.  

PubMed

DNA analysis of elephant ivory of illegal trade was handled in this work. The speciation and geographical origin of nine specimens of elephant ivory were requested by the police. Without national authorization, the suspect had purchased processed ivory seals from January to May, 2011 by Internet transactions from a site in a neighboring country. The DNA of decalcified ivory evidences was isolated with QIAGEN Micro Kit. The total 844-904 base pair sized sequences of mitochondrial cytochrome b and D-loop region could be acquired using direct sequencing analysis. They were compared with the sequences registered in GenBank. It was confirmed that most specimens were likely from African forest elephants (Loxodonta cyclotis), one from African savanna elephant (Loxodonta africana) and one from Asian elephant (Elephas maximus). Analysis of the mitochondrial hypervariable D-loop region sequence of elephants verified that one African savanna elephant might be from South Africa and one Asian elephant from Laos. Cytochrome b and D-loop region located in the mitochondrial DNA resulted in the successful determination of elephant DNA from nine processed ivory specimens. PMID:23472798

Coeval Ar-40/Ar-39 ages of 65.0 million years ago from Chicxulub crater melt rock and Cretaceous-Tertiary boundary tektites  

NASA Technical Reports Server (NTRS)

Ar-40/Ar-39 dating of drill-core samples of a glassy melt rock recovered from beneath a massive impact breccia contained with the 180-kilometer subsurface Chicxulub crater yields well-behaved incremental heating spectra with a mean plateau age of 64.98 +/- 0.05 million years ago (Ma). The glassy melt rock of andesitic composition was obtained from core 9 (1390 to 1393 meters) in the Chicxulub 1 well. The age of the melt rock is virtually indistinguishable from Ar-40/Ar-39 ages obtained on tektite glass from Beloc, Haiti, and Arroyo el Mimbral, northeastern Mexico, of 65.01 +/- 0.08 Ma (mean plateau age for Beloc) and 65.07 +/- 0.10 Ma (mean total fusion age for both sites). The Ar-40/Ar-39 ages, in conjunction with geochemical and petrological similarities, strengthen the suggestion that the Chicxulub structure is the source for the Haitian and Mexican tektites and is a viable candidate for the Cretaceous-Tertiary boundary impact site.

[Epidemiologic study of bluetongue in sheep, cattle and different species of wild animals in the Ivory Coast].  

PubMed

Between 1992 and 1993, a serological survey was conducted in Côte d'Ivoire on 623 sera from sheep, 215 sera from cattle and 211 sera from wild herbivores. These sera were tested for bluetongue virus (BTV) antibodies using an agar gel immunodiffusion test. The purpose of this survey was twofold: to establish the incidence of bluetongue in the country, and to analyse the putative role of BTV in the reproductive pathology of sheep. Seroprevalence was 52 +/- 4% in sheep, 95 +/- 3% in cattle, and 56 +/- 7% in wild herbivores. The authors found antibodies against BTV in kob (Kobus kob Erxleben, 1777), common waterbuck (Kobus ellipsiprymnus Ogilby, 1833), roan antelope (Hippotragus equinus Desmarest, 1804), buffalo (Syncerus caffer Sparrman, 1779), hartebeest (Alcelaphus buselaphus Pallas, 1766) and elephant (Loxodonta africana Blumenbach, 1797). A significant difference was found in seroprevalence in sheep between the three areas covered by the survey. Antibody prevalence increased significantly with age in sheep and wild herbivores, and seroprevalence was higher in dams with a history of abortion. It can therefore be concluded that bluetongue is enzootic in Côte d'Ivoire. PMID:7949349

Genital ulcers associated with human immunodeficiency virus-related immunosuppression in female sex workers in Abidjan, Ivory Coast.  

PubMed

A cross-sectional study among female sex workers in Abidjan was conducted to study the association between sexually transmitted diseases and human immunodeficiency virus (HIV) infection and HIV-related immunosuppression. Among 1209 women tested for HIV, 962 (80%) were seropositive. HIV infection was independently associated with a longer duration of sex work, a lower price for intercourse, being an immigrant, and having a positive Treponema pallidum hemagglutination test (P < .05). Genital ulcers (25% vs. 5%), genital warts (14% vs. 4%), Neisseria gonorrhoeae (32% vs. 16%), Trichomonas vaginalis (27% vs. 17%), and syphilis (27% vs. 17%) were more frequent (P < .05) in HIV-infected than -uninfected women. Among HIV-infected women, the proportions with a genital ulcer were 17%, 25%, and 36% for those with > 28%, 14%-28%, and < 14% CD4 cells, respectively (P < .001). This study suggests that genital ulcers are an opportunistic disease in female sex workers in Abidjan. PMID:7594681

Such formation process of AuNPs was shown to be responsible for purple stains naturally formed on Egyptianizing archaeological gilded ivories from 8th BC Syria. The understanding of this formation mechanism, which most likely involves a step with hybrid AuNPs, allows the establishing of an authenticity marker of ancient gold-plated ivories. PMID:24966058

Multi-component diffusion between molten SiO2 inclusions and surrounding felsic melt in an indochinite: Tektites as natural laboratories  

NASA Astrophysics Data System (ADS)

Tektites are natural glasses thought to have formed as a result of melting and quenching of distally ejected terrestrial material upon hypervelocity (>11 km/s) impact on Earth. Some tektites contain inclusions of lechatelierite (nearly pure SiO2 glass; 99-100 wt. % SiO2), generally thought to be the amorphous relicts of partially digested quartz grains (Koeberl, 1994). Electron and ion microprobe analyses of major and minor elements were performed on transects between lechatelierite inclusions and the surrounding felsic glass in an indochinite (sample from Newman et al., 1995). The surrounding glass is peraluminous with an average composition of 73.4 wt.% SiO2, 12.8 wt.% Al2O3, 4.5 wt. % FeO, 2.3 wt.% K2O, and < 2 wt.% (each) CaO, MgO, Na2O, and TiO2. The boundary between the lechatelierite and felsic glass is broad (~30 ?m), with complex concentration profiles reflecting diffusion between the two melts at high temperatures (>2200 °C for formation of lechatelierite; Bunch et al., 2012) prior to quenching. Although all components except SiO2 are pinned to near zero at the same point at the lechatelierite end of the profiles, the shapes of the oxide concentration profiles differ, with Ca and Mg falling off from their far-field values first, followed in order by Fe, Ti, Al, Na, and K. K has apparently propagated the longest distance, diffusing faster than other components from the surrounding melt toward the lechatelierite. Furthermore, concentration profiles of K2O systematically increase, reach a maximum, then decrease closest to lechatelierite, indicating uphill diffusion of K against its concentration gradient. All concentration profiles are asymmetric, becoming steepest towards the most silicic portions of the interdiffusion zone approaching lechatelierite, likely due to the sharp compositional contrast between matrix glass and inclusions. Sato (1974) observed similar alkali enrichment in coronas around quartz xenocrysts in basalt and andesite, where K, and to a lesser degree Na, diffused against their concentration gradients. The uphill diffusion of alkalis in corona glass surrounding quartz was interpreted by Sato (1974) with a diffusion model assuming non-ideality of alkali elements in silicate melt, in which diffusion occurs according to the chemical potential gradient of each species. Preliminary calculations using the MELTS (Ghiorso and Sack, 1995) activity-composition model to transform the composition profiles across lechatelierite and felsic glass into chemical potential profiles (at 2200 °C) indicate that all components, including K2O, diffuse down their own chemical potential gradients. We will investigate these phenomena further in attempt to model the observed profiles. A deeper understanding of this problem may inform the factors controlling diffusion coefficients in silicate melts derived from crustal material, as well as the thermal histories of tektites.

Video analysis of the escape flight of Pileated Woodpecker Dryocopus pileatus: does the Ivory-billed Woodpecker Campephilus principalis persist in continental North America?  

PubMed Central

Background The apparent rediscovery of the Ivory-billed Woodpecker Campephilus principalis in Arkansas, USA, previously feared extinct, was supported by video evidence of a single bird in flight (Fitzpatrick et al, Science 2005, 308:1460–1462). Plumage patterns and wingbeat frequency of the putative Ivory-billed Woodpecker were said to be incompatible with the only possible confusion species native to the area, the Pileated Woodpecker Dryocopus pileatus. Results New video analysis of Pileated Woodpeckers in escape flights comparable to that of the putative Ivory-billed Woodpecker filmed in Arkansas shows that Pileated Woodpeckers can display a wingbeat frequency equivalent to that of the Arkansas bird during escape flight. The critical frames from the Arkansas video that were used to identify the bird as an Ivory-billed Woodpecker are shown to be equally, or more, compatible with the Pileated Woodpecker. Conclusion The identification of the bird filmed in Arkansas in April 2004 as an Ivory-billed Woodpecker is best regarded as unsafe. The similarities between the Arkansas bird and known Pileated Woodpeckers suggest that it was most likely a Pileated Woodpecker. PMID:17362504

Phagocytosis and respiratory burst activity of haemocytes from the ivory snail, Babylonia areolata.  

PubMed

Haemocytes from the ivory snail, Babylonia areolata phagocytized Saccharomyces cerevisiae and Vibrio parahaemolyticus after 30 min. Haemocytes phagocytized V. parahaemolyticus at a greater rate than they phagocytized S. cerevisiae. The phagocytic rate (PP) of V. parahaemolyticus by granulocytes to was a little higher than that of S. cerevisiae. The phagocytic index (PI) of V. parahaemolyticus by granulocytes was significantly higher than that of S. cerevisiae. The same was true of hyalinocytes. The PP of granulocytes was significantly higher than that of hyalinocytes for each pathogen. No difference in PI was observed in granulocytes and hyalinocytes. Two defense mechanisms of B. areolata were quantified using flow cytometry. Haemocyte phagocytosis was quantified using fluorescent microbeads and respiratory burst activity was measured using H2O2 increases detected by 2', 7'-dichlorofluorescein diacetate. Both phagocytosis and respiratory burst activity of the haemocytes increased over time. After 90 min the phagocytic rate no longer increased. In the case of respiratory burst, the greatest increase in fluorescence occurred between 30 and 120 min, no further increase was seen after 120 min. These results showed unequivocally that a native (unstimulated) haemocyte oxidative burst was active in B. areolata. The aim of this study was to further the knowledge of immunology in gastropods.

Uncertain sightings and the extinction of the Ivory-billed Woodpecker.  

PubMed

The extinction of a species can be inferred from a record of its sightings. Existing methods for doing so assume that all sightings in the record are valid. Often, however, there are sightings of uncertain validity. To date, uncertain sightings have been treated in an ad hoc way, either excluding them from the record or including them as if they were certain. We developed a Bayesian method that formally accounts for such uncertain sightings. The method assumes that valid and invalid sightings follow independent Poisson processes and use noninformative prior distributions for the rate of valid sightings and for a measure of the quality of uncertain sightings. We applied the method to a recently published record of sightings of the Ivory-billed Woodpecker (Campephilus principalis). This record covers the period 1897-2010 and contains 39 sightings classified as certain and 29 classified as uncertain. The Bayes factor in favor of extinction was 4.03, which constitutes substantial support for extinction. The posterior distribution of the time of extinction has 3 main modes in 1944, 1952, and 1988. The method can be applied to sighting records of other purportedly extinct species. PMID:21967229

The aim of these measurements was to increase the age data base for Ries impact glasses directly from the Ries crater, because there is only one Ar-Ar step-heating spectrum available in the literature. Almost all samples display saddle-shaped age spectra, indicating the presence of excess argon in most Ries glass samples, most probably inherited argon from incompletely degassed melt and possibly also excess argon incorporated during cooling from adjacent phases. In contrast, moldavites usually contain no inherited argon, probably due to their different formation process implying solidification during ballistic transport. The plateau age of the only flat spectrum is 14.60 ± 0.16 (0.20) Ma (2?), while the total age of this sample is 14.86 ± 0.20 (0.22) Ma (isochron age: 14.72 ± 0.18 [0.22] Ma [2?]), proofing the chronological relationship of the Ries impact and moldavites. The total ages of the other samples range between 15.77 ± 0.52 and 20.4 ± 1.0 Ma (2?), implying approximately 2-40% excess 40Ar (compared to the nominal age of the Ries crater) in respective samples. Thus, the age of 14.60 ± 0.16 (0.20) (2?) (14.75 ± 0.16 [0.20 Ma] [2?], calculated using the most recent suggestions for the K decay constants) can be considered as reliable and is within uncertainties indistinguishable from the most recent compilation for the age of the moldavite tektites.

Impact of Tributyltin and Triphenyltin on Ivory Shell (Babylonia japonica) Populations  

PubMed Central

We histopathologically examined gonads and chemically determined organotin compounds in tissues of the ivory shell, Babylonia japonica. Imposex (a superimposition of male-type genital organs on females) occurred in approximately 80–90% of B. japonica specimens that we examined, with the penis and vas deferens both well developed. No oviduct blockage by vas deferens formation was observed. Ovarian spermatogenesis and suppressed ovarian maturation were observed in the females that exhibited imposex, although no histopathological abnormalities were found in males. Tissue distributions of organotin compounds [tributyltin (TBT), triphenyltin (TPhT), and their metabolites] were different for butyltins and phenyltins; a remarkably high accumulation of TBT was observed in the ctenidium, osphradium, and heart, whereas high concentrations of TPhT were detected in the ovary and digestive gland. More than one-third of TBT accumulated in the digestive glands of both males and females, followed by the testis, ctenidium, muscle, and heart tissues in males and in the muscle, ovary, ctenidium, and head tissues (including the central nervous system ganglia) in females. In both males and females, more than half of total TPhT accumulated in the digestive glands, followed by the gonads. The next highest values were in the muscle, ctenidium, and heart tissues in males and in the muscle, oviduct, and head tissues in females. Both TBT and TPhT concentrations in the gonads were positively correlated with penis length in females. Our findings strongly suggest that reproductive failure in adult females accompanied by imposex, possibly induced by TBT and TPhT from antifouling paints, may have caused the marked decline of B. japonica populations in Japan.

West Coast Chlorophyll Bloom  

NSDL National Science Digital Library

Sea-viewing Wide Field-of-view Sensor (SeaWiFS) on board the Orbview 2 satellite captured the phytoplankton bloom October 6, 2002 . Red represents high concentration of chlorophyll, follow by orange, yellow and green. Land and cloud portions of the image are presented in natural color. SeaWiFS monitors ocean plant life by measuring the amount of chlorophyll in the ocean. Large phytoplankton blooms tend to coincide with natural phenomena that drive that nutrient-rich water to the surface. The process is called upwelling. Winds coming off principal land masses push surface layers of water away from the shore. Into the resulting wind-driven void deeper water underneath the surface layers rushes in toward the coast, bringing with it nutrients for life to bloom. This upwelling fuel the growth of marine phytoplankton which, along with larger seaweeds, nourishes the incredible diversity of creatures found along the northern and central California coast.

Gone but not Forgotten? The Use of Airborne Laser Mapping in the Recovery Strategy for the Ivory-billed Woodpecker  

NASA Astrophysics Data System (ADS)

The reappearance of the ivory-billed woodpecker in 2004, long-thought to be extinct, has created considerable controversy. Millions of dollars have been spent in the subsequent search to provide confirmation of the sightings, and thus validate what would be one of the great avian rediscoveries of our time. Recent searches for the woodpecker in the Cache and White River National Wildlife Refuges in Arkansas by ground-based teams have failed to locate it. However, the area is immense, with many locations difficult to access on foot. Thus, there is the need for near-term habitat monitoring at the local scale to guide immediate search efforts, and near- and long-term landscape scale characterization and assessment, both to guide further search efforts and to delineate suitable potential habitat should a population be found. A joint research effort by the University of Maryland, the US Fish and Wildlife Service, NASA, and the US Geological Survey was initiated early this year with the goal of using airborne and satellite remote sensing for habitat characterization and monitoring consistent with the ivory-billed woodpecker recovery strategy. A centerpiece of this effort is the use of lidar remote sensing to map management factors such as canopy cover, basal area, tree stocking, height and biomass, all of which are difficult to retrieve by any other means. In June, the Laser Vegetation Imaging Sensor (LVIS) was used to map over 1 million hectares of potential habitat. In this paper we discuss our mapping efforts with particular focus on how these data are used to make maps of forest management factors, and how these maps may then be combined to highlight areas of particularly suitable woodpecker habitat.

Coasts In Crisis  

NSDL National Science Digital Library

This United States Geological Survey publication (Circular 1075) is the first of a planned group of monographs in a series called "Public Issues in Earth Science." It discusses the dangers posed to coasts and coastal communities by "development, recreation, and waste disposal," among other activities. It describes the ever changing nature of coastlines, and both the natural and human causes of coastal change. Four case studies are very briefly described. While not an exhaustive treatment of its subject, this is an effective introduction that may encourage further study. A small bibliography is provided.

Coasts in Crisis  

SciTech Connect

Coastal areas are staggering under an onslaught of human activity. We are presently in the process of destroying 70 percent of the world`s 600,000 square kilometers of coral reefs, an ecosystem containing some 200,000 different species and rivaling tropical rain forests in biodiversity. A combination of pollution, habitat destruction, and gross overfishing has led to the collapse of major fisheries and paved the way for malnutrition and disease in regions where people fish for subsistence. Globally, little is being done to manage the crisis of our coasts. Management strategies, if they exist at all, often deal with economic development along a wafer-thin strip of coastal land. Resource degradation is ignored, and watershed management is mostly rhetoric. Although some 55 countries have drawn up coastal management plans, only a handful have been properly implemented. Coasts must be managed in an integrated manner that takes into account the full range of human activities. Initiating this process is costly, time-consuming, and difficult. Yet we have more than three decades of accumulated experience to draw on.

A coasting cosmology  

NASA Technical Reports Server (NTRS)

A Friedmann-Robertson-Walker cosmology with energy density decreasing in expansion as 1/R-squared, where R is the Robertson-Walker scale factor, is studied. In such a model the universe expands with constant velocity; hence the term coasting cosmology. Observational consequences of such a model include the age of the universe, the luminosity distance-redshift relation (the Hubble diagram), the angular diameter distance-redshift relation, and the galaxy number count as a function of redshift. These observations are used to limit the parameters of the model. Among the interesting consequences of the model are the possibility of an ever-expanding closed universe, a model universe with multiple images at different redshifts of the same object, a universe with Omega - 1 not equal to 0 stable in expansion, and a closed universe with radius smaller than 1/H(0).

Honduras: Caribbean Coast.  

PubMed

The coast of Honduras, Central America, represents the southern end of the Mesoamerican Barrier Reef System, although its marine resources are less extensive and studied than nearby Belize and Mexico. However, the coastal zone contains mainland reef formations, mangroves, wetlands, seagrass beds and extensive fringing reefs around its offshore islands, and has a key role in the economy of the country. Like most tropical areas, this complex of benthic habitats experiences limited annual variation in climatic and oceanographic conditions but seasonal and occasional conditions, particularly coral bleaching and hurricanes, are important influences. The effects of stochastic factors on the country's coral reefs were clearly demonstrated during 1998 when Honduras experienced a major hurricane and bleaching event. Any natural or anthropogenic impacts on reef health will inevitably affect other countries in Latin America, and vice versa, since the marine resources are linked via currents and the functioning of the system transcends political boundaries. Much further work on, for example, movement of larvae and transfer of pollutants is required to delineate the full extent of these links. Anthropogenic impacts, largely driven by the increasing population and proportion of people living in coastal areas, are numerous and include key factors such as agricultural run-off, over-fishing, urban and industrial pollution (particularly sewage) and infrastructure development. Many of these threats act synergistically and, for example, poor watershed management via shifting cultivation, increases sedimentation and pesticide run-off onto coral reefs, which increases stress to corals already affected by decreasing water quality and coral bleaching. Threats from agriculture and fishing are particularly significant because of the size of both industries. The desire to generate urgently required revenue within Honduras has also led to increased tourism which provides an overarching stress to marine resources since most tourists spend time in the coastal zone. Hence the last decade has seen a dramatic increase in coastal development, a greater requirement for sewage treatment and more demand for freshwater, particularly in the Bay Islands. Although coastal zone management is relatively recent in Honduras, it is gaining momentum from both large-scale initiatives, such as the Ministry of Tourism's 'Bay Islands Environmental Management Project', and national and international NGO projects. For example, a series of marine protected areas and legislative regulations have been established, but management capacity, enforcement and monitoring are limited by funding, expertise and training. Existing and future initiatives, supported by increased political will and environmental awareness of stakeholders, are vital for the long-term economic development of the country. PMID:11827108

Red Tide off Texas Coast  

NASA Technical Reports Server (NTRS)

Red tides (algae) bloomed late this summer along a 300-mile stretch of Texas' Gulf Coast, killing millions of fish and shellfish as well as making some people sick. State officials are calling this the worst red tide bloom in 14 years. The algae produces a poison that paralyzes fish and prevents them from breathing. There is concern that the deadly algae could impact or even wipe out this year's oyster harvest in Texas, which usually peaks during the Thanksgiving and Christmas holidays. The red tides were first observed off the Texas coast in mid-August and have been growing steadily in size ever since. Red tides tend to bloom and subside rapidly, depending upon changes in wind speed and direction, water temperature, salinity, and rainfall patterns (as the algae doesn't do as well in fresher water). This true-color image of the Texas Gulf Coast was acquired on September 29, 2000, by the Moderate-resolution Imaging Spectroradiometer (MODIS) flying aboard NASA's Terra spacecraft. The red tide can be seen as the dark reddish discoloration in the ocean running southwest to northeast along the coast. In this scene, the bloom appears to be concentrated north and east of Corpus Christi, just off Matagorda Island. The image was made at 500-meter resolution using a combination of MODIS' visible bands 1 (red), 4 (green), and 3 (blue). The city of Houston can be seen clearly as the large, greyish cluster of pixels to the north and west of Galveston Bay, which is about mid-way up the coastline in this image. Also visible in this image are plumes of smoke, perhaps wildfires, both to the north and northeast of Houston. For more information about red tides, refer to the Texas Red Tide Web site.

Traditional West Coast Native Medicine  

PubMed Central

An important part of the complex culture of the Native people of Canada's Pacific coast is the traditional system of medicine each culture has developed. Population loss from epidemics and the influence of dominant European cultures has resulted in loss of many aspects of traditional medicine. Although some Native practices are potentially hazardous, continuation of traditional approaches to illness remains an important part of health care for many Native people. The use of “devil's club” plant by the Haida people illustrates that Native medicine has both spiritual and physical properties. Modern family practice shares many important foundations with traditional healing systems. PMID:21253031

West Coast Tsunami: Cascadia's Fault?  

NASA Astrophysics Data System (ADS)

The tragedies of 2004 Sumatra and 2011 Japan tsunamis exposed the limits of our knowledge in preparing for devastating tsunamis. The 1,100-km coastline of the Pacific coast of North America has tectonic and geological settings similar to Sumatra and Japan. The geological records unambiguously show that the Cascadia fault had caused devastating tsunamis in the past and this geological process will cause tsunamis in the future. Hypotheses of the rupture process of Cascadia fault include a long rupture (M9.1) along the entire fault line, short ruptures (M8.8 - M9.1) nucleating only a segment of the coastline, or a series of lesser events of M8+. Recent studies also indicate an increasing probability of small rupture occurring at the south end of the Cascadia fault. Some of these hypotheses were implemented in the development of tsunami evacuation maps in Washington and Oregon. However, the developed maps do not reflect the tsunami impact caused by the most recent updates regarding the Cascadia fault rupture process. The most recent study by Wang et al. (2013) suggests a rupture pattern of high- slip patches separated by low-slip areas constrained by estimates of coseismic subsidence based on microfossil analyses. Since this study infers that a Tokohu-type of earthquake could strike in the Cascadia subduction zone, how would such an tsunami affect the tsunami hazard assessment and planning along the Pacific Coast of North America? The rapid development of computing technology allowed us to look into the tsunami impact caused by above hypotheses using high-resolution models with large coverage of Pacific Northwest. With the slab model of MaCrory et al. (2012) (as part of the USGS slab 1.0 model) for the Cascadia earthquake, we tested the above hypotheses to assess the tsunami hazards along the entire U.S. West Coast. The modeled results indicate these hypothetical scenarios may cause runup heights very similar to those observed along Japan's coastline during the 2011 Japan tsunami,. Comparing to a long rupture, the Tohoku-type rupture may cause more serious impact at the adjacent coastline, independent of where it would occur in the Cascadia subduction zone. These findings imply that the Cascadia tsunami hazard may be greater than originally thought.

Southwest coast of Greenland and Davis Strait  

NASA Technical Reports Server (NTRS)

This true-color image was taken by MODIS as it passed over the southwest coast of Greenland (right) and the Davis Strait (center and left). The Davis Strait connects Baffin Bay to the north and the Labrador Sea to the south, and separates Greenland from Baffin Island, Canada. The Davis Strait is part of the Northwest Passage, a navigable seaway connecting the Atlantic Ocean and the Pacific Ocean. The image shows the prevailing currents in the area, with the warm water of a branch of the North Atlantic Drift flowing northward along the Greenland coast, and the cold, iceberg-filled Labrador Current flowing southward along the Baffin Island coast.

Fluctuations of cambial activity in relation to precipitation result in annual rings and intra-annual growth zones of xylem and phloem in teak (Tectona grandis) in Ivory Coast  

PubMed Central

Background and Aims Teak forms xylem rings that potentially carry records of carbon sequestration and climate in the tropics. These records are only useful when the structural variations of tree rings and their periodicity of formation are known. Methods The seasonality of ring formation in mature teak trees was examined via correlative analysis of cambial activity, xylem and phloem formation, and climate throughout 1·5 years. Xylem and phloem differentiation were visualized by light microscopy and scanning electron microscopy. Key Results A 3 month dry season resulted in semi-deciduousness, cambial dormancy and formation of annual xylem growth rings (AXGRs). Intra-annual xylem and phloem growth was characterized by variable intensity. Morphometric features of cambium such as cambium thickness and differentiating xylem layers were positively correlated. Cambium thickness was strongly correlated with monthly rainfall (R2 = 0·7535). In all sampled trees, xylem growth zones (XGZs) were formed within the AXGRs during the seasonal development of new foliage. When trees achieved full leaf, the xylem in the new XGZs appeared completely differentiated and functional for water transport. Two phloem growth rings were formed in one growing season. Conclusions The seasonal formation pattern and microstructure of teak xylem suggest that AXGRs and XGZs can be used as proxies for analyses of the tree history and climate at annual and intra-annual resolution.

South coast air quality management district  

SciTech Connect

The first of several state-of-the-art sampling instruments to monitor acid fog in the South Coast Air Basin on an on-going basis has been in stalled in Rubidoux by the South Coast Air Quality Management District. The automated equipment, called the Caltech Active Strand Collector (CASC), is part of a long-term acid fog monitoring program developed by AQMD. The collecting process involves drawing a fog-laden air sample into the collector where fog droplets strike a series of teflon strands and run down to a collection trough. The sample is then sent to AQMD's laboratory to determine acidity and chemical composition. The monitoring equipment will be moved to Pomona later this winter, and to Crestline in the spring. Following this initial evaluation period, additional CASC units will be sited in the region.

WEST COAST REGIONAL CARBON SEQUESTRATION PARTNERSHIP  

SciTech Connect

The West Coast Regional Carbon Sequestration Partnership is one of seven partnerships which have been established by the US Department of Energy (DOE) to evaluate carbon dioxide capture, transport and sequestration (CT&S) technologies best suited for different regions of the country. The West Coast Region comprises Arizona, California, Nevada, Oregon, Washington, and the North Slope of Alaska. Led by the California Energy Commission, the West Coast Partnership is a consortium of over thirty five organizations, including state natural resource and environmental protection agencies; national labs and universities; private companies working on CO{sub 2} capture, transportation, and storage technologies; utilities; oil and gas companies; nonprofit organizations; and policy/governance coordinating organizations. In an eighteen month Phase I project, the Partnership will evaluate both terrestrial and geologic sequestration options. Work will focus on five major objectives: (1) Collect data to characterize major CO{sub 2} point sources, the transportation options, and the terrestrial and geologic sinks in the region, and compile and organize this data via a geographic information system (GIS) database; (2) Address key issues affecting deployment of CT&S technologies, including storage site permitting and monitoring, injection regulations, and health and environmental risks (3) Conduct public outreach and maintain an open dialogue with stakeholders in CT&S technologies through public meetings, joint research, and education work (4) Integrate and analyze data and information from the above tasks in order to develop supply curves and cost effective, environmentally acceptable sequestration options, both near- and long-term (5) Identify appropriate terrestrial and geologic demonstration projects consistent with the options defined above, and create action plans for their safe and effective implementation A kickoff meeting for the West Coast Partnership was held on Sept 30-Oct.1. Contracts were then put into place with twelve organizations which will carry out the technical work required to meet Partnership objectives.

Oceanic rainfall off the Pacific Northwest Coast  

NASA Astrophysics Data System (ADS)

Rainfall within 55 km of the northwest coast of the United States was measured from a buoy and estimated from weather reports at lightships. Results show that precipitation at sea was only about one half to one third of that found at coastal land stations. Rainfall typically occurs both at sea and on shore on the same days but for fewer hours at sea. The relative amount at sea seems to vary with the type of atmospheric system producing the rainfall.

Tritium level along Romanian Black Sea Coast  

SciTech Connect

Establishing the tritium level along the Romanian Black Sea Coast, after 10 years of exploitation of the nuclear power plant from Cernavoda, is a first step in evaluating its impact on the Black Sea ecosystem. The monitoring program consists of tritium activity concentration measurement in sea water and precipitation from Black Sea Coast between April 2005 and April 2006. The sampling points were spread over the Danube-Black Sea Canal - before the locks Agigea and Navodari, and Black Sea along the coast to the Bulgarian border. The average tritium concentration in sea water collected from the sampling locations had the value of 11.1 {+-} 2.1 TU, close to tritium concentration in precipitation. Although an operating nuclear power plant exists in the monitored area, the values of tritium concentration in two locations are slightly higher than those recorded elsewhere. To conclude, it could be emphasized that until now, Cernavoda NPP did not had any influence on the tritium concentration of the Black Sea Shore. (authors)

Comparison of somatic reversions between the ivory allele and transposon-caused mutant alleles at the white locus of Drosophila melanogaster after larval treatment with X rays and ethyl methanesulfonate  

SciTech Connect

Somatic reversion of strains with the ivory (wi) allele, a mutation associated with a tandem duplication of a DNA sequence at the white locus, increased with the age of larvae at the time of X-irradiation as expected from the increase in the number of target cells. In contrast, two independently isolated strains with unstable w+ loci associated with insertion of transposable elements showed higher reversion frequencies after treatment with X rays or ethyl methanesulfonate (EMS) at early larval stages than at late stages. Nevertheless, both the wi strain and the two unstable w+ strains reverted at nearly equal rates after treatment with X rays or EMS at early larval stages. Possible similarity in hot spot structure for the high reversibility of the two types of mutations is discussed in relation to production of presumed mutator-type cofactors specific to the transposon-caused mutations at early larval stages.

Coastal Fog, South Peruvian Coast at Pisco  

NASA Technical Reports Server (NTRS)

Coastal fog commonly drapes the Peruvian coast. This image captures complex interactions between land, sea, and atmosphere along the southern Peruvian coast. When Shuttle astronauts took the image in February of 2002, the layers of coastal fog and stratus were being progressively scoured away by brisk south to southeast winds. Remnants of the cloud deck banked against the larger, obstructing headlands like Peninsula Paracas and Isla Sangayan, giving the prominent 'white comma' effect. Southerlies also produced ripples of internal gravity waves in the clouds offshore where warm, dry air aloft interacts with a thinning layer of cool, moist air near the sea surface on the outer edge of the remaining cloud bank. South of Peninsula Baracas, the small headlands channeled the clouds into streaks-local horizontal vortices caused by the headlands provided enough lift to give points of origin of the clouds in some bays. Besides the shelter of the peninsula, the Bahia de Pisco appears to be cloud-free due to a dry, offshore flow down the valley of the Rio Ica. The STS-109 crew took image STS109-730-80 in February 2002. The image is 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.

Assessing hazards along our Nation's coasts  

USGS Publications Warehouse

Coastal areas are essential to the economic, cultural, and environmental health of the Nation, yet by nature coastal areas are constantly changing due to a variety of events and processes. Extreme storms can cause dramatic changes to our shorelines in a matter of hours, while sea-level rise can profoundly alter coastal environments over decades. These changes can have a devastating impact on coastal communities, such as the loss of homes built on retreating sea cliffs or protective dunes eroded by storm waves. Sometimes, however, the changes can be positive, such as new habitat created by storm deposits. The U.S. Geological Survey (USGS) is meeting the need for scientific understanding of how our coasts respond to different hazards with continued assessments of current and future changes along U.S. coastlines. Through the National Assessment of Coastal Change Hazards (NACCH), the USGS carries out the unique task of quantifying coastal change hazards along open-ocean coasts in the United States and its territories. Residents of coastal communities, emergency managers, and other stakeholders can use science-based data, tools, models, and other products to improve planning and enhance resilience.

Sulfur Upwelling off the African Coast  

NASA Technical Reports Server (NTRS)

Though these aquamarine clouds in the waters off the coast of northern Namibia may look like algae blooms, they are in fact clouds of sulfur produced by anaerobic bacteria on the ocean's floor. This image of the sulfur-filled water was taken on April 24, 2002, by the Sea-viewing Wide Field-of-View Sensor (SeaWiFS), flying aboard the Orbview-2 satellite. The anaerobic bacteria (bacteria that can live without oxygen) feed upon algae carcasses that exist in abundance on the ocean's floor off of Namibia. As the bacteria ingest the algae husks, they produce hydrogen sulfide, which slowly builds up in the sea-floor sediments. Eventually, the hydrogen sulfide reaches the point where the sediment can no longer contain it, and it bubbles forth. When this poisonous chemical reaches the surface, it combines with the oxygen in the upper layers of the ocean to create clouds of pure sulfur. The sulfur causes the Namibian coast to smell like rotten eggs, and the hydrogen sulfide will often kill fish and drive lobsters away. For more information, read: A Bloom By Any Other Name A high-resolution (250 meters per pixel) image earlier on the 24th taken from the Moderate-Resolution Imaging Spectroradiometer (MODIS) shows additional detail in the plumes.

Origin of barrier islands on sandy coasts  

SciTech Connect

Many barrier islands on the coasts of the Gulf of Mexico contain one or more nuclei; island growth has taken place more or less seaward from these nuclei, which are the oldest parts of the islands. The nuclei were, at one time, separate islands; the oldest beach ridges wrap around them on two or three sides, showing that they were not remnants of spits or earlier larger features. The nuclei grew larger with time because of a local equilibrium of abundance of sand, rather than a regime of erosion. The younger growth areas are commonly marked by sequences, or sets, of beach ridges; such features are not visible in the nuclei. The question of the origin of many barrier islands on sandy coasts must be closely related to the question of the origin of the nuclei. But the nuclei appear to have no distinguishing marks that in themselves might help explain their origin. Johnson Shoal (Lee County, on the lower west coast of the Florida peninsula) may provide some insight into the origin of nuclei. It appeared for the first time, more recently than 1853, in water 2-6 m deep, and has been migrating landward (eastward) ever since. Seven maps and charts from various dates and many sets of black-and-white aerial photographs have been used to produce a history of shoal migration. By December 1988, welding of the remnants of the shoal onto the shore of Cayo Costa island was already under way. The migrating shoal contained more than 10 million m{sup 3} of sand (13 million yd{sup 3}), with a mass of 10 trillion kg. Known nuclei on other islands are commonly about this size, or smaller. The moving shoal did not develop from dredge spoil (there has been no dredging of this magnitude in the area), a spit, a drowned dune, or a fault. It must have been a natural nontectonic event: emergence of a shoal since 1853 without notable changes in sea level or wave climate. Perhaps such events, common a few thousand years ago, account for barrier island nuclei.

Main Coast Winds - Final Scientific Report  

SciTech Connect

The Maine Coast Wind Project was developed to investigate the cost-effectiveness of small, distributed wind systems on coastal sites in Maine. The restructuring of Maine's electric grid to support net metering allowed for the installation of small wind installations across the state (up to 100kW). The study performed adds insight to the difficulties of developing cost-effective distributed systems in coastal environments. The technical hurdles encountered with the chosen wind turbine, combined with the lower than expected wind speeds, did not provide a cost-effective return to make a distributed wind program economically feasible. While the turbine was accepted within the community, the low availability has been a negative.

US Coast Guard differential GPS network  

SciTech Connect

In order to aid navigation and to prevent disasters such as oil spills, collisions, and wrecks of vessels and aircraft, the US Coast Guard is charged with establishing, maintaining, and operating electronic aids to navigation. In a technological advance developed and operated by the Department of Defense, the global positioning system (GPS) provides all-weather global coverage, 24 hours/day at unprecedented accuracies. GPS provides standard positioning service (SPS) and precise positioning service (PPS). By applying differential techniques to GPS, navigational accuracies of better than 10 meters can be achieved. For the first time, an all-weather system is possible to meet all the marine navigator's needs including harbor and harbor approach navigation. This should revolutionize navigation safety and efficiency, surveying operations, search and rescue operations, and underwater mine disposal efficiency and safety.

Geothermal structure of Australia's east coast basins  

NASA Astrophysics Data System (ADS)

The east coast sedimentary basins of Australia formed on an active margin of eastern Gondwana, and constitute an important hydrocarbon resource. The 1600km long Sydney-Gunnedah-Bowen Basin (SGBB) is largest east coast basin system, with thick Permian to Jurassic sedimentary successions overlying Palaeozoic basement rocks. The SGBB has been the focus of renewed geothermal exploration interest, however, the thermal state and geothermal potential of the system is largely unconstrained. Geothermal exploration programs require an accurate estimate of subsurface temperature information, in addition to favourable geology, to make informed decisions on potential targe developments. Primarily temperature information comes from downhole measurements, generally non-equilibrated, which are traditionally extrapolated to depth, however such extrapolation does not take into account variations in geological structure or thermal conductivity. Here we import deep 3D geological models into finite element conduction simulations, using the code Underworld, to calculate the deep thermal structure of the basin system. Underworld allows us to incorporate complex, detailed geological architecture models, incorporating different material properties for different layers, with variable temperature and depth-dependent properties. We adopt a fixed top boundary temperature on a variable topographic surface, and vary the bottom surface boundary condition, to converge of models which satisfy equilibrated downhole temperature measurement constraints. We find coal plays an important role in insulating sedimentary basins. Heat refracts around the coal interval and produces elevated temperatures beneath thick sediments, especially where thick coal intervals are present. This workflow has been formalized into an Underworld geothermal model library, enabling model centric computational workflows. Using the imported model architecture from the geology, data can be continuously updated and added to the system and models quickly re-run to take advantage of the most up to date information. The thermal models we’ve produced for the SGBB are an efficient regional assessment of the geothermal resource potential in this basin system.

Regional beach/cliff system dynamics along the california coast  

USGS Publications Warehouse

The coast of California is comprised of both sandy shorelines and cliffed coastline, and in many areas these features spatially coincide. In order to better understand the regional trends of change along the California coast, the U.S. Geological Survey is quantifying both sandy shoreline change and coastal cliff retreat for the state. The resulting database was used to examine the dynamics of the beach/cliff system. We found inconsistent evidence of a relationship between rates of cliff retreat and shoreline change on the spatial scale of 100-km cells. However, when the data are correlated within individual regions, a strong relationship exists between the geomorphology of the coast and the behavior of the beach/cliff system. Areas of high-relief coast show negative correlations, indicating that higher rates of cliff retreat correlate with lower rates of shoreline erosion. In contrast, low- to moderate-relief coasts show strong positive correlations.

Statistics of rocky coast erosion and percolation theory  

NASA Astrophysics Data System (ADS)

The dynamics of rocky coasts is an erratic phenomenon featuring numerous small erosion events, but sometimes large dramatic collapses. In this sense, its study should not limit or rely on average erosion rates. Recent studies, based on historical as well as recent data, have indicated that the frequency of magnitude of erosion events display long tail distribution, similar to what observed in landslide. In other words the time evolution of a coast morphology does not enter the classical category of Gaussian process, but rather that of critical systems in physics. We recently proposed a minimal dynamical model of rocky coast erosion which is able to reproduce the diversity of rocky coast morphologies and their dynamics. This model is based on a single, simple ingredient, the retroaction of the coast morphology on the erosive power of the sea. It follows from the idea that erosion can spontaneously create irregular seashores, but, in turn, the geometrical irregularity of the coast participates to the damping of sea-waves, decreasing the average wave amplitude and erosive power. The resulting mutual self-stabilization dynamics of the sea erosion power and coastal irregular morphology leads spontaneously the system to a critical dynamics. Our results indicate then that rocky coast erosion and the statistical theory of percolation are closely related. In this framework, the sometimes fractal geometry of coastlines can be recovered and understood in terms of fractal dimension of the external perimeter of a percolation cluster. From a more practical point of view, the analogy with percolation interfaces means that the coast constitutes a strong, but possibly fragile, barrier to sea erosion, emerging from a self-organised selection process. Accordingly, the effect of a slow weathering degradation of the rocks mechanical properties, as well as other perturbations from natural or human cause, can trigger random and large erosion events difficult to predict and control. To the extent that these ideas apply, natural coasts should be "preserved" and managed with care.

Studying changes of ice coasts in the European Arctic  

NASA Astrophysics Data System (ADS)

The present extent of European ice coasts, their spatial changes in the past 50 years and the velocities of ice flow in marginal parts of tidewater glaciers were determined and mapped at a regional scale using space-borne image data, both optical and radar. The methods of satellite photogrammetry and radar interferometry provided efficient solutions to the integral estimation of ice-coast dynamics in the Franz Josef Land, Novaya Zemlya and Svalbard archipelagos. Studies revealed significant degradation of the ice coasts (-7.7% by length) compared to the situation represented in the available maps. The results obtained in the laboratory were verified during several field campaigns.

Post Fukushima tsunami simulations for Malaysian coasts  

NASA Astrophysics Data System (ADS)

The recent recurrences of mega tsunamis in the Asian region have rekindled concern regarding potential tsunamis that could inflict severe damage to affected coastal facilities and communities. The 11 March 2011 Fukushima tsunami that crippled nuclear power plants in Northern Japan has further raised the level of caution. The recent discovery of petroleum reserves in the coastal water surrounding Malaysia further ignites the concern regarding tsunami hazards to petroleum facilities located along affected coasts. Working in a group, federal government agencies seek to understand the dynamics of tsunami and their impacts under the coordination of the Malaysian National Centre for Tsunami Research, Malaysian Meteorological Department. Knowledge regarding the generation, propagation and runup of tsunami would provide the scientific basis to address safety issues. An in-house tsunami simulation models known as TUNA has been developed by the authors to assess tsunami hazards along affected beaches so that mitigation measures could be put in place. Capacity building on tsunami simulation plays a critical role in the development of tsunami resilience. This paper aims to first provide a simple introduction to tsunami simulation towards the achievement of tsunami simulation capacity building. The paper will also present several scenarios of tsunami dangers along affected Malaysia coastal regions via TUNA simulations to highlight tsunami threats. The choice of tsunami generation parameters reflects the concern following the Fukushima tsunami.

Sequestration Options for the West Coast States  

SciTech Connect

The West Coast Regional Carbon Sequestration Partnership (WESTCARB) is one of seven partnerships that have been established by the U.S. Department of Energy (DOE) to evaluate carbon capture and sequestration (CCS) technologies best suited for different regions of the country. The West Coast Region comprises Arizona, California, Nevada, Oregon, Washington, Alaska, and British Columbia. Led by the California Energy Commission, WESTCARB is a consortium of about 70 organizations, including state natural resource and environmental protection agencies; national laboratories and universities; private companies working on carbon dioxide (CO{sub 2}) capture, transportation, and storage technologies; utilities; oil and gas companies; nonprofit organizations; and policy/governance coordinating organizations. Both terrestrial and geologic sequestration options were evaluated in the Region during the 18-month Phase I project. A centralized Geographic Information System (GIS) database of stationary source, geologic and terrestrial sink data was developed. The GIS layer of source locations was attributed with CO{sub 2} emissions and other data and a spreadsheet was developed to estimate capture costs for the sources in the region. Phase I characterization of regional geological sinks shows that geologic storage opportunities exist in the WESTCARB region in each of the major technology areas: saline formations, oil and gas reservoirs, and coal beds. California offers outstanding sequestration opportunities because of its large capacity and the potential of value-added benefits from enhanced oil recovery (EOR) and enhanced gas recovery. The estimate for storage capacity of saline formations in the ten largest basins in California ranges from about 150 to about 500 Gt of CO{sub 2}, the potential CO{sub 2}-EOR storage was estimated to be 3.4 Gt, and the cumulative production from gas reservoirs suggests a CO{sub 2} storage capacity of 1.7 Gt. A GIS-based method for source-sink matching was implemented and preliminary marginal cost curves developed, which showed that 20, 40, or 80 Mega tonnes (Mt) of CO{sub 2} per year could be sequestered in California at a cost of $31/tonne (t), $35/t, or $50/t, respectively. Phase I also addressed key issues affecting deployment of CCS technologies, including storage-site monitoring, injection regulations, and health and environmental risks. A framework for screening and ranking candidate sites for geologic CO{sub 2} storage on the basis of HSE risk was developed. A webbased, state-by-state compilation of current regulations for injection wells, and permits/contracts for land use changes, was developed, and modeling studies were carried out to assess the application of a number of different geophysical techniques for monitoring geologic sequestration. Public outreach activities resulted in heightened awareness of sequestration among state, community and industry leaders in the Region. Assessment of the changes in carbon stocks in agricultural lands showed that Washington, Oregon and Arizona were CO{sub 2} sources for the period from 1987 to 1997. Over the same period, forest carbon stocks decreased in Washington, but increased in Oregon and Arizona. Results of the terrestrial supply curve analyses showed that afforestation of rangelands and crop lands offer major sequestration opportunities; at a price of $20 per t CO{sub 2}, more than 1,233 MMT could be sequestered over 40-years in Washington and more than 1,813 MMT could be sequestered in Oregon.

Oceanic Loading Eect near the European Coast  

NASA Astrophysics Data System (ADS)

The dissipation, anisotropy, and rotation constraints of the total oceanic gravimetric effect are analysed. The dependence of the results on the selected P- and S-velocity model (i.e., on the structure of the crust and upper mantle of the Earth) is considered. For calculating the effect of oceanic loading, we apply the method of Legendre polynomial expansion of tidal heights. The CSR3 model data are expanded up to the 720th order. The results yielded by this method closely agree with those calculated from the Green's functions by the LOAD07 program of the ETERNA software. Remarkable advantage of our program over other approaches is that it provides high-speed processing and does not require introducing the near-field formalism. Application of the pre-computed expansions reduces the time of calculations by two orders of magnitude, compared to LOAD07. This is particularly important when analyzing the geographical distributions of the loading effect predicted by different models. Taking dissipation into account improves the total gravimetric effect calculated for the M2 wave near the coast of Europe by 0.1-0.2 mcGal in amplitude and by a few hundredths of degree in phase. Transition from the PREM model to the IASP91 model which is better suitable for Europe changes the model predictions by 0.1-0.4 mcGal in amplitude and by 0.1 to 5-7 degrees in phase. Thus, allowance for dissipation together with the use of the refined data on the crustal and upper-mantle structure of the Earth may contribute, at places, over 0.5 mcGal to the amplitude and a few degrees to the phase of the total oceanic gravimetric effect. In this relation, particular attention should be paid to the regions about the Land's End cape (Cape Cornwall) and Cape Saint Mathieu.

Mysterious Black Water off Florida's Gulf Coast  

NASA Technical Reports Server (NTRS)

In mid-December last year, a mysterious black water overtook the normally bluish green waters of Florida Bay. Over the course of the winter, the extent of the water grew to encompass an area as big as Lake Okeechobee, Florida, before subsiding over the last few weeks. These images taken by the Sea-viewing Wide Field-of-View Sensor (SeaWiFS), flying aboard the Orbview-2 satellite, show the progression of the black water over the last three months. The affected water sits along the southeastern coast of Florida about fifty miles north of the Florida Keys. As of now, scientists do not know why the water appears black in satellite and aerial images or whether the water is harming the wildlife. They speculate that it could be due to an exotic algae bloom, an underwater fountain pushing up sediments from the ocean floor, or possibly chemical and sediment run-off from the nearby Shark River. Researchers at the Florida Marine Research Institute in St. Petersburg and the Mote Marine Research Institute in Sarasota are running tests to determine the chemical make-up of the water. No big fish kills have been reported in the area. But fishermen say the catch has been low this winter. In addition, the black water sits just north of the Florida Keys National Marine Sanctuary, which is home to one of the largest coral reef habitats in the United States. Toxic run-off from the Florida coastline and motor boats in the area have already destroyed many of Florida's reefs. Scientists are concerned that if the extent of the black water grows again, it could endanger these reefs. Information provided by the Naples Daily News.

Rock coasts and seabird breeding sites : a common optimization  

NASA Astrophysics Data System (ADS)

The North-West coasts of Europe support a lot of part of Northern hemisphere breeding seabirds. In that context, Scotland has a preponderant place and Brittany has southernmost limit of these species areas, for most of them. Outside the breeding season these species live mainly on the open sea and when they do visit the land to breed, they nest on a specific sites : almost all the time they breed on the rock coasts, often on seacliffs. This specific habitat are defines by geomorphological characteristics which offer special forms of the coast. The forms of rock coasts are originally and different because of several proprieties of geology, of lithology, of structures. Breeding seabird, occupying these sites, reveals, in a new light, the richness of these forms and the originals geographic location of the coastline : seabirds prefer nest in exposed coastline like rock caps, rocky points or islands. Seabirds and rock coasts are research topics in environmental geography since several years. However, these combination studies is a new approach in this field and enlargement in the heritage field allows supplement scientific approach. For example, it show that in most important touristic sites, environmental protection measures focused on landscape, habitat or bird, but much more rarely on rock coasts for these intrinsic values. Indeed, in Brittany or in Scotland, seabirds are often stars species in lot of coastal nature reserves, where they're considered like greater ecological heritage. We could see it in touristic promotion field : bird is everywhere, cliff is mostly kept in the dark, as well in leaflets as in speech visitor's guides - without, for example, as a part of this landscape. In all cases, combination of these two heritages is extremely rare. Yet, this current research illustrates the interest and the issue of development of this comparative approach seabirds / rock coasts for optimization of nature tourism and geotourism.

COAST: Cascadia Open-Access Seismic Transects  

NASA Astrophysics Data System (ADS)

The Cascadia margin is the site of active subduction, where the Juan de Fuca plate subducts under the North American plate at a rate of ~35 mm/yr. This system is of great scientific and societal interest, as it is capable of very large (Mw~9) earthquakes, creates volcanic hazards in the Cascades, and hosts periodic episodic tremor and slip (ETS) episodes. Despite evidence that the system has generated large megathrust earthquakes, limited seismicity creates large uncertainties in the position, structure, and physical state of the plate boundary. The COAST (Cascadia Open-Access Seismic Transects) project conducted an open-access, open-participation 2D seismic survey of the Cascadia subduction margin off Grays Harbor, WA, that will provide benchmark seismic images to address key scientific issues regarding the location, physical state, fluid budget, and associated methane systems of the subducting plate boundary and overlying crust. We collected seismic reflection, multibeam bathymetric, sidescan sonar, gravity, and magnetic data on the Cascadia subduction margin from the R/V Langseth in July 2012 in a high-priority GeoPRISMS corridor off Grays Harbor, Washington. The cruise was open-participation, with an organized shipboard education and training program, and the data are open-access, with immediate, full release to the community of all geophysical data. Project goals include (1) determining the location of the offshore plate boundary, (2) constraining sediment subduction and plate boundary roughness, (3) estimating pore fluid pathways, (4) determining controls on methane distribution, and (5) imaging compressional and extensional structures that may pose geohazards on the Cascadia margin. Initial observations include the following: (1) The Pleistocene accretionary wedge is well imaged and shows landward-vergent thrust faulting throughout our survey area. An outboard series of ramp-and-thrust structures gives way to a region characterized by folds that separate "oases" of undeformed sediment. (2) The oceanic basement reflection is strong and clear outboard of the deformation front but becomes much weaker beneath the Pleistocene wedge. At this stage of processing it is not clear whether this reflects inaccurate processing, loss of energy by scattering off a complex surface, or (more intriguingly) a physical change in the plate boundary structure. (3) Where it is imaged beneath the margin, the top of oceanic crust appears nearly flat or gently dipping beneath the Pleistocene wedge, then bends into a steeper inclination beneath the Miocene wedge. (4) A widespread methane hydrate system, indicated by bottom-simulating reflections, exists in the outer wedge and upper slope of our area. The BSR's are strongest in tilted sediments, suggesting that fluid flow along bedding planes contributes to the hydrate system.

[figure removed for brevity, see original site] [figure removed for brevity, see original site] Figure 1Figure 2

The topography of the Gulf Coast states is well shown in this color-coded shaded relief map generated with data from the Shuttle Radar Topography Mission. The image on the top (see Figure 1) is a standard view showing southern Louisiana, Mississippi, Alabama and the panhandle of Florida. Green colors indicate low elevations, rising through yellow and tan, to white at the highest elevations.

For the view on the bottom (see Figure 2), elevations below 10 meters (33 feet) above sea level have been colored light blue. These low coastal elevations are especially vulnerable to flooding associated with storm surges. Planners can use data like these to predict which areas are in the most danger and help develop mitigation plans in the event of particular flood events.

Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Geospatial-Intelligence Agency (NGA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate, Washington, D.C.

Chesapeake Bay Crater, Virginia: Confirmation of Impact Origin  

NASA Astrophysics Data System (ADS)

Poag et al. [1] identified a late Eocene boulder bed in drill cores from southeast Virginia, and interpreted it as an impact-generated tsunami deposit. Seismic studies and other geophysical evidence indicated the existence of a possible impact structure centered at Chesapeake Bay (37 degrees x 15' N and 76 degrees x 04' W), which may be 85-90 km in diameter [2]. Four drill cores have penetrated into the breccia, although none is available from the center of the structure, or reaches basement. A central peak-ring of crystalline rocks with about 25 km diameter is surrounded by a 30 km-wide annular trough and terrace terrane. The trough is filled with polymictic breccia composed mainly of autochthonous sedimentary clasts in a sandy matrix with some angular clasts of granitic and metasedimentary basement rocks [2]. The Chesapeake Bay crater is of special interest, because it is close to the region identified as the possible source region for the North American tektites, is of about the expected size, and has an age identical to that of the tektites [3]. While the source craters for the Central European and Ivory Coast tektite strewn fields are known, the source crater of the North American tektites has remained elusive. A variety of locations were suggested, including Popigai (Siberia), Wanapitei (Canada), Mistastin (Canada), and Bee Bluff (Texas), but all were later discounted. The distribution of the tektites and microtektites in the strewn field suggests that the North American tektite source crater is likely to be located at or near the eastern coast of the North American continent, maybe underwater [4,5]. The location of the Chesapeake Bay structure is in agreement with the area suggested before [4,5]. We have started a petrological and geochemical study of target rocks and breccias from the Chesapeake Bay structure. We analyzed the major and trace element composition of 17 mainly sedimentary samples, for comparison with North American tektite values. 14 of these samples, from 368 to 423 m depth, are from the Exmore core, which was drilled at the outer limit of the crater. The samples consist mainly of various siltstones, sandstones, with some shale and graywacke. The silica content of the samples studied ranged between 32 and 73 wt%. Some samples are very rich in carbonates. Recalculating the high-silica samples (some sandstones) to a carbonate- and water-free composition yields results that are similar to, but not identical with, those of the more silica-poor North American tektites. Petrographical thin section studies were done on about 40 sediment, metasediment, and crystalline rock samples from the Exmore and Kiptopeke cores. The samples included some crystalline rock clasts and millimeter-sized loose particulates. We found abundant evidence of shock metamorphic effects in numerous samples from the Exmore core, at depths from 372 to 414 m. Shock metamorphic effects were recorded as planar deformation features (PDFs) in quartz, K-feldspar, and plagioclase. In quartz and K- feldspar, up to three intersecting sets of PDFs with characteristic crystallographic orientations were found. A histogram of PDF orientations showed predominantly {10bar13} (omega), {10bar12} (pi), and {22bar41} orientations, with only very few unindexed planes. The PDF orientations suggest a peak pressure >16 GPa. Shock effects were recognized only in crystalline rock fragments or clasts, but not in sedimentary material. In addition, numerous clasts show evidence of partial or complete melting and annealing, and some small impact melt rock inclusions (probably part of impact melt breccias) were recognized. Our findings provide confirming evidence that the Chesapeake Bay structure is indeed an impact structure. Acknowledgments: Supported by FWF Project P-8794-GEO. References: [1] Poag C. W. et al.

Effects of sea level rise on rugged coasts  

SciTech Connect

Rugged coasts are usually rock framed, with more or less discontinuous unconsolidated sediment supply. Evolution of rugged coasts with respect to rising sea level is locally variable, involving rapid changes in facies over short distances and times. Glaciated and tectonic coasts are common examples. Three aspects of coastal evolution dominate rugged coasts during rising sea level: (1) drowning of resistant rocky shores, (2) bluff erosion in sediments or cliff erosion in less resistant rocks, involving marine abrasion as well as terrestrial processes and control by rock structures, and (3) larger scale structural control creating indentations and salients. The third aspect results in embayed coasts that may evolve as estuarine, fjord, or barrier-backbarrier systems. Of overriding concern for stratigraphic interpretation are paleogeography and sediment sources. The Maine coast and nearshore are classic examples of drowned shoreline, and record the effects of glaciation and rapid relative sea level changes over the past 14,000 yr. Offshore at {minus}60 m is a lowstand shoreline (approximately 10,000 yr B.P.), which ranges from cliff to barrier split( ). The inner shelf has evolved through drowning of shelf valleys and peninsulas, bluff erosion and formation of local transgressive barrier-backbarrier systems. Often short-term steady state equilibrium is established until a threshold is reached followed by rapid reorganization at a new location. This occurs in barrier systems, by overtopping of sills in estuaries, and in variable bluff and cliff erosion sites. Preservation potential is high only in valley axes and at sea level stillstand positions.

Evaluation of tsunami vulnerability along northeast coast of India  

NASA Astrophysics Data System (ADS)

The Sumatra tsunami of 26 December 2004 with a moment magnitude of 9.3 Mw caused colossal damage to the south-southeastern Indian coast and Andaman-Nicobar group of Islands. However, the northeastern coastline bordering the northwestern Bay of Bengal remained unaffected although a tidal station located in the region recorded the highest water level (~2.5 m) for the entire east coast of India on the eventful day. As a part of hazard mitigation and planning for the northeastern coast, four major settlements, viz., Gopalpur, Puri, Paradip and Digha were evaluated for tsunami vulnerability. Inundation and run-up scenarios were generated for Bay of Bengal earthquake sources such as Arakan-1762, Car Nicobar-1881, North Andaman-1941 and Sumatra 2004 using TUNAMI N2 model. The paper describes computed run-up heights and landward inundation for 20-25 km coastal stretch with different geomorphologies and topographical characteristics. Simulation results indicate that the model is able to generate a comparable run-up of 2-4.5 m for 2004 Sumatra event for Paradip region while at other locations of the coastline, it was largely unnoticed as the inundation remained within the beach limit; however water entered inland mainly through the waterways and inundated low-lying areas. It is concluded that northeast coast of India is relatively safe from the tsunami originating in Bay of Bengal region.

Shoreline change analysis of Vedaranyam coast, Tamil Nadu, India.  

PubMed

The coastal zone is one of the nation's greatest environmental and economic assets. The present research aims at studying the shoreline changes along Vedaranyam coast using conventional and modern techniques including field sampling, remote sensing, and geographical information system (GIS). The study area was divided into three zones. Dynamic Land/Sea polygon analysis was performed to obtain the shore line changes at different time periods between 1930 and 2005. From the multidate shoreline maps, the rate of shoreline change was computed using linear regression rate and end point rate. Further, the shoreline was classified into eroding, accreting, and stable regions through GIS analysis. The eroding, accreting, and stable coastal stretch along Vedaranyam is observed as 18 %, 80.5 %, and 1.5 %, respectively. Net shoreline movement is seaward, i.e., the coast is progressive with an average rate of 5 m/year. A maximum shoreline displacement of 1.3 km towards the sea is observed near Point Calimere. During the Asian Tsunami 2004, the eastern part of the study area showed high erosion. Sediment transport paths derived from the grain size analysis of beach sediments collected during different seasons help to identify the major sediment source and sinks. Point Calimere acts as the major sink for sediments whereas Agastiyampalli and Kodiakkarai are found to be the major sources for the sediment supply along the Vedaranyam coast. Shoreline change study from field and satellite data using GIS analysis confirms that Vedaranyam coast is accreting in nature. PMID:23054290

Regional seismotectonic model for the southern Coast Ranges  

SciTech Connect

On the basis of seismicity in the southern Coast Ranges for the 11 years before the May 2 earthquake and on focal mechanisms of selected moderate recent earthquakes in the region, the authors propose a model for the generation of reverse- and thrust-fault earthquakes, such as the May 2 earthquake, along both the east and west flanks of the Coast Ranges. These earthquakes appear to result from a component of apparent convergent displacement across the San Andreas transform system in the southern Coast Ranges. Earthquakes with reverse and thrust focal mechanisms occur in regions with a distinctive pattern of seismicity characterized by detached clusters of epicenters. These regions lie along the flanks of the southern Coast Ranges and are separated from the San Andreas fault by other regions of relative quiescence. In this model, the reverse- and thrust-fault earthquakes occur where detachment zones within a ductile lower crust beneath the center of the transform system pass upward into the brittle upper crust along its margins. Convergence across the transform system, together with regions of unusually strong materials in the brittle upper crust flanking the San Andreas fault southeast of Cholame, may also play an important role in producing great earthquakes in that region.

Relative importance of estuarine flatfish nurseries along the Portuguese coast  

NASA Astrophysics Data System (ADS)

The relative importance of nursery areas and their relationships with several environmental variables were evaluated in nine estuarine systems along the Portuguese coast based on trawl surveys. Historical data were used to outline changes and trends in the nursery function of some of these estuaries over the past decades. The dominant flatfish species in Portuguese estuaries were Platichthys flesus (Linnaeus, 1758), Solea solea (Linnaeus, 1758), Solea senegalensis Kaup, 1858 and Monochirus hispidus Rafinesque, 1814, but their occurrence differed among the estuaries. P. flesus only occurred in estuaries north of the Tejo estuary (39°N), S. solea was quite rare along the southern Portuguese coast (south of 37°30'N), S. senegalensis occurred in estuaries throughout the coast, but its abundance varied considerably, and the occurrence of M. hispidus was limited to the Sado estuary and Ria Formosa. A Correspondence Analysis was performed to evaluate the relationships between flatfish species abundance and geomorphologic and hydrologic characteristics of estuaries (latitude, freshwater flow, estuarine area, intertidal area, mean depth and residence time). Abiotic characteristics (depth, temperature, salinity, sediment type) of nursery grounds of each flatfish species were also evaluated. Results showed that some estuaries along the Portuguese coast have nursery grounds used by several flatfish species (e.g. Ria de Aveiro, Sado estuary), while in other systems a segregation was noticed, with juveniles of different species occurring in distinct estuarine areas (e.g. Minho and Mondego estuaries). This emphasizes the relevance of niche overlap, but the potential for competition may be considerably minimized by differences in resource use patterns and by an extremely high abundance of resources. Peak densities of flatfishes recorded in nurseries areas along the Portuguese coast were within the range of values reported for other geographical areas. Inter-annual abundance variability of all the species in the Tejo and Sado estuaries was extremely high, with a drastic decrease in P. flesus in the Tejo estuary, probably related to higher water temperature in recent years due to global climate change.

Human impact on dynamics of Barents and Kara Seas Coasts  

NASA Astrophysics Data System (ADS)

The coasts of Barents and Kara Seas which are composed of unconsolidated deposits have poor erosion resistance qualities. In natural conditions such coasts may retreat with a rate of 1 to 2 m a year. Under the influence of human activities this rate can double and even triple. Over the last twenty years the human impact on the natural coastal geosystems has noticeably increased due to the latest oil and gas developments on the sea shelf and coasts of the Russian North. A range of facilities - oil custody terminals for drilling and production platforms, submerged pipelines, ports and other industrial features and residential infrastructure - are currently being operated in the coastal and shelf zones. In most of the cases no morphodynamic or lithodynamic features of the coastal zone had been taken into account during the construction or operation of these facilities. This results in a disturbance of the sediment transport in the coastal zone, which triggers active erosion of both the shore itself and the coastal slope beneath. The operated facilities themselves are then threatened as their destruction is possible and often no new facilities can be constructed in the disturbed area. The operating companies have to bear forced nonmanufacturing expenses to protect or move their facilities of oil and gas industry to new areas. We may cite here three instances for Barents and Kara Seas where human impact has already brought in negative effects. One of the examples is Varandey Coast of the Barents Sea. From 1979 to 2012 a deliberate destruction of the dune chain of the barrier beach by vehicle traffic and a removal of the beach material for construction needs led to a quick intensification of the coastal retreat here. And now, storm surges without hindrance penetrate inland for several kilometers. Let's move further east to the Kara Sea: on to Kharasavey Coast to the Yamal Peninsula. A large-scale extraction of sediments from the coastal slope has resulted in a depletion of the material on the beaches and triggered violent thermoabrasion of the coast in 1982-1985 and 2006-2008. Third example of the negative impacts of human activities takes place at the sites of entrance underwater gas to the Coast of Baydarata Bay Kara Sea. Here also designers and builders are not taken into account negative experience of management and sediment removal, as it was at Varandey and Harasavey industrial areas. Construction of the pipeline, accompanied by numerous technogenic effects and removal of sediment from the beach and tide-flat, in period from 2007 to 2012 led to multiple increases in the rate of coastal erosion. A truly responsible decision making towards the strategy of developing the northern coasts of Russia and constructing new facilities is to be based upon an integrated knowledge of the ongoing environmental processes, in particular coastal dynamics. The ignoring of this issue may cause irreversible damage to both the coastal geosystems and the facilities themselves, which, once they are destructed, may drag in enormous environmental implications.

Geologist argues for renewed, deeper look at US Gulf Coast  

SciTech Connect

Over 10 bbo (billion barrels of oil) and about 130 Tcf of gas have been reported as proved reserves discovered in the offshore U.S. continental shelf (OCS or outer continental shelf) along the northern Gulf Coast. Of these reserves, only 2.5 bbo and 36,146 Bcf of gas remain, which seem small in comparison to a U.S. consumption rate of over 5 bbo/yr. Reserves, new additions and production levels in the Gulf Coast region have fallen for the last decade and more. Rig and crew boat counts are down, employment is down, and it is difficult for most to remain optimistic. This paper reports that there is good reason for optimism---A major new exploration play for oil and gas exists on the Texas/Louisiana shelf. Modern geological, geophysical (mainly seismic) and geochemical data, when combined, offer a sound base for a major renewed exploration campaign.

Paleogeography of Cretaceous ammonoids of the Pacific coast of Russia  

NASA Astrophysics Data System (ADS)

This work presents the results of a study of the biogeographical distribution of Late Albian-Maastrichtian ammonites, found in sequences of the Pacific coast of Russia. The taxa typical of the Pacific Realm were identified, and their distribution traced beyond the borders of this region. In addition, species-migrants, distributed within the studied area were established. As a results of our works, a high level of endemism of ammonite fauna of the East of Russia was noted (75-88% of endemic species, on average). The bipolarity, previously established in the distribution of ammonoids within the Pacific Paleobiogeographical Realm, as well as their high regional provincialism, was confirmed. The following division of the studied area into faunal ammonite provinces in the Late Cretaceous was proposed: Arctic Province; Boreal-Pacific Province, including northeastern Russia (Chukotka Peninsula, the Koryak Upland, Penzhyna Gulf) and the boreal coast of North America (Alaska Peninsula, Arctic Canada and British Columbia); Northwest Pacific Province, including the Primorye Territory, Sakhalin and Shikotan Islands, the Japanese Islands; Northeast Province of the Pacific (the western coast of the United States and Mexico); Southwest Pacific (Australia, New Zealand, Oceania) and Southeast (the western coast of South America and Antarctica, Seymour and James Ross Islands) Provinces. This division is confirmed by data on inoceramid species. In addition, levels of global transgressions and general sea level rise, associated with the appearances of most of widespread marine taxa in the Pacific shelf seas, are established. These include Late Albian, Cenomanian-Turonian boundary, Late Coniacian, Late Campanian, Early-Late Maastrichtian boundary. Moreover, migration of ammonites occurred due to the Tethys Ocean extension and followed the northern sea straits in the Arctic Ocean and within the Pacific Realm, depending on warm currents. Both the counter and one-way migrations were established.

Meteorological tsunamis along the East Coast of the United States  

NASA Astrophysics Data System (ADS)

Tsunami-like intense sea level oscillations are common along the East Coast of the United States. They are generated by various types of atmospheric disturbances, including hurricanes, frontal passages, tornados, trains of atmospheric gravity waves, pressure jumps, squalls, and gales, that each set up a local, time-limited barotropic response in the affected body of water. These meteorologically induced waves have the same temporal and spatial scales as their seismically generated counterparts and inflict comparable destructions. Observed around the globe, these devastating waves are known locally as "abiki" in Nagaski Bay (Japan), "rissaga" in Spain, "š?iga" along the Croation Coast bordering the Adriatic Sea, "milghuba" in Malta, and "marrobbio" in Italy. Collectively, they may be considered as "meteorological tsunamis" or "meteotsunamis." The updated NOAA tide gauge network with 1 min sampling enabled us to examine resonant amplifications of specific events observed in 2007-2012 and physical properties of meteotsunamis impacting the United States East Coast in general. Of particular interest and focus was the "derecho" event of June 29 - July 2, 2012.

Development of mining methods in Gulf Coast lignites  

SciTech Connect

Costs to open new mines in the Gulf Coast region will be high and lead times long (average seven years). The capital investment for overburden removal equipment, the size under consideration for the region, is projected to be a third to one half the total mine project investment. Therefore, the analysis of the most efficient system or combination of systems must be evaluated in these future Gulf Coast lignite mines. Figure 4 shows the projected direct stripping cost per ton of a typical Gulf Coast lignite mine with an annual production of 4.5 Mt (5 million st). For a 63 m (200 ft) deep pit, the dragline method seems to be the cheapest approach. Stripping costs are higher for a bucket wheel excavator system, but the bucket wheel excavator system is less expensive than the truck-shovel or scraper system. Thus, in deeper lignite mines, as much overburden as possible should be allocated to the dragline--based on operational limitations, prospective geological and geotechnical conditions, and the draglines' projected rehandle quantities. To minimize cost, remove overburden at greater depths, and provide successful reclamation, a combination mining method may be the optimum materials handling approach.

Littoral processes: US Coast Guard Station, Fort Point, San Francisco  

SciTech Connect

The US Coast Guard Station, Fort Point is located three-quarters of a nautical mile southeast of the Golden Gate Strait, the entrance to San Francisco Bay. The existing storm wave conditions at Fort Point Station pier make it extremely dangerous for the SAR crews to get on and off the Motor Life Boats at times requiring the vessels to be moored at the San Francisco Yacht Harbor about 1.5 miles east of the Fort Point Station. To mitigate these harsh working conditions the US Coast Guard is considering the feasibility of constructing suitable all-weather moorings for the three Motor Life Boats at the Fort Point Station to enable unimpeded SAR operations, to provide safe working conditions for Coast Guard small boat crews, and to improve small boat maintenance conditions at Fort Point Station. The purpose of this report is to identify, analyze and evaluate physical environmental factors that could affect all-weather moorings siting, configuration and entrance location, as well as potential post construction alterations to littoral conditions and processes. This report includes a description of the site, description of pertinent littoral processes, evaluation of how these processes could affect construction of all-weather moorings, and discussion of design considerations, as well as mitigation measures to minimize potential adverse effects to the physical environment. 19 references, 27 figures, 26 tables.

Aeropollen of weeds of the western United States Gulf Coast.  

PubMed

Volumetric air sampling was performed near Corpus Christi, Texas during all of 1988. The most significant weeds releasing airborne pollen, besides the Asteraceae, were the Amaranthaceae and Chenopodiaceae at 14.8% of total pollen captured, which peaked in September and October. Greater pollen capture (74%) occurred from a peak at 11 PM at a time when inversions are frequent to 9 AM than during the period from late morning to 9 PM. Frequency of amaranth-chenopod pollen capture in the western Gulf Coast region showed no relationship with frequencies along the northern and eastern Gulf Coast nor in eastern North America generally, but rather with western North America where these grains have also been sampled at high levels. As in the West, therefore, amaranth-chenopod aeropollen is sufficiently frequent to be a major source of allergens in the western Gulf Coast region. Other weedy plants, Cannabis/Humulus, Rumex, and the Urticaceae (Parieteria/Urtica) each account for only about 1% of the total annual pollen shed, and consequently they are not nearly as potentially relevant here in pollinosis as are the amaranth-chenopods and Asteraceae. Plantago pollen is very infrequently sampled (less than 0.1%) even though several species are common in the area. Acalypha is newly reported as releasing airborne pollen, a genus related to Mercurialis known to release allergenic pollen in Europe. PMID:1859040

ARkStorm: A West Coast Storm Scenario  

NASA Astrophysics Data System (ADS)

The United Stated Geological Survey (USGS) Multi-Hazards Demonstration Project (MHDP) is preparing a new emergency-preparedness scenario, called ARkStorm, to address massive U.S. West Coast storms analogous to those that devastated California in 1861-62. Storms of this magnitude are projected to become more frequent and intense as a result of climate change. The MHDP has assembled experts from the National Oceanic and Atmospheric Administration (NOAA), USGS, Scripps Institute of Oceanography, the State of California, California Geological Survey, the University of Colorado, the National Center for Atmospheric Research, and other organizations to design the large, but scientifically plausible, hypothetical scenario storm that would provide emergency responders, resource managers, and the public a realistic assessment of what is historically possible. The ARkStorm patterns the 1861 - 1862 historical events but uses modern modeling methods and data from large storms in 1969 and 1986. The ARkStorm draws heat and moisture from the tropical Pacific, forming Atmospheric Rivers (ARs) that grow in size, gain speed, and with a ferocity equal to hurricanes, slam into the U.S. West Coast for several weeks. Using sophisticated weather models and expert analysis, precipitation, snowlines, wind, and pressure data the modelers will characterize the resulting floods, landslides, and coastal erosion and inundation. These hazards will then be translated into the infrastructural, environmental, agricultural, social, and economic impacts. Consideration will be given to catastrophic disruptions to water supplies resulting from impacts on groundwater pumping, seawater intrusion, water supply degradation, and land subsidence. Possible climate-change forces that could exacerbate the problems will also be evaluated. In contrast to the recent U.S. East and Gulf Coast hurricanes, only recently have scientific and technological advances documented the ferocity and strength of possible future West Coast storms. A task of ARkStorm is to elevate the visibility of the very real threats to human life, property, and ecosystems posed by extreme storms on the U.S. West Coast. This enhanced visibility will help increase the preparedness of the emergency management community and the public to such storms. ARkStorm is scheduled to be completed by September 2010 and will be the basis of a state-wide emergency response drill, Golden Guardian, led by the California Emergency Management Agency in 2011.

Atlantic coast feeding habits of striped bass: A synthesis supporting a coast-wide understanding of trophic biology  

USGS Publications Warehouse

The recent increase in the Atlantic coast population of striped bass, Morone saxatilis (Walbaum), prompted managers to re-evaluate their predatory impact. Published and unpublished diet data for striped bass on the Atlantic Coast of North America were examined for geographical, ontogenetic and seasonal patterns in the diet and to assess diet for this species. Diets of young-of-the-year (YOY) striped bass were similar across the Upper Atlantic (UPATL), Chesapeake and Delaware Bays (CBDEL) and North Carolina (NCARO) areas of the Atlantic coast where either fish or mysid shrimp dominate the diet. For age one and older striped bass, cluster analysis partitioned diets based on predominance of either Atlantic menhaden, Brevoortia tyrannus (Latrobe), characteristic of striped bass from the CBDEL and NCARO regions, or non-menhaden fishes or invertebrates, characteristic of fish from the UPATL, in the diet. The predominance of invertebrates in the diets of striped bass in the UPATL region can be attributed to the absence of several important species groups in Northern waters, particularly sciaenid fishes, and to the sporadic occurrences of Atlantic menhaden to UPATL waters. In all regions, across most seasons and in most size classes of striped bass, the clupeiod fishes; menhaden, anchovies (Anchoa spp.) and river herrings (Alosa spp,) and Atlantic herring, Clupea harengus L., dominated the diets of striped bass above the first year of life.

PTSD reactions and coping responses of East Coast and West Coast American Airlines flight attendants after September 11: a possible psychological contagion effect?  

PubMed

Psychological reactions and functional coping of East Coast and West Coast-based flight attendants were compared after the attacks on September 11. Demographics and standardized questionnaires were sent in June 2002 to approximately 26,000 flight attendants. The 2,050 returned surveys were separated into East Coast-based flight crews (513 from Boston, New York, and Washington, DC) and West Coast-based flight crews (353 from Los Angeles and San Francisco). Despite demographic differences between the flight crews, most notably that the East Coast members were more than twice as likely to know someone who perished in the wake of September 11, there was no difference between them regarding probable PTSD (19.1% and 18.3%, respectively) or life functioning. We suggest that a psychological contagion effect occurred in this at-risk group of workers in the war on terrorism. Public health implications, including multicomponent treatment interventions, are suggested. PMID:15583512

The 2010 Chilean Tsunami Off the West Coast of Canada and the Northwest Coast of the United States  

NASA Astrophysics Data System (ADS)

The major ( M w = 8.8) Chilean earthquake of 27 February 2010 generated a trans-oceanic tsunami that was observed throughout the Pacific Ocean. Waves associated with this event had features similar to those of the 1960 tsunami generated in the same region by the Great ( M w = 9.5) 1960 Chilean Earthquake. Both tsunamis were clearly observed on the coast of British Columbia. The 1960 tsunami was measured by 17 analog pen-and-paper tide gauges, while the 2010 tsunami was measured by 11 modern digital coastal tide gauges, four NEPTUNE-Canada bottom pressure recorders located offshore from southern Vancouver Island, and two nearby open-ocean DART stations. The 2010 records were augmented by data from seven NOAA tide gauges on the coast of Washington State. This study examines the principal characteristics of the waves from the 2010 event (height, period, duration, and arrival and travel times) and compares these properties for the west coast of Canada with corresponding properties of the 1960 tsunami. Results show that the 2010 waves were approximately 3.5 times smaller than the 1960 waves and reached the British Columbia coast 1 h earlier. The maximum 2010 wave heights were observed at Port Alberni (98.4 cm) and Winter Harbour (68.3 cm); the observed periods ranged from 12 min at Port Hardy to 110-120 min at Prince Rupert and Port Alberni and 150 min at Bamfield. The open-ocean records had maximum wave heights of 6-11 cm and typical periods of 7 and 15 min. Coastal and open-ocean tsunami records revealed persistent oscillations that "rang" for 3-4 days. Tsunami energy occupied a broad band of periods from 3 to 300 min. Estimation of the inverse celerity vectors from cross-correlation analysis of the deep-sea tsunami records shows that the tsunami waves underwent refraction as they approached the coast of Vancouver Island with the direction of the incoming waves changing from an initial direction of 340° True to a direction of 15° True for the second train of waves that arrived 7 h later after possible reflection from the Marquesas and Hawaiian islands.

Giant Upper Cretaceous oysters from the Gulf coast and Caribbean  

USGS Publications Warehouse

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.

Pollution Levels in Fog at the Chilean Coast  

NASA Astrophysics Data System (ADS)

During July and August 2008 fog water was collected for chemical analysis in Patache, at the coast of northern Chile, 60 km south of Iquique (20°49’S, 70°09’W). Advective fog events occur regularly at the cliff in the coastal range at about 800 m above MSL. People collect these types of fog water at some places along the coast with Large Fog Collectors (LFC) for domestic use and for watering field crops. So far, no chemical analysis of fog water was performed in Patache. Pure fogwater samples (38 samples from 8 fog events) were taken by using a passive Scientific Cylindrical Fog Collector. Major ions and trace metals were quantified. The analyses indicate very high ionic concentrations (mean 3500 µeq/l) and very low pH values (mean 3.3). The mean H+-concentration represents 16 % of the total ionic equivalent concentration. Sulfate is the anion exhibiting the highest concentrations. A mean value of 880 µeq/l was found, which accounts for 24 % of the total mean concentration. In contrast to sulfate, nitrate shows only a low percentage of 8.1 %. Further major ions are sodium (20%) and chloride (19 %), which are typical seasalt ions in coastal fog. High correlations between the measured ions suggest a causal link between concentration in the fog samples and the liquid water content (LWC) of the cloud. The higher the liquid water content the lower are the ionic concentrations. Enrichment factors with sodium as reference ion were calculated to identify potential emission sources contributing to the observed pollutant levels. We found that K+, Na+, Mg2+ and Cl- mainly result from seaspray. Sulfate, however, is enriched by a factor of 13. The measured trace elements are highly enriched by factors up to hundreds of thousands (Zn: 50, Ni: 1800, As: 2400, Cd: 3900, Fe: 100000, Cu: 96000, Pb: 250000). A cluster analysis supports the conclusion that sulfate and the trace elements originate from anthropogenic activities. The sulfate cannot primarily originate from oceanic dimethylsulfide (DMS). With regard to the back trajectories, the air masses generally reach the study site from southerly directions after travelling along the Chilean coast. Presumably the air masses pick up pollutants in the densely populated cities, industrial plants and power plants along the Chilean coast and transport them over hundreds of kilometers to Patache. Here, they were detected as ingredients in fog water and lead to high pollution levels therein.

We have analyzed the spatial and temporal variability of chlorophyll in the Atlantic Ocean off the Portugal coast using satellite imagery from 1979 to 1986 in conjunction with wind data. The spatial patterns in the imagery show the typical inshore-offshore and east-west gradients, while the temporal patterns show seasonal high winter values and low summer values. In the satellite imagery for the period 1979-1986, stable mesoscale and large scale patterns recurred despite interannual differences in absolute satellite-derived pigment concentrations.

State of the Arctic Coast 2010: Scientific Review and Outlook  

NASA Astrophysics Data System (ADS)

The coast is a key interface in the Arctic environment. It is a locus of human activity, a rich band of biodiversity, critical habitat, and high productivity, and among the most dynamic components of the circumpolar landscape. The Arctic coastal interface is a sensitive and important zone of interaction between land and sea, a region that provides essential ecosystem services and supports indigenous human lifestyles; a zone of expanding infrastructure investment and growing security concerns; and an area in which climate warming is expected to trigger landscape instability, rapid responses to change, and increased hazard exposure. Starting with a collaborative workshop in October 2007, the International Arctic Science Committee (IASC), the Land-Ocean Interactions in the Coastal Zone (LOICZ) Project and the International Permafrost Association (IPA) decided to jointly initiate an assessment of the state of the Arctic coast. The goal of this report is to draw on initial findings regarding climate change and human dimensions for the Arctic as a whole provided by the Arctic Climate Impact Assessment (ACIA) and Arctic Human Development Report (AHDR) to develop a comprehensive picture of status and current and anticipated change in the most sensitive Arctic coastal areas. Underlying is the concept of a social ecological system perspective that explores the implications of change for the interaction of humans with nature. The report is aimed to be a first step towards a continuously updated coastal assessment and to identify key issues seeking future scientific concern in an international Earth system research agenda. The report titled “State of the Arctic Coast 2010: Scientific Review and Outlook” is the outcome of this collaborative effort. It is organized in three parts: the first provides an assessment of the state of Arctic coastal systems under three broad disciplinary themes - physical systems, ecological systems, and human concerns in the coastal zone; the second examines progress in integrative approaches to monitoring, understanding, and managing change in Arctic coastal systems; the third identifies data gaps and research priorities over the coming decade. The document was prepared by an international writing team, including 15 Lead Authors and 27 Contributing Authors. The draft report was released during the IPY Oslo Conference, 8-12 June 2010, and made available for public comments on the internet. This presentation provides an overview of the final report “State of the Arctic Coast 2010: Scientific Review and Outlook” which will be jointly published by IASC, LOICZ and IPA in early 2011.

Forecast of red tides off the Galician coast  

NASA Astrophysics Data System (ADS)

In Spain, mussels comprise around 90% of the total aquaculture production. Spanish mussel culture takes place almost exclusively in Galicia. The high productivity of the Galician coasts is a consequence of its western oceanic bound together with the seasonal northerly winds, generating strong upwelling of rich nutrient cold waters from May to September. When winds change to a southward direction, it results in a downwelling phenomenon which difficult the water renewal along the Galician Rias, contributing to the appearing of toxic blooms. The quantification on the degree of upwelling using the upwelling index serves as the basis for a predictive capability for harmful algal blooms (HABs). Where HABs occur at sufficient biomass, they may be detected by optical instruments, including ocean colour sensors on satellites together with sea surface temperature radiometers. Pairing of SST and pigment information allows the identification of key HAB processes and their relationship to physical dynamics. Results obtained in this study, indicate that there is a close relation between upwelling events, chlorophyll data, sea surface temperature and HABs. Therefore, all this parameters can be used to make a reliable prediction system of toxicity blooms in the Galician coast.

Colombian ocean waves and coasts modeled by special functions  

NASA Astrophysics Data System (ADS)

Modeling the ocean bottom and surface of both Atlantic and Pacific Oceans near the Colombian coast is a subject of increasing attention due to the possibility of finding oil deposits that haven't been discovered, and as a way of monitoring the ocean limits of Colombia with other countries not only covering the possibility of naval intrusion but as a chance to detect submarine devices that are used by illegal groups for different unwished purposes. In the development of this topic it would be necessary to use Standard Hydrodynamic Equations to model the mathematical shape of ocean waves that will take differential equations forms. Those differential equations will be solved using computer algebra software and methods. The mentioned solutions will involve the use of Special Functions such as Bessel Functions, Whittaker, Heun, and so on. Using the Special Functions mentioned above, the obtained results will be simulated by numerical methods obtaining the typical patterns around the Colombian coasts (both surface and bottom). Using this simulation as a non-perturbed state, any change in the patter could be taken as an external perturbation caused by a strange body or device in an specific area or region modeled, building this simulation as an ocean radar or an unusual object finder. It's worth mentioning that the use of stronger or more rigorous methods and more advanced Special Functions would generate better theoretical results, building a more accurate simulation model that would lead to a finest detection.

The pacific coast: a reluctant area of promise  

SciTech Connect

America's first offshore well was drilled from a wooden pier extending outward from the coastal town of Summerland, Calif., just east of Santa Barbara. That was in 1894, and in the 90 years since then some 4,000 additional wells have been drilled off the California coast. But the region still qualifies as a legitimate Area of Promise because those 4,000 wells account for only 13% of all U.S. offshore wells, and leases offshore California accounted for only 7% of the 12.6 million acres under lease around the U.S. as of the end of 1982. platform plans already have been announced. But installing the platforms won't be without problems-most of them caused by the environmental concerns of coastal residents. During the course of drilling 30,000 wells around the U.S. there has been only one serious mishap. And that, unfortunately, was the 1969 Santa Barbara blowout. Besides coating beaches and wildlife along the Santa Barbara Channel with crude oil, the blowout had a more-lasting effect in that it galvanized and unified the environmental movement. So now there is a virtual cartel of some 30 environmental groups that must be dealt with by oil companies that want to drill offshore the U.S. Pacific Coast.

Comparative analysis of sediments from the coast of southern California  

SciTech Connect

Sediment samples were collected in the summer of 1994 along the coast of the Southern California Bight, from Point Conception to the boarder with Mexico. Agencies involved in the program included EPA (EMAP), NOAA (ORCA), the state of California (State Water Board, California Dept. of Fish and Game, the University of Calif., Santa Cruz), major municipal waste dischargers (cities of Los Angeles and San Diego, Los Angeles and Orange Counties), and their research organization, SCCWRP. The level of effort in certain regions (bays) was more intensive than on the open coast, since there was an attempt to find ``hot spots``. For some of these sites the sediments were analyzed for inorganic and organic contaminants, toxicity to amphipods and echinoderm larvae, and a biomarker (P450 reporter gene system; RGS). The findings from chemical and biological testing on sediments from Orange County to San Diego Bay will be presented to demonstrate the range of contamination and the responses of the test species. Further comparisons between the concentrations of key contaminants and biological measures of toxicity will describe the correlations found, and the likelihood of identifying hot spots with toxicological endpoints. A strong correlation was found for the relationship between PAHs in sediments and the induction of P450 in a screening test system (RGS).

Modeling the population dynamics of Gulf Coast sandhill cranes  

USGS Publications Warehouse

The Midcontinental population of sandhill cranes (Grus canadensis) has a large geographic range, contains nearly 500,000 birds, and is hunted in much of its range. The population includes three subspecies; the numbers of two of these are uncertain, and they should be afforded protection from hunting that would be detrimental to their population. The two subspecies of concern tend to concentrate in the eastern part of the Great Plains during fall and spring and to winter along the Gulf Coast in Texas. This paper uses the limited information available about the Gulf Coast subpopulation in a model. We included in the model five input parameters: population size, annual survival rate in absence of hunting, the number of birds taken by hunters, the extent of additivity of hunting mortality, and recruitment rate, measured as the fraction of juveniles in the winter population. Using three widely ranging estimates of each parameter, we examined the general behavior of the simulated population. Realistic population projections occurred with medium (60,000) or large (166,000) population sizes, low (2000) or moderate (4000) harvests, and recruitment rates of 0.07 and 0.11. All values of survival in the absence of hunting and additivity of hunting yielded some realistic projections. Results of modelling suggest that the variables warranting closer monitoring are population size and recruitment rate.

Holocene Glacial Retreat at Walgreen Coast, West Antarctica  

NASA Astrophysics Data System (ADS)

The Walgreen Coast of West Antarctica represents one of the most rapidly changing sectors of the West Antarctic Ice Sheet (WAIS). With the fastest ice streams in the whole Antarctic, the WAIS is characterised by rapid thinning and grounding line retreat. Airborne and satellite-based short-term observations show a doubling of the negative net mass balance between 1996-2006 (Rignot et al., 2008). Furthermore, because the WAIS is largely grounded below sea level, continued inland thinning and grounding line retreat could result in rapid ice sheet collapse, which would raise global sea level by between 3-5 m. However, due to remoteness and challenging accessibility, onshore data is limited to a few isolated nunataks making it difficult to assess the long-term evolution of the glacial dynamics along Walgreen Coast. To address this we present new data from two key areas of the Walgreen Coast; the Kohler Range and the Pine Island Bay. Our 10Be surface exposure ages from erratic boulders in the Kohler Range are the first and reveal that this area became ice-free between 8.3 and 12.3 ka. This implies a long-term thinning rate of 3.3 cm/yr and agrees with similar data published from glaciers eastward. Our ages are also consistent with recent deglaciation models which suggest strong thinning after 15 ka and off-shore sediments shows a concurrent lateral ice-shelf front retreat. Our results suggest an ice-cover at least 300 m thicker in the Kohler Range during the early Holocene and that subsequent average thinning occurred on rates one order of magnitude slower than recent satellite measurements show. This implies that the recent trend in ice-sheet thinning results from a recent dynamic changes rather than a response to long-term thinning. To further constrain the lateral deglaciation history along the eastern Walgreen Coast, namely the Pine Island Glacier, we collected additional samples from a chain of islands, located flow-parallel and downstream of the ice-shelf front. We will use this new 10Be surface exposure data to infer whether the uncovering of these islands results from glacial retreat and/or subsequent isostatic rebound. Together, our new data will contribute to a better understanding of long-term glacial thinning along the West Antarctic coast, and thus provides new constraints for ice sheet models helping to predict the future behaviour of the WAIS.

Headland sediment bypassing and beach rotation in a rocky coast: an example at the western Portuguese coast  

NASA Astrophysics Data System (ADS)

Headland sediment bypassing plays a major role in definition of coastal sedimentary budget and consequently in coastal management. This process is particularity important at headland-bay beaches on rocky coasts. However, headland-bay beach research is usually focused on the beach rotation since these beaches are generally regarded as closed systems. The sediment bypassing mechanisms have been extensively studied in the context of artificial structures (e.g. groins and jetties) but studies of natural headland sediment bypassing are scarce and usually applied to decadal time scales. This work aims to contribute to the understanding of headland sediment bypassing processes in non-artificial environments, taking as a case study a natural coastal stretch at the Portuguese west coast. The study is supported on the analysis of planform beach changes using Landsat satellite images (with an acquisition frequency of 16 days) complemented with field surveys with DGPS-RTK and ground-based photographic monitoring. The study area can be described as a cliffed rocky coast that accommodates a series of headland-bay beaches with different geometries: some are encased in the dependence of fluvial streams, while others correspond to a narrow and elongated thin sand strip that covers a rocky shore platform. This coast is generally characterized by a weak, but active, sediment supply and high levels of wave energy due to the exposure to the swells generated in the North Atlantic. The long-term stability of the beaches in conjunction with active sediment supply along the study area (from streams and cliff erosion) and a sink at the downdrift end of this coastal stretch (an active dune system) support the existence of headland sediment bypassing. The analysis of planform beach changes show a coherent signal in time but with a range that depends on the orientation of the stretch where each beach is included. In general, beaches displays a clockwise rotation during summer related to the NW (less energetic) incident wave conditions. The persistence of these conditions induces an enlargement of the beach downdrift (southward) and eventually sediment bypassing. This process can result in a continuous inner bar along the headland coast, which migrates downdrift in the surf zone and weld to the downdrift beach. The counter-clockwise rotation observed in the winter is more variable being in agreement with the less persistent W and SW incident wave conditions, suggesting that sediment bypassing occurs only southwards. The work was funded by FEDER funds through the Operational Programme for Competitiveness Factors - COMPETE and FCT National Funds - Portuguese Foundation for Science and Technology under the project Beach to Canyon Head Sedimentary Processes (PTDC/MAR/114674/2009). First author benefits from a PhD grant funded by FCT (SFRH/BD/79126/2011).

Evolving Shoreline Change Rates Along the US Pacific Northwest Coast  

NASA Astrophysics Data System (ADS)

Coastal change hazards are increasingly affecting economically important areas, including those used for infrastructure, commerce, and public recreation. Quantifying shoreline change rates and understanding the contributing factors is crucial to protect these areas and to assist federal, state, and local agencies in developing long-term management plans. A recent study by the USGS National Assessment of Shoreline Change project analyzed the historical shoreline record along the U.S. Pacific Northwest with emphasis on both century-scale (1800s--2002) and decadal-scale (1960-80s--2002) change rates (Ruggiero, P., Kratzmann, M.A., Himmelstoss, E.G., Reid, D., Allan, J., and Kaminsky, G., 2013: U.S. Geological Survey Open-File Report 2012-1007, 55 p.). The study was the first consistent state-wide coastal change assessment for Oregon and revealed a significant increase in erosion hazards in the near-term. The coastal landscape in Oregon is particularly dynamic and includes beaches that are backed by both cliffs and dunes, and range in texture from sand to cobble. The high wave energy in the Pacific Northwest results in a morphology with primarily intermediate to dissipative beaches. Resistant rocky headlands separate the Oregon coast into 18 distinct littoral cells, greatly influencing how the shoreline changes with time. While the century-scale average of all 560 km of Oregon coastline suggests the shore is prograding at 0.4 m/yr, the decadal-scale record indicates that 13 of the 18 littoral cells either are accreting at a slower rate, have changed from accretional to erosional, or are eroding at a faster rate. This apparent increase in erosion-affected coasts may be caused by several factors including sea-level rise, increasing storm wave heights, tectonic uplift, and climatic events (eg., El Niño), but overall it indicates a shifting trend in shoreline change rates. In the present study, we quantify shoreline change rates on a third timescale, seasonal to interannual, to further investigate coastal change hazards along the Oregon coast. The Oregon Department of Geology and Mineral Industries (DOGAMI) has surveyed several sites along Oregon's coastline at least annually since approximately the late 1990s. Shoreline positions are obtained either from beach profiles collected with Real Time Kinematic Differential GPS (RTK-DGPS) technology or extracted from lidar data. For consistency, we analyze shoreline change at the same transect locations as those used in the National Assessment, with the same analysis software, the USGS Digital Shoreline Analysis System (DSAS) within ArcGIS. With this approach, our study directly compares change rates at three distinct time scales yielding new insights into Oregon's shoreline evolution.

Patterns of significant seismic quiescence in the Pacific Mexican coast  

NASA Astrophysics Data System (ADS)

Mexico is one of the countries with higher seismicity. During the 20th century, 8% of all the earthquakes in the world of magnitude greater than or equal to 7.0 have taken place in Mexico. On average, an earthquake of magnitude greater than or equal to 7.0 occurred in Mexico every two and a half years. Great earthquakes in Mexico have their epicenters in the Pacific Coast in which some seismic gaps have been identified; for example, there is a mature gap in the Guerrero State Coast, which potentially can produce an earthquake of magnitude 8.2. With the purpose of making some prognosis, some researchers study the statistical behavior of certain physical parameters that could be related with the process of accumulation of stress in the Earth crust. Other researchers study seismic catalogs trying to find seismicity patterns that are manifested before the occurrence of great earthquakes. Many authors have proposed that the study of seismicity rates is an appropriate technique for evaluating how close a seismic gap may be to rupture. We designed an algorithm for identification of patterns of significant seismic quiescence by using the definition of seismic quiescence proposed by Schreider (1990). This algorithm shows the area of quiescence where an earthquake of great magnitude will probably occur. We apply our algorithm to the earthquake catalogue of the Mexican Pacific coast located between 14 and 21 degrees of North latitude and 94 and 106 degrees West longitude; with depths less or equal to 60 km and magnitude greater or equal to 4.2, which occurred from September, 1965 until December, 2014. We have found significant patterns of seismic quietude before the earthquakes of Oaxaca (November 1978, Mw = 7.8), Petatlán (March 1979, Mw = 7.6), Michoacán (September 1985, Mw = 8.0, and Mw = 7.6) and Colima (October 1995, Mw = 8.0). Fortunately, in this century have not occurred earthquakes of great magnitude in Mexico, however, we have identified well-defined seismic quiescence in the Guerrero seismic-gap, which are apparently correlated with the occurrence of silent earthquakes in 2002, 2006 and 2011 recently discovered by GPS technology. In fact, a possible silent earthquake with Mw =7.6 occurred at this gap in 2002 which lasted for approximately 4 months and was detected by continuous GPS receivers located over an area of ~550x250 square kilometers.

A coastal hazards data base for the US Gulf Coast  

SciTech Connect

This document describes the contents of a digital data base that may be used to identify coastlines along the US Gulf Coast at risk to sea-level rise. The data base integrates point, line, and polygon data for the US Gulf Coast into 0.25{degree} latitude by 0.25{degree} longitude grid cells and into 1:2,000,000 digitized line segments that can be used by raster or vector geographic information systems (GIS) as well as by non-GIS data base systems. Each coastal grid cell and line segment contains data on elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. To allow for the identification of coastlines at risk from sea-level rise, 7 of the 22 original data variables in this data base were classified by vulnerability and used to create 7 relative risk variables. These relative risk variables range in value from 1 to 5 and may be used to calculate a coastal vulnerability index for each grid cell and/or line segment. The data for these 29 variables (i.e., the 22 original variables and 7 risk variables) have been placed into the following data formats: (1) Gridded polygon data for the 22 original data variables. Data include elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. (2) Gridded polygon data for the seven classified risk variables. The risk variables are classified versions of: mean coastal elevation, geology, geomorphology, local subsidence trend, mean shoreline displacement, maximum tidal range, and maximum significant wave height. (3) 1:2,000,000 line segment data containing the 29 data variables (the 22 original data variables and the seven classified risk variables). (4) Supplemental point data for the stations used in calculating the sea-level trend and tidal range data sets. (5) Supplemental line segment data containing a 1:2,000,000 digitized coastline of the US Gulf Coast as defined by this document.
