    Arbovirus diseases have emerged as a global public health concern. However, the impact of climatic, social, and environmental variability on the transmission of arbovirus diseases remains to be determined. Our goal for this study was to provide an overview of research development and future research directions about the interrelationship between climate variability, social and environmental factors, and the transmission of Ross River virus (RRV), the most common and widespread arbovirus disease in Australia. We conducted a systematic literature search on climatic, social, and environmental factors and RRV disease. Potentially relevant studies were identified from a series of electronic searches. The body of evidence revealed that the transmission cycles of RRV disease appear to be sensitive to climate and tidal variability. Rainfall, temperature, and high tides were among major determinants of the transmission of RRV disease at the macro level. However, the nature and magnitude of the interrelationship between climate variability, mosquito density, and the transmission of RRV disease varied with geographic area and socioenvironmental condition. Projected anthropogenic global climatic change may result in an increase in RRV infections, and the key determinants of RRV transmission we have identified here may be useful in the development of an early warning system. The analysis indicates that there is a complex relationship between climate variability, social and environmental factors, and RRV transmission. Different strategies may be needed for the control and prevention of RRV disease at different levels. These research findings could be used as an additional tool to support decision making in disease control/surveillance and risk management.

    The Ross Sea is underlain from the east to the west by three north-south-trending sedimentary basins: the Eastern basin (east of the 180/sup 0/ meridian), the Central basin (along 175/sup 0/), and the Victoria Land basin. In the center of the Eastern basin, the thickness of the sediments generally ranges between 3000 and 6000 m. The pre-late Oligocene sediments occur only in the center of the basin. There are no indications of block faulting in the sedimentary sequence, indicating that synsedimentary subsidence has been the dominant tectonic process. A broad basement high, the Central High, lies to the west of the Eastern basin. The top of basement is a peneplain over large parts of the high. The overlying sediments are mostly younger than Oligocene. The Central basin lies to the west of the Central High, extends approximately north-south through the central Ross Sea. Sedimentary thicknesses in excess of 6000 m were observed. A relatively narrow basement high, trending north-south, separates the Central basin from the complex Victoria Land basin. The Victoria Land basin is a 150-km wide basin that extends from the Ross Ice shelf to 75/sup 0/S. It is bounded to the north by a shallow and characteristically planated basement high, the Coulman High, and to the west by the uplifted Transantarctic Mountains. The Victoria Land basin is subdivided by north-south-trending zones of volcanic/magmatic intrusions, probably equivalents of the Neogene Hallett Volcanics and McMurdo Volcanics, respectively, that affected the Victoria Land basin, resulting in uplift and inversion of parts of the basin.

    In Australia, Ross River virus (RRV) is predominantly identified and managed through passive health surveillance. Here, the proactive use of environmental datasets to improve community-scale public health interventions in southeastern Tasmania is explored. Known environmental drivers (temperature, rainfall, tide) of the RRV vector Aedes camptorhynchus are analysed against cumulative case records for five adjacent local government areas (LGAs) from 1993 to 2009. Allowing for a 0- to 3-month lag period, temperature was the most significant driver of RRV cases at 1-month lag, contributing to a 23·2% increase in cases above the long-term case average. The potential for RRV to become an emerging public health issue in Tasmania due to projected climate changes is discussed. Moreover, practical outputs from this research are proposed including the development of an early warning system for local councils to implement preventative measures, such as public outreach and mosquito spray programmes.

    Seabirds have substantial influence on geochemical circulation of elements, serving as a link for substance exchange between their foraging area and colonies. In this study, we investigated the elemental and carbon isotopic composition of five penguin-affected sediment profiles excavated from Ross Island and Beaufort Island in the Ross Sea region, Antarctica. Among the three main constituents of the sediments (including weathered bedrock, guano and algae), guano was the main source of organic matter and nutrients, causing selective enrichment of several elements in each of the sediment profiles. In the 22 measured elements, As, Cd, Cu, P, S, Se and Zn were identified as penguin bio-elements in the Ross Sea region through statistical analysis and comparison with local end-member environmental media such as weathered bedrock, fresh guano and fresh algae. Carbon isotopic composition in the ornithogenic sediments showed a mixing feature of guano and algae. Using a two-member isotope mixing equation, we were able to reconstruct the historical change of guano input and algal bio-mass. Compared with research in other parts of Antarctic, Arctic, and South China Sea, we found apparent overlap of avian bio-elements including As, Cd, Cu, P, Se, and Zn. Information on the composition and behavior of bio-elements in seabird guano on a global scale, and the role that bio-vectors play in the geochemical circulation between land and sea, will facilitate future research on avian ecology and paleoclimatic reconstruction.

    An interdisciplinary team of researchers will focus on describing the high productivity patchiness observed in phytoplankton blooms in the mid-to-late summer in the Ross Sea, Antarctica. They will use a novel sampling strategy that employs a remotely controlled glider (AUV) to locate and map circumpolar deep water in near real time and also to direct further ship-based sampling. This unusual coordination of a polar research vessel with AUVs provides an exciting opportunity to engage formal and informal educators in a research adventure. As part of this NSF-funded project’s Criterion 2 broader impact, joining the researchers virtually will be 30 New Jersey middle-school teachers and their students. This summer in New Jersey, in partnership with Liberty Science Center educators, COSEE-NOW (Centers for Ocean Sciences Education Excellence-Networked Ocean World) and Woods Hole Oceanographic Institution, the project team introduced teachers to the Ross Sea, the research, the science behind it and the AUV. The summer workshop and ongoing schoolyear support is providing the teachers with the tools they need to bring the excitement of the research into their classrooms in real time during the Ross Sea cruise at the end of this year. This presentation by Chris Parsons, the project evaluator, will summarize the evaluation plan for this broader impact project, which follows teachers and their classes for a year, and provide the latest evaluation results from this project.

    Distributions of Antarctic krill (Euphausia superba), crystal krill (Euphausia crystallorophias), and Antarctic silverfish (Pleuragramma antarcticum) were constructed using observations collected in the western Ross Sea from 1988-2004. Distributions of mixed layer depth (MLD), water temperature below 200 m (an indicator for Circumpolar Deep Water, CDW), and surface speed were obtained from a Ross Sea circulation model; surface chlorophyll and percent sea ice coverage were obtained from satellite observations. The species and environmental distributions were analyzed to determine patterns and correlations. Statistical analyses of the distributions show that the three species are concentrated in specific regions and that their habitats have limited overlap. Antarctic krill are concentrated along the shelf break near Cape Adare and are associated with temperatures >0.5°C and -2°C to -0.75°C, 19-32% sea ice coverage, and high surface flow speeds. Crystal krill are concentrated in Terra Nova Bay in areas with depths of 400-600 m, temperatures < -1.3°, 50% or more sea ice coverage, shallow MLDs (2-36 m), moderate concentrations of chlorophyll (0.44 μg m-3) and low surface speeds (0.08 m s-1). Similarly, Antarctic silverfish are concentrated in Terra Nova Bay and are also found over the continental shelf in areas with depths of 500 m and temperatures of -2°C to -1°C. Additional statistical analyses provide insights into the relative contribution of the different environmental features to producing the distributions of the three species.

    Ross Sea phytoplankton, generally dominated by diatoms and Phaeocystis antarctica, play an essential biogeochemical role in this highly biologically productive Southern Ocean region. Although associations between these phytoplankton and environmental factors such as temperature, vertical mixing, and irradiance have been documented, the causal mechanisms among these interactions and extent to which they are modified by altered climatic conditions are poorly understood. To investigate these relationships, data from a 2012 glider deployment are analyzed in conjunction with model experiments performed using a modified version of the multi-component Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification (MEDUSA) run within the Marine Model Optimization Testbed (MarMOT), a one-dimensional data assimilative analysis framework. Specifically, MEDUSA has been adapted for the Ross Sea by including both solitary and colonial forms of P. antarctica and irradiance-Fe interactions. After evaluating model performance with glider observations of chlorophyll and particulate organic carbon, scenario experiments are conducted investigating how the magnitude and phenology of spring and summer phytoplankton are likely to be modified by a future altered climate. In particular, the relative impacts of potential increased water temperatures on phytoplankton productivity will be assessed, through differences in biological rates, increased iron and light availability from melting ice, and increased stratification. Variability in phytoplankton productivity resulting from these effects of warming temperatures are analyzed individually and in combination to evaluate the relative importance of these drivers of change in the biogeochemical environment of the Ross Sea.

    We used geographic information systems and a spatial analysis approach to explore the pattern of Ross River virus (RRV) incidence in Brisbane, Australia. Climate, vegetation and socioeconomic data in 2001 were obtained from the Australian Bureau of Meteorology, the Brisbane City Council and the Australian Bureau of Statistics, respectively. Information on the RRV cases was obtained from the Queensland Department of Health. Spatial and multiple negative binomial regression models were used to identify the socioeconomic and environmental determinants of RRV transmission. The results show that RRV activity was primarily concentrated in the northeastern, northwestern, and southeastern regions in Brisbane. Multiple negative binomial regression models showed that the spatial pattern of RRV disease in Brisbane seemed to be determined by a combination of local ecologic, socioeconomic, and environmental factors.

    Krill, a key pelagic resource of the Antarctic food web, provides an important link between primary and secondary plankton production and top predators. Since krill abundance is a crucial factor in Antarctic ecosystem functioning, its monitoring supplies vital data. Acoustic surveys are an effective approach to estimating krill abundance. An acoustic survey was conducted in the western Ross Sea in January 2014-10 years after a similar survey by our team - to estimate krill abundance and biomass and monitor oceanographic conditions. Antarctic krill (Euphausia superba) was detected in the northern part of the western Ross Sea and dense swarms of ice krill (Euphausia crystallorophias) were found in its central coastal area. Data analysis revealed an inverse correlation between E. superba density and salinity in the water column, whereas a positive correlation was found between E. crystallorophias abundance and fluorescence; the latter relationship was confirmed in thematic maps of E. crystallorophias spatial distribution and fluorescence. Comparison of 2004 and 2014 biomass data showed a much greater abundance of both species in the more recent survey.

    2014-10-01

    Ross River virus (RRV) is the most common vector-borne disease in Australia. It is vitally important to make appropriate projections on the future spread of RRV under various climate change scenarios because such information is essential for policy-makers to identify vulnerable communities and to better manage RRV epidemics. However, there are many methodological challenges in projecting the impact of climate change on the transmission of RRV disease. This study critically examined the methodological issues and proposed possible solutions. A literature search was conducted between January and October 2012, using the electronic databases Medline, Web of Science and PubMed. Nineteen relevant papers were identified. These studies demonstrate that key challenges for projecting future climate change on RRV disease include: (1) a complex ecology (e.g. many mosquito vectors, immunity, heterogeneous in both time and space); (2) unclear interactions between social and environmental factors; and (3) uncertainty in climate change modelling and socioeconomic development scenarios. Future risk assessments of climate change will ultimately need to better understand the ecology of RRV disease and to integrate climate change scenarios with local socioeconomic and environmental factors, in order to develop effective adaptation strategies to prevent or reduce RRV transmission.

    Landsat/Seasat remote sensing was used by Ames Research Center to evaluate environmental influence on ancient Mayan civilization. Over 35 archeological sites were imaged and valuable information concerning Maya settlement patterns, environment, and resource usage resulted. The imagery was also used by Mexican authorities to develop coastal management plans, establish Biosphere Reserves and assess damage from the 1988 Hurricane Gilbert. Imagery showed evidence of ancient coastlines, changes in sea level, an ancient river plain and Mayan canal systems. Previously unknown Mayan reservoirs were discovered. The project is considered a pioneering effort combining remote sensing, environmental studies and archeology.

    Deglaciation of the Ross Sea following the last ice age provides an important opportunity to examine the stability of marine ice sheets and their susceptibility to changing environmental conditions. Insufficient chronology for Ross Sea deglaciation has helped sustain (i) the theory that this region contributed significantly to Meltwater Pulse 1A (MWP-1A) and (ii) the idea that Ross Sea grounding-line retreat occurred in a "swinging gate" pattern hinged north of Roosevelt Island. We present deglaciation records from southern Transantarctic Mountain glaciers, which delivered ice to the central Ross Sea. Abrupt thinning of these glaciers 9-8 kyr B.P. coincided with deglaciation of the Scott Coast, ˜800 km to the north, and ended with the Ross Sea grounding line near Shackleton Glacier. This deglaciation removed grounded ice from most of the central and western Ross Sea in less than 2 kyr. The Ross Sea Sector neither contributed nor responded significantly to MWP-1A.

The geographic South Pole is located in the center of Antarctica, at an altitude of 2,900 meters (9,300 feet). It rests on a continent-wide ice sheet that is 2,870 m thick, with the underlying bedrock only 30 m (98 feet) above sea level. The ice underlying the South Pole is as much as 140,000 years old, and is currently accumulating at about 82 cm (32 inches) per year. Roughly 2,500 km (1,550 miles) away is the green water of the Ross Sea, which indicates the presence of large numbers of phytoplankton. This is a highly productive part of the world's oceans. Also note the ice gathered around McMurdo Sound, seen toward the lefthand shoreline of the Ross Sea, at the edge of the Ross Ice Shelf. According to National Science Foundation researchers, this ice is making it difficult for penguins to reach their food supply.

  14. Research priorities in environmental health.

    Pershagen, G

    1999-06-19

    Environmental issues tend to greater political attention than do environmental health aspects. Therefore, when conflicts of interest occur with other environmental concerns, negative consequences for public health may result. For example, a strategy to substantially reduce indoor ventilation in many dwellings in Scandinavia in order to save energy has led to increased humidity levels and higher prevalences of house dust mites. Wood burning for local heating is promoted because it is a renewable source of energy, and diesel vehicles are promoted because they emit lower levels of carbon dioxide per kilometer compared to conventional gas engines, but both practices lead to increased emissions of fine particulates, which have been associated with adverse health effects. Increasing the level of resources available for research into environmental health is one way to help environmental health issues receive greater attention. Environmental health research initiatives taken by the European Commission, the European Science Foundation, and the World Health Organization's regional office for Europe are noted. Environmental health research is multidisciplinary and should encompass basic science as well as applied research. International collaboration is often very useful in environmental health research.

    Transdisciplinary research, involving close collaboration between researchers and the users of research, has been a feature of environmental problem solving for several decades, often spurred by the need to find negotiated outcomes to intractable problems. In 2005, the Australian government allocated funding to its environment portfolio for public good research, which resulted in consecutive four-year programmes (Commonwealth Environmental Research Facilities, National Environmental Research Program). In April 2014, representatives of the funders, researchers and research users associated with these programmes met to reflect on eight years of experience with these collaborative research models. This structured reflection concluded that successful multi-institutional transdisciplinary research is necessarily a joint enterprise between funding agencies, researchers and the end users of research. The design and governance of research programmes need to explicitly recognise shared accountabilities among the participants, while respecting the different perspectives of each group. Experience shows that traditional incentive systems for academic researchers, current trends in public sector management, and loose organisation of many end users, work against sustained transdisciplinary research on intractable problems, which require continuity and adaptive learning by all three parties. The likelihood of research influencing and improving environmental policy and management is maximised when researchers, funders and research users have shared goals; there is sufficient continuity of personnel to build trust and sustain dialogue throughout the research process from issue scoping to application of findings; and there is sufficient flexibility in the funding, structure and operation of transdisciplinary research initiatives to enable the enterprise to assimilate and respond to new knowledge and situations.

    Donald Ross introduced the pulmonary autograft for aortic valve replacement with reconstruction of the right ventricular outflow tract with a homograft. Despite its advantages over conventional valve prostheses, the Ross Operation is performed in a minority of patients who need an aortic valve replacement throughout the world. To report the operative and long term results of a series of patients subjected to Ross operation in Chile. Between 1996 and 2006, 131 patients aged 35+/-11 years (62% males) were subjected to an aortic root replacement with a pulmonary autograft and reconstruction of the right ventricular outflow tract with a pulmonary homograft. Seventy percent had congenital valve disease. Associated procedures were done in 39%. Patients were followed for a mean of 56+/-30 months. Operative mortality was 2.3%. Two patients had the autografts replaced intraoperatively because of tears in the proximal suture line and one within a month of the operation after suffering autograft endocarditis. At last follow up all patients are in functional class 1 or 2. Autograft reoperations were done in two patients who developed dilation with valve regurgitation (both had aortic regurgitation as primary indication for aortic valve replacement). Three patients required reoperation for pulmonary homograft dysfunction. Another three patients had uneventful pregnancies with normal newborns. Actuarial freedom from any reoperation at 10 years is 93%. The Ross Operation has low operative morbidity and mortality with excellent long term results. Reoperations have been rare within 10 years of follow up both for the autograft or the homograft.

Floating, microscopic plants, known as phytoplankton, soak up the sunlight and the nutrients stirring in the Southern Ocean and grow into prodigious blooms. Those blooms become a great banquet for krill, fish, penguins, whales, and other marine species who carve out a living in the cool waters of the far south. This true-color image captures such a bloom in the Ross Sea on January 22, 2011, as viewed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Bright greens of plant-life have replaced the deep blues of open ocean water. The Ross Sea is a relatively shallow bay in the Antarctic coastline and due south from New Zealand. As the spring weather thaws the sea ice around Antarctica, areas of open water surrounded by ice—polynyas—open up on the continental shelf. In this open water, sunlight provides the fuel and various current systems provide nutrients from deeper waters to form blooms that can stretch 100 to 200 kilometers (60 to 120 miles). These blooms are among the largest in extent and abundance in the world. Scientists have hypothesized that the Modified Circumpolar Deep Water is the engine behind the blooms, stirring up just the right mix of trace metals and minerals from the deep to sustain plankton growth.

  2. Ross Ice Shelf Seismic Survey and Future Drilling Recommendation

    NASA Astrophysics Data System (ADS)

    2016-04-01

    The Ross Ice Shelf (RIS) is one of three gateways through which change in the ocean can be propagated into the interior of West Antarctica. Both the geologic record and ice sheet models indicate that it has experienced widespread retreat under past warm climates. But inland of the continental shelf, there are limited data available to validate the models. Understanding what controls the rate at which the ice shelf will respond to future climate change is central to making useful climate projections. Determining the retreat rate at the end of the last glacial maximum is one part of this challenge. In November 2015, four lines of multi-channel seismic data, totalling over 45 km, were collected on the Ross Ice Shelf, approximately 300 km south of Ross Island using a thumper seismic source and a 96 channel snow streamer. The seismic survey was undertaken under the New Zealand Antarctic Research Institute (NZARI) funded Aotearoa New Zealand Ross Ice Shelf Programme to resolve bathymetric details and to image sea floor sediments under a proposed drilling site on the ice shelf, at about 80.7 S and 174 E. The thumper, a purpose-built, trailer mounted, weight-drop seismic source was towed behind a Hägglund tracked vehicle to image the bathymetry and sediments underneath the RIS. Seismic data collection on an ice shelf has unique challenges, in particular strong attenuation of the seismic energy by snow and firn, and complex multiple ray paths. The thumper, which consists of a heavy weight (250kg) that is dropped on a large, ski mounted steel plate, produced a consistent, repeatable higher energy signal when compared to sledge hammer source and allowed for a greater geographic coverage and lower environmental impact than an explosive source survey. Our survey revealed that the seafloor is smooth and that there may be up to 100 m of layered sediments beneath the seafloor and possibly deeper, more complex structures.

    Two large icebergs, designated B-15A and C-16, are captured in this MISR nadir camera view of the Ross Ice Shelf and Ross Sea in Antarctica. The image was acquired on December 10, 2000 during Terra orbit 5220.

    Iceberg C-16 calved off the ice shelf in late September and is nearly 50 kilometers in length. It is seen here having migrated to the vicinity of Cape Bird on Ross Island. The initial letter designation in an iceberg's name denotes the longitudinal quadrant in which it is first seen, and new icebergs sighted in that quadrant are sequentially numbered. B-15 divided from the ice shelf last March, and initially was nearly as large as the state of Connecticut. It has since broken up into several pieces, hence the final letter designation in the berg shown in this image.

    Ross Island lies between 77 and 78 degrees south latitude, and consists of several volcanic peaks, of which the still active Mt. Erebus is the tallest (3794 meters). It overlooks McMurdo Station, a U.S. research facility located near the tip of the island's Hut Point Peninsula.

    Broadband seismic stations were deployed across the Ross Ice Shelf (RIS) in November 2014 to study ocean gravity wave-induced vibrations. Initial data from three stations 100 km from the RIS front and within 10 km of each other show both dispersed infragravity (IG) wave and ocean swell-generated signals resulting from waves that originate in the North Pacific. Spectral levels from 0.001 to 10 Hz have the highest accelerations in the IG band (0.0025-0.03 Hz). Polarization analyses indicate complex frequency-dependent particle motions, with energy in several frequency bands having distinctly different propagation characteristics. The dominant IG band signals exhibit predominantly horizontal propagation from the north. Particle motion analyses indicate retrograde elliptical particle motions in the IG band, consistent with these signals propagating as Rayleigh-Lamb (flexural) waves in the ice shelf/water cavity system that are excited by ocean wave interactions nearer the shelf front.

    Iceberg B-15 broke from the Ross Ice Shelf in Antarctica in late March. Among the largest ever observed, the new iceberg is approximately 170 miles long x 25 miles wide. Its 4,250 square-mile area is nearly as large as the state of Connecticut. The iceberg was formed from glacial ice moving off the Antarctic continent and calved along pre-existing cracks in the Ross Ice Shelf near Roosevelt Island. The calving of the iceberg essentially moves the northern boundary of the ice shelf about 25 miles to the south, a loss that would normally take the ice shelf as long as 50-100 years to replace.

  14. The Ross II procedure: pulmonary autograft in the mitral position.

    2004-10-01

    The surgical management of mitral valve disease in women of childbearing age, young patients, and children with congenital mitral valve defects is made difficult by the prospect of lifelong anticoagulation. We suggest the use of a pulmonary autograft in the mitral position (Ross II procedure) as an alternative surgical technique. We present a review of the literature, historical perspectives, indications, selection criteria, and surgical technique for the Ross II procedure. Our literature search identified 14 studies that reported results from the Ross II operation. Performed in 103 patients, the overall in-hospital mortality was 7 (6.7%), with a late mortality of 10 (9%). Although further research is needed, current evidence suggests the Ross II operation is a valuable alternative in low-risk young patients where valve durability and the complication rate from other procedures is unsatisfactory and anticoagulation not ideal.

  15. Temporal and Spatial Variability of Ross polynya using Multi-Satellite Observations

    Polynyas are particularly vulnerable to not only local environmental changes, but also global climate changes through air-sea-ice interactions. In order to understand the large scales of its interactions, a temporal and spatial variation of polynyas and, areas of open water in the middle of ice shelf, around the Antarctica were analyzed based on remote sensing measurements. Especially, the polynya in the Ross Sea (Ross polynya) was analyzed, which was the largest on among the all of them around the Antarctica for last decades. Accordingly, the main purpose of this presentation is to (1) evaluate a variability of Ross polynya spatial and temporal characteristics and (2) address relationship between spatial polynya variability and global warming effect. In order to conduct research the observations from the Advanced Microwave Scanning Radiometer-EOS (AMAR-E) were used. The products (SST, wind speed, cloud vapor, atmospheric water vapor and rain rate), including sea ice extent, are from June 2002 to October 2011. Additionally, Gravity Recovery and Climate Experiment (GRACE) data sets were used to estimate mass changes in adjacent ice sheet affected by local atmospheric condition. Based on the nine year's data, research results suggest that Ross polynya normally started to appear around the end of December and persist for about 77.5 days. The extent of Ross polynya in 2011 is the largest and had a tendency to increase year after year. SST in adjacent sea has slightly decreased for the same period (as 0.054◦C yr-1) due to the melting ice and variation of wind, water vapor and rain rate are 0.054 m s-1 yr-1, -0.027 mm yr-1 and 0.001 mm hr-1 yr-1, respectively. Increase land mass in the west-southern Antarctica could be the result of accumulating snow which is made of vapor induced by extended polynya. In addition, we would conduct to evaluate a correlation with characteristics of other global and local components corresponding climate change and understand that how the

  20. Physiochemical controls on phytoplankton distributions in the Ross Sea, Antarctica

    NASA Astrophysics Data System (ADS)

    Liu, Xiao; Smith, Walker O.

    2012-06-01

    The continental shelf of the Ross Sea, Antarctica, is characterized by extreme seasonal and interannual changes in atmospheric and oceanographic processes, which result in distinct temporal patterns in phytoplankton biomass and assemblage composition. However, the environmental forcing of these variations remains uncertain, especially when a series of correlated variables are considered. Hydrological profiles, dissolved nutrients, particulate matter, and phytoplankton pigments were measured in the southern Ross Sea in austral spring and summer during four years (1996-97, 2003-04, 2004-05, and 2005-06), and a series of multivariate analyses were conducted to assess the causative mechanisms in the control of phytoplankton distributions in the Ross Sea. Our results demonstrate that the significant interannual, seasonal and spatial variability that occurs in the southern Ross Sea in hydrographic and chemical properties is highly correlated with the variability in phytoplankton distributions. Although multiple controlling mechanisms were suggested, mixed layer depths did not appear to be a dominant factor regulating phytoplankton biomass or composition; conversely, we found a significant role of water column temperature in structuring phytoplankton assemblage composition in the southern Ross Sea, in that cooler water strongly selects for Phaeocystis antarctica, which is a dominant control of carbon flux to depth, and thus of substantial biogeochemical importance.

    To study the theories and quantification methods of environmental carrying capacity is of significance in reality for directing human beings economic behaviors and harmonizing the relationships between social development and environment. In this paper, the definition of environmental carrying capacity was introduced from the aspects of "capacity", "threshold" and "capability", with the main characteristics of objective and subjective, regional and temporal, and dynamic and adjustable, and its research progress was reviewed. On the basis of these, the quantification methods of environmental carrying capacity, including exponential assessment, carrying rate assessment, system dynamics, and multi-objective optimization, were analyzed, and the research perspectives of environmental carrying capacity were discussed.

    The first projects relating to levels of Cd and Hg on marine biota and sediments from Terra Nova Bay (Ross Sea--Antarctica) and their bioaccumulation and biomagnification in this trophic web have been carried out by research programmes pertaining to the Italian Antarctic Research Program (PNRA) since 1989. Making use of this data, and checking the same metals after 10 years thanks to the samples stored in the BCAA, we have looked for the levels of Cd and Hg in a coastal marine ecosystem of Terra Nova Bay, and have proposed using some organisms to monitor the levels of these two heavy metals in this environment where the Italian Base is located, using the data determinate in this work as background levels. In our work, the amount of Hg and Cd concentrations have been determined in biota from the inner shelf of Terra Nova Bay (Adamussium colbecki, Laternula elliptica, Odontaster validus, Sterechinus neumayeri, Trematomus bernacchii, Iridaea cordata, Phyllophora antarctica, Parborlasia corrugatus), and in two different size fractions of sieved marine sediments (<2000 microm and <63 microm). To widen the distribution of Cd and Hg in this ecosystem we have also investigated the fraction of these metals bound to the labile phase of the marine sediments, and their presence in the particulate matter found in pack-ice cores, recent snow, water column and sea microlayer.

    1990-08-01

    The author outlines a program to confront the massive environmental problems facing our nation and the world today. These are problems that will pose an increasing threat to our national security in the years ahead. Population growth is already pressing supplies of clean water and food in many areas. Deforestation on a vast scale is resulting in the loss of thousands of species of living things-including many species that contain genetic resouces of enormous potential value to agriculture and medicine. Rapidly increasing atmospheric concentrations of gases such as chlorofluorocarbons and halons, if unchecked, will lead to ozone depletion, increasing exposure to cancer-causing ultra-violet radiation. Although there is still a good deal of uncertainty associated with global warming, some reputable scientists have predicted that increasing production of greenhouse gases may ultimately lead to major global environmental changes and massive crop failures, floods and drought-events that could rival a nuclear war in their destructive impact. America must lead the way in marshalling a global response to the problems of environmental degradation, and the defense establishment should play an important role in this effort.

    Public health researchers increasingly turn to qualitative methods either on their own or in combination with quantitative methods. Qualitative methods are especially important to community environmental health research, as they provide a way to produce community narratives that give voice to individuals and characterize the community in a full and complex fashion. This article first traces the legacy of qualitative research in environmental health, then uses a case study of the author's experiences studying the Woburn, Massachusetts, childhood leukemia cluster to provide personal and scholarly insights on qualitative approaches. That material then informs a discussion of important components of qualitative methods in environmental health research, including flexible study design, access, trust, empathy, and personal shifts in the researcher's worldview, bias, and the nature of the researcher's roles. A concluding discussion addresses issues in funding policy and research practices. PMID:14594634

    NASA image acquired January 22, 2011 To view the full image go to: www.flickr.com/photos/gsfc/5397636843 Every southern spring and summer, after the Sun has risen into its 24-hour circuit around the skies of Antarctica, the Ross Sea bursts with life. Floating, microscopic plants, known as phytoplankton, soak up the sunlight and the nutrients stirring in the Southern Ocean and grow into prodigious blooms. Those blooms become a great banquet for krill, fish, penguins, whales, and other marine species who carve out a living in the cool waters of the far south. This true-color image captures such a bloom in the Ross Sea on January 22, 2011, as viewed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Bright greens of plant-life have replaced the deep blues of open ocean water. The Ross Sea is a relatively shallow bay in the Antarctic coastline and due south from New Zealand. As the spring weather thaws the sea ice around Antarctica, areas of open water surrounded by ice—polynyas—open up on the continental shelf. In this open water, sunlight provides the fuel and various current systems provide nutrients from deeper waters to form blooms that can stretch 100 to 200 kilometers (60 to 120 miles). These blooms are among the largest in extent and abundance in the world. Scientists have hypothesized that the Modified Circumpolar Deep Water is the engine behind the blooms, stirring up just the right mix of trace metals and minerals from the deep to sustain plankton growth. This month, researchers aboard the U.S. icebreaking ship Nathaniel B. Palmer are cruising in the Ross Sea in search of the signatures of this current system.

  15. Influence of hydrography on phytoplankton distribution in the Amundsen and Ross Seas, Antarctica

    NASA Astrophysics Data System (ADS)

    Fragoso, Glaucia M.; Smith, Walker O.

    2012-01-01

    The phytoplankton of the Ross Sea have been intensively studied, in contrast to that of the Amundsen Sea. This study focused on understanding the environmental variables that influence the spatial patterns of assemblages during late summer, 2007, and late spring-early summer, 2008 in the Amundsen and Ross Seas. Blooms of the prymnesiophyte Phaeocystis antarctica, and the silicoflagellate Dictyocha speculum occurred in the southwestern to eastern parts of the Ross Sea, respectively, whereas diatoms dominated in southeastern Ross and the Amundsen Sea. Shallow mixed layers supported the growth of diatoms, but were not the only factor required for diatom bloom development. Modified Circumpolar Deep Water intruded into the subsurface waters (< 200 m) in the southwestern Ross Sea during February 2007, and possibly favored the formation of P. antarctica blooms. Photosynthetic quantum yield data suggest that blooms from the southwestern Ross Sea were approaching stress during January 2008, likely due to iron limitation, in contrast to blooms close to the ice edge in the Amundsen Sea, where iron may be more available to the phytoplankton. A detailed comparison between the Amundsen and Ross Seas may allow a greater understanding of the environmental-induced impacts on phytoplankton distribution and regional biogeochemical cycles.

    1994-05-01

    Cleanup and treatment of hazardous wastes incur major operational costs for the U.S. Air Force. Bioremediation can provide a cost-effective alternative to traditional technologies for a wide range of natural organic compounds such as jet fuel. Bioventing and natural attenuation are emerging as treatments of choice in many instances. Synthetic organic chemicals are much more resistant to biodegradation. However, recent advances in biotechnology allow the development of strains able to use nitro- and chloro-substituted organic compounds as their sole source of carbon and energy. Current basic research is focused on expanding the range of synthetic chemicals amenable to biodegradation. At the same time, development of appropriate bioreactors and models for scale up are essential for practical application of the technology.

  2. Environmental health research in Europe: bibliometric analysis.

    This article describes a bibliometric review of the environmental health research literature in Europe for a period of 10 years. The work, within the study SPHERE (Strengthening Public Health Research in Europe) aimed to provide an overview of the extent of published environmental health research in Europe and to assess recent output in this research field and future research direction. Medline was used via the PubMed online service of the US National Library of Medicine. Only original, peer-reviewed research journal articles were retrieved, which were published from mid-1995 to mid-2005 and by authors from the 28 (then) countries in Europe of the European Economic Area plus Switzerland. In the PubMed database, 6329 references were located and were allocated to 11 pre-defined topic areas and 31 subtopic areas. The largest number of articles was in the topic area of work environment and health (2339) followed by environmental exposures (1314) and environmental illnesses (952) and these were the primary foci of 73% of the published articles. There were marked differences between countries in the number of published articles. Ten countries contributed 81% of all publications. It is apparent that economic factors have a major role for research outputs of countries in environmental health. Major advances have been made during recent years in the understanding of associations between health and environment, and of biological, environmental and social mechanisms involved in this association. More emphasis should be placed on investigations of complex environmental health problems such as complex exposures to different pollutants at different levels and their combined health impact in different populations.

    Research conducted during the past year in the climate and atmospheric modeling programs was focused on the development of appropriate atmospheric and upper ocean models, and preliminary applications of these models. Prinicpal models are a one-dimensional radiative-convection model, a three-dimensional global climate model, and an upper ocean model. Principal application is the study of the impact of CO2, aerosols and the solar constant on climate. Also the performance of the International Satellite Cloud Climatology Project cloud detection algorithm was evaluated, concentrating initially on its application to geosynchronous data, with an eventual switch of the developed methodologies to data from polar orbiting satellites. In the process, a number of improvements were made, in particular: an improved technique for tracking small scale day to day variability in clear sky continental temperatures; a number of techniques for the statistical assessment of cloud detection uncertainties due to cloud types which are spatially and temporally invariant; and a method used to detect those cloudy regions which have long term spatial and temporal stability.

    Antarctica offers a good opportunity to investigate planetary-scale pollution and climate change, and provides baseline values for contaminants such as Trace Elements (TEs) and Persistent Organic Pollutants (POPs). Literature data on contaminant levels in the Antarctic environment indicate that long-range atmospheric transport is the primary pathway by which pollutants from surrounding continents are carried to this pristine environment. However, local contamination sources represented by the scientific stations are also not negligible. Climate change and global warming are altering the global budget of anthropogenic contaminants and their monitoring in Antarctica ecosystems is very important to protect the global environment. In this work, eighty specimens of Adamussium colbecki (Smith, 1902), a benthic Antarctic scallop, collected from 1996 to 2009 and stored in the Antarctic Environmental Specimen Bank, were analyzed to quantify TEs and POPs, including polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs) and polycyclic aromatic hydrocarbons (PAHs). Metals concentrations were not affected by anthropogenic contributions, highlighting a natural accumulation with the age of the organism. Similarly, no temporal trend was found for PCNs, PCBs and PAHs. However, specimens collected during the summer 1997-98 showed enhanced concentration levels of PCBs and PAHs that could refer to a local anthropogenic source of contamination.

  20. Ross Ice Shelf airstream driven by polar vortex cyclone

    NASA Astrophysics Data System (ADS)

    Schultz, Colin

    2012-07-01

    The powerful air and ocean currents that flow in and above the Southern Ocean, circling in the Southern Hemisphere's high latitudes, form a barrier to mixing between Antarctica and the rest of the planet. Particularly during the austral winter, strong westerly winds isolate the Antarctic continent from heat, energy, and mass exchange, bolstering the scale of the annual polar ozone depletion and driving the continent's record-breaking low temperatures. Pushing through this wall of high winds, the Ross Ice Shelf airstream (RAS) is responsible for a sizable amount of mass and energy exchange from the Antarctic inland areas to lower latitudes. Sitting due south of New Zealand, the roughly 470,000-square-kilometer Ross Ice Shelf is the continent's largest ice shelf and a hub of activity for Antarctic research. A highly variable lower atmospheric air current, RAS draws air from the inland Antarctic Plateau over the Ross Ice Shelf and past the Ross Sea. Drawing on modeled wind patterns for 2001-2005, Seefeldt and Cassano identify the primary drivers of RAS.

    In August, 1980, the National Oceanic and Atmospheric Administration (NOAA) was given the responsibility, per the Ocean Thermal Energy Conversion Act of 1980 (P.L. 96-320), to establish a legal regime that would foster the commercialization of ocean thermal energy conversion (OTEC) in a manner that protects the marine environment. NOAA developed both an EIS and an environmental effects research plan in accord with the requirements of the Act. These efforts, coupled with an assessment of past OTEC environmental research, highlight the following topics as being of high research priority: direct licensing requirements, and effects on fisheries. Cost-effective and timely research on these topics will be supportive of OTEC commercialization.

    The COOPEUS project was initiated in 2012 bringing together 10 research infrastructures (RIs) in environmental sciences from the EU and US in order to improve the discovery, access, and use of environmental information and data across scientific disciplines and across geographical borders. The COOPEUS mission is to facilitate readily accessible research infrastructure data to advance our understanding of Earth systems through an international community-driven effort, by: Bringing together both user communities and top-down directives to address evolving societal and scientific needs; Removing technical, scientific, cultural and geopolitical barriers for data use; and Coordinating the flow, integrity and preservation of information. A survey of data availability was conducted among the COOPEUS research infrastructures for the purpose of discovering impediments for open international and cross-disciplinary sharing of environmental data. The survey showed that the majority of data offered by the COOPEUS research infrastructures is available via the internet (>90%), but the accessibility to these data differ significantly among research infrastructures; only 45% offer open access on their data, whereas the remaining infrastructures offer restricted access e.g. do not release raw data or sensible data, demand user registration or require permission prior to release of data. These rules and regulations are often installed as a form of standard practice, whereas formal data policies are lacking in 40% of the infrastructures, primarily in the EU. In order to improve this situation COOPEUS has installed a common data-sharing policy, which is agreed upon by all the COOPEUS research infrastructures. To investigate the existing opportunities for improving interoperability among environmental research infrastructures, COOPEUS explored the opportunities with the GEOSS common infrastructure (GCI) by holding a hands-on workshop.

To assist LANL is this effort, Science Applications International Corporation (SAIC) conducted an assessment of technologies and monitoring methods that have been demonstrated or are under development. The focus of this assessment is to: (1) identify existing technologies for hazardous waste treatment and environmental remediation of old waste sites; (2) identify technologies under development and the status of the technology; (3) assess new technologies that need development to provide adequate hazardous waste treatment and remedial action technologies for DOD and DOE sites; and (4) identify hazardous waste and remediation problems for environmental research and development. There are currently numerous research and development activities underway nationwide relating to environmental contaminants and the remediation of waste sites. To perform this effort, SAIC evaluated current technologies and monitoring methods development programs in EPA, DOD, and DOE, as these are the primary agencies through which developmental methods are being demonstrated. This report presents this evaluation and provides recommendations as to pertinent research needs or activities to address waste site contamination problems. The review and assessment have been conducted at a programmatic level; site-specific and contaminant-specific evaluations are being performed by LANL staff as a separate, related activity.

  9. Liquid hydrocarbons probable under Ross Sea

    Thick glacial strata, which have no source-rock potential, cover the Ross Sea. If these strata persist to great depths, then hydrocarbon-generation prospects will be poor. Deeply buried strata within Ross Sea rift-grabens, if like other Gondwana rift-deposits, could have good potential for hydrocarbon generation. Current hydrocarbon assessments of the Ross Sea and adjacent areas must be considered highly speculative because the deeply buried rift(?) strata have not been sampled in situ. The assessment of the Ross Sea relies on geophysical/geologic data, two-stage rift models, and data from formerly nearby Gondwana rift-basins. We conclude that conditions favorable for hydrocarbon generation and entrapment are likely throughout the Ross Sea, and especially in the Victoria Land basin, if adequate source beds exist. -Authors

    The discussions in this fifth workshop were directed to the advances which have been made in the environmental chemistry of plutonium and to the feasibility and worth of developing environmental transport models which might serve as predictive tools for long term behavior and as guides for future research needs. Two plutonium models of the soil/plant pathway were presented for critique and as examples of possible approaches. Reports of the following four panels are presented in this proceedings: model development; marine; terrestrial and freshwater/groundwater.

  11. RESEARCH PAPERS : Palaeomagnetism of the Ross of Mull granite complex, western Scotland: lower Palaeozoic apparent polar wander of the Orthotectonic Caledonides

    NASA Astrophysics Data System (ADS)

    Piper, J. D. A.

    1998-01-01

    The Ross of Mull granite complex was emplaced near the western margin of the Orthotectonic Caledonides of Scotland in early-mid-Silurian times. Anisotropy of magnetic susceptibility reflects the post-tectonic character of the pluton and contrasts with magnetic fabrics in adjoining country rocks which record the regional D3 deformation. Palaeomagnetic study identifies two dominant magnetizations. An `A' component is magnetite-resident with distributed blocking temperatures (100-500°C) and normal polarity (D/I=339/-50°, 30 samples, α95=5.6°, palaeomagnetic pole at 12°E, 1°S, dp/dm=5.0/7.5°) it was probably acquired during initial cooling. A `B' magnetization (unblocking temperatures 500-580°C, D/I=195/+21°, 40 samples, α95=4.3°, palaeomagnetic pole at 339°E, 22°S, dp/dm=2.4/4.5°) is of dual polarity and comparable to magnetizations widely recorded in the Younger Granite Suite of the Scottish Caledonides. It does not correlate with the timing of regional isotopic closure as defined by K/Ar thermochron ages and appears to have been imparted during a regional thermochemical event at low temperatures (~250-150°C) and a late stage of cooling of the orogen (~420-410 Ma). Metamorphic facies in the aureole and adjoining country rocks record examples of both A and B magnetizations, together with a low-blocking-temperature (0-350°C) component acquired during late Palaeozoic/early Mesozoic rifting in the Hebridean Basin. Palaeomagnetic poles from the Orthotectonic Caledonides define a late to post-tectonic magnetization record equivalent to a general east to west apparent polar wander trend of late Ordovician-Lower Devonian age. A short-term reversal of this trend is identified during the earlier part of Silurian times so that mid-late Silurian poles are located in a similar position to late Ordovician poles. The overall path coincides with the contemporaneous record from the Paratectonic Caledonides of England and Wales from c. 455 Ma. It is therefore concluded

  12. Environmental health research and the observer's dilemma.

    Resnik, David B

    2009-08-01

    Environmental health researchers frequently study people in occupational, educational, recreational, or domestic settings who are exposed to hazardous agents. Deciding whether-and how-to inform research subjects about risks they face in their environment can be a challenging task for investigators. Because legal rules and professional guidelines do not cover this topic, investigators must carefully consider their ethical obligations in light of the facts and circumstances. To navigate through this dilemma, investigators should consider the evidence for the risks, the nature of the risks, the usefulness of risk information to the subjects, and the effects on the study and community of informing subjects about risks.

    Abstract Here we present distributional records for Tanaidacea specimens collected during several Antarctic expeditions to the Ross Sea: the Italian PNRA expeditions (“V”, 1989/1990; “XI”, 1995/1996; “XIV”, 1998/1999; “XIX”, 2003/2004; “XXV”, 2009/2010) and the New Zealand historical (New Zealand Oceanographic Institute, NZOI, 1958-1961) and recent (“TAN0402 BIOROSS” voyage, 2004 and “TAN0802 IPY-CAML Oceans Survey 20/20” voyage, 2008) expeditions. Tanaidaceans were obtained from bottom samples collected at depths ranging from 16 to 3543 m by using a variety of sampling gears. On the whole, this contribution reports distributional data for a total of 2953 individuals belonging to 33 genera and 50 species. All vouchers are permanently stored in the Italian National Antarctic Museum collection (MNA), Section of Genoa (Italy) and at the National Institute of Water and Atmospheric Research (NIWA Invertebrate Collection), Wellington (New Zealand).

    Cystic fibrosis (CF) is a rare fatal genetic disease, affecting 70,000 to 100,000 people worldwide [1]. Numerous countries have specific charitable organizations dedicated to CF, with many funding research to find a cure or effective control for the disease. Cystic Fibrosis Canada, the largest charity in Canada dedicated to funding research and care in CF, conducted an environmental scan of these organizations to learn and better understand their research goals and funding process. A set of questions was sent to 25 CF charitable organizations around the world by email. Responses were consolidated to identify common practices and innovative approaches. Among respondents, there were variations in the amount of funds invested in research annually and the number of studies supported. Common themes identified included practicing an open call for research applications, evaluating applications using a peer review process, and placing an increased emphasis on patient engagement. Innovative approaches included funding one larger project; funding a series of sub-projects on a common theme; partially funding a research project; and, indefinitely funding part of a researcher's salary. Among CF charitable organizations, there are numerous approaches to research funding. Both similarities and differences were noted between these organizations, all of which share the common goal of working towards improving quality of life and survival for people with CF.

    This paper discusses ways to reconcile the United Nations Millennium Development Goals with environmental sustainability at the national and international levels. The authors argue that development and better use of sustainability relevant knowledge is key, and that this requires capacity building globally, and especially in the less developed regions of the world. Also essential is stronger integration of high-quality knowledge creation and technology--and policy--development, including, importantly, the creation of centers of excellence in developing regions which effectively use and produce applications-directed high quality research and bring it to bear on decision making and practices related to environmental change and sustainable management of natural resources. The authors argue that Southern centers of excellence are a necessary first step for bottom-up societal transformation towards sustainability, and that such centers must help design innovative ways to assess and place value on ecosystem services.

    The Antarctic Ross Sea is one of the key regions for polar research activities. Research stations from several countries located at the coast are the base for inland expeditions. Even in the austral summer, the Ross Sea is party covered with drifting ice fields; this requires an icebreaker for all marine explorations. Therefore, large geophysical surveys in the Ross Sea are difficult. But the area is of special interest for seismologists: The Terror Rift in the western Ross Sea is a prominent neotectonic structure of the West Antarctic Rift System (WARS). It is located near the coast in the Victoria Land Basin and extends parallel to the Transantarctic Mountains. The rifting processes and the accompanying active onshore volcanism lead to increased seismicity in the region. The annual waxing and waning of the sea-ice and the dynamics of the large Ross Ice Shelf and nearby glaciers generate additional seismic signals. Investigation on seismological activities associated with the WARS and the cryogenic signals simultaneously would give us an unprecedented opportunity to have a better understanding of the Evolution of the WARS (EWARS) and the rapid change in the cryospheric environment nearby. The Korea Polar Research Institute (KOPRI) and the Alfred-Wegener-Institut (AWI) have conducted a pilot study off the Korean Jang Bogo research station in the Terra Nova Bay by developing a collaborative research program (EWARS) since 2011 to explore seismicity and seismic noise in this region. Four broadband ocean-bottom seismometers (OBS) from the German DEPAS pool were deployed in January 2012 with the Korean research icebreaker RV Araon. Three instruments could successfully be recovered after 13 months, the fourth OBS was not accessible due to local sea-ice coverage. We have successfully completed a second recovery operation in January 2014. All stations recorded data of good quality, one station stopped after 8 months due to a recorder error. The OBS recovered in 2014

    The objective of the Environmental Research Program is to enhance the understanding of, and mitigate the effects of pollutants on health, ecological systems, global and regional climate, and air quality. The program is multidisciplinary and includes fundamental research and development in efficient and environmentally benign combustion, pollutant abatement and destruction, and novel methods of detection and analysis of criteria and noncriteria pollutants. This diverse group conducts investigations in combustion, atmospheric and marine processes, flue-gas chemistry, and ecological systems. Combustion chemistry research emphasizes modeling at microscopic and macroscopic scales. At the microscopic scale, functional sensitivity analysis is used to explore the nature of the potential-to-dynamics relationships for reacting systems. Rate coefficients are estimated using quantum dynamics and path integral approaches. At the macroscopic level, combustion processes are modelled using chemical mechanisms at the appropriate level of detail dictated by the requirements of predicting particular aspects of combustion behavior. Parallel computing has facilitated the efforts to use detailed chemistry in models of turbulent reacting flow to predict minor species concentrations.

    Ahmed, E; Holmström, S J M

    2014-01-01

    Siderophores are organic compounds with low molecular masses that are produced by microorganisms and plants growing under low iron conditions. The primary function of these compounds is to chelate the ferric iron [Fe(III)] from different terrestrial and aquatic habitats and thereby make it available for microbial and plant cells. Siderophores have received much attention in recent years because of their potential roles and applications in various areas of environmental research. Their significance in these applications is because siderophores have the ability to bind a variety of metals in addition to iron, and they have a wide range of chemical structures and specific properties. For instance, siderophores function as biocontrols, biosensors, and bioremediation and chelation agents, in addition to their important role in weathering soil minerals and enhancing plant growth. The aim of this literature review is to outline and discuss the important roles and functions of siderophores in different environmental habitats and emphasize the significant roles that these small organic molecules could play in applied environmental processes.

The student body at the college generally reflects that of the service district. The college strives to recruit students from all segments of the population so there is representation among all ethnic and economic groups. The college strives to serve students and the community by offering educational opportunities that meet the needs of both elements and which will lead to gainful employment. Instruction is also offered to meets needs for retraining, upgrades, and personal enlightenment. The college started a hazardous materials management program in the fall of 1991 which has since been renamed environmental management. The purpose of this program is to prepare students for environmental careers, to provide required training such as OSHA HAZWOPER and refresher courses, and to provide educational opportunities that would make the public more environmentally aware. The program content needs to be studied to ensure we`re meeting the needs of the students and the business community. There had not been a significant opportunity to conduct this research.

    Ronald Ross and George Macdonald are credited with developing a mathematical model of mosquito-borne pathogen transmission. A systematic historical review suggests that several mathematicians and scientists contributed to development of the Ross-Macdonald model over a period of 70 years. Ross developed two different mathematical models, Macdonald a third, and various "Ross-Macdonald" mathematical models exist. Ross-Macdonald models are best defined by a consensus set of assumptions. The mathematical model is just one part of a theory for the dynamics and control of mosquito-transmitted pathogens that also includes epidemiological and entomological concepts and metrics for measuring transmission. All the basic elements of the theory had fallen into place by the end of the Global Malaria Eradication Programme (GMEP, 1955-1969) with the concept of vectorial capacity, methods for measuring key components of transmission by mosquitoes, and a quantitative theory of vector control. The Ross-Macdonald theory has since played a central role in development of research on mosquito-borne pathogen transmission and the development of strategies for mosquito-borne disease prevention.

    Bergamasco, A.; Defendi, V.; Spezie, G.; Budillon, G.; Carniel, S.

    In the framework of the CLIMA Project of the Italian National Program for Research in Antarctica, three different experimental data sets were acquired along the continental shelf break; two of them (in 1997 and 2001) close to Cape Adare, the 1998 one in the middle of the Ross Sea (i.e. 75 S, 177 W). The investigations were chosen in order to explore the downslope flow of the bottom waters produced in the Ross Sea, namely the High Salinity Shelf Water (HSSW, the densest water mass of the southern ocean coming from its formation site in the polynya region in Terra Nova bay), and the Ice Shelf Water (ISW, originated below the Ross Ice Shelf and outflowing northward). Both bottom waters spill over the shelf edge and mix with the Circumpolar Deep Water (CDW) contributing to the formation of the Antarctic Bottom Waters (AABW). Interpreting temperature, salinity and density maps in terms of cascading processes, both HSSW and ISW overflows are evidenced during, respectively, 1997 and 1998. During the 2001 acquisition there is no presence of HSSW along the shelf break, nevertheless distribution captures the evidence of a downslope flow process.

    Background: Many pregnancy and birth cohort studies investigate the health effects of early-life environmental contaminant exposure. An overview of existing studies and their data is needed to improve collaboration, harmonization, and future project planning. Objectives: Our goal was to create a comprehensive overview of European birth cohorts with environmental exposure data. Methods: Birth cohort studies were included if they a) collected data on at least one environmental exposure, b) started enrollment during pregnancy or at birth, c) included at least one follow-up point after birth, d) included at least 200 mother–child pairs, and e) were based in a European country. A questionnaire collected information on basic protocol details and exposure and health outcome assessments, including specific contaminants, methods and samples, timing, and number of subjects. A full inventory can be searched on www.birthcohortsenrieco.net. Results: Questionnaires were completed by 37 cohort studies of > 350,000 mother–child pairs in 19 European countries. Only three cohorts did not participate. All cohorts collected biological specimens of children or parents. Many cohorts collected information on passive smoking (n = 36), maternal occupation (n = 33), outdoor air pollution (n = 27), and allergens/biological organisms (n = 27). Fewer cohorts (n = 12–19) collected information on water contamination, ionizing or nonionizing radiation exposures, noise, metals, persistent organic pollutants, or other pollutants. All cohorts have information on birth outcomes; nearly all on asthma, allergies, childhood growth and obesity; and 26 collected information on child neurodevelopment. Conclusion: Combining forces in this field will yield more efficient and conclusive studies and ultimately improve causal inference. This impressive resource of existing birth cohort data could form the basis for longer-term and worldwide coordination of research on environment and child health. PMID

    (1) To examine the feasibility to link climate data with monthly incidence of Ross River virus (RRv). (2) To assess the impact of climate variability on the RRv transmission. An ecological time series analysis was performed on the data collected between 1985 to 1996 in Queensland, Australia. Information on the notified RRv cases was obtained from the Queensland Department of Health. Climate and population data were supplied by the Australian Bureau of Meteorology and the Australian Bureau of Statistics, respectively. Spearman's rank correlation analyses were performed to examine the relation between climate variability and the monthly incidence of notified RRv infections. The autoregressive integrated moving average (ARIMA) model was used to perform a time series analysis. As maximum and minimum temperatures were highly correlated with each other (r(s)=0.75), two separate models were developed. For the eight major cities in Queensland, the climate-RRv correlation coefficients were in the range of 0.12 to 0.52 for maximum and minimum temperatures, -0.10 to 0.46 for rainfall, and 0.11 to 0.52 for relative humidity and high tide. For the whole State, rainfall (partial regression coefficient: 0.017 (95% confidence intervals 0.009 to 0.025) in Model I and 0.018 (0.010 to 0.026) in Model II), and high tidal level (0.030 (0.006 to 0.054) in Model I and 0.029 (0.005 to 0.053) in Model II) seemed to have played significant parts in the transmission of RRv in Queensland. Maximum temperature was also marginally significantly associated with the incidence of RRv infection. Rainfall, temperature, and tidal levels may be important environmental determinants in the transmission cycles of RRv disease.

    The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the U.S. Department of Energy (DOE) Office of Science (SC), the single largest supporter of basic research in the physical sciences in the United States. In support of SC programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet be a highly successful enabler of scientific discovery for over 25 years. In November 2012, ESnet and the Office of Biological and Environmental Research (BER) of the DOE SC organized a review to characterize the networking requirements of the programs funded by the BER program office. Several key findings resulted from the review. Among them: 1) The scale of data sets available to science collaborations continues to increase exponentially. This has broad impact, both on the network and on the computational and storage systems connected to the network. 2) Many science collaborations require assistance to cope with the systems and network engineering challenges inherent in managing the rapid growth in data scale. 3) Several science domains operate distributed facilities that rely on high-performance networking for success. Key examples illustrated in this report include the Earth System Grid Federation (ESGF) and the Systems Biology Knowledgebase (KBase). This report expands on these points, and addresses others as well. The report contains a findings section as well as the text of the case studies discussed at the review.

    Baker, J.

    1971-01-01

    It is shown that aspheric deformations of the first and fourth elements of the four element Ross objective can be introduced to permit one to obtain improved color corrections for astrometric purposes. The usual monochromatic aberrations are as well corrected as for the standard Ross lens. In addition, one can eliminate or reduce additional aberrations, such as secondary spectrum, chromatic spherical aberration, chromatic coma and chromatic distortion. The resulting objectives are suitable for use as intermediate and long focus astrometric objectives covering large angle fields.

    Wall, Judy D.

    2003-11-19

    The main objective of the Gordon Research Conference on Applied and Environmental Microbiology was to present and discuss new, fundamental research findings on microorganisms, their activities in the environment, their ecosystem-level effects, and their environmental or commercial applications. To accomplish this goal, knowledge of microbial diversity, interactions and population dynamics was required. The genomic basis of microbial processes, the cycling of naturally occurring and hazardous substances, and methodologies to assess the functional relationships of microorganisms in their habitats were essential for understanding the ecological consequences of microbial activities and the formulation of generalizing principles. In the last decade, molecular technology has revealed that microbial diversity is far more extensive than the limited view obtained from culturing procedures. Great advances in environmental microbiology have resulted from the development and application of molecular approaches to ecology and molecular evolution. A further surprise resulting from the application of these new tools is the blurring of the distinction between pathogenic traits versus those considered non-pathogenic. This year's conference addressed the issues of biodiversity, its development, and the impact of stress on gene selection and expression. In addition microbial metabolic versatility with toxins such as heavy metals, antibiotics, and organic pollutants were discussed. The nine session topics were (1) biodiversity and the bacterial species, (2) mechanisms of biodiversification, (3) biofilms in health and environment, (4) a genomic view of microbial response to stress, (5) microbial use of toxic metals, (6) microbial mineral formation and dissolution, (7) power and limitations of antimicrobials, (8) biodegradation of organic pollutants, and (9) astrobiology. The Conference had an international profile: the Conference Vice-Chair, Dr. Gerard Muyzer, was from The Nether lands

    We have developed state-of-the-art nanomaterials such as nanofibers, nanotubes, nanoparticles, nanocatalysts and nanostructures for clean energy, environmental and biomedical research. Energy can neither be created nor be destroyed, but it can be converted from one form to another. Based on this principle, chemical energy such as hydrogen has been produced from water electrolysis at a much lower voltage using RuO{sub 2} nanoparticles on the Si wafer substrate. Once the hydrogen is produced from the clean sources such as solar energy and water, it has to be stored by physisorption or chemisorption processes on to the solid state systems. For the successful physical adsorption of hydrogen molecule, we have developed novel polyaniline nanostructures via chemical templating and electrospinning routes. Chemical or complex hydrides involving nano MgH{sub 2} and transition metal nanocatalysts have been synthesized to tailor both the thermodynamics and kinetics of hydrogen (chemi) sorption respectively. Utilization of solar energy (UV-Vis) and a coupling of novel semiconductor oxide nanoparticles have been recently demonstrated with enhancement in photo-oxidation and/or photo-reduction processes for the water/air detoxification and sustainable liquid fuel production respectively. Magnetic nanoparticles such as ZnFe{sub 2}O{sub 4} have been synthesized and optimized for biomedical applications such as targeted drug delivery and tumor diagnostic sensing (MRI)

    2014-01-01

    Objectives Rapid increase in engineered nanoparticles (ENPs) in many goods has raised significant concern about their environmental safety. Proper methodologies are therefore needed to conduct toxicity and exposure assessment of nanoparticles in the environment. This study reviews several analytical techniques for nanoparticles and summarizes their principles, advantages and disadvantages, reviews the state of the art, and offers the perspectives of nanometrology in relation to ENP studies. Methods Nanometrology is divided into five techniques with regard to the instrumental principle: microscopy, light scattering, spectroscopy, separation, and single particle inductively coupled plasma-mass spectrometry. Results Each analytical method has its own drawbacks, such as detection limit, ability to quantify or qualify ENPs, and matrix effects. More than two different analytical methods should be used to better characterize ENPs. Conclusions In characterizing ENPs, the researchers should understand the nanometrology and its demerits, as well as its merits, to properly interpret their experimental results. Challenges lie in the nanometrology and pretreatment of ENPs from various matrices; in the extraction without dissolution or aggregation, and concentration of ENPs to satisfy the instrumental detection limit.

    The launch of volume 8 of Environmental Research Letters (ERL) comes at a critical time in terms of innovations and exciting areas of science, but particularly in the areas linking environmental research and action. The most recent climate change Conference of the Parties meeting (COP), in Doha in December 2012, has now come and gone. As has been dissected in the press, very little was accomplished. Some will see this as a failure, as I do, and others will reasonably enough note that this meeting, the 18th such COP was1 never intended to be a milestone moment. The current plan, in fact, is for a 'post-Kyoto' international climate agreement to be adopted only at the COP20 summit in December 2015. As we lead up to COP20, and potentially other regional or national approaches to climate protection, innovations in science, innovations in policy tools, and political commitment must come together. The science of climate change only continues to get clearer and clearer, and bleaker [1]. Later this year the IPCC will release its Fifth Assessment Report, AR5. The draft versions are out for review now. ERL has published a number of papers on climate change science, mitigation and adaptation, but one area where the world needs a particular focus is on the nexus of science and action. A summary of the Intergovernmental Panel on Climate Change's findings from the first assessment report (FAR; 1990) to the latest report is presented in figure 1. This graphic is specifically not about the scientific record alone. What is most important about this figure is the juxtaposition of the language of science and the language of ... language.

    crucial role in the formation of oceanic deep water responsible for ocean/continental shelf exchange of organic carbon, suspended material and dissolved gases around Antarctica. In this context, this work presents the analysis of the 1997, 2001 and 2003 high-resolution surveys carried out in the western Ross Sea near Cape Adare, where the HSSW flows down the continental slope. The second study area was investigated during the 1998 survey of the Italian National Programme for Antarctic Research of the CLIMA Project, in order to follow the ISW overflow path at the shelf break in the central Ross Sea. A 3D primitive equation model was also implemented as a first step in the construction of a high-resolution process study model to explore the dynamical constraints involved in the downslope motion.

  6. Climatological aspects of mesoscale cyclogenesis over the Ross Sea and Ross Ice shelf regions of Antarctica

    SciTech Connect

    Carrasco, J.F.; Bromwich, D.H.

    1994-11-01

    A one-year (1988) statistical study of mesoscale cyclogenesis near Terra Nova Bay and Byrd Glacier, Antarctica, was conducted using high-resolution digital satellite imagery and automatic weather station data. Results indicate that on average two (one) mesoscale cyclones form near Terra Nova Bay (Byrd Glacier) each week, confirming these two locations as mesoscale cyclogeneis areas. The maximum (minimum) weekly frequency of mesoscale cyclones occurred during the summer (winter). The satellite survey of mesoscale vortices was extended over the Ross Sea and Ross Ice Shelf. Results suggest southern Marie Byrd Land as another area of mesoscale cyclone formation. Also, frequent mesoscale cyclonic activity was noted over the Ross Sea and Ross Ice Shelf, where, on average, six and three mesoscale vortices were observed each week, respectively, with maximum (minimum) frequency during summer (winter) in both regions. The majority (70-80%) of the vortices were of comma-cloud type and were shallow. Only around 10% of the vortices near Terra Nova Bay and Byrd Glacier were classified as deep vortices, while over the Ross Sea and Ross Ice Shelf around 20% were found to be deep. The average large-scale pattern associated with cyclogenesis days near Terra Nova Bay suggests a slight decrease in the sea level pressure and 500-hPa geopotential height to the northwest of this area with respect to the annual average. This may be an indication of the average position of synoptic-scale cyclones entering the Ross Sea region. Comparison with a similar study but for 1984-85 shows that the overall mesoscale cyclogenesis activity was similar during the three years, but 1985 was found to be the year with greater occurrence of {open_quotes}significant{close_quotes} mesoscales cyclones. The large-scale pattern indicates that this greater activity is related to a deeper circumpolar trough and 500-hPa polar vortex for 1985 in comparison to 1984 and 1988. 64 refs., 13 figs., 5 tabs.

  1. Randomized controlled trials in environmental health research: ethical issues.

    PubMed

    Resnik, David B

    2008-01-01

    Randomized controlled trials (RCTs) are becoming increasingly common in environmental health research. Like all studies involving human subjects, environmental health RCTs raise many ethical challenges, ranging from obtaining informed consent to minimizing risks to protecting privacy and confidentiality. One of the most important issues raised by these studies is whether it is ethical to withhold effective environmental health interventions from research subjects in order to satisfy scientific objectives. Although environmental health investigators usually do not have professional obligations to provide medical care to research subjects, they have ethical obligations to avoid exploiting them. Withholding interventions from research subjects can be ethical, provided that it does not lead to exploitation of individuals or groups. To avoid exploiting individuals or groups, investigators should ensure that research subjects and study populations receive a fair share of the benefits of research.

  2. European Community research on environmental mutagenesis and carcinogenesis.

    PubMed Central

    Sors, A I

    1993-01-01

    Within the 12 Member States of the European Community (EC), environmental policy is now formulated primarily at Community level. As a result, the EC has important regulatory responsibilities for the protection of workers, consumers, and the general public from risks that may arise from environmental chemicals, foremost among them potential carcinogens and mutagens. An important part of EC environmental research and development is intended to provide a scientific basis for these regulations as well as increasing understanding of the basic mechanisms involved in environmental carcinogenesis and mutagenesis. This paper contains a brief introduction to EC environment policy and research, followed by an overview of EC chemicals control activities that are of particular relevance to the research and development program. Community-level research on environmental mutagenesis and carcinogenesis is then reviewed in some detail, including the achievements of recent projects, the scientific content of the current program, and perspectives for the future.

    Phenolic compounds are semi-volatile organic compounds produced during biomass burning and lignin degradation in water. In atmospheric and paleoclimatic ice cores studies, these compounds are used as biomarkers of wood combustion and supply information on the type of combusted biomass. Phenolic compounds are therefore indicators of paleoclimatic interest. Recent studies of Antarctic aerosols highlighted that phenolic compounds in Antarctica are not exclusively attributable to biomass burning but also derive from marine sources. In order to study the marine contribution to aerosols we developed an analytical method to determine the concentration of vanillic acid, vanillin, p-coumaric acid, syringic acid, isovanillic acid, homovanillic acid, syringaldehyde, acetosyringone and acetovanillone present in dissolved and particle phases in Sea Ross waters using HPLC-MS/MS. The analytical method was validated and used to quantify phenolic compounds in 28 sea water samples collected during a 2012 Ross Sea R/V cruise. The observed compounds were vanillic acid, vanillin, acetovanillone and p-coumaric acid with concentrations in the ng/L range. Higher concentrations of analytes were present in the dissolved phase than in the particle phase. Sample concentrations were greatest in the coastal, surficial and less saline Ross Sea waters near Victoria Land.

    We have collected year-round nanoclimate data for the cryptoendolithic microbial habitat in sandstones of the Ross desert, Antarctica, obtained with an Argos satellite data system. Data for two sites in the McMurdo Dry Valleys are available: Linnaeus Terrace, January 1985 to June 1988, and Battleship Promontory, 1986-1987. The focus of this research is ecological, and hence year-round environmental data have been obtained for the ambient environment as well as for conditions within the rock. Using data from the summer, we compare the conditions inside the rock to the outside weather. This demonstrates how the rock provides a shelter for the endolithic microbial community. The most important property of the rock is that it absorbs the summer sunlight, thereby warming up to temperatures above freezing. This warming allows snowmelt to seep into the rock, and the moisture level in the rocks can remain high for weeks against loss to the dry environment.

    PubMed

    Obokata, Reiko; Veronis, Luisa; McLeman, Robert

    2014-01-01

    This paper presents the findings of a systematic review of scholarly publications that report empirical findings from studies of environmentally-related international migration. There exists a small, but growing accumulation of empirical studies that consider environmentally-linked migration that spans international borders. These studies provide useful evidence for scholars and policymakers in understanding how environmental factors interact with political, economic and social factors to influence migration behavior and outcomes that are specific to international movements of people, in highlighting promising future research directions, and in raising important considerations for international policymaking. Our review identifies countries of migrant origin and destination that have so far been the subject of empirical research, the environmental factors believed to have influenced these migrations, the interactions of environmental and non-environmental factors as well as the role of context in influencing migration behavior, and the types of methods used by researchers. In reporting our findings, we identify the strengths and challenges associated with the main empirical approaches, highlight significant gaps and future opportunities for empirical work, and contribute to advancing understanding of environmental influences on international migration more generally. Specifically, we propose an exploratory framework to take into account the role of context in shaping environmental migration across borders, including the dynamic and complex interactions between environmental and non-environmental factors at a range of scales.

  17. Directions for environmentally biodegradable polymer research

    SciTech Connect

    Swift, G. )

    1993-03-01

    A major factor promoting interest in biodegradable polymers is the growing concern raised by the recalcitrance and unknown environmental fate of many of the currently used synthetic polymers. These polymers include both water-soluble and water-insoluble types. The former are generally specialty polymers with functional groups that effect water solubility such as carboxyl, hydroxyl, amido, etc.; the latter are usually nonfunctional polymers commonly referred to as commodity plastics. Both types of polymers are widely used in many applications. Water-soluble polymers are used, for example, in cosmetics, water treatment, dispersants, thickeners, detergents, and superabsorbents, and they include poly(acrylic acid), polyacrylamide, poly(vinyl alcohol), and poly(ethylene glycol). Plastics are used in packaging, disposable diaper backing, fishing nets, and agricultural film; they include polymers such as polyethylene, polypropylene, polystyrene, poly(vinyl chloride), poly(ethylene terephthalate), and Nylon 6.6. In this Account, the author presents a personal perspective on definitions and test protocols for biodegradable polymers as well as how they will influence the future direction and developments in the field. However, before doing so he digresses briefly to present a commentary on the role of biodegradable polymers in environmental waste management. This should be useful for those readers unfamiliar with the subject, and it will set the stage for the rest of the discussion. 36 refs., 3 figs.

    2016-01-01

    Environmental justice (EJ) research seeks to document and redress the disproportionate environmental burdens and benefits associated with social inequalities. Although its initial focus was on disparities in exposure to anthropogenic pollution, the scope of EJ research has expanded. In the context of intensifying social inequalities and environmental problems, there is a need to further strengthen the EJ research framework and diversify its application. This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) incorporates 19 articles that broaden EJ research by considering emerging topics such as energy, food, drinking water, flooding, sustainability, and gender dynamics, including issues in Canada, the UK, and Eastern Europe. Additionally, the articles contribute to three research themes: (1) documenting connections between unjust environmental exposures and health impacts by examining unsafe infrastructure, substance use, and children’s obesity and academic performance; (2) promoting and achieving EJ by implementing interventions to improve environmental knowledge and health, identifying avenues for sustainable community change, and incorporating EJ metrics in government programs; and (3) clarifying stakeholder perceptions of EJ issues to extend research beyond the documentation of unjust conditions and processes. Collectively, the articles highlight potentially compounding injustices and an array of approaches being employed to achieve EJ. PMID:27809294

Although its initial focus was on disparities in exposure to anthropogenic pollution, the scope of EJ research has expanded. In the context of intensifying social inequalities and environmental problems, there is a need to further strengthen the EJ research framework and diversify its application. This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) incorporates 19 articles that broaden EJ research by considering emerging topics such as energy, food, drinking water, flooding, sustainability, and gender dynamics, including issues in Canada, the UK, and Eastern Europe. Additionally, the articles contribute to three research themes: (1) documenting connections between unjust environmental exposures and health impacts by examining unsafe infrastructure, substance use, and children's obesity and academic performance; (2) promoting and achieving EJ by implementing interventions to improve environmental knowledge and health, identifying avenues for sustainable community change, and incorporating EJ metrics in government programs; and (3) clarifying stakeholder perceptions of EJ issues to extend research beyond the documentation of unjust conditions and processes. Collectively, the articles highlight potentially compounding injustices and an array of approaches being employed to achieve EJ.

    The principal themes for the Biomedical Research and the Environment Conference Committee on Environmental Economics in Biomedical Research include the following: healthcare delivery companies and biomedical research organizations, both nonprofit and for-profit, need to improve their environmental performance; suppliers of healthcare products will be called upon to support this need; and improving the environmental profile of healthcare products begins in research and development (R&D). The committee report begins with requirements from regulatory authorities (e.g., U.S. Environmental Protection Agency [EPA], the U.S. Food and Drug Administration), and the healthcare delivery sector). The 1998 American Hospital Association and EPA Memorandum of Understanding to reduce solid waste and mercury from healthcare facilities is emblematic of these requirements. The dominant message from the requirements discussion is to ensure that R&D organizations do not ignore customer, environmental, and regulatory requirements in the early stages of product development. Several representatives from healthcare products manufacturers presented their companies' approaches to meeting these requirements. They reported on efforts to ensure that their R&D processes are sensitive to the environmental consequences from manufacturing, distributing, using, and disposing of healthcare products. These reports describe representatives' awareness of requirements and the unique approaches their R&D organizations have taken to meet these requirements. All representatives reported that their R&D organizations have embraced environmental product design because it avoids the potential of returning products to R&D to improve the environmental profile. Additionally, several reports detailed cost savings, sustainability benefits, and improvements in environmental manufacturing or redesign, and increased customer satisfaction. Many companies in healthcare delivery are working to improve environmental

  16. Coastal-change and glaciological map of the Ross Island area, Antarctica

    Ferrigno, Jane G.; Foley, Kevin M.; Swithinbank, Charles; Williams, Richard S.

    2010-01-01

    Reduction in the area and volume of Earth?s two polar ice sheets is intricately linked to changes in global climate and to the resulting rise in sea level. Measurement of changes in area and mass balance of the Antarctic ice sheet was given a very high priority in recommendations by the Polar Research Board of the National Research Council. On the basis of these recommendations, the U.S. Geological Survey used its archive of satellite images to document changes in the cryospheric coastline of Antarctica and analyze the glaciological features of the coastal regions. The Ross Island area map is bounded by long 141? E. and 175? E. and by lat 76? S. and 81? S. The map covers the part of southern Victoria Land that includes the northwestern Ross Ice Shelf, the McMurdo Ice Shelf, part of the polar plateau and Transantarctic Mountains, the McMurdo Dry Valleys, northernmost Shackleton Coast, Hillary Coast, the southern part of Scott Coast, and Ross Island. Little noticeable change has occurred in the ice fronts on the map, so the focus is on glaciological features. In the western part of the map area, the polar plateau of East Antarctica, once thought to be a featureless region, has subtle wavelike surface forms (megadunes) and flow traces of glaciers that originate far inland and extend to the coast or into the Ross Ice Shelf. There are numerous outlet glaciers. Glaciers drain into the McMurdo Dry Valleys, through the Transantarctic Mountains into the Ross Sea, or into the Ross Ice Shelf. Byrd Glacier is the largest. West of the Transantarctic Mountains are areas of blue ice, readily identifiable on Landsat images, that have been determined to be prime areas for finding meteorites. Three subglacial lakes have been identified in the map area. Because McMurdo Station, the main U.S. scientific research station in Antarctica, is located on Ross Island in the map area, many of these and other features in the area have been studied extensively.

  17. Focus on environmental justice: new directions in international research

    2017-03-01

    More than three decades since the emergence of the environmental justice (EJ) movement in the U.S., environmental injustices continue to unfold across the world to include new narratives of air and water pollution, as well as new forms of injustices associated with climate change, energy use, natural disasters, urban greenspaces, and public policies that adversely affect socially disadvantaged communities and future generations. This focus issue of Environmental Research Letters provides an interdisciplinary forum for conceptual, methodological, and empirical scholarship on EJ activism, research, and policy that highlights the continuing salience of an EJ perspective to understanding nature-society linkages. The 16 letters published in this focus issue address a variety of environmental issues and social injustices in multiple countries across the world, and advance EJ research by: (1) demonstrating how environmental injustice emerges through particular policies and political processes; (2) exploring environmental injustices associated with industrialization and industrial pollution; and (3) documenting unjust exposure to various environmental hazards in specific urban landscapes. As the discourse of EJ continues to evolve both topically and geographically, we hope that this focus issue will help establish research agendas for the next generation of EJ scholarship on distributive, procedural, participatory, and other forms of injustices, as well as their interrelationships.

    Abstract The scale and magnitude of complex and pressing environmental issues lend urgency to the need for integrative and reproducible analysis and synthesis, facilitated by data-intensive research approaches. However, the recent pace of technological change has been such that appropriate skills to accomplish data-intensive research are lacking among environmental scientists, who more than ever need greater access to training and mentorship in computational skills. Here, we provide a roadmap for raising data competencies of current and next-generation environmental researchers by describing the concepts and skills needed for effectively engaging with the heterogeneous, distributed, and rapidly growing volumes of available data. We articulate five key skills: (1) data management and processing, (2) analysis, (3) software skills for science, (4) visualization, and (5) communication methods for collaboration and dissemination. We provide an overview of the current suite of training initiatives available to environmental scientists and models for closing the skill-transfer gap. PMID:28584342

  14. The ocean tide in the southern Ross Sea

    NASA Astrophysics Data System (ADS)

    Williams, Richard T.; Robinson, Edwin S.

    1980-11-01

    A survey of the ocean tide in the southern Ross Sea was done by measuring tidal variations of gravity at nine locations on the floating Ross Ice Shelf. Tidal water level fluctuations were calculated from recordings between 29 days and 58 days long of the periodic variation in gravity on the ice shelf surface that is caused by tidal changes in elevation and water mass. Conventional tide gauge measurements from McMurdo Sound were included in the survey. The data indicate that the Ross Sea tide is principally diurnal. Along the northern margin of the Ross Ice Shelf the tropic (diurnal spring) tidal range is between 1 m and ?; m. The range increases to more than 2 m in the southernmost part of the Ross Sea. It is more than 3 times larger than the equatorial (diurnal neap) tidal range. Amplitudes of the principal diurnal constituents K1 P1 and O1 are apparently magnified by a condition of diurnal resonance in the Ross Sea. This would be expected because wavelengths of the diurnal harmonic constituents are approximately 4 times the length of the Ross Sea in the direction of propagation. The diurnal constituent amplitudes also appear to vary proportionally with the fourth root of the water depth as predicted from the theory of long wave propagation in a canal. Semidiurnal constituents M2, S2, and N2 have small amplitudes and appear to progress clockwise around amphidromes located beneath the northwestern part of the Ross Ice Shelf.

    We examined 5 different ethical concerns about the Children's Environmental Exposure Research Study and make some recommendations for future studies of exposure to hazardous environmental agents in the home. Researchers should seek community consultation and participation; make participants aware of all the risks associated with the research, including hazards discovered in the home and uncertainties about the risks of agents under investigation; and take steps to ensure that their studies will not have unfair representation of the poor or people of color. Researchers should also avoid even the appearance of a financial conflict of interest in studies that are likely to be controversial and make it clear to all parties that studies will not intentionally expose subjects to hazardous environmental agents.

  18. Relationships in Areal Variability: The Ross Sea Polynya and Ice

    NASA Astrophysics Data System (ADS)

    Ward, Jason Michael

    General increases in Antarctic sea ice coverage occur primarily in the Ross Sea. This study investigates the Ross Sea Polynya's relationship with the Ross Sea ice areal coverage. A unique, relatively long term Ross Sea Polynya area dataset was created through the application of the Polynya Signature Simulation Method (PSSM) onto Special Sensor Microwave Imager (SSM/I) data inputs. Bivariate regression analyses were used to determine the relationships, at the 95% confidence level, between Ross Sea Polynya and ice areal trends, annual seasonalities, and anomalies at the full temporal scale as well as the monthly level. Polynya and sea ice have significant positive relationships in the late austral summer and early spring (February to March), and a significant negative relationship in the late austral winter (August). The areal anomalies only had a significant relationship in February, while the trends were not correlated at any time.

    James Ross Island captured by NASA photographer James Ross(no relation), from NASA's DC-8 aircraft during an AirSAR 2004 mission over the Antarctic Peninsula. James Ross Island, named for 19th century British polar explorer Sir James Clark Ross, is located at the northern tip of the Antarctic Peninsula. The island is about 1500 m high and 40-60 km wide. In recent decades, the area has experienced significant atmospheric warming (about 2 degrees C since 1950), which has triggered a vast and spectacular retreat of its floating ice shelves, glacier reduction, a decrease in permanent snow cover and a lengthening of the melt season. AirSAR 2004 is a three-week expedition in Central and South America by an international team of scientists that is using an all-weather imaging tool, called the Airborne Synthetic Aperture Radar (AirSAR), located onboard NASA's DC-8 airborne laboratory. Scientists from many parts of the world are combining ground research with NASA's AirSAR technology to improve and expand on the quality of research they are able to conduct. These photos are from the DC-8 aircraft while flying an AirSAR mission over Antarctica. The Antarctic Peninsula is more similar to Alaska and Patagonia than to the rest of the Antarctic continent. It is drained by fast glaciers, receives abundant precipitation, and melts significantly in the summer months. This region is being studied by NASA using a DC-8 equipped with the Airborne Synthetic Aperture Radar developed by scientists from NASA’s Jet Propulsion Laboratory. AirSAR will provide a baseline model and unprecedented mapping of the region. This data will make it possible to determine whether the warming trend is slowing, continuing or accelerating. AirSAR will also provide reliable information on ice shelf thickness to measure the contribution of the glaciers to sea level.

  4. COMMUNITY ENGAGEMENT IN CHILDREN’S ENVIRONMENTAL HEALTH RESEARCH

    PubMed Central

    Brenner, Barbara L.; Manice, Melissa P.

    2010-01-01

    Community engagement strategies and skills can build trust and reduce historical mistrust between researchers, communities and populations being studied, as well as contribute to the quality of study designs, methods and dissemination of findings. This review paper discusses why community engagement is of increasing importance in children’s environmental health research, describes models and the continuum of methods that are used and discusses their challenges and benefits. Two case studies, representing different study designs and using different community engagement models and methods, and lessons learned from these cases are described. Community engagement methods are best understood on a continuum based on the degree to which community members or representatives of community populations are involved in research planning, decision making and dissemination. Methods along this continuum include community consultation, community based participatory research(CBPR) and community consent to research. Community engagement knowledge and skills are especially important in the conduct of children’s environmental health research with its emphasis on reducing environmental risks at the community level; the increasing focus on genetics and gene-environment interactions; and the importance placed on translation of scientific results into behaviors and policies that protect the community. Across study designs, whether qualitative survey research, an observational epidemiology study, or a randomized intervention trial, understanding community interests, norms and values is necessary to describe attitudes and behaviors of specific population groups, build evidence of cause and effect between environmental exposures and health and/or that demonstrate the effectiveness of interventions to reduce risks.

  5. Use of supplemental food by breeding Ross's Geese and Lesser Snow Geese: Evidence for variable anorexia

    Gloutney, M.L.; Alisauskas, R.T.; Hobson, K.A.; Afton, A.D.

    1999-01-01

    Recent research suggests that foods eaten during laying and incubation play a greater role in supplying energy and nutrients to arctic-nesting geese than previously believed. We conducted food-supplementation experiments with Ross's Geese (Chen rossii) and Lesser Snow Geese (C. caerulescens) geese to evaluate: (1) if supplemental food was consumed by laying and incubating geese, (2) how food consumption influenced mass dynamics of somatic tissues of breeding geese, (3) if patterns of mass loss were consistent with fasting adaptations, and (4) whether energetic constraints would cause smaller Ross's Geese to consume more food relative to their body size than would larger Snow Geese. Quantity of supplemental food eaten by both species during laying and incubation was highly variable among individuals. Consumption of supplemental food during laying resulted in differences in overall body composition between control and treatment females. Treatment female Ross's Geese completed laying at a higher mass and with more abdominal fat than controls, whereas treatment female Snow Geese completed laying with heavier breast muscles and hearts. Overall body composition did not differ between control and treatment geese (both sexes and species) at the end of incubation, but treatment geese had heavier hearts than control geese. This suggests that treatment females did not rely to the same extent on metabolic adaptations associated with anorexia to meet energetic costs of incubation as did controls. Stable-nitrogen isotope analysis revealed patterns of protein maintenance during incubation consistent with metabolic adaptations to prolonged fasting. Our prediction that energetic constraints would cause smaller Ross's Geese to consume more food relative to their size than would Snow Geese was not supported. Mass-specific food consumption by Ross's Geese was 30% lower than that of Snow Geese during laying and 48% higher during incubation.

  12. Ross River Virus Transmission, Infection, and Disease: a Cross-Disciplinary Review

    2001-01-01

    Ross River virus (RRV) is a fascinating, important arbovirus that is endemic and enzootic in Australia and Papua New Guinea and was epidemic in the South Pacific in 1979 and 1980. Infection with RRV may cause disease in humans, typically presenting as peripheral polyarthralgia or arthritis, sometimes with fever and rash. RRV disease notifications in Australia average 5,000 per year. The first well-described outbreak occurred in 1928. During World War II there were more outbreaks, and the name epidemic polyarthritis was applied. During a 1956 outbreak, epidemic polyarthritis was linked serologically to a group A arbovirus (Alphavirus). The virus was subsequently isolated from Aedes vigilax mosquitoes in 1963 and then from epidemic polyarthritis patients. We review the literature on the evolutionary biology of RRV, immune response to infection, pathogenesis, serologic diagnosis, disease manifestations, the extraordinary variety of vertebrate hosts, mosquito vectors, and transmission cycles, antibody prevalence, epidemiology of asymptomatic and symptomatic human infection, infection risks, and public health impact. RRV arthritis is due to joint infection, and treatment is currently based on empirical anti-inflammatory regimens. Further research on pathogenesis may improve understanding of the natural history of this disease and lead to new treatment strategies. The burden of morbidity is considerable, and the virus could spread to other countries. To justify and design preventive programs, we need accurate data on economic costs and better understanding of transmission and behavioral and environmental risks. PMID:11585790

    Due to their sensitivity to environmental change, penguins in Antarctica are widely used as bio-indicators in paleoclimatic research. On the basis of bio-element assemblages identified in four ornithogenic sediment profiles, we reconstructed the historical penguin population change at Cape Bird, Ross Island, for the past 1600 years. Clear succession of penguin population peaks were observed in different profiles at about 1400 AD, which suggested a high probability of migration within this region. The succession was most obviously marked by a sand layer lasting from 1400 to 1900 AD in one of the analyzed profiles. Multiple physical/chemical parameters indicated this sand layer was not formed in a lacustrine environment, but was marine-derived. Both isostatic subsidence and frequent storms under the colder climatic condition of the Little Ice Age were presumed to have caused the abandonment of the colonies, and we believe the penguins migrated from the coastal area of mid Cape Bird northward and to higher ground as recorded in the other sediment profiles. This migration was an ecological response to global climate change and possible subsequent geological effects in Antarctica. PMID:26113152

    Geoscience is a multi-disciplinary field and in many cases its research benefits from considering different kinds of observational results. Geoscience observations are in some cases of direct interest also to the public. For these reasons effective knowledge transfer and access also across disciplines are especially important for research infrastructures (RIs) in the environmental domain. More generally, the ultimate success of a RI is measured by its scientific outcome and this is best achieved based on efficient access for a broad scientific community. In this presentation the authors report activities to develop governance tools so that the access to environmental RIs and to the data that they provide is common, fair and based on scientific rationale, regarding at the same time economically and technically reasonable use of limited resources. Implementing such governance tools will indeed foster and widen the access to RIs across environmental science domains while addressing societal challenges. The strategies also need to be flexible and sustainable over the expected lifetimes of the RIs. The reported activities involve researchers from different projects and environmental subdomains that come together in the project ENVRI_plus. ENVRI_plus is a Cluster project of RIs that brings together the current ESFRI roadmap RIs in the environmental domain and other relevant existing and developing RIs and projects. ENVRI_plus also offers opportunities for free-of-charge transnational access to four multi-disciplinary research platforms. These calls for access target research groups and companies wishing to conduct research or to test instruments for cross-disciplinary topics within the environmental domains atmosphere, biosphere, marine, and solid earth. They are initiated specifically to gain experience with access across different disciplines (further information is given at www.envriplus.eu).

    Ross Island is a volcanic complex that began forming with the emplacement Mount Bird around 5 million years ago, though it has developed most significantly within the last 1 million years with the emplacement of the c. 4km high Mount Erebus. Throughout this time, loading of the lithosphere by this volcanic complex has warped the underlying crust into a subcircular submarine depression that has been accumulating sediment in series of flexural moat basins around the periphery of the island. Due to the depth of the floor of the depression (800-1000 m below sea level today), the sediment fill has largely escaped subsequent erosion by grounded ice of the McMurdo and Ross Ice Shelves (MRIS) and Ross Ice Sheet. Our interest is in the 1.5 km-thick sedimentary record that now lies beneath the deepest part of the depression and is covered by the MRIS. The sediments here have the potential to provide a continuous and high resolution (10^2-10^3 year) record back to 5 million years of the past behaviour of the MRIS and its influence on bottom water production in Ross Sea. The flexural moat basin-fill between the volcanic complexes of Ross and White Islands, which because of its remoteness is only now being investigated for the first time, is in a key location beneath the north western corner of the Ross Ice Shelf (RIS) where it flows into the McMurdo Ice Shelf (MIS). This site forms one of the 4 objectives of the ANDRILL Programme and is scheduled for drilling in 2005. Here we present new multi-channel seismic reflection data from over-ice shelf surveys conducted between 2001-2003, that elucidate the geometry and stratigraphy of the flexural-moat basin-fill and its relationship to the adjacent volcanics. We illustrate the proposed drill sites and make an initial prognosis of the sedimentary fill. The uppermost c. 500 m of the sedimentary succession is expected to be fine-grained muds with occasional glacigene sediment and layers of volcanic ash. Underlying strata may become

    During the past century, environmental hazards have become a major concern, not only to public health professionals, but also to the society at large because of their tremendous health, socio-cultural and economic impacts. Various anthropogenic or natural factors have been implicated in the alteration of ecosystem integrity, as well as in the development of a wide variety of acute and/or chronic diseases in humans. It has also been demonstrated that many environmental agents, acting either independently or in combination with other toxins, may induce a wide range of adverse health outcomes. Understanding the role played by the environment in the etiology of human diseases is critical to designing cost-effective control/prevention measures. This special issue of International Journal of Environmental Research and Public Health includes the proceedings of the Twelfth International Symposium on Recent Advances in Environmental Health Research. The Symposium provided an excellent opportunity to discuss the scientific advances in biomedical, environmental, and public health research that addresses global environmental health issues.

    For the past 20 years, research on biodiversity and ecosystem functioning (B-EF) has only implicitly considered the underlying role of environmental change. We illustrate that explicitly reintroducing environmental change drivers in B-EF research is needed to predict the functioning of ecosystems facing changes in biodiversity. Next we show how this reintroduction improves experimental control over community composition and structure, which helps to provide mechanistic insight on how multiple aspects of biodiversity relate to function and how biodiversity and function relate in food webs. We also highlight challenges for the proposed reintroduction and suggest analyses and experiments to better understand how random biodiversity changes, as studied by classic approaches in B-EF research, contribute to the shifts in function that follow environmental change.

    The Fogarty International Training and Research Program in Environmental and Occupational Health at UC Berkeley concentrates on two major environmental health issues in the Indian subcontinent: arsenic in drinking water in West Bengal, India, and indoor air pollution in India and Nepal. Local trainees and researchers have had the opportunity to work on related research. Concerning arsenic in drinking water, projects included studies of skin lesions, pulmonary effects, reproductive outcomes, and child development, as well as mitigation approaches to reduce exposures. Activities in the indoor air pollution project have emphasized quantifying exposures to smoke from cooking and heating as well as their associations with tuberculosis and eye disease. Training has focused on developing skills necessary to address these problems. The training emphasizes in-country mentoring of trainees related to their research projects, and intensive short courses at partner institutions. The focus of capacity building in environmental health research in countries in economic and environmental transition should be on country-based research projects with embedded training efforts.

Studies were included in this review if they related to the environmental impacts of e-cigarettes. Scientific information on the environmental impacts of e-cigarette manufacturing, use and disposal is very limited. No studies formally evaluated the environmental impacts of the manufacturing process or disposal of components, including batteries. Four studies evaluated potential exposure to secondhand e-cigarette aerosol, an indication of impacts on indoor air quality. A 2010 survey of six e-cigarette models found that none of the products provided disposal instructions for spent cartridges containing nicotine. Notably, some e-cigarette manufacturers claim their e-cigarettes are 'eco-friendly' or 'green', despite the lack of any supporting data or environmental impact studies. Some authors argue that such advertising may boost sales and increase e-cigarette appeal, especially among adolescents. Little is known about the environmental impacts of e-cigarettes, and a number of topics could be further elucidated by additional investigation. These topics include potential environmental impacts related to manufacturing, use and disposal. The environmental impacts of e-cigarette manufacturing will depend upon factory size and the nicotine extracting method used. The environmental impacts of e-cigarette use will include chemical and aerosol exposure in the indoor environment. The environmental impacts of disposal of e-cigarette cartridges (which contain residual nicotine) and disposal of e-cigarettes (which contain batteries) represent yet another environmental concern.

    ABSTRACT The University of Wisconsin‐Madison Antarctic Automatic Weather Station (AWS) project has been making meteorological surface observations on the Ross Ice Shelf (RIS) for approximately 30 years. This network offers the most continuous set of routine measurements of surface meteorological variables in this region. The Ross Island area is excluded from this study. The surface climate of the RIS is described using the AWS measurements. Temperature, pressure, and wind data are analysed on daily, monthly, seasonal, and annual time periods for 13 AWS across the RIS. The AWS are separated into three representative regions – central, coastal, and the area along the Transantarctic Mountains – in order to describe specific characteristics of sections of the RIS. The climatology describes general characteristics of the region and significant changes over time. The central AWS experiences the coldest mean temperature, and the lowest resultant wind speed. These AWSs also experience the coldest potential temperatures with a minimum of 209.3 K at Gill AWS. The AWS along the Transantarctic Mountains experiences the warmest mean temperature, the highest mean sea‐level pressure, and the highest mean resultant wind speed. Finally, the coastal AWS experiences the lowest mean pressure. Climate indices (MEI, SAM, and SAO) are compared to temperature and pressure data of four of the AWS with the longest observation periods, and significant correlation is found for most AWS in sea‐level pressure and temperature. This climatology study highlights characteristics that influence the climate of the RIS, and the challenges of maintaining a long‐term Antarctic AWS network. Results from this effort are essential for the broader Antarctic meteorology community for future research. PMID:28008213

    Launched aboard the Space Shuttle Orbiter Atlantis on April 8, 2002, the STS-110 mission prepared the International Space Station (ISS) for future space walks by installing and outfitting the 43-foot-long Starboard side S0 (S-zero) truss and preparing the first railroad in space, the Mobile Transporter. The 27,000 pound S0 truss was the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first 'space railroad,' which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. STS-110 Extravehicular Activity (EVA) marked the first use of the Station's robotic arm to maneuver space walkers around the Station and was the first time all of a shuttle crew's space walks were based out of the Station's Quest Airlock. In this photograph, Astronaut Jerry L. Ross, mission specialist, anchored on the end of the Canadarm2, moves near the newly installed S0 truss. Astronaut Lee M. E. Morin, mission specialist, (out of frame), worked in tandem with Ross during this fourth and final scheduled session of EVA for the STS-110 mission. The final major task of the space walk was the installation of a beam, the Airlock Spur, between the Quest Airlock and the S0. The spur will be used by space walkers in the future as a path from the airlock to the truss.

Our objective was to establish the extent to which hospital environmental sustainability has been studied and the key issues that emerge for policy, practice and research. The PubMed, Engineering Village, Cochrane and King's Fund databases were searched for articles relating to hospital environmental sustainability published in English between 1 January 1990 and 1 October 2013. Further studies were found by review of reference lists. One hundred ninety-three relevant articles were found and 76 were selected for inclusion in the review. Common research themes were identified: hospital design, direct energy consumption, water, procurement, waste, travel and psychology and behaviour. Some countries (particularly the United Kingdom) have begun to invest systematically in understanding the environmental effects of hospitals. We found large variability in the extent of the evidence base according to topic. Research regarding the architectural fabric of hospital buildings is at a relatively mature stage. Similarly, there is a developed research base regarding devices and technologies used within hospitals to reduce the environmental effects of direct hospital energy and water use. Less is known about the clinical, psychological and social factors that influence how health care professionals use resources, travel to/from hospital, and interact with the buildings and technologies available. A significant part of the environmental footprint of hospitals relates to clinical practice, e.g. decisions regarding the use of pharmaceuticals and medical devices. Medical 'cradle to grave' life cycle assessment studies have been published to understand the full financial and environmental costs of hospital activities. The effects of preventive or demand management measures which avoid unnecessary hospital procedures are likely to be much greater than incremental changes to how hospital

    The ANDRILL Coulman High (CH) Project Site Surveys were an international effort conducted from November 2010 through January 2011. These surveys achieved all their primary and secondary objectives and resulted in an unexpected biological discovery at the lower boundary of the Ross Ice Shelf (RIS), which demonstrates the role of serendipity in scientific research. The surveys followed a safe traverse route to CH across the RIS using a ground-penetrating radar system supplemented by previously collected airborne radar. Four GPS stations and a weather station were established to monitor lateral and vertical ice motions and environmental conditions. A series of combined US-NZ field camps on the RIS were occupied and the ANDRILL hot water drill (HWD) system was used to melt numerous holes through 250-275 meters of ice shelf. Oceanographic moorings comprised of inductive sensors were deployed through the RIS at two sites and were recovered to the ice surface after two months. The NZ mooring was redeployed to conduct long-term observations through the water column at CH. Video camera observations of the interior and basal surface of the ice shelf and benthic observations of the seafloor were integrated with conductivity-temperature-depth (CTD) measurements at each site. The Submersible Capable of under-Ice Navigation and Imaging (SCINI) underwater remotely operated vehicle (ROV) was deployed at two sites through 260 meters of ice to explore the underside of the ice shelf while conducting operational testing. This was the first time that SCINI was deployed through an ice shelf. SCINI discovered an unusual biological community living in the ice at the lower surface of the ice shelf and recovered biological samples using an improvised suction pump sampler. These samples and extensive imagery are being further investigated to determine the nature of this newly discovered ecosystem. The biological discovery at the base of the RIS highlights the importance of continued

    Environmental health researchers often need to make difficult decisions on how to protect privacy and confidentiality when they conduct research in the home or workplace. These dilemmas are different from those normally encountered in clinical research. Although protecting privacy and confidentiality is one of the most important principles of research involving human subjects, it can be overridden to prevent imminent harm to individuals or if required by law. Investigators should carefully consider the facts and circumstances and use good judgment when deciding whether to breach privacy or confidentiality.

    In environmental health research, methods for quantitative analysis of human population studies data are gaining importance. In recent years, it has been realized that they can also provide an important link to the economic view on environmental health effects. In this review, fundamental concepts and methods from environmental epidemiology and health economics are presented and it is shown how they can be linked in order to support environmental policy decisions. In addition, the characteristics of environmental epidemiology and the role of epidemiologic studies in risk assessment are discussed. From the economic point of view, cost-of-illness studies and cost effectiveness studies are the main approaches, and we have placed special focus on methods of monetary valuation of health effects that are generally proposed in the environmental context. Two conceptually differing strategies to combine epidemiologic and economic evidence are presented: the environmental attributable fraction model as a top-down approach and the impact pathway approach which follows a bottom-up analysis strategy. Finally, two examples are used to illustrate the application of these concepts and methods: health risks caused by fine particle air pollution and their costs, and the cost-effectiveness of radon exposure reduction policies.

    The Environmental Systems Research Candidates (ESRC) Program, which is scheduled to end September 2001, was established in April 2000 as part of the Environmental Systems Research and Analysis Program at the Idaho National Engineering and Environmental Laboratory (INEEL) to provide key science and technology to meet the clean-up mission of the U.S. Department of Energy Office of Environmental Management, and perform research and development that will help solve current legacy problems and enhance the INEEL’s scientific and technical capability for solving longer-term challenges. This report documents the progress and accomplishments of the ESRC Program from April through September 2000. The ESRC Program consists of 24 tasks subdivided within four research areas: A. Environmental Characterization Science and Technology. This research explores new data acquisition, processing, and interpretation methods that support cleanup and long-term stewardship decisions. B. Subsurface Understanding. This research expands understanding of the biology, chemistry, physics, hydrology, and geology needed to improve models of contamination problems in the earth’s subsurface. C. Environmental Computational Modeling. This research develops INEEL computing capability for modeling subsurface contaminants and contaminated facilities. D. Environmental Systems Science and Technology. This research explores novel processes to treat waste and decontaminate facilities. Our accomplishments during FY 2000 include the following: • We determined, through analysis of samples taken in and around the INEEL site, that mercury emissions from the INEEL calciner have not raised regional off-INEEL mercury contamination levels above normal background. • We have initially demonstrated the use of x-ray fluorescence to image uranium and heavy metal concentrations in soil samples. • We increased our understanding of the subsurface environment; applying mathematical complexity theory to the problem of

    2014-12-01

    Models allow scientists and others to represent features and behaviors of environmental systems in order to promote inquiry, develop insights, test hypotheses, and consider solutions to problems. Environmental modeling also offers a way to include independent research on environmental issues in undergraduate classes, especially during winter when outdoor labs are more difficult. I will present on an Environmental Studies Topics course on Environmental Modeling taught at St. Olaf College during interim, including student feedback. The class used primary literature and hands on experiences with computer models to introduce environmentally relevant modeling tools. Topics covered in readings, lectures, or student presentations included process based models of disease, climate, ice, ecosystems, ecosystem services, hydrology, predator-prey systems, and competition among species for resources. Students conducted student-designed original research projects either by developing their own environmental model or by using existing models. Students participating in the class were environmental studies, economics, biology, math, or physics majors, although the class was open to all students who were "comfortable thinking quantitatively". No prior programming experience was required as a prerequisite, although students who had previous experience with R or Matlab were able to design more complex models. The students were graded on their class participation in discussions, several modeling "checkpoint" assignments designed to monitor progress, and on 4 in-class presentations designed to foster a collaborative atmosphere and improve communication skills. While the course was taught over a month-long interim "semester", students were evenly divided in their feedback about whether they would prefer the course in that format or in a semester-long format.

  17. Seismic Stratigraphy of the Ross Island Flexural Basin, West Antarctica

    NASA Astrophysics Data System (ADS)

    Wenman, C. P.; Harry, D. L.; Jha, S.

    2014-12-01

    Marine seismic reflection data collected over the past 30+ years in the Ross Sea region of southwest Antarctica has been tied to the ANDRILL and CIROS boreholes to develop a seismic stratigraphic model that constrains the spatial and temporal evolution of the flexural basin surrounding Ross Island. Ross Island was formed from 4.6 Ma to present by extrusive volcanism in the Ross Sea at the southern end of the Terror Rift. Preliminary mapping has identified a hinge zone trending northeastward from Mt. Bird, separating the well-developed flexural moat on the west side of the island from sub-horizontal strata on the northeast and east sides. The flexural moat on the west and north-northwest sides of the island is approximately 40-45 km wide with sediment fill thickness of roughly 1100 m. Seismic lines to the east and northeast of the island do not indicate the presence of a flexural moat. Instead, the thickness of strata on the east side of the island that are time-equivalent to the infill of the flexural moat on the west side remains constant from the Coulman High westward to within ~28 km of Ross Island (the landward extent of the seismic data coverage). The concordant post-Miocene strata on the east and northeast sides of Ross Island imply either that the flexural basin does not extend more than ~28 km eastward from the Ross Island shoreline, or that the flexural basin is not present on that side of the island. The first scenario requires that the elastic strength of the lithosphere differ on either side of the hinge. The second scenario can be explained by a mechanical rupture in the lithosphere beneath Ross Island, with Ross Island acting as an end-load on a mechanical half-plate that forms the lithosphere beneath Ross Island and westward. In this model, the lithosphere east of Ross Island and the hinge forms a second half-plate, bearing little or none of the Ross Island volcanic load.

    This is an account of some of the accomplishments of the health and environmental research program performed in national laboratories, universities, and research institutes. Both direct and indirect societal benefits emerged from the new knowledge provided by the health and environmental research program. In many cases, the private sector took this knowledge and applied it well beyond the mission of supporting the defense and energy needs of the Nation. Industrial and medical applications, for example, have in several instances provided annual savings to society of $100 million or more. The form of this presentation is, in fact, through "snapshots" - examples of significant, tangible accomplishments in each of the areas at certain times to illustrate the role and impact of the research program. The program's worth is not necessarily confined to such accomplishments; it extends, rather, to its ability to identify and help solve potential health and environmental problems before they become critical. This anticipatory mission has been pursued with an approach that combines applied problem solving with a commitment to fundamental research that is long-term and high-risk. The narrative of this research program concludes with a perspective of its past and a prospectus on its future.

    The Environmental Systems Research (ESR) Program, a part of the Environmental Systems Research and Analysis (ESRA) Program, was implemented to enhance and augment the technical capabilities of the INEEL. Strengthening the Technical capabilities of the INEEL will provide the technical base to serve effectively as the Environmental Management Laboratory for the Office of Environmental Management (EM). This is a progress report for the third year of the ESR Program (FY 2000). A report of activities is presented for the five ESR research investment areas: (1) Transport Aspects of Selective Mass Transport Agents, (2) Chemistry of Environmental Surfaces, (3) Materials Dynamics, (4) Characterization Science, and (5) Computational Simulation of Mechanical and Chemical Systems. In addition to the five technical areas, the report describes activities in the Science and Technology Foundations element of the program, e.g., interfaces between ESR and the EM Science Program (EMSP) and the EM Focus Areas. The five research areas are subdivided into 18 research projects. FY 2000 research in these 18 projects has resulted in more than 50 technical papers that are in print, in press, in review, or in preparation. Additionally, more than 100 presentations were made at professional society meetings nationally and internationally. Work supported by this program was in part responsible for one of our researchers, Dr. Mason Harrup, receiving the Department of Energy’s “Bright Light” and “Energy at 23” awards. Significant accomplishments were achieved. Non-Destructive Assay hardware and software was deployed at the INEEL, enhancing the quality and efficiency of TRU waste characterization for shipment. The advanced tensiometer has been employed at numerous sites around the complex to determine hydrologic gradients in variably saturated vadose zones. An ion trap, secondary ion mass spectrometer (IT-SIMS) was designed and fabricated to deploy at the INEEL site to measure the

    Blood pressure (BP) is affected by many environmental factors including ambient temperature, altitude, latitude, noise, and air pollutants. Given their pervasiveness, it is plausible that such factors may also have an impact on hypertension prevalence and control rates. Health care providers should be aware that the environment can play a significant role in altering BP. Although not among the established modifiable risk factors (eg, obesity) for hypertension, reducing exposures when pertinent should be considered to prevent or control hypertension. The authors provide a concise review of the evidence linking diverse environmental factors with BP and suggest an approach for incorporating this knowledge into clinical practice. The authors propose using the term environmental hypertensionology to refer to the study of the effects of environmental factors on BP in clinical and research settings. © 2011 Wiley Periodicals, Inc.

  2. The concept of externality: Implications for TVA Environmental Research Center

    SciTech Connect

    Foster, T.H.

    1994-06-01

    Pollution of the environment is a result of the economic activities of production and consumption. And although the market system is touted as the superior method of organizing and operating an economic system, society frequently is dissatisfied with some of the side effects. In these cases of market failure, a cry for intervention often is raised to obtain more socially-desirable solutions. Environmental pollution is one symptom of market failure. If the TVA Environmental Research Center is to focus on defining solutions to environmental problems and designing policy options for implementing such solutions, its efforts should benefit from an understanding of why the market fails and how it may be adjusted to produce more socially-desirable results. The purposes of this report are to: (1) promote an appreciation for and understanding of the concept of externality; (2) demonstrate the utility of the concept in the design and packaging of policy and technology for improved environmental performance; (3) provide a brief summary of the externality valuation issue currently being debated by the electric power industry; and (4) identify environmental research and development agenda opportunities or strategic considerations suggested for the Center by this review.

    The global environment is in critical decline. Whether one's concern about environmental epidemiology stems from the perspectives of environmental health, climate change, ecological collapse, or growing inequity, clear problems exist. Natural capital resources are being depleted; disregard for the integrity of ecosystems is entrenched in current business practices. Indeed, despite increasing rhetoric to the contrary, the disregard displayed by those who hold power globally toward long-term sustainability and, thus, the health and well-being of future generations, could be described as wanton. Six years ago, the Millennium Development Goals were announced by the United Nations as a rallying point for action to achieve a sustainable future, particularly by reducing the gap between the "have mores" and "have nots." The attainment of these Goals is now endangered, as is, apparently, the spirit of optimism and idealism that inspired them at the Millennium Summit. We call for a reinvigoration of both concern about-and action on-sustainability. In particular, we appeal to those engaged in the field of environmental epidemiology (and other specialties with whom they engage) to consider how they might help by incorporating sustainability issues (including global ecological integrity and global environmental justice) into their own research programs. This incorporation would make a vital contribution to protect both present and future generations and to reduce resource and health gaps between North and South. Simply put, we propose that sustainability becomes integral to advancing the science of environmental epidemiology and related environmental disciplines.

    The characterization and remediation of contaminated sites are complex endeavors fraught with numerous challenges. One particular challenge that is receiving increased attention is the development and encouragement of full participation by communities and community members affected by a given site in all facets of decision-making. Many disciplines have been grappling with the challenges associated with environmental and risk communication, public participation in environmental data generation, and decision-making and increasing community capacity. The concepts and methods developed by these disciplines are reviewed, with a focus on their relevance to the specific dynamics associated with environmental contamination sites. The contributions of these disciplines are then synthesized and integrated to help develop Environmental Research Translation (ERT), a proposed framework for environmental scientists to promote interaction and communication among involved parties at contaminated sites. This holistic approach is rooted in public participation approaches to science, which includes: a transdisciplinary team, effective collaboration, information transfer, public participation in environmental projects, and a cultural model of risk communication. Although there are challenges associated with the implementation of ERT, it is anticipated that application of this proposed translational science method could promote more robust community participation at contaminated sites.

  8. EDITORIAL: The need and challenge for Environmental Research Letters

    NASA Astrophysics Data System (ADS)

    Kammen, Daniel M.

    2006-11-01

    Why another journal? This is the inevitable question that every effort to launch a new journal must, and should, address. A common statistic in the business world is that nine out of ten new restaurants fail. In the academic world something similar, but less definitive, can happen: a potentially interesting, but practically flawed, effort can be launched, never truly build an intellectual community, but then continue as a sub-critical, little-known journal for far too long. The challenge any new publication, academic or professional, faces is thus extreme. A new journal must find a way to usefully compete, and bring new value, in the face of multiple existing outlets for significant results, tremendous barriers to establishing a 'track record' or 'name recognition' against existing publications, and a print and a cyberspace increasingly desperate in the search for 'content', scientific or otherwise. In the case of Environmental Research Letters (ERL), however, these questions answered themselves and, as a result, I cannot imagine a more critically needed new publication. Indeed, the goal of ERL is to be more than simply one more good new journal. It is to be a place—both physical and online—that those engaged in environmental issues—from researchers within the physical and natural sciences, to those concerned with applied systems studies, modeling and simulation techniques, practical engagement in environmental activism, and developing, conducting or critiquing policy, legal, or business efforts—will all want to go to read, and to engage with colleagues. The environmental field has witnessed an incredible intellectual and professional proliferation. The areas of ecological resilience, global change science, policy, law and economics, industrial ecology, green buildings, environmental genomics, environmental archaeology, and the sociology of environmental movements have become increasingly regarded and, to varying degrees, recognized themselves as major

    This article reviews a variety of ethical issues one must consider when conducting research on environmental health interventions on human subjects. The paper uses the Kennedy Krieger Institute lead abatement study as well as a hypothetical asthma study to discuss questions concerning benefits and risks, risk minimization, safety monitoring, the duty to warn, the duty to report, the use of control groups, informed consent, equitable subject selection, privacy, conflicts of interest, and community consultation. Research on environmental health interventions can make an important contribution to our understanding of human health and disease prevention, provided it is conducted in a manner that meets prevailing scientific, ethical, and legal standards for research on human subjects.

    the highest rate of increase in sea ice coverage of any of five standard divisions of the Southern Ocean, although the Weddell Sea, Indian Ocean, and Western Pacific Ocean all also had sea ice increases, while only the Bellingshausen/Smundsen Seas experienced overall sea ice decreases. Overall, the Southern Ocean sea ice cover increased at an average rate of 10,800 plus or minus 2,500 square kilometers per year between November 1978 and December 2007, with every month showing positive values although with some of these values not being statistically significant. The sea ice increase since November 1978 was preceded by a sharp decrease in Southern Ocean ice coverage in the 1970's and is in marked contrast to the decrease in Arctic sea ice coverage that has occurred both in the period since November 1978 and since earlier in the 1970's. On a yearly average bases, for 1979-2007 the Southern Ocean sea ice extent increased at a rate of 1.0 plus or minus 0.4% per decade, whereas the Arctic ice extent decreased at the much greater rate of 4.0 plus or minus 0.4 percent per decade (closer to the % per decade rate of increase in the Ross Sea). Considerable research is ongoing to explain the differences.

    At present, the extent of environmental health research in Australia is unclear and there are no recent overarching reviews of national publications on the subject. This study investigates the current status of environmental health research in Australia using a bibliometric analysis. Three databases (Medline, Web of Science, and AUSTHealth) were used to access original, peer-reviewed journal articles with Australian data published between 1 January 2001 and 11 June 2010. A total of 337 articles from 174 different journal titles were used in the analysis and were classified according to 15 pre-determined environmental health areas. The highest number of articles related to water health and resources (66 articles), exposure to hazardous chemicals (57 articles), and air pollution including indoor air (58 articles). These areas made up 54% of the total publication output over the past 10 years. The amount of environmental health research published in Australia over the past 10 years, and the topics explored in these studies, is comparable to that of other countries of similar socio-economic status.

    Environmental news mainly reach not specialist people by mass media, which generally focuses on fascinating or catastrophic events without reporting scientific data. Otherwise, scientific data on environment are published in peer-reviewed journals with specific language, so they could be not understandable to common people. In the last decade, Internet spread made easier to divulge environmental information. This allows everyone (scientist or not) to publish information without revision. In fact, World Wide Web includes many scientific sites with different levels of confidence. Within Italian scientific websites, there are those of University and Research Centre, but they mainly contain didactic and bureaucratic information, generally lacking in research news, or reporting them in peer-reviewed format. University and Research Centre should have an important role to divulge certified information, but news should be adapted to a general audience without scientific skills, in order to help population to gain knowledge on environmental issues and to develop responsible behavior. Therefore, an attractive website (www.sunability.unina2.it) has been created in order to divulge research products of Environmental, Biological and Pharmaceutical Sciences and Technologies Department (DiSTABiF) of Second University of Naples-SUN (Campania, Southern Italy). This website contains divulgation articles derived from peer-reviewed publications of DiSTABiF researchers and concerning studies on environmental, nutrition, and health issues, closely related topics. Environmental studies mainly referred to Caserta district (Southern Italy), where DiSTABiF is located. Divulgation articles have been shared by main social networks (Facebook: sunability, Twitter: @SUNability) and accesses have been monitored for 28 days in order to obtain demographic and geographic information about users and visualization number of both DiSTABiF website and social network pages.

  1. Cretaceous and Tertiary extension throughout the Ross Sea, Antarctica

    USGS Publications Warehouse

    Decesari, Robert C.; Wilson, Douglas C.; Luyendyk, Bruce P.; Faulkner, Michael

    2007-01-01

    Marine geophysical data from the deep sea adjacent to the Ross Sea, Antarctica suggest that 70 km of extension occurred between East and West Antarctica from 46 to 2 Ma. The Northern and Victoria Land Basins in the western Ross Sea adjacent to the Transantarctic Mountains accommodated 95 km of this extension. Several kilometers of Oligocene sediments are found in the Central Trough and Eastern Basin in the eastern Ross Sea. Subsidence modeling accounts for these accumulations with about 40 km of extension in each basin centered on 35 Ma; therefore Ross Sea-wide Tertiary extension was comparable to extension in the deep-sea system. The early Tertiary geometry was of one oceanic rift that branched into at least three rifts in the continental lithosphere. This pattern is likely due to the contrast of physical properties and thermal state between the two different lithospheres at the continent-ocean boundary.

    Environmental health research is a relatively new scientific area with much interdisciplinary collaboration. Regardless of which human population is included in field studies (e.g., general population, working population, children, elderly, vulnerable sub-groups, etc.) their conduct must guarantee well acknowledged ethical principles. These principles, along with codes of conduct, are aimed at protecting study participants from research-related undesired effects and guarantee research integrity. A central role is attributed to the need for informing potential participants (i.e., recruited subjects who may be enrolled in a study), obtaining their written informed consent to participate, and making them aware of their right to refuse to participate at any time and for any reason. Data protection is also required and communication of study findings must respect participant's willingness to know or not know. This is specifically relevant for studies including biological markers and/or storing biological samples that might be analysed years later to tackle research objectives that were specified and communicated to participants at the time of recruitment or that may be formulated after consent was obtained. Integrity is central to environmental health research searching for causal relations. It requires open communication and trust and any violation (i.e., research misconduct, including fabrication or falsification of data, plagiarism, conflicting interests, etc.) may endanger the societal trust in the research community as well as jeopardize participation rates in field projects.

  12. Retreat history of the last glacial maximum ice sheet in Ross Sea, Antarctica

    NASA Astrophysics Data System (ADS)

    Shipp, Stephanie Staples

    High-resolution geophysical and geologic data were acquired in western and central Ross Sea, Antarctica, to determine the: (1) maximum extent and configuration of the ice sheet during the Last Glacial Maximum (LGM); (2) conditions and processes at the base of the expanded ice sheet and their role in ice stream activity; and (3) relative retreat history of the ice sheet. This information can provide geologic constraints for modeling of ice-sheet retreat. The research formed the basis for development of a public Web site (http://www.glacier.rice.edu) and for middle-school earth-science instructional materials. Based on identification of isolated grounding-zone wedges and consistency of mega-scale glacial lineations, the LGM ice edge reached the Coulman Island region in western Ross Sea. The maximum extent in central Ross Sea occurred at the continental-shelf edge, based on the presence of mega-scale glacial lineations, glacio-tectonic features, and shelf-edge gullies. Streaming ice, overlying a deforming bed typically <5 m in thickness, filled the troughs. Thinner, divergent, slower moving ice, not underlain by deforming sediment, occupied the bank tops. The ice sheet eroded and conveyed sediment from the inner regions toward the outer shelf, where the material was deposited at the grounding line. No features associated with meltwater occur; water available to the subglacial system probably was incorporated into a deforming unit. The ice sheet may have undergone an initial phase of mass wasting, based the large, arcuate iceberg furrows associated with the grounding zones. Ice retreated first from western Ross Sea, possibly because of a diminished contribution from the East Antarctic Ice Sheet. Ice retreat from central Ross Sea lagged that of western Ross Sea. The banks remained ice covered after ice retreat from the troughs; ice shelves may have covered the troughs. During retreat, the grounded ice reworked the substrate into back-stepping grounding-zone wedges and

Participants were housed at the Montclair State University's field station situated in the middle of 30,000 acres of mature forest, mountain ridges and freshwater streams and lakes within the Kittatinny Mountains of Northwest New Jersey, Program emphases were placed on development of project planning skills, analytical skills, creativity, critical thinking and scientific report preparation. Ten students were recruited in spring with special focus on recruiting students from underrepresented groups and community colleges. Students were matched with their individual research interests including hydrology, erosion and sedimentation, environmental chemistry, and ecology. In addition to research activities, lectures, educational and recreational field trips, and discussion on environmental ethics and social justice played an important part of the program. The ultimate goal of the program is to facilitate participants' professional growth and to stimulate the participants' interests in pursuing Earth Science as the future career of the participants.

    Federal funding agencies increasingly support stakeholder participation in environmental health studies, and yet there is very little published research on engagement of community members in the development of data disclosure (DD) strategies. The Ohio Environmental Protection Agency reported airborne manganese (Mn) concentrations in East Liverpool, Ohio, 30 times higher than the reference concentration, which led to an academic–community research partnership to address community concern about Mn exposure, particularly among children. Children and their families were recruited to participate in a pilot study. Samples of blood and hair were collected from the children and analyzed for metals. DD mechanisms were developed using an iterative approach between community and academic partners. Individual DD letters were mailed to each participating family, and a community meeting was held. A post-meeting survey was administered to gauge community perception of the DD strategies. The purpose of this article is to demonstrate the effectiveness of engaging community partners in the conduct of environmental health research and in the development of DD strategies for individuals and the community at large. Scientists should include community partners in the development of DD strategies to enhance translation of the research findings and support the right of study participants to know their individual results.

    2010-12-01

    Public awareness of the state of the ocean is growing with issues such as climate change, over-harvesting, marine pollution, coral bleaching, ocean acidification and sea level rise appearing regularly in popular media outlets. Society is also placing greater value on the range of ecosystem services the ocean provides. This increased consciousness of environmental change due to a combination of anthropogenic activities and impacts from climate change offers scientists the opportunity of engaging citizens in environmental research. The term citizen science refers to scientific research carried out by citizens and led by professionals, which involves large scale data collection whilst simultaneously engaging and educating those who participate. Most projects that engage citizen scientists have been specifically designed to provide an educational benefit to the volunteer and benefit the scientific inquiry by collecting extensive data sets over large geographical areas. Engaging the public in environmental science is not a new concept and successful projects (such as the Audobon Christmas Bird Count and Earthwatch) have been running for several decades resulting in hundreds of thousands of people conducting long-term field research in partnership with scientists based at universities worldwide. The realm of citizen science projects is continually expanding, with public engagement options ranging from science online; to backyard afternoon studies; to fully immersive experiential learning projects running for weeks at a time. Some organisations, such as Earthwatch also work in partnership with private industry; giving scientists access to more funding opportunities than those avenues traditionally available. These scientist -industry partnerships provide mutual benefits as the results of research projects in environments such as coastal ecosystems feed directly back into business risk strategies; for example mitigating shoreline erosion, storm surges, over fishing and

    Antarctic Bottom Water of the world ocean is derived from dense Shelf Water that is carried downslope by gravity currents at specific sites along the Antarctic margins. Data gathered by the AnSlope and CLIMA programs reveal the presence of energetic gravity currents that are formed over the western continental slope of the Ross Sea when High Salinity Shelf Water exits the shelf through Drygalski Trough. Joides Trough, immediately to the east, offers an additional escape route for less saline Shelf Water, while the Glomar Challenger Trough still farther east is a major pathway for export of the once supercooled low-salinity Ice Shelf Water that forms under the Ross Ice Shelf. The Drygalski Trough gravity currents increase in thickness from ˜100 to ˜400 m on proceeding downslope from ˜600 m (the shelf break) to 1200 m (upper slope) sea floor depth, while turning sharply to the west in response to the Coriolis force during their descent. The mean current pathway trends ˜35° downslope from isobaths. Benthic-layer current and thickness are correlated with the bottom water salinity, which exerts the primary control over the benthic-layer density. A 1-year time series of bottom-water current and hydrographic properties obtained on the slope near the 1000 m isobath indicates episodic pulses of Shelf Water export through Drygalski Trough. These cold (<-1 °C), salty (>34.75) pulses correlate with strong downslope bottom flow. Extreme examples occurred during austral summer/fall 2003, comprising concentrated High Salinity Shelf Water (-1.9 °C; 34.79) and approaching 1.5 m s -1 at descent angles as large as ˜60° relative to the isobaths. Such events were most common during November-May, consistent with a northward shift in position of the dense Shelf Water during austral summer. The coldest, saltiest bottom water was measured from mid-April to mid-May 2003. The summer/fall export of High Salinity Shelf Water observed in 2004 was less than that seen in 2003. This

    2003-04-01

    The Ross Sea polynya is a complex oceanographic feature with a strong influence on the heat balances of the Ross Sea. The opening of the Ross Sea polynya depends on three main factors: the katabatic surges associated with the cyclogenesys events on the Siple coast, the katabatic flow down the glaciers in the Eastern Ross Sea and the katabatic winds blowing from the Transantarctic Mountains, which are turned aside by Ross Island (Bromwich et al., 1998). In this work, the polynya opening and closure in 1999 is studied. A flux model (Biggs et al. 2000) is applied to a few case study in order to describe the polynya behaviour. Heat fluxes and sea ice production will be evaluated by using bulk formulae. The meteorological input for the calculations are provided by the European Center for Medium-range Weather Forecasting. Sea ice concentration data will be used in order to validate the model. Daily ice concentration data were retrieved by using the Sea Lion algorithm to obtain maps of the polynya area with a spatial resolution of 12.5x12.5km2 (Kern and Heygster, 2001; Kern, 2001). This is achieved using the polarization difference of 85GHz brightness temperatures acquired by the Special Sensor Microwave/Imager (SSM/I). This study focuses on the Ross Sea Polynya, but nevertheless the Terra Nova Bay polynya case will be investigated.

    To effectively manage the nation's energy and natural resources, government and industry leaders need accurate information regarding the performance and economics of advanced energy systems and the costs and benefits of public-sector initiatives. The Energy and Environmental Systems Division (EES) of Argonne National Laboratory conducts applied research and development programs that provide such information through systems analysis, geophysical field research, and engineering studies. During 1981, the division: analyzed the production economics of specific energy resources, such as biomass and tight sands gas; developed and transferred to industry economically efficient techniques for addressing energy-related resource management and environmental protection problems, such as the reclamation of strip-mined land; determined the engineering performance and cost of advanced energy-supply and pollution-control systems; analyzed future markets for district heating systems and other emerging energy technologies; determined, in strategic planning studies, the availability of resources needed for new energy technologies, such as the imported metals used in advanced electric-vehicle batteries; evaluated the effectiveness of strategies for reducing scarce-fuel consumption in the transportation sector; identified the costs and benefits of measures designed to stabilize the financial condition of US electric utilities; estimated the costs of nuclear reactor shutdowns and evaluated geologic conditions at potential sites for permanent underground storage of nuclear waste; evaluated the cost-effectiveness of environmental regulations, particularly those affecting coal combustion; and identified the environmental effects of energy technologies and transportation systems.

    The characterization and remediation of contaminated sites are complex endeavors fraught with numerous challenges. One particular challenge that is receiving increased attention is the development and encouragement of full participation by communities and community members affected by a given site in all facets of decision-making. Many disciplines have been grappling with the challenges associated with environmental and risk communication, public participation in environmental data generation and decision-making, and increasing community capacity. The concepts and methods developed by these disciplines are reviewed, with a focus on their relevance to the specific dynamics associated with contaminated sites. The contributions of these disciplines are then synthesized and integrated to help develop Environmental Research Translation (ERT), a proposed framework for environmental scientists to promote interaction and communication among involved parties at contaminated sites. This holistic approach is rooted in public participation approaches to science, which includes: a transdisciplinary team, effective collaboration, information transfer, public participation in environmental projects, and a cultural model of risk communication. Although there are challenges associated with the implementation of ERT, it is anticipated that application of this proposed translational science method could promote more robust community participation at contaminated sites.

    Summary Asbestos-related diseases continue to result in approximately 120,000 deaths every year in the United States and worldwide. Although extensive research has been conducted on health effects of occupational exposures to asbestos, many issues related to environmental asbestos exposures remain unresolved. For example, environmental asbestos exposures associated with a former mine in Libby, Montana, have resulted in high rates of nonoccupational asbestos-related disease. Additionally, other areas with naturally occurring asbestos deposits near communities in the United States and overseas are undergoing investigations to assess exposures and potential health risks. Some of the latest public health, epidemiological, and basic research findings were presented at a workshop on asbestos at the 2014 annual meeting of the Society of Toxicology in Phoenix, Arizona. The following focus areas were discussed: a) mechanisms resulting in fibrosis and/or tumor development; b) relative toxicity of different forms of asbestos and other hazardous elongated mineral particles (EMPs); c) proper dose metrics (e.g., mass, fiber number, or surface area of fibers) when interpreting asbestos toxicity; d) asbestos exposure to susceptible populations; and e) using toxicological findings for risk assessment and remediation efforts. The workshop also featured asbestos research supported by the National Institute of Environmental Health Sciences, the Agency for Toxic Substances and Disease Registry, and the U.S. Environmental Protection Agency. Better protection of individuals from asbestos-related health effects will require stimulation of new multidisciplinary research to further our understanding of what constitutes hazardous exposures and risk factors associated with toxicity of asbestos and other hazardous EMPs (e.g., nanomaterials).

    Background The scientific discoveries of health risks resulting from methylmercury exposure began in 1865 describing ataxia, dysarthria, constriction of visual fields, impaired hearing, and sensory disturbance as symptoms of fatal methylmercury poisoning. Objective Our aim was to examine how knowledge and consensus on methylmercury toxicity have developed in order to identify problems of wider concern in research. Data sources and extraction We tracked key publications that reflected new insights into human methylmercury toxicity. From this evidence, we identified possible caveats of potential significance for environmental health research in general. Synthesis At first, methylmercury research was impaired by inappropriate attention to narrow case definitions and uncertain chemical speciation. It also ignored the link between ecotoxicity and human toxicity. As a result, serious delays affected the recognition of methylmercury as a cause of serious human poisonings in Minamata, Japan. Developmental neurotoxicity was first reported in 1952, but despite accumulating evidence, the vulnerability of the developing nervous system was not taken into account in risk assessment internationally until approximately 50 years later. Imprecision in exposure assessment and other forms of uncertainty tended to cause an underestimation of methylmercury toxicity and repeatedly led to calls for more research rather than prevention. Conclusions Coupled with legal and political rigidity that demanded convincing documentation before considering prevention and compensation, types of uncertainty that are common in environmental research delayed the scientific consensus and were used as an excuse for deferring corrective action. Symptoms of methylmercury toxicity, such as tunnel vision, forgetfulness, and lack of coordination, also seemed to affect environmental health research and its interpretation. PMID:20529764

    RV Del is an intrinsic pulsating variable star in the constellation Delphinus, discovered by Ross (1926). The AAVSO list RV Del as a RRAB type of variable star. RV Del has been found to have a magnitude that varies from 12.9 - 14.2 and a period of 11.9553 hours.The purpose of our research of RV Del is to confirm and improve previous results as well as explore different methods to engage middle school students in the scientific method and astronomy. The SKYNET network of telescopes allows students to request images from a group of international research class telescopes. The telescope request process allows students first-hand experience in astronomy while the data analysis allows students to understand advance software systems to produce publishable results. Data is being gathered using the SKYNET network and Stone Edge Observatory to gather photometry of RV Del and create a new light curve. Findings will be presented the January 2017 AAS.

  12. Odd cloud in the Ross Sea, Antarctica

    2002-01-01

    On January 28, 2002, MODIS captured this image of an interesting cloud formation in the boundary waters between Antarctica's Ross Sea and the Southern Ocean. A dragon? A snake? A fish? No, but it is an interesting example of the atmospheric physics of convection. The 'eye' of this dragon-looking cloud is likely a small spot of convection, the process by which hot moist air rises up into the atmosphere, often producing big, fluffy clouds as moisture in the air condenses as rises into the colder parts of the atmosphere. A false color analysis that shows different kinds of clouds in different colors reveals that the eye is composed of ice crystals while the 'body' is a liquid water cloud. This suggests that the eye is higher up in the atmosphere than the body. The most likely explanation for the eye feature is that the warm, rising air mass had enough buoyancy to punch through the liquid water cloud. As a convective parcel of air rises into the atmosphere, it pushes the colder air that is higher up out of its way. That cold air spills down over the sides of the convective air mass, and in this case has cleared away part of the liquid cloud layer below in the process. This spilling over of cold air from higher up in the atmosphere is the reason why thunderstorms are often accompanied by a cool breeze.

    Following the Ross operation, pulmonary autografts tend to dilate over time. This study researches the fate of the pulmonary autograft - at 4.5 years following the modified Ross operation - with special reference to the impact of the modification on (a) pulmonary autograft dilatation, (b) the neo-aortic root geometry, (c) neo-aortic valve function and (d) the coronary artery reserve. A total of 26 patients who underwent the Ross operation were included in this study; of these, 13 consecutive patients underwent a modified Ross operation in which the free-standing autograft root was supported externally by a Dacron vascular prosthetic jacket (DVPJ). These patients were compared to a cohort of 13 matched patients who were operated on using the conventional Ross technique; all patients were followed up prospectively by echocardiography studies. The patients who underwent the modified Ross operation were also subjected to bicycle ergometry. At the 47-month median follow-up, there was no significant increase in the size of the entire neo-aortic root in the patients who underwent the modified Ross operation; in addition, the geometry of the neo-aortic root was also preserved and the left ventricular function had improved significantly, whilst the aortic valve function and excursion remained satisfactory. All patients, with one exception, in the modified Ross operation group exhibited normal exercise capacity. By contrast, there were significant differences in diameters of the aortic root - between the two surgical techniques in favour of the modified Ross technique - following a median follow-up of 23 months in the patients subjected to the conventional Ross operation. Provision of external support to the entire pulmonary autograft with a DVPJ prevents its dilatation following free-standing pulmonary autograft Ross operation when evaluated at the 4.5-year follow-up. The function and the geometry of the neo-aortic root are not affected negatively by this modification and

    The increasing interest for the environmental problems and the study of the impact on the environment due to antropic activity produced an enhancement of remote sensing applications. The Italian National Research Council (CNR) established a new laboratory for airborne hyperspectral imaging, the LARA Project (Laboratorio Aero per Ricerche Ambientali - Airborne Laboratory for Environmental Research), equipping its airborne laboratory, a CASA-212, mainly with the Daedalus AA5000 MIVIS (Multispectral Infrared and Visible Imaging Spectrometer) instrument. MIVIS's channels, spectral bandwidths, and locations are chosen to meet the needs of scientific research for advanced applications of remote sensing data. MIVIS can make significant contributions to solving problems in many diverse areas such as geologic exploration, land use studies, mineralogy, agricultural crop studies, energy loss analysis, pollution assessment, volcanology, forest fire management and others. The broad spectral range and the many discrete narrow channels of MIVIS provide a fine quantization of spectral information that permits accurate definition of absorption features from a variety of materials, allowing the extraction of chemical and physical information of our environment. The availability of such a hyperspectral imager, that will operate mainly in the Mediterranean area, at the present represents a unique opportunity for those who are involved in environmental studies and land-management to collect systematically large-scale and high spectral-spatial resolution data of this part of the world. Nevertheless, MIVIS deployments will touch other parts of the world, where a major interest from the international scientific community is present.

    Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month involved the Dry Sorbent Injection (DST) test block with the Carbon Injection System. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit, the 0.4 MW Mini-Pilot Wet Scrubber, and the 4.0 MW Pilot Wet Scrubber remained idle this month in a cold-standby mode and were inspected regularly. These units remain available for testing as future project work is identified. The 1990 Clean Air Act Amendments have required that the Environmental Protection Agency (EPA) assess the health risks and environmental effects associated with air toxic emissions (primarily mercury) from fossil-fuel fired utility boilers. EPRI has sponsored research on environmental mercury since 1983 to determine the factors that may influence human health, and to determine the role of electric power generating stations in contributing to those factors. Over the last four years, EPRI`s Environmental Control Technology Center (ECTC) has conducted EPRI and DOE sponsored testing to develop and demonstrate appropriate measurement methods and control technologies for power plant atmospheric mercury emissions. Building upon the experience and expertise of the EPRI ECTC, a test program was initiated at the Center in July to further evaluate dry sorbent-based injection technologies upstream of a cold-side ESP for mercury control, and to determine the effects of such sorbents on ESP performance. The results from this program will be compared to the results from previous DOE/EPRI demonstrations, and to other ongoing programs. The primary objectives of this test program are to: (1) Determine the levels of mercury removal achievable by dry sorbent injection upstream of an electrostatic precipitator (ESP). The process parameters to be investigated include sorbent residence time, sorbent type, sorbent size, sorbent loading, and flue gas

    The Yosemite Research Training in Environmental Science offers undergraduate students a unique opportunity to actively experience field research in Environmental Science in a premier National Park, over a nine-week period in the summer. The Yosemite REU is a collaboration between three institutions: the University of California at Merced, Yosemite National Park, and the USGS Western Ecological Research Center. Student activities mainly consist of individual research projects, spanning a broad range of disciplines such as Ecology, Geosciences, Biodiversity, Conservation, Restoration, and Hydrology. All projects include a strong field component. Students are exposed to the benefits of multi-disciplinary research in weekly meetings in which all students talk about their most recent work. Students present their research in Yosemite Valley at the end of the program before a public audience (including visitors). Research training is provided by mentors from UC Merced (Schools of Natural Sciences, Engineering, and Social Sciences) and the USGS Western Ecological Research Center. In addition to their interactions with their mentors and other faculty, students have opportunities to meet with NPS professionals engaged in park-related activities, to learn more about the integration of science with resources management and about potential careers in research and science outside academia. Students also participate in field trips led by UCM, USGS, and NPS scientists, focusing on Yosemite and the Sierra Nevada. Students attend a weekly seminar in Environmental Science with a broad diversity of speakers, including researchers as well as other science-related professionals, such as freelance science writers and illustrators, as well as NPS scientists and staff. Finally, student participants engage in several other activities, including outreach (e.g., a day-long meeting with high-school Central Valley students from underrepresented minorities).

    The Terrestrial Ecology group continued its involvement in the National Crop Loss Assessment Network, and studies of O/sub 3/ effects on winter wheat and soybeans were completed. Experiments on O/sub 3/ x SO/sub 2/ interactions on soybeans were also performed. The Microcosms for Acid Rain Studies (MARS) project had its first full year of research and much information concerning acid rain impacts on soil-plant systems was collected. A study of the influence of temporal variations in rain acidity on soybean productivity was also initiated. The aquatic radiochemistry group continued measurements of the mobility of plutonium and americium at a disposal site at Los Alamos and initiated similar work at Hanford. Laboratory tracer experiments were carried out to study the adsorptive behavior of neptunium, the solubility limits of plutonium, and the influence of rare earth concentration on the sorption and redox behavior of plutonium. The soil-plant process group initiated several studies on the influence of mycorrhizae to host plants in disturbed and natural environments. Much of the past research has been concerned with understanding mycorrhizal fungi propagule dynamics as related to disturbances associated with energy extraction. Future research will be directed at understanding how below-ground symbiotic associations may increase the fitness of host plants. Emphasis is being placed on resource acquisition and compartmental strategies. Separate analytics have been indexed for EDB.

    This Environmental Assessment has been prepared to determine if the Carlsbad Environmental Monitoring and Research Center (the Center), or its alternatives would have significant environmental impacts that must be analyzed in an Environmental Impact Statement. DOE`s proposed action is to continue funding the Center. While DOE is not funding construction of the planned Center facility, operation of that facility is dependent upon continued funding. To implement the proposed action, the Center would initially construct a facility of approximately 2,300 square meters (25,000 square feet). The Phase 1 laboratory facilities and parking lot will occupy approximately 1.2 hectares (3 acres) of approximately 8.9 hectares (22 acres) of land which were donated to New Mexico State University (NMSU) for this purpose. The facility would contain laboratories to analyze chemical and radioactive materials typical of potential contaminants that could occur in the environment in the vicinity of the DOE Waste Isolation Pilot Plant (WIPP) site or other locations. The facility also would have bioassay facilities to measure radionuclide levels in the general population and in employees of the WIPP. Operation of the Center would meet the DOE requirement for independent monitoring and assessment of environmental impacts associated with the planned disposal of transuranic waste at the WIPP.

  6. Linking research and policy to ensure children's environmental health.

    PubMed Central

    1998-01-01

    The U.S. Environmental Protection Agency (U.S. EPA) has made protecting children's environmental health its highest priority. Data on how and when children may be at risk are vital for accomplishing this goal. Recent examples of the link between research and policy include U.S. EPA actions to carry out the recommendations of the National Academy of Sciences on pesticides in children's food, reduce and prevent childhood lead poisoning, and revise national ambient air quality standards for ozone and particulate matter. Today, the Food Quality Protection Act (FQPA), which makes protecting children from pesticide residues in food a national priority, is contributing to the growing need for data for decision making. Further impetus comes from provisions in the FQPA and 1996 Safe Drinking Water Act Amendments for establishing a screening and testing program for potential risks from endocrine disruptors. Another factor is the analysis that will be required under President William J. Clinton's executive order directing all federal agencies, for the first time, to reduce environmental health and safety risks to children. Success of the U.S. international commitment to protect children is directly tied to the strength and availability of environmental data. To meet such challenges, the U.S. EPA is revising key science policies, expanding research opportunities, and adding to the public's right-to-know tools. In this dynamic climate, there are growing opportunities for the research community to play a greater role in helping ensure the well-being of children living today and in generations to come.

  7. Seismicity in the vicinity of Ross Island, Antarctica

    NASA Astrophysics Data System (ADS)

    Rowe, C. A.; Kienle, J.

    1986-12-01

    Earthquakes in the Ross Sea, Antarctica, are of two types: volcanic, and those which appear to be of tectonic origin. Volcanic events in the vicinity of Ross Island are associated exclusively with Mount Erebus, Ross Island; this volcano erupts regularly, generating several earthquakes per day whose characteristics are quite distinct from non-volcanic events. These nonvolcanic earthquakes are recognizable by their distinct P- and S-wave arrivals, and a lack of the high frequency, often monochromatic character typical of Erebus events. One hundred fifty-seven tectonic microearthquakes (M < 2.0) were recorded in 1983 and 1984 by the ten station network on Ross Island; these events were located using the least-squares routine, HYPOELLIPSE. Of these events, 106 have RMS residual traveltime errors of less than or equal to 0.6 seconds; they are clustered in the vicinity of Ross Island, but are not restricted to it. There is a linear trend of epicenters cutting across the island and continuing northward. Most activity seems to center beneath Mount Terra Nova, between Mount Erebus and Mount Terror. Mean depth for events is 8.2 km; however, depths are rather evenly distributed over a range of 0 to 25 km. Modelling based on Bouger gravity anomalies and seismic refraction studies indicates a depth to the Moho of about 40 km beneath the continent, shallowing to 27 km beneath the Ross Sea. This 27 km depth is approximately equal to the lower limit of the tectonic seismicity detected by the Erebus network; hence, events are of crustal origin. These data suggest, with the rift-type geochemistry of Erebus' magma, that the Ross Sea is a site of active crustal extension and rifting.

  8. Glacial history of Prince Gustav Channel and James Ross Island

    During the Last Glacial Maximum (LGM) in Antarctica, circa 18 cal. ka BP, ice draining from northeast Antarctic Peninsula and an ice dome over James Ross Island coalesced in Prince Gustav Channel. These glaciers formed a palaeo-ice stream flowing northwards and southwards to the shelf edge, resulting in an ice divide off northwest James Ross Island. However, this record is largely derived from marine sediment cores and swath bathymetry. The onshore interaction of Antarctic Peninsula-derived ice and an extended Mount Haddington Ice Cap on James Ross Island remains uncertain, and chronostratigraphy is poor, being largely based on radiocarbon dates, which are influenced by the large marine reservoir effect. A key issue is the age of the glacial incursion that deposited the granite erratics on Ulu Peninsula. Our hypothesis is that James Ross Island was initially inundated by a thick Antarctic Peninsula Ice Sheet, which deposited the inland and high-elevation erratic boulders on James Ross Island. During deglaciation, this ice sheet was subsequently drained by fast-flowing ice streams including the ice stream that developed in the Prince Gustav Channel. At this time the Antarctic Peninsula Ice Sheet ice was thinner and therefore only impinged on the coastal fringes of James Ross Island. We therefore anticipate that the inland and high-elevation granite boulders on basalt-rich glacial deposits will yield the age of pre-LGM ice advances of the Antarctic Peninsula Ice Sheet onto James Ross Island, and that the erratic boulders associated with glacial deposits enriched in Trinity Peninsula erratics at low-lying coastal sites will represent the age of the deglacial Prince Gustav Ice Stream.

    The long-term performance of polymer-based composites in the space environment is discussed. Both thermoset and thermoplastic matrix composites are included in this discussion. Previous efforts on the space environmental effects on composites are briefly reviewed. Focus of this review is placed on the effects of hygrothermal stresses, atomic oxygen, ultraviolet (UV), and space debris/micrometeoroid impacts along with the potential synergism. Potential approaches to estimating the residual strength of polymer composites after exposure to atomic oxygen erosion or space debris/micrometeoroid impact are evaluated. New ground-based data are then utilized to illustrate the effects of atomic oxygen and thermal cycling on the failure behavior of polymer composites. Finally, research needs, challenges, and opportunities in the field of space environmental effects on composite materials are highlighted.

    The European ENVRI project (Common operations of Environmental Research Infrastructures) is addressing common ICT solutions for the research infrastructures as selected in the ESFRI Roadmap. More specifically, the project is looking for solutions that will assist interdisciplinary users who want to benefit from the data and other services of more than a single research infrastructure. However, the infrastructure architectures, the data, data formats, scales and granularity are very different. Indeed, they deal with diverse scientific disciplines, from plate tectonics, the deep sea, sea and land surface up to atmosphere and troposphere, from the dead to the living environment, and with a variety of instruments producing increasingly larger amounts of data. One of the approaches in the ENVRI project is to design a common Reference Model that will serve to promote infrastructure interoperability at the data, technical and service levels. The analysis of the characteristics of the environmental research infrastructures assisted in developing the Reference Model, and which is also an example for comparable infrastructures worldwide. Still, it is for users already now important to have the facilities available for multi-disciplinary data discovery and data processing. The rise of systems research, addressing Earth as a single complex and coupled system is requiring such capabilities. So, another approach in the project is to adapt existing ICT solutions to short term applications. This is being tested for a few study cases. One of these is looking for possible coupled processes following a volcano eruption in the vertical column from deep sea to troposphere. Another one deals with volcano either human impacts on atmospheric and sea CO2 pressure and the implications for sea acidification and marine biodiversity and their ecosystems. And a third one deals with the variety of sensor and satellites data sensing the area around a volcano cone. Preliminary results on these

  14. Mg/Casea surface temperatures during the Marine Isotope Stage 31 collapse of the Ross Ice Shelf

    2012-04-01

    The recovery of the AND-1b and CRP-1 drill cores from the Southwest Ross Sea highlighted the potential instability in of the Ross Ice Shelf and the West Antarctic Ice Sheet it buttresses. Both cores recovered a few individuals of the planktonic foraminifera Neogloboquadrina pachyderma from marine isotope stage (MIS) 31. This interval is significant because it marks the youngest occurrence of open ocean diatom sediment at AND-1b, which is now situated under the McMurdo Ice Shelf, indicating a substantial retreat of the Ross Ice Shelf occurred during this interglacial. However, sediment deposited after MIS 31 at both sites is represented only by glacial-dominated sediment, suggesting a critical environmental threshold had been crossed enabling the Ross Ice Shelf to form and persist. Numerical modeling by Pollard and DeConto (Nature, 2009) suggested that sub-ice oceanic melting is a critical element in the stability of ice shelves and that "WAIS will begin to collapse when nearby ocean temperatures warm by roughly 5°C." Laser ablation ICPMS measurement of the Mg/Ca content of N. pachyderma shows that although there is considerable heterogeneity in the distribution of Mg in their tests the mean Mg/Ca of a sample population appears proportional to calcification temperature. By empirically calibrating Mg/Ca in CRP-1 N. pachyderma against values measured in modern populations collected from Ross Sea and Southern Ocean sites with SSTs ranging from 1.2°C to 14°C it is concluded that SST during MIS 31 was warmer than today by 5-9°C, consistent with model projections.

    An epidemic of Ross River virus infection occurred in the Cook Islands early in 1980 and affected the majority of the inhabitants of Rarotonga, the most populated island in the group. This represents the easternmost extension of the virus which, until 1979, was believed limited to Australia, New Guinea, and the Solomon Islands. The clinical manifestations of Ross River disease, predominantly polyarthritis, did not differ significantly from those observed previously in Australia. However, unlike the experience in Australia, where Ross River virus has never been isolated from a patient with polyarthritis, the agent was recovered from the serum of one-half of approximately 100 such patients with serologically proven infections. It is not known if this latter observation is the result of a change in the virus, the different virus isolation technique employed, or other factors. It was found that the incubation period of the disease could be as short as 3 days--much less than previously suspected. Ross River virus was isolated from six pools of Aedes polynesiensis mosquitoes collected in nature and it appeared that this species was the most probable vector on Rarotonga. In view of the widespread distribution of Ae. polynesiensis on islands, in the eastern Pacific it would not be surprising if Ross River virus occurs in other previously unaffected areas in the future.

    In support of the Department of Homeland Security / Science and Technology Directorate’s (DHS/S&T) creation of a new position called the Radiological Operations Support Specialist (ROSS), Lawrence Livermore National Laboratory (LLNL) in Sub-task 1.1 and 1.2 has assisted in the development of the ROSS skills, knowledge, and abilities (SKAs); identified potentially relevant training; cross-mapped the training to the SKAs; and identified gaps in the training related to the SKAs, as well as their respective level of training knowledge - current versus desired. In the follow on task, Sub-task 1.3, a 5 day ROSS Pilot Training course was developed to fill the priority gaps identified in Sub-Task 1.2. Additionally, in Sub-Task 1.5, LLNL has performed a gap analysis of electronic tools, handbooks, and job-aides currently available to the ROSS and developed recommendations for additional and next generation tools to ensure the operational effectiveness of the ROSS position. This document summarizes the feedback received from the instructors and pilot course observers on what worked in the course and what could be improved as well as an assessment of the Pre- and Post-Test administered to the students.

    This research was undertaken to estimate the societal benefits and costs of selected past research performed for the Office of Health and Environmental Research (OHER) of the US Department of Energy (DOE). Three case studies of representative OHER and DOE research were performed. One of these, the acid rain case study, includes research conducted elsewhere in DOE. The other two cases were the OHER marine research program and the development of high-purity germanium that is used in radiation detectors. The acid rain case study looked at the research benefits and costs of furnace sorbent injection and duct injection, technologies that might reduce acid deposition precursors. Both appear to show benefits in excess of costs. We examined in detail one of the OHER marine research program's accomplishments - the increase in environmental information used by the Outer Continental Shelf leasing program to manage bidding for off-shore oil drilling. The results of an econometric model show that environmental information of the type supported by OHER is unequivocally linked to government and industry leasing decisions. The germanium case study indicated that the benefits of germanium radiation detectors were significant.

    In recent years, requests for proposals more frequently emphasize outreach to stakeholder communities, decision support, and science that serves societal needs. Reports from the National Academy of Sciences and Western States Water Council emphasize the need for science translation and outreach, in order to address societal concerns with climate extremes, such as drought, the use of climate predictions, and the growing challenges of climate change. In the 1990s, the NOAA Climate Program Office developed its Regional Integrated Sciences and Asssessments program to help bridge the gap between climate science (notably, seasonal predictions) and society, to improve the flow of information to stakeholders, and to increase the relevance of climate science to inform decisions. During the same time period, the National Science Foundation initiated multi-year Science and Technology Centers and Decision Making Under Uncertainty Centers, with similar goals, but different metrics of success. Moreover, the combination of population growth, climate change, and environmental degradation has prompted numerous research initiatives on linking knowledge and action for sustainable development. This presentation reviews various models and methodologies for translating science results from field, lab, or modeling work to use by society. Lessons and approaches from cooperative extension, boundary organizations, co-production of science and policy, and medical translational research are examined. In particular, multi-step translation as practiced within the health care community is examined. For example, so- called "T1" (translation 1) research moves insights from basic science to clinical research; T2 research evaluates the effectiveness of clinical practice, who benefits from promising care regimens, and develops tools for clinicians, patients, and policy makers. T3 activities test the implementation, delivery, and spread of research results and clinical practices in order to foster

  19. Miocene Antarctic ice dynamics in the Ross Embayment (Western Ross Sea, Antarctica): Insights from provenance analyses of sedimentary clasts in the AND-2A drill core

    2016-11-01

    A detailed study of gravel-size sedimentary clasts in the ANDRILL-2A (AND-2A) drill core reveals distinct changes in provenance and allows reconstructions to be produced of the paleo ice flow in the McMurdo Sound region (Ross Sea) from the Early Miocene to the Holocene. The sedimentary clasts in AND-2A are divided into seven distinct petrofacies. A comparison of these with potential source rocks from the Transantarctic Mountains and the coastal Southern Victoria Land suggests that the majority of the sedimentary clasts were derived from formations within the Devonian-Triassic Beacon Supergroup. The siliciclastic-carbonate petrofacies are similar to the fossiliferous erratics found in the Quaternary Moraine in the southern McMurdo Sound and were probably sourced from Eocene strata that are currently hidden beneath the Ross Ice Shelf. Intraformational clasts were almost certainly reworked from diamictite and mudstone sequences that were originally deposited proximal to the drill site. The distribution of sedimentary gravel clasts in AND-2A suggests that sedimentary sequences in the drill core were deposited under two main glacial scenarios: 1) a highly dynamic ice sheet that did not extend beyond the coastal margin and produced abundant debris-rich icebergs from outlet glaciers in the central Transantarctic Mountains and South Victoria Land; 2) and an ice sheet that extended well beyond the coastal margin and periodically advanced across the Ross Embayment. Glacial scenario 1 dominated the early to mid-Miocene (between ca. 1000 and 225 mbsf in AND-2A) and scenario 2 the early Miocene (between ca. 1138 and 1000 mbsf) and late Neogene to Holocene (above ca. 225 mbsf). This study augments previous research on the clast provenance and highlights the added value that sedimentary clasts offer in terms of reconstructing past glacial conditions from Antarctic drill core records.

    Use of resorbable external reinforcement of the pulmonary autograft during the Ross operation has been suggested, but the differential regional potential for dilation of the aorta, mainly regarding the neo-root and the neo-Valsalva sinuses, represents an unresolved issue. Auxetic materials could be useful in preventing dilation given their favorable mechanical properties. We designed a composite semiresorbable armoured bioprosthesis constituted by polydioxanone and expanded polytetrafluoroethylene and evaluated its effectiveness as a pulmonary autograft reinforcement device in an animal model of the Ross procedure. An experimental model of the Ross procedure was performed in 20 three-month-old growing lambs. The pulmonary autograft was alternatively nonreinforced (control group n = 10) or reinforced with composite bioprosthesis (reinforced group n = 10). Animals were followed up during growth for 6 months by angiography and echocardiography. Specific stainings for extracellular matrix and immunohistochemistry for metalloproteinase-9 were performed. Reference aortic diameter increased from 14 ± 1 mm to 19 ± 2 mm over 6 months of growth. In the control group, pulmonary autograft distension (28 ± 2 mm) was immediately noted, followed by aneurysm development at 6 months (40 ± 2 mm, P < .001 vs reference). In the reinforced group, an initial dilation to 18 ± 1 mm was detected and the final diameter was 27 ± 2 mm (42% increase). Two deaths due to pulmonary autograft rupture occurred in the control group. On histology, the control group showed medial disruption with connective fibrous replacement, whereas in the reinforced group compensatory intimal hyperplasia was present in the absence of intimal tears. The bioprosthesis promoted a positive matrix rearrangement process favoring neoarterialization and elastic remodeling as demonstrated on specific staining for elastin collagen and metalloproteinase-9. The device adapted and functionally compensated for the

    Beginning in the 1950s and 1960s, an abundance of effort and initiative was focused on propelling the space industry outward for planetary exploration and habitation. During these early years, the push to take space science to new levels indirectly contributed to the evolution of another science field that would not fully surface until the early 1980s, environmental remediation. This field is associated with the remediation or cleanup of environmental resources such as groundwater, soil, and sediment. Because the space-exploration initiative began prior to the establishment of the U.S. Environmental Protection Agency (EPA) in December of 1970, many NASA Centers as well as space-related support contractors allowed for the release of spent chemicals into the environment. Subsequently, these land owners have been directed by the EPA to responsibly initiate cleanup of their impacted sites. This paper will focus on the processes and lessons learned with the development, testing, and commercialization initiatives associated with four remediation technologies. The technologies include installation techniques for permeable reactive barriers (PRBs), the use of ultrasound to improve long-term performance of PRBs, emulsified zero-valent iron for product-level solvent degradation, and emulsion technologies for application to metal and polychlorinated biphenyl contaminated media. Details of the paper cover technology research, evaluation, and testing; contracts and grants; and technology transfer strategies including patenting, marketing, and licensing.

    The U.S. Geological Survey (USGS) Tennessee Water Science Center and the College of Engineering and Technology at Tennessee State University developed a Partnership in Environmental Education and Research (PEER) to support environmental research at TSU and to expand the environmental research capabilities of the USGS in Tennessee. The PEER program is driven by the research needs to better define the occurrence, fate, and transport of contaminants in groundwater and surface water. Research in the PEER program has primarily focused on the transport and remediation of organic contamination in karst settings. Research conducted through the program has also expanded to a variety of media and settings. Research areas include contaminant occurrence and transport, natural and enhanced bioremediation, geochemical conditions in karst aquifers, mathematical modeling for contaminant transport and degradation, new methods to evaluate groundwater contamination, the resuspension of bacteria from sediment in streams, the use of bioluminescence and chemiluminescence to identify the presence of contaminants, and contaminant remediation in wetlands. The PEER program has increased research and education opportunities for students in the College of Engineering, Technology, and Computer Science and has provided students with experience in presenting the results of their research. Students in the program have participated in state, regional, national and international conferences with more than 140 presentations since 1998 and more than 40 student awards. The PEER program also supports TSU outreach activities and efforts to increase minority participation in environmental and earth science programs at the undergraduate and graduate levels. TSU students and USGS staff participate in the TSU summer programs for elementary and high school students to promote earth sciences. The 2007 summer camps included more than 130 students from 20 different States and Washington DC.

    2016-04-01

    Environmental and geoscientific research infrastructures (RIs) are dedicated to distinct aspects of the ocean, atmosphere, ecosystems, or solid Earth research, yet there is significant commonality in the way they conceive, develop, operate and upgrade their observation systems and platforms. Many environmental Ris are distributed network of observatories (be it drifting buoys, geophysical observatories, ocean-bottom stations, atmospheric measurements sites) with needs for remote operations. Most RIs have to deal with calibration and standardization issues. RIs use a variety of measurements technologies, but this variety is based on a small, common set of physical principles. All RIs have set their own research and development priorities, and developed their solution to their problems - however many problems are common across RIs. Finally, RIs may overlap in terms of scientific perimeter. In ENVRIplus we aim, for the first time, to identify common opportunities for innovation, to support common research and development across RIs on promising issues, and more generally to create a forum to spread state of the art techniques among participants. ENVRIplus activities include 1) measurement technologies: where are the common types of measurement for which we can share expertise or common development? 2) Metrology : how do we tackle together the diversified challenge of quality assurance and standardization? 3) Remote operations: can we address collectively the need for autonomy, robustness and distributed data handling? And 4) joint operations for research: are we able to demonstrate that together, RIs are able to provide relevant information to support excellent research. In this process we need to nurture an ecosystem of key players. Can we involve all the key technologists of the European RIs for a greater mutual benefit? Can we pave the way to a growing common market for innovative European SMEs, with a common programmatic approach conducive to targeted R&D? Can we

    Background Environmental health researchers frequently study people in occupational, educational, recreational, or domestic settings who are exposed to hazardous agents. Objective/discussion Deciding whether—and how—to inform research subjects about risks they face in their environment can be a challenging task for investigators. Because legal rules and professional guidelines do not cover this topic, investigators must carefully consider their ethical obligations in light of the facts and circumstances. Conclusion To navigate through this dilemma, investigators should consider the evidence for the risks, the nature of the risks, the usefulness of risk information to the subjects, and the effects on the study and community of informing subjects about risks.

    President Barack Obama's State of the Union message, delivered on 24 January, touched on the need for basic research, energy production, support for clean energy, and environmental protection, but it included just one passing reference to climate change. In addition, the speech made no note of the Administration's recent denial of a controversial application for the Keystone XL pipeline to transport crude oil from Canada to the United States and made just an elliptical reference regarding the bankrupt Solyndra Corporation, which the administration had touted as a clean energy company. Innovation "demands basic research," Obama said, adding that Congress should not "gut these investments in our budget." Noting that one promise for innovation is American-made energy, Obama said he is directing the administration to "open more than 75% of our potential offshore oil and gas resources."

    This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from September 17, 2000, shows the B15 family of icebergs that calved off the Ross Ice Shelf in March of 2000, at the end of the Antarctic summer melt season. The enormous bergs were locked up in winter sea ice before they could drift very far that first season, but at the onset of the winter thaw, soon after this image was acquired, the bergs began to drift. The large, southernmost berg is B-15, and it eventually drifted over toward Ross Island, seen at the bottom left of the image. The amazing shadow being cast on the ground south of Ross Island is from Mt. Erebus.

    Coastal zone color scanner (CZCS) imagery of the western Ross Sea revealed the presence of an intense phytoplankton bloom covering >106,000 square kilometers in early December 1978. This bloom developed inside the Ross Sea polynya, within 2 weeks of initial polynya formation in late November. Primary productivity calculated from December imagery (3.9 grams of carbon per square meter per day) was up to four times the values measured during in situ studies in mid-January to February 1979. Inclusion of this early season production yields a spring-to-summer estimate of 141 to 171 grams of carbon per square meter, three to four times the values previously reported for the western Ross Sea.

    The Navy Remote Ocean Sensing System (N-ROSS) Dynamic Stability Study team concluded that the frozen April 1985 design was viable and contained no show stoppers, although it was also clear from the study results that the configuration required further optimization. While the frozen N-ROSS configuration used has since been superceded, and the vehicle is now under competitive procurement, several other results remain from the study that will have lasting value to the N-ROSS program. The importance of constructing an integrated simulation, to serve as a design and verification aid, has been clearly established. The two team approach to the study afforded the Navy a higher degree of confidence in the results than could have been accomplished by a single simulation, and the approach led to results that highlighted subtleties in the model and simulation development that surely would have been overlookded without the benefit of an independent companion simulation with which to compare it.

  18. Subsurface mapping of the Ross Island flexural basin, southwest Antarctica

    NASA Astrophysics Data System (ADS)

    Wenman, Christopher P.

    Ross Island is a post-Miocene (< 4.6 Ma) volcanic island located in the Ross Sea region of southwest Antarctica. This region of Antarctica borders the western edge of the West Antarctic Rift System, along the Transantarctic Mountain front. Marine and over-ice multi-channel seismic reflection surveys and borehole studies targeting the Ross Sea region over the last 30+ years have been used in this study to develop a seismic stratigraphic model of the development and evolution of the Ross Island flexural basin. Four key stratigraphic horizons were identified and mapped to fully capture the basin-fill, as well as strata lying above and below the flexural basin. From oldest to youngest these horizons are named RIB-m, RIM-g, RIM-b and RIB-r. Time structure, isochron and isochore maps were created for the horizons and the stratigraphic intervals they bound. The seismic stratigraphic record shows the Ross Island flexural moat formation post-dates the main tectonic subsidence phase within the Victoria Land Basin. The maps presented here are the first to fully illustrate the evolution of the Ross Island flexural basin. The maps highlight depositional patterns of two distinct periods of flexural subsidence and basin-filling superimposed on the older N-S trending Victoria Land Basin depocenter. Two units of flexural basin fill, Unit FFI between horizons RIM-g and RIM-b (the oldest flexural basin fill), and Unit FFII between horizons RIM-b and RIB-r (the youngest flexural basin fill) are associated with the two periods of flexural subsidence. Flexural moat subsidence and subsequent filling occurred episodically during periods of active volcanism on the island. Unit FFI is estimated to range from ca. 4 to 2 Ma, corresponding with formation of the Mt. Bird volcanic edifice on Ross Island. Unit FFII ranges in age from ca. 2 to 1 Ma, and is related to Mt. Terror, Mt. Erebus, and Hut Point Peninsula volcanism. The isochore maps suggest the depocenter of the flexural basin during

  20. Legacy of Environmental Research During the Space Shuttle Program

    Lane, Helen W.

    2011-01-01

    The Space Shuttle Program provided many opportunities to study the role of spaceflight on human life for over the last 30 years and represents the longest and largest U.S. human spaceflight program. Risks to crewmembers were included in the research areas of nutrition, microbiology, toxicology, radiation, and sleep quality. To better understand the Shuttle environment, Crew Health Care System was developed. As part of this system, the Environmental Health Subsystem was developed to monitor the atmosphere for gaseous contaminants and microbial contamination levels and to monitor water quality and radiation. This program expended a great deal of effort in studying and mitigating risks related to contaminations due to food, water, air, surfaces, crewmembers, and payloads including those with animals. As the Shuttle had limited stowage space and food selection, the development of nutritional requirements for crewmembers was imperative. As the Shuttle was a reusable vehicle, microbial contamination was of great concern. The development of monitoring instruments that could withstand the space environment took several years and many variations to come up with a suitable instrument. Research with space radiation provided an improved understanding of the various sources of ionizing radiation and the development of monitoring instrumentation for space weather and the human exposure within the orbiter's cabin. Space toxicology matured to include the management of offgassing products that could pollute the crewmembers air quality. The Shuttle Program implemented a 5-level toxicity rating system and developed new monitoring instrumentation to detect toxic compounds. The environment of space caused circadian desynchrony, sleep deficiency, and fatigue leading to much research and major emphasis on countermeasures. Outcomes of the research in these areas were countermeasures, operational protocols, and hardware. Learning Objectives: This symposium will provide an overview of the

    The objective of this study was to review environmental equity research on outdoor air pollution and, specifically, methods and tools used in research, published in English, with the aim of recommending the best methods and analytic tools. English language publications from 2000 to 2012 were identified in Google Scholar, Ovid MEDLINE, and PubMed. Research methodologies and results were reviewed and potential deficiencies and knowledge gaps identified. The publications show that exposure to outdoor air pollution differs by social factors, but findings are inconsistent in Canada. In terms of study designs, most were small and ecological and therefore prone to the ecological fallacy. Newer tools such as geographic information systems, modeling, and biomarkers offer improved precision in exposure measurement. Higher-quality research using large, individual-based samples and more precise analytic tools are needed to provide better evidence for policy-making to reduce environmental inequities.

    Our planet is dynamic; energy and matter constantly move between the hydrosphere, atmosphere and lithosphere on time scales from seconds to millenia. These tight interactions - including those between organisms and their physical environment - are what make Earth habitable. However, as Rachel Carson wrote, 'Only within the moment of time represented by the present century has one species - man - acquired significant power to alter the nature of this world'. Globalization and explosive population growth have generated far-reaching environmental problems on a scale that humanity has never faced before. Fortunately, our species has also developed an unprecedented ability to provide science-based solutions. Since processes impacting the environment involve complex biological, physical, chemical and geological interactions and feedbacks, they require the integration of expertise from all these scientific disciplines as well as input from policy makers, social scientists, and economists. This talk presents four examples of current interdisciplinary research projects conducted in my lab, each one related to a theme from one of Carson's books (Under the Sea-wind, The Sea Around Us, The Edge of the Sea, and Silent Spring). These projects, and others like them, provide hope that we can move toward a sustainable relationship with the natural world by encouraging the best scientists to conduct interdisciplinary research with direct applications for environmental management and stewardship.

    Cardiovascular effects of noise rank second in terms of disability-adjusted life year (DALYs) after annoyance. Although research during the past decade has consolidated the available data base, the most recent meta-analysis still shows wide confidence intervals - indicating imprecise information for public health risk assessment. The alpine area of Tyrol in the Austrian part of the Alps has experienced a massive increase in car and heavy goods traffic (road and rail) during the last 35 years. Over the past 25 years small-, middle-, and large-sized epidemiological health surveys have been conducted - mostly within the framework of environmental health impact assessments. By design, these studies have emphasized a contextually driven environmental stress perspective, where the adverse health effects on account of noise are studied in a broader framework of environmental health, susceptibility, and coping. Furthermore, innovative exposure assessment strategies have been implemented. This article reviews the existing knowledge from these studies over time, and presents the exposure-response curves, with and without interaction assessment, based on standardized re-analyses and discusses it in the light of past and current cardiovascular noise effects research. The findings support relevant moderation by age, gender, and family history in nearly all studies and suggest a strong need for consideration of non-linearity in the exposure-response analyses. On the other hand, air pollution has not played a relevant role as a moderator in the noise-hypertension or the noise-angina pectoris relationship. Finally, different noise modeling procedures can introduce variations in the exposure response curves, with substantive consequences for public health risk assessment of noise exposure.

    Schools on Board (www.arcticnet.ulaval.ca) was created in 2002 to address the outreach objectives of a network of Canadian scientists conducting research in the High Arctic. The program was piloted with great success with the 2004 research program called the Canadian Arctic Shelf Study (CASES). Since then, the S/B program continues as an integral outreach program of the Canadian Network of Centres of Excellence (NCE) known as ArcticNet. The primary objective of the program is to bridge Arctic climate change research with science and environmental education in the public school system. It is a vehicle for scientists and graduate students to share their research program with high schools and the general public. The program encourages schools to include Arctic Sciences into their science programs by linking Arctic research to existing curriculum, providing resources and opportunities to send high school students and teachers into the Arctic to participate in a science expedition on board the Canadian research icebreaker CCGS Amundsen. The field program is an adventure into Arctic research that exposes students and teachers to the objectives and methods of numerous science teams representing a number of research disciplines and institutions from across Canada and beyond. Face-to-face interactions with scientists of all levels (masters, PhD's, researchers, CRC chairs), hands-on experiences in the field and in the labs, and access to state-of-the-art scientific instrumentation, combine to create a powerful learning environment. In addition to hands-on research activities the program introduces participants to many aspects of Canada's North, including local knowledge related to climate change, culture, history, and politics - within the educational program on the ship and the planned visits to Northern communities. During International Polar Year (IPY) Schools on Board collaborated with international researchers and northern agencies from 11 countries to offer one

    The nature of the environmental issues facing our nation demands a capability that allows us to enhance economic vitality, maintain environmental quality, and limit threats to life and property through more fundamental understanding of the Earth. It is "advanced" knowledge of how the system may respond that gives environmental information most of its power and utility. This fact is evident in the demand for new forecasting products, involving air quality, energy demand, water quality and quantity, ultraviolet radiation, and human health indexes. As we demonstrate feasibility and benefit, society is likely to demand a growing number of new operational forecast products on prediction time scales of days to decades into the future. The driving forces that govern our environment are widely recognized, involving primarily weather and climate, patterns of land use and land cover, and resource use with its associated waste products. The importance of these driving forces has been demonstrated by a decade of research on greenhouse gas emissions, ozone depletion and deforestation, and through the birth of Earth System Science. But, there are also major challenges. We find the strongest intersection between human activity, environmental stresses, system interactions and human decision-making in regional analysis coupled to larger spatial scales. In addition, most regions are influenced by multiple-stresses. Multiple, cumulative, and interactive stresses are clearly the most difficult to understand and hence the most difficult to assess and to manage. Currently, we are incapable of addressing these issues in a truly integrated fashion at global scales. The lack of an ability to combine global and regional forcing and to assess the response of the system to multiple stresses at the spatial and temporal scales of interest to humans limits our ability to assess the impacts of specific human perturbations, to assess advantages and risks, and to enhance economic and societal well

  13. Regional compilation and analysis of aeromagnetic anomalies for the Transantarctic Mountains Ross Sea sector of the Antarctic

    Magnetic observations over the area of the Transantarctic Mountains (TAM) and the Ross Sea have been compiled into a digital database that furnishes a new regional scale view of the magnetic anomaly crustal field in this key sector of the Antarctic continent. This compilation is a component of the ongoing IAGA/SCAR Antarctic Digital Magnetic Anomaly Project (ADMAP). The aeromagnetic surveys total 115 000 line km, and are distributed across the Victoria Land sector of the TAM, the Ross Sea, and Marie Byrd Land. The magnetic campaigns were performed within the framework of the national and international Italian-German-US Antarctic research programs and conducted with differing specifications during nine field seasons from 1971 until 1997. Generally flight line spacing was less than 5 km while survey altitude varied from about 610 to 4000 m above sea level for barometric surveys and was equal to 305 m above topography for the single draped survey. Reprocessing included digitizing the old contour data, improved levelling by means of microlevelling in the frequency domain, and re-reduction to a common reference field based on the DGRF90 model. A multi-frequency grid procedure was then applied to obtain a coherent and merged total intensity magnetic anomaly map. The shaded relief map covers an area of approximately 380 000 km 2. This new compilation provides a regional image of the location and spatial extent of the Cenozoic alkaline magmatism related to the TAM-Ross Sea rift, Jurassic tholeiites, and crustal segments of the Early Palaeozoic magmatic arc. A linear, approximately 100-km wide and 600-km long Jurassic rift-like structure is newly identified. Magnetic fabric in the Ross Sea rift often matches seismically imaged Cenozoic fault arrays. Major buried onshore pre-rift fault zones, likely inherited from the Ross Orogen, are also delineated. These faults may have been reactivated as strike-slip belts that segmented the TAM into various crustal blocks.

  14. Microbial response to different phytoplankton-derived dissolved organic matter sources in the Ross Sea, Antarctica

    Western Antarctic shelves are highly productive regions that play an important role in global carbon and nitrogen cycles, specifically serving as a critical sink for carbon dioxide. Fixed carbon is stored within the phytoplankton cell as particulate organic matter or released into the surrounding water as dissolved organic matter (DOM). These phytoplankton-derived sources of organic matter support higher trophic levels as well as heterotrophic bacterial growth and respiration. The composition of the phytoplankton-derived organic matter is a function of the taxa as well as the environmental conditions under which it is produced. Phytoplankton community composition within western Antarctic Seas changes throughout Austral spring and summer with early production dominated by ice algae, switching to pelagic diatoms and flagellates later in the season. The goal of this study was to compare the response of Ross Sea microbial communities to DOM produced by ice algae or late season diatoms, specifically recent isolates of Pseudo nitzschia obtained from the Ross Sea. During 5-day bioassay studies, exudates from a natural ice algal community and from Pseudo nitzschia sp. isolates were added to natural microbial communities collected from two different Ross Sea locations, an ice-edge and an ice-covered site. The bacterial response to the DOM additions was greatest in the ice-covered community with a 5 and 3-fold higher bacterial abundance in the ice algae DOM and Pseudo nitzschia DOM treatments, respectively, relative to the control. The ice edge bacterial community responded similarly to both sources with a 2-fold increase in bacterial abundance compared to the control. Unlike the bacterial response, there was little difference in chlorophyll a concentrations between treatments, indicating that phytoplankton growth was not stimulated or inhibited by our additions.

    Human impact on the planet is causing a set of global environmental problems that threaten the wellbeing of current and future generations. Examples of these environmental problems include climate change, decline of biodiversity, alteration of biogeochemical cycles, ocean acidification, etc. These environmental Global Challenges (GCs) are transnational and complex, combining elements of both natural and social factors. Providing solutions for these challenges can be significantly enhanced through the collaboration of various related institutions, governments and stakeholders. A deeper understanding of the causes and consequences of GCs, as well as the processes which control them is required. Environmental Research Infrastructures (DANUBIUS-RI) are key players in this learning process. Covering many fields of research, it is through RIs collaboration that GCs can be more fully addressed. However, the collaboration among environmental RIs is still limited nationally as well as internationally. Although contact is encouraged and interactions are common practice, there are few cases where RI managers initiate and foster transnational collaborations in order to address specific problems. The COOP+ project aims to explore and strengthen cooperation among global RIs by bringing various RIs together and working on the identification of requirements, strengths, knowledge gaps and other relevant items in regard to the selected GCs. For this purpose, 13 GCs have been selected: coral bleaching, marine debris, noise impact on marine fauna, Arctic sea ice melting, pollinators decline, threatened species, agriculture pollutants, nitrogen cycle, carbon and GHG, geohazards and extreme events, estuaries, global urbanization process, and ozone depletion. These GCs are being analysed and described by multidisciplinary teams of experts composed of scientists, RIs operators and other stakeholders. This assessment will derive a list of tasks and requirements to be fulfilled by the

    The presence of overpopulation or unsustainable population growth may place pressure on the food and water supplies of countries in sensitive areas of the world. Severe air or water pollution may place additional pressure on these resources. These pressures may generate both internal and international conflict in these areas as nations struggle to provide for their citizens. Such conflicts may result in United States intervention, either unilaterally, or through the United Nations. Therefore, it is in the interests of the United States to identify potential areas of conflict in order to properly train and allocate forces. The purpose of this research is to forecast the probability of conflict in a nation as a function of it s environmental conditions. Probit, logit and ordered probit models are employed to forecast the probability of a given level of conflict. Data from 95 countries are used to estimate the models. Probability forecasts are generated for these 95 nations. Out-of sample forecasts are generated for an additional 22 nations. These probabilities are then used to rank nations from highest probability of conflict to lowest. The results indicate that the dependence of a nation`s economy on agriculture, the rate of deforestation, and the population density are important variables in forecasting the probability and level of conflict. These results indicate that environmental variables do play a role in generating or exacerbating conflict. It is unclear that the United States military has any direct role in mitigating the environmental conditions that may generate conflict. A more important role for the military is to aid in data gathering to generate better forecasts so that the troops are adequntely prepared when conflicts arises.

    This notice announces BPA`S`s decision to fund the Oregon Department of Fish and Wildlife (ODFW), the Washington Department of Fish and Wildlife (WDFW), and the Clatsop Economic Development Committee for the Lower Columbia River Terminal Fisheries Research Project (Project). The Project will continue the testing of various species/stocks, rearing regimes, and harvest options for terminal fisheries, as a means to increase lower river sport and commercial harvest of hatchery fish, while providing both greater protection of weaker wild stocks and increasing the return of upriver salmon runs to potential Zone 6 Treaty fisheries. The Project involves relocating hatchery smolts to new, additional pen locations in three bays/sloughs in the lower Columbia River along both the Oregon and Washington sides. The sites are Blind Slough and Tongue Point in Clatsop County, Oregon, and Grays Bay/Deep River, Wahkiakum County, Washington. The smolts will be acclimated for various lengths of time in the net pens and released from these sites. The Project will expand upon an existing terminal fisheries project in Youngs Bay, Oregon. The Project may be expanded to other sites in the future, depending on the results of this initial expansion. BPA`S has determined the project is not a major Federal action significantly affecting the quality of the human environment, within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an environmental impact statement is not required, and BPA`S is issuing this FONSI.

    The Inhalation Toxicology Research Institute (ITRI) was constructed in 1960 with the initial purpose of studying human health hazards of inhaling airborne radioactive fission products; its scope was broadened to cover other airborne materials. ITRI has in place an extensive radiological and nonradiological environmental monitoring program which monitors air emissions, groundwater, soil and ambient air around the facility. ITRI is in compliance with air quality and hazardous waste regulations; however, sewage lagoons remain from previous operations. Remediation activities have been begun or are scheduled to begin on these lagoons and on low-level radioactive liquid waste evaporation ponds. Except for the issues mentioned, ITRI is in compliance with all other federal, state, and local regulations.

    High latitudes are particularly interesting places to document natural climate variability. Sea ice is an important element in the climate system because it influences bottom water formation and ocean circulation and regulates the ocean-atmosphere heat exchange. Understanding climate and environmental changes through the reconstruction of past sea ice variability, atmospheric circulation and oceanographic conditions in the Southern Ocean could represent one of the most important keys to predict with confidence future climate changes on global scale. In fact, the oceanic area surrounding Antarctica represents the main source of bottom water formation affecting the global climate through the oceanic circulation. In this study, we present an interdisciplinary proxies analysis considering marine and ice core records, as part of the ESF PolarCLIMATE HOLOCLIP (Holocene climate variability at high-southern latitudes: an integrated perspective) project, to document sea ice variability in the Ross Sea continental shelf area. Diatom assemblages from three sediment cores located in the north-western Ross Sea (Joides Basin, Cape Hallett and Wood Bay) have been studied and the sea salt Na+ (a potential proxy of sea ice) records from two ice core sites (Taylor Dome and Talos Dome) facing the Ross Sea area have been considered. The significant positive correlations among the sea ice diatom Fragilariopsis curta relative abundance and sea salt Na+ records from Talos Dome and Taylor Dome ice cores, suggest that sea salt Na+ could be used as a proxy for sea ice extent and/or duration in the Ross Sea area. These preliminary results look as a positive premise in view of integrating proxies from different realms (marine and glacial) in order to achieve a more complete view of the climate and environmental changes occurring during the Holocene. The combination of geological and glacial records will greatly improve our knowledge on paleo sea ice dynamics.

    A significant portion of the research undertaken at Pacific Northwest Laboratory (PNL) is focused on the strategic programs of the US Department of Energy`s (DOE) Office of Health and Environmental Research (OHER). These programs, which include Environmental Processes (Subsurface Science, Ecosystem Function and Response, and Atmospheric Chemistry), Global Change (Climate Change, Environmental Vulnerability, and Integrated Assessments), Biotechnology (Human Genome and Structural Biology), and Health (Health Effects and Medical Applications), have been established by OHER to support DOE business areas in science and technology and environmental quality. PNL uses a set of critical capabilities based on the Laboratory`s research facilities and the scientific and technological expertise of its staff to help OHER achieve its programmatic research goals. Integration of these capabilities across the Laboratory enables PNL to assemble multidisciplinary research teams that are highly effective in addressing the complex scientific and technical issues associated with OHER-sponsored research. PNL research efforts increasingly are focused on complex environmental and health problems that require multidisciplinary teams to address the multitude of time and spatial scales found in health and environmental research. PNL is currently engaged in research in the following areas for these OHER Divisions: Environmental Sciences -- atmospheric radiation monitoring, climate modeling, carbon cycle, atmospheric chemistry, ecological research, subsurface sciences, bioremediation, and environmental molecular sciences; Health Effects and Life Sciences -- cell/molecular biology, and biotechnology; Medical Applications and Biophysical Research -- analytical technology, and radiological and chemical physics.

  13. Tectonic and Geomporphic Overview of the Ross Embayment Extensional Province

    NASA Astrophysics Data System (ADS)

    Wilson, D. S.

    2016-12-01

    The Ross Embayment is one of the lowest-standing continental regions on Earth. In essentially all places where basement topography has been mapped, the morphology is horst and graben. Several authors have suggested that the low topography is recent, with the area having been an orogenic highland in the Cretaceous. The tectonic extension driving the transition from high topography to low topography may have been as much as 500 km, with stretching factors of 2-3 over wide areas. Timing of the extension is incompletely known, but may have spanned most of the interval from 100 to 25 Ma. An analogy between the Ross Embayment and the North American Basin and Range province has often been suggested, and the case for that analogy has been growing. North American orogenic topography was probably highest 50 Ma, and margin-normal extension has been of the order of 200 km, and is ongoing. The Transantarctic Mountains bordering the Ross Embayment may share elements of their formation with the Wasatch Mountains of Utah and other parts of the eastern boundary of the Basin and Range. Glacial erosion and deposition have played a huge role in the geomorphic history of the Ross Embayment. The source region for the major ice streams, now well below sea level even after accounting for removal of the present ice load, restores with confidence to above sea level in the Eocene after accounting for the effects of 2 km of erosion and of thermal subsidence. The scale of these topographic changes is large enough that they need to be considered in detailed simulations of past climates, especially the initiation of the Antarctic ice sheets. Under generous interpretations of early Cenozoic tectonic extension in the Ross Embayment, the Late Cretaceous ancestral Transantarctic Mountains may have been high enough to host short-lived ice caps inferred from global sea level and oxygen-isotope records.

    The one-year anniversary is a critical milestone for a new journal. At that point there are enough articles published to begin to define the scope and readership, yet generally not enough of a track-record for the full community to regard the new entrant as a fixture and a source of 'must read' material. Environmental Research Letters (ERL) has set itself a particularly large and interesting challenge: to help connect the vast community of environmental researchers, practitioners, activists, and interested informed observers. ERL and its partner online resource base and community website, environmentalresearchweb, fills a major void: a single locus for rapid publication of peer-reviewed and highly interdisciplinary material spanning literally every aspect of environmental research and thought. The wide range of material that falls squarely into the purview of ERL—from restoration ecology to global change science and politics, to toxicology and environmental justice, to environmental and social impacts of energy conversion—illustrate just how diverse a 'community' we hope to serve. Thanks to an exceptional editorial staff and board, and a diverse range of fascinating contributed papers, ERL is off to a particularly fast start. ERL has both a small advisory board and a larger editorial board. The board serves several functions, beginning with the traditional one of taking the lead on reviews of papers in such a dizzying array of areas. This task alone is a challenge because of the commitment ERL has made to exceptionally rapid publication: a goal of 90 days from submission to online publication for accepted papers. This goal, which we have generally met, includes the publication of complementary (but not always complimentary) 500 1000 word commentaries on a number of papers. To accomplish this alone the editorial board, and the reviewers, have been heroic, and deserve a huge round of applause. IOP Publishing too, has been truly wonderful in making this happen

    Although decapod crustaceans are widespread in the oceans, only Natantia (shrimps) are common in the Antarctic. Because remoteness, depth and ice cover restrict sampling in the South Ocean, species distribution modelling is a useful tool for evaluating distributions. We used physical specimen and towed camera data to describe the diversity and distribution of shrimps in the Ross Sea region of Antarctica. Eight shrimp species were recorded: Chorismus antarcticus; Notocrangon antarcticus; Nematocarcinus lanceopes; Dendrobranchiata; Pasiphaea scotiae; Pasiphaea cf. ledoyeri; Petalidium sp., and a new species of Lebbeus. For the two most common species, N. antarcticus and N. lanceopes, we used maximum entropy modelling, based on records of 60 specimens and over 1130 observations across 23 sites in depths from 269 m to 3433 m, to predict distributions in relation to environmental variables. Two independent sets of environmental data layers at 0.05° and 0.5° resolution respectively, showed how spatial resolution affected the model. Chorismus antarcticus and N. antarcticus were found only on the continental shelf and upper slopes, while N. lanceopes, Lebbeus n. sp., Dendrobranchiata, Petalidium sp., Pasiphaea cf. ledoyeri, and Pasiphaea scotiae were found on the slopes, seamounts and abyssal plain. The environmental variables that contributed most to models for N. antarcticus were depth, chlorophyll-a concentration, temperature, and salinity, and for N. lanceopes were depth, ice concentration, seabed slope/rugosity, and temperature. The relative ranking, but not the composition of these variables changed in models using different spatial resolutions, and the predicted extent of suitable habitat was smaller in models using the finer-scale environmental layers. Our modelling indicated that shrimps were widespread throughout the Ross Sea region and were thus likely to play important functional role in the ecosystem, and that the spatial resolution of data needs to be

    The Open Support Platform for Environmental Research (OSPER) has been launched to take forward key data management components developed under the Swiss Experiment platform project to achieve improved usability and a wider scope. With this project, we aim to connect users to data and their context, an area identified during SwissEx as having the greatest potential impact on the research community. OSPER has a clear focus on providing the technology for data storage, management and exploitation with a special focus on data interoperability and documentation. In this presentation, we will demonstrate the key aims of OSPER for the period 2012 - 2015. Inheriting the basic SwissEx functionality, OSPER provides an excellent method of making data accessible via their metadata. One of the biggest differences between the OSPER infrastructure and other data platforms is the level of interaction that one can have with the data and the level of integration with the analysis tools used in science. We wish to capitalise on this advantage by increasing this integration and working with environmental research projects to develop the tools that make a difference to their daily research. The new data infrastructure will serve the following purposes: ● Open documentation, archiving and discovery of datasets. ● Facilitation of data sharing and collaboration (especially inter-disciplinary) with data owner controlled access rights, particularly concentrating on providing as much contextual information as possible. ● Improvements in ease of data access and combination of data sources. ● Tools for data visualisation and statistical and numerical data analysis with a focus on spatial data and trends. Key areas identified for development during OSPER are: ● New infrastructure and content for current WebGIS-based data visualisation system to create a publicly available platform. ● Provision of data in standard formats using standard methods as well as the consumption of such data

    2014-12-01

    This presentation discusses two ongoing interdisciplinary case studies that are using qualitative research to design and enhance environmental communication and science products for outreach and decision making purposes. Both cases demonstrate the viability and practical value of qualitative social science methodology, specifically focus group interviews, to better understand the viewpoints of target audiences, improve deliverables, and support project goals. The first case is a NOAA-funded project to conduct process-based modeling to project impact from climate change in general and sea level rise in particular to the natural and built environment. The project spans the Mississippi, Alabama, and Florida Panhandle coasts with concentration on the three National Estuarine Research Reserves. As part of the broader project, four annual focus groups were conducted with a purposive sample of coastal resource managers to capture their perspectives and suggestions to better meet their informational and operational needs. The second case is a Florida Sea Grant-funded project that is developing, implementing, and testing a cohesive outreach campaign to promote voluntary careful and responsible recreational boating to help protect sensitive marine life and habitats (especially seagrasses and oyster reefs) in the Mosquito Lagoon. Six focus groups were conducted with a purposive sample of the target audience of boaters to gain insights, feedback, and ideas on the direction of the campaign and design of the messages and products. The campaign materials created include a branded website, Facebook page, mobile app, information packets, brochures, pledge forms, and promotional items. A comparison of these two case studies will be provided and will explain how the qualitative findings were/are being implemented to tailor and refine the respective communication strategies and techniques including the emerging outreach products. The resulting outcomes are messages and tools that are

  8. Soil micromorphology, geochemistry and microbiology at two sites on James Ross Island, Maritime Antarctica

    Referring to the fundamental question in ecosystem research, how biotic and abiotic processes interact, only a few studies exist for polar regions that integrate microbiological and soil scientific studies . Soils comprise the complex structure and environment that fosters water storage and nutrient cycling determined by its unique chemical, physical and biological properties with respect to the specific climate and parent material. In the extreme environment of Antarctica, soil biological processes are primarily controlled by microbial communities (Bacteria, Archaea and Fungi), and thus microbiota may also determine soils chemical and physical properties in a landscape lacking higher plants at an average air temperature below 0°C. James Ross Island, Maritime Antarctica, offers a pristine laboratory and an exceptional opportunity to study pedogenesis without the influence of vascular plants and burrowing animals. We analysed micromorphological features, chemical and microbiological measures at two sites on James Ross Island (Brandy Bay and St. Martha Cove) with similar substrates (mostly fine-grained calcareous sandstones and siltstones of the Alpha Member of the Santa Martha Formation with varying amounts of conglomerates and mudstones) at similar topographic positions (small plateaus at similar elevation (80m a.s.l.)). The sites represent luv- and leeward conditions with respect to the main southwesterly winds. The climate on James Ross Island is to be described as semi-arid polar-continental, which is in clear contrast to the Southern Shetlands (e.g. King George Island) north of the Antarctic Peninsula. We will present first results of soil physical (bulk density, soil moisture and grains size distribution), pedochemical (SOC, total N and S, pH, CECeff, and pedogenic oxides) micromorphological and microbial analyses (Microbial DNA content, microbial abundances).

    A sediment core, collected from the western part of the continental slope of the Ross Sea at 2380 m water depth, records events of the last two climatic cycles (250 kyr). A 230Th ex-based chronology was obtained and boundaries of the isotope stages were set assuming that biological productivity was enhanced during periods of less ice cover. Then, 230Th ex0, organic carbon, biogenic silica and biogenic Ba distributions were compared to the glacial-interglacial stage boundaries and corresponding ages of the δ 18O record of Martinson et al. [Martinson, D.G., Pisias, N.G., Hays, J.D., Imbrie, J., Moore, T.C., Jr., Shackleton, N.J, 1987. Age dating and the orbital theory of the ice ages: development of a high-resolution 0 to 300,000-year chronostratigraphy. Quaternary Research, 27: 1-29]. Sediment accumulation rates ranged between 1.2 cm kyr -1 in the isotope stage 6 and 3.8 cm kyr -1 during the Holocene. Variations in the concentrations and fluxes of organic carbon, biogenic Ba, biogenic silica and Mn gave information on palaeoclimate changes. Processes of sediment redistribution in the Ross Sea margin were enlightened from a comparison of the measured and expected fluxes of 230Th ex. Calculation of the focusing-corrected accumulation rates of biogenic Ba enabled us to evaluate the export palaeoproductivity. Corrected accumulation rates of biogenic components and calculated palaeoproductivities were low, compared to the Antarctic Polar Front in the Atlantic sector, throughout the last two climatic cycles. Glacial-interglacial changes of sea ice cover and ventilation of the Ross Sea were probably major causes of variations in biogenic particle flux and distribution of redox-sensitive elements within the sediment column.

    The Closed Environmental Research Chamber (CERC) at the NASA Ames Research Center was created to investigate both components and complete systems for life support of advanced space exploration missions. This facility includes a Main Chamber, an Airlock, a Sample Transfer Lock, a Vacuum System, an Air Recompression System, a dedicated control room and a pit area for housing supporting and environmental control systems. The Main Chamber provides 310 sq ft of internal working/living space on two levels. It is planned that the CERC will be a human-rated facility for habitation simulation under mass balance closure conditions. The internal pressure will be variable over the range of 14.7 psia to 5 psia with accompanying capability for variation in atmosphere composition to maintain the oxygen partial pressure at 160 mm Hg. The CERC will be provided with a core set of primary life support subsystems for temperature and humidity control, C02 removal and trace contaminant control. Interfacing with external life support technology test bds with be provided, along with connection to centralized, microprocessor-based data acquisition and control systems. This paper will discuss the current status of the CERC facility and show how it is being used to address the advanced technology requirements necessary to implement an integrated working and living environment for a planetary habitat. In particular, it will be shown how the CERC, along with a human-powered centrifuge, a planetary terrain simulator and advanced displays and a virtual reality capability will work together to develop and demonstration applicable technologies for future planetary habitats. Artificial intelligence and expert system programming techniques will be used extensively to provide an automated environment for a 4-person crew. There will be several robotic mechanisms performing exploration tasks external to the habitat that will be controlled through the virtual environment to provide representative

    Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month involved continued investigations into the Clear Liquor Scrubbing Process for the production of Anhydrous Calcium Sulfate (Anhydrite). The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the Carbon Injection System (the Pulse-jet Fabric Filter) remained idle this month in a cold-standby mode and were inspected regularly. From May 3-18, the NYSEG Kintigh Station and the ECTC were off-line for a two-week scheduled Station outage. During the ECTC outage, the major systems of the Center were inspected, and several preventive maintenance activities were completed. A listing of the major O&M outage activities completed during this period is presented in the Pilot/Mini-Pilot section of this report. In May 1997, an extension to the Anhydrite Production test block was started following the NYSEG outage. The extension to the Anhydrite Production test block is being funded by the Electric Power Research Institute (EPRI) after promising results from the original test program. Both EPRI and the Department of Energy (DOE) funded the original test program as part of the DOE`s Advanced Power Systems Program, whose mission is to accelerate the commercialization of affordable, high- efficiency, low-emission, coal-fueled electric generating technologies. While the pilot portion of the Anhydrite project was conducted on the 4.0 MW wet FGD pilot unit at EPRI`s Environmental Control Technology Center (ECTC) in Barker, New York, the extension mainly used the 0.4 MW Mini-Pilot wet FGD unit to reduce operating costs. The project is designed to develop an advanced FGD process that produces a useable byproduct, anhydrite (anhydrous calcium sulfate). The original CLS/Anhydrite process included three steps: chloride removal, clear liquor scrubbing, and anhydrite production. The final step in the process involved

    A modified version of the dynamic 3-dimensional mesoscale Coupled Ice, Atmosphere, and Ocean model (CIAO) of the Ross Sea ecosystem has been used to simulate the impact of environmental perturbations upon primary production and biogenic CO2 uptake. The Ross Sea supports two taxonomically, and spatially distinct phytoplankton populations; the haptophyte Phaeocystis antarctica and diatoms. Nutrient utilization ratios predict that P. antarctica and diatoms will be driven to nitrate and phosphate limitation, respectively. Model and field data have confirmed that the Ross Sea is iron limited with only two-thirds of the macronutrients consumed by the phytoplankton by the end of the growing season. In this study, the CIAO model was improved to simulate a third macronutrient (phosphate), dissolved organic carbon, air-sea gas exchange, and the carbonate system. This enabled us to effectively model pCO2 and subsequently oceanic CO2 uptake via gas exchange, allowing investigations into the affect of alleviating iron limitation on both pCO2 and nutrient drawdown.

    Information on health parameters, such as antibody prevalences and serum chemistry that can reveal exposure to pathogens, disease, and abnormal physiologic conditions, is scarce for Antarctic seal species. Serum samples from Antarctic fur seals (Arctocephalus gazella, n=88) from Bouvetøya (2000-2001 and 2001-2002), and from Weddell seals (Leptonychotes weddellii, n=20), Ross seals (Ommatophoca rossii, n=20), and crabeater seals (Lobodon carcinophagus, n=9) from the pack-ice off Queen Maud Land, Antarctica (2001) were analyzed for enzyme activity, and concentrations of protein, metabolites, minerals, and cortisol. Adult Antarctic fur seal males had elevated levels of total protein (range 64-99 g/l) compared to adult females and pups (range 52-79 g/l). Antarctic fur seals had higher enzyme activities of creatine kinase, lactate dehydrogenase, and amylase, compared to Weddell, Ross, and crabeater seals. Antibodies against Brucella spp. were detected in Weddell seals (37%), Ross seals (5%), and crabeater seals (11%), but not in Antarctic fur seals. Antibodies against phocine herpesvirus 1 were detected in all species examined (Antarctic fur seals, 58%; Weddell seals, 100%; Ross seals, 15%; and crabeater seals, 44%). No antibodies against Trichinella spp., Toxoplasma, or phocine distemper virus (PDV) were detected (Antarctic fur seals were not tested for PDV antibodies). Antarctic seals are challenged by reduced sea ice and increasing temperatures due to climate change, and increased anthropogenic activity can introduce new pathogens to these vulnerable ecosystems and represent a threat for these animals. Our data provide a baseline for future monitoring of health parameters of these Antarctic seal species, for tracking the impact of environmental, climatic, and anthropogenic changes in Antarctica over time.

    Analysed in the article are the results of the Ross procedure in patients presenting with dilatation of the ascending portion of the aorta. A combination of aortic valve defects with dilatation of the ascending aorta of more than 45 mm supposes simultaneous prosthetic repair of the aortic valve and ascending aorta. The most common surgical procedure remains the Bentall-DeBono operation whose main disadvantage is associated with implantation of a mechanical prosthesis and the necessity of lifelong anticoagulant therapy. An alternative method is the Ross procedure demonstrating low risk of thromboembolic complications and freedom from anticoagulant therapy. Over the period from 2002 to April 2015, specialists of the Novosibirsk Scientific Research Institute of Circulatory Pathology named after Academician E.N. Meshalkin carried out a total of 162 Ross procedures in patients presenting with accompanying dilatation of the ascending aorta (more than 45 mm). The mean diameter of the aorta at the level of Valsalva sinuses amounted to 45.6±8.6 mm, with that of the ascending aortic portion equalling 53.4±7.8 mm. The technique of total replacement of the aortic root was used in all cases. When the aneurysm extended to distal portions of the ascending aorta, additionally performed were the following procedures: in 24 patients--reduction aortoplasty, in 6 patients--replacement of the resected aorta with an insert from xenopericardium, and in 2 patients with a vascular graft. The average duration of follow up amounted to 40.1±21.6 months. Ten patients were subjected to repeat operations for autograft dysfunction. There were no reoperations on the ascending portion of the aorta. The regression analysis revealed that predictors of the development of autograft dysfunction were the baseline dilatation of the fibrous ring (FR) of the aortic valve of more than 27 mm (p=0.04) and uncorrected arterial hypertension in the postoperative period (p=0.03). In the group of patients with
