Fate of Airborne Contaminants in Okefenokee National Wildlife Refuge Fate of Airborne Contaminants in Okefenokee National Wildlife Refuge

Designation of Okefenokee National Wildlife Refuge as a Class I Air Quality Area (given the highest level of protection possible from air pollutants under the Clean Air Act Amendments of 1977) affords mandatory protection of the Refuge's airshed through the permit-review process for planned developments. Rainfall is the major source of water to the swamp, and potential impacts from...

The scientific bases for preservation of the Mariana crow The scientific bases for preservation of the Mariana crow

The Panel recently released the report and recommendations resulting from its work over the last six months. Although primarily focused on the Mariana Crow, the report highlights that this is a matter potentially far more serious than the preservation of the crow on Guam and Rota. The report includes major sections dealing with the need to intensify research and control activities on the...

Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change

Boreholes from Island Beach, Allaire, Atlantic City, and Mays Landing, NJ provide an excellent chronology of lower to middle Eocene passive margin sequences and allow analysis of long-term sea-level changes and sedimentation patterns. These New Jersey sequences are tied directly to the geomagnetic polarity time scale through magnetostratigraphy. Integrated stratigraphy (including

Initial results of high-resolution sea-floor mapping offshore of the New York - New Jersey metropolitan area using sidescan sonar Initial results of high-resolution sea-floor mapping offshore of the New York - New Jersey metropolitan area using sidescan sonar

High-resolution seismic, sidescan-sonar, multibeam bathymetry, and sediment sampling techniques were used to map the surficial geology and shallow subbottom stratigraphy of a segment of the inner shelf and nearshore region of New York-New Jersey metropolitan area. Preliminary analyses of these data provide a sedimentologic framework for addressing a wide range of science and management...

Lignin phenols in sediments of Lake Baikal, Siberia: Application to paleoenvironmental studies Lignin phenols in sediments of Lake Baikal, Siberia: Application to paleoenvironmental studies

Sediments from three cores obtained from distinct depositional environments in Lake Baikal, Siberia were analyzed for organic carbon, total nitrogen and lignin phenol concentration and composition. Results were used to examine changes in paleoenvironmental conditions during climatic cycles of the late Quaternary ( 125 ka). Average organic carbon, and total nitrogen concentrations, atomic...

Modeling gas transfer in a spray tower oxygen absorber Modeling gas transfer in a spray tower oxygen absorber

A computer model characterizing the performance of a spray tower oxygen absorption system was developed based on finite difference mass transfer calculations. Performance was assessed in terms of oxygen utilization, transfer efficiency, and economy. Pilot scale tests verified model assumptions and performance predictions. Simulation runs indicated spray tower head and oxygen feed...

Sediment transport pathway in the back of a nearly semienclosed subembayment of San Francisco Bay, California Sediment transport pathway in the back of a nearly semienclosed subembayment of San Francisco Bay, California

Time series measurements of current velocity, depth and suspended-solids concentration (SSC) were used to obtain suspended-solids fluxes (SSF) during the fall at central Honker Bay and Spoonbill Creek. A wind-induced shear stress increases SSF out of Honker Bay through Spoonbill Creek by combining two effects: (1) wind-wave resuspension of bed sediments, and (2) wind shear raises the...

The loss of hyperosmoregulatory ability in migrating juvenile American shad, Alosa sapidissima The loss of hyperosmoregulatory ability in migrating juvenile American shad, Alosa sapidissima

Investigations on juvenile American shad (Alosa sapidissima) revealed several physiological changes associated with downstream migration. Plasma chloride decreased 20% in wild juvenile shad during the autumn migration. Migrants had lower condition factor and hematocrit than non-migrant shad captured by beach seining. Gill Na + ,K + -ATPase activity of migrant shad was higher than non...

Anthropogenic molecular markers: Tools to identify the sources and transport pathways of pollutants Anthropogenic molecular markers: Tools to identify the sources and transport pathways of pollutants

The activities of modern civilization have released to the oceans a wide variety of both mobilized natural compounds and synthetic compounds not found prior to modern times. Many of these compounds provide a means of identifying sources of inputs and pathways of movement of chemicals through oceanic ecosystems and serve as molecular markers of human activities. A coastal ocean (Tokyo Bay...
