Use of the USDA Forest Service Geographic Information System for determining cover type use by white-tailed deer
Christopher S. DePerno, Jonathan A. Jenks, Steven L. Griffin, Robert W. Klaver
2001, Conference Paper, Proceedings of the South Dakota academy of science, vol. 80
Cover type use by white-tailed deer (Odocoileus virginianus dacotensis) in the central Black Hills of South Dakota was compared to the United States Department of Agriculture (USDA) Forest Service digital data using a Geographic Information System (GIS). Cover types were determined from observations of radiocollared deer and random locations and...

Transboundary movement of airborne pollutants — A methodology for integrating spaceborne images and ground based data
Jill Engel-Cox, Thomas P. DeFelice, Stefan Falk
2001, Report
The availability of relevant and accurate environmental information is essential for environmental policy-makers. Recent improvements in satellite remote sensing technologies, groundbased monitors, and data access have resulted in the ability to observe and assess major atmospheric and ecological events around the world on a timely basis Each of these monitoring...

Occurrence and distribution of contaminants in bottom sediment and water of the Barron River Canal, Big Cypress National Preserve, Florida
Ronald L. Miller, Benjamin F. McPherson
2001, Florida Scientist (64) 1-19
Trace elements and organic contaminants in bottom-sediment samples collected from 10 sites on the Barron River Canal and from one site on the Turner River in October 1998 had patterns of distribution that indicated different sources. At some sites on the Barron River Canal, lead, copper, and zinc, normalized to...

Gas hydrate in seafloor sediments: Impact on future resources and drilling safety
William P. Dillon, Michael D. Max
2001, Conference Paper
Gas hydrate concentrates methane and sometimes other gases in its crystal lattice and this gas can be released intentionally creating a resource or escape accidentally forming a hazard. The densest accumulations of gas hydrate tend to occur at sites where the base of the gas hydrate stability zone (commonly the...
Sedimentary Carbon, Sulfur, and Iron Relationships in Modern and Ancient Diagenetic Environments of the Eel River Basin (U.S.A.)
C.K. Sommerfield, R.C. Aller, C.A. Nittrouer
2001, Journal of Sedimentary Research (71) 335-345
Depositional and diagenetic controls on the distributions of carbon, sulfur, and iron (C-S-Fe) in modern sediments and upper Pleistocene mudrocks of the Eel River Basin (ERB), northern California continental margin, were investigated using a combination of geochemical, radioisotopic, and sedimentological methods. A mass balance based on down-core profiles of porewater...

The South China Sea is poorly understood in terms of its marine biota, ecology and the human impacts upon it. What is known is most often contained in reports and workshop and conference documents that are not available to the wider scientific community. The South China Sea has an area...

Applications of satellite ocean color sensors for monitoring and predicting harmful algal blooms
Richard P. Stumpf
2001, Human and Ecological Risk Assessment (7) 1363-1368
The new satellite ocean color sensors offer a means of detecting and monitoring algal blooms in the ocean and coastal zone. Beginning with SeaWiFS (Sea Wide Field-of-view Sensor) in September 1997, these sensors provide coverage every 1 to 2 days with 1-km pixel view at nadir. Atmospheric correction algorithms designed...

Regulation of subcellular localization of the Aryl Hydrocarbon Receptor (AhR)
Cathy A. Richter, Donald E. Tillitt, Mark Hannink
2001, Archives of Biochemistry and Biophysics (389) 207-217
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that mediates the toxicity of dioxin and other xenobiotics. In the absence of exogenous ligand, AhR is cytosolic. We investigated how AhR is retained in the cytosol and how dioxin induces AhR to move to the nucleus. Disruption of nuclear...
Bayesian analysis of U.S. hurricane climate
James B. Elsner, Brian H. Bossak
2001, Journal of Climate (14) 4341-4350
Predictive climate distributions of U.S. landfalling hurricanes are estimated from observational records over the period 1851–2000. The approach is Bayesian, combining the reliable records of hurricane activity during the twentieth century with the less precise accounts of activity during the nineteenth century to produce a best estimate of the posterior...
Marine recreation and public health microbiology: Quest for the ideal indicator
Dale W. Griffin, Erin K. Lipp, Molly R. McLaughlin, Joan B. Rose
2001, BioScience (51) 817-825
Four-fifths of the population of the United States live in close proximity to the oceans or Great Lakes, and approximately 100 million Americans use the marine environment for recreation each year (Thurman 1994). Consequently, contamination of lakes, rivers, and coastal waters raises significant public health...
Effects of food stress on survival and reproductive performance of seabirds
John F. Piatt, Sasha Kitaysky
2001, Report
Traditional field methods of assessing effects of fluctuations in food supply on the survival and reproductive performance of seabirds may give equivocal results. In this project we applied an additional tool: The measure of stress hormones in free-ranging seabirds. Food stress can be quantified by measuring base levels of stress...

2001, Conference Paper, Planetary Mapping: ISPRS Working Group IV/9 Workshop Proceedings
The Magellan spacecraft went into Venus orbit in 1990 and by 1992 had made three complete cycles of polar orbits, each cycle covering the full range of longitudes. During this time the spacecraft obtained synthetic aperture radar (SAR) images of >96% of the planet at a resolution of 75 m/pixel....
