Integrating research and management to conserve wildfowl (Anatidae) and wetlands in the Mississippi Alluvial Valley, U.S.A Integrating research and management to conserve wildfowl (Anatidae) and wetlands in the Mississippi Alluvial Valley, U.S.A
Efforts to conserve winter habitat for wildfowl, Anatidae, in the alluvial valley of the lower Mississippi River, U.S.A., are directed by the Lower Mississippi Valley (LMV) Joint Venture of the North American Waterfowl Management Plan (NA WMP). The Joint Venture is based on a biological framework developed through cooperative planning by wildfowl researchers and managers. Important...

Seismic reflection profile of the Blake Ridge near sites 994, 995, and 997 Seismic reflection profile of the Blake Ridge near sites 994, 995, and 997
Seismic reflection profiles near Sites 994, 995, and 997 were collected with seismic sources that provide maximum resolution with adequate power to image the zone of gas hydrate stability and the region direction beneath it. The overall structure of the sediment drift deposit that constitutes the Blake Ridge consists of southwestward-dipping strata. These strata are approximately...

Radon in ground water of the lower Susquehanna and Potomac River basins Radon in ground water of the lower Susquehanna and Potomac River basins
Ground-water samples collected from 267 wells were analyzed for radon as part of a water-quality reconnaissance of subunits of the Lower Susquehanna and Potomac River Basins conducted by the United States Geological Survey (USGS) as part of the National Water-Quality Assessment (NAWQA) program. Radon is a product of the radioactive decay of uranium. Airborne radon has been cited by the...

Hydrogeology and simulated ground-water flow through the unconsolidated aquifers of northeastern St. Joseph County, Indiana Hydrogeology and simulated ground-water flow through the unconsolidated aquifers of northeastern St. Joseph County, Indiana
The U.S. Geological Survey investigated ground-water resources of northeastern St. Joseph County, Indiana, during 1990-93. The investigation included field measurements of water levels and numerical models of ground-water flow. This report documents results of that work and includes descriptions of (1) hydrogeologic framework, (2) water levels, (3) model sensitivity to variations in...

Altitude and configuration of the potentiometric surface, December 6, 1994, in the carbonate rocks in part of East Whiteland and Charlestown townships, Chester County, Pennsylvania Altitude and configuration of the potentiometric surface, December 6, 1994, in the carbonate rocks in part of East Whiteland and Charlestown townships, Chester County, Pennsylvania
A map showing ground-water levels in the carbonate rocks in part of East Whiteland and Charlestown Townships, Chester County, Pennsylvania, was constructed from water levels measured in 64 wells on December 6, 1994. Observed water-level altitudes range from 226 feet above sea level near Morehall Road to 400 feet above sea level near State Route 401 in East Whiteland Township.
