The Rybinsk Reservoir (Russia) is the largest artificial waterbody in Europe (4550 km2) and provides drinking water for population of the cities located along the coast line. Industrialization in Cherepovets at the northeastern portion of the reservoir, including one of the largest metallurgical facilities in Europe, has resulted in chemical contamination of the reservoir. The extent of

Information on growth during the larval and young-of-year life stages in natural river environments is generally lacking for most sturgeon species. In this study, methods for estimating ages and quantifying growth were developed for field-sampled larval and young-of-year shovelnose sturgeon Scaphirhynchus platorynchus in the upper Missouri River. First, growth was assessed by...

Since 1959, the U.S. Geological Survey has conducted a cooperative water resources program (CWP) with the City of Brunswick and Glynn County in the Brunswick, Georgia, area. Since the late 1950s, the salinity of ground water in the Upper Floridan aquifer near downtown Brunswick, Georgia, has been increasing, and its occurrence has been detected across an area of increasing size. Pumping...

The unusual characteristics of subterranean flow in karst aquifers allow for the transport of sediment. Kartst ground-water system are created by dissolution of the bedrock matrix coupled with structural and stratigraphic controls. As a result, high flow velocities, large-diameter openings, and turbulent flow, all necessary for the entrainment and transport of particles, are present—at...

In July of 2006, the U.S. Geological Survey (USGS) conducted a geophysical survey offshore of the Chandeleur Islands, Louisiana, as part of the USGS Barrier Island Coastal Monitoring project (BICM), which is part of a broader study focused on Subsidence and Coastal Change (SCC). This report serves as an archive of unprocessed digital Compressed High Intensity Radar Pulse (CHIRP) seismic...

A week after Hurricane Katrina made landfall in Louisiana, a collaboration among multiple organizations began building a database called the Geographic Information System for the Gulf, shortened to "GIS for the Gulf," to support the geospatial data needs of people in the hurricane-affected area. Data were gathered from diverse sources and entered into a consistent and standardized data...

The U.S. Geological Survey (USGS) assisted State and Federal agencies with humanitarian aid and geospatial analyses in support of search and rescue operations after Hurricanes Katrina and Rita.

The National Wetlands Research Center (NWRC) library is part of the U.S. Geological Survey (USGS) and is the only USGS library dedicated to wetland science. The mission of the NWRC library is to support the research and information needs of scientists, managers, and support personnel by providing a specialized, scientific collection of library materials and related information services...

Libraries are grouped into four major types: public, school, academic, and special. The U.S. Geological Survey's (USGS) National Wetlands Research Center (NWRC) library is classified as a special library because it is sponsored by the Federal government, and the collections focus on a specific subject. The NWRC library is the only USGS library dedicated to wetland science. Library...

Adult rare minnow (Gobiocypris rarus) were exposed to 0, 1, 5, and 25 ng/l (nominal concentrations) of 17α-ethynylestradiol (EE2) and 3, 10, and 30 μg/l (nominal concentrations) of 4-nonylphenol (NP) under flow-through conditions for a period of 28 d. Low mortality was observed at 5 and 25 ng/l EE2 and the growth of fish reduced significantly at 25 ng/l EE2 compared to controls. However...

A multiple-database approach that combined remotely sensed data from Radarsat-1 and Landsat Thematic Mapper Plus (ETM+) imagery was used to map Hurricane Katrinainduced flooding and to identify offshore oil slicks. Maps depicting the areal extent of flooding, oil slicks, and floating debris provide vital information to emergency managers for directing floodrelief efforts and the clean-up...

The flooding that ensued in the Greater New Orleans area after Hurricane Katrina left thousands of victims trapped and in need of emergency rescue. This paper describes the processing of raw 911-call data into search and rescue products used by emergency responders after the storm.
