Ecological community datasets used to evaluate the presence of trends in ecological communities in selected rivers and streams across the United States, 1992–2017 Ecological community datasets used to evaluate the presence of trends in ecological communities in selected rivers and streams across the United States, 1992–2017
In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water Quality Program. One of the major goals of the NAWQA project is to determine how water quality and ecological conditions change over time. To support that goal, long-term consistent and...
Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock for Geohydrology and Water Quality of the Stratified-Drift Aquifer in West Branch Cayuga Inlet and Fish Kill Valleys, Town of Newfield, Tompkins County, New York, July 2011 - November 2016 Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock for Geohydrology and Water Quality of the Stratified-Drift Aquifer in West Branch Cayuga Inlet and Fish Kill Valleys, Town of Newfield, Tompkins County, New York, July 2011 - November 2016
From July 2011 to November 2016, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, collected horizontal-to-vertical seismic surveys at 58 locations in the West Branch Cayuga Inlet and Fish Kill valleys to help determine thickness of unconsolidated deposits and depth to bedrock. The HVSR technique, commonly referred to as the...
Geospatial datasets for the geohydrology and water quality of the stratified-drift aquifers in West Branch Cayuga Inlet/Fish Kill aquifers in Newfield, Tompkins County, New York Geospatial datasets for the geohydrology and water quality of the stratified-drift aquifers in West Branch Cayuga Inlet/Fish Kill aquifers in Newfield, Tompkins County, New York
In 2011, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, began a study of the stratified-drift aquifers in the West Branch Cayuga Inlet and Fish Kill valleys in the Town of Newfield, Tompkins County, New York. The objective of this study was to characterize the hydrogeology and water quality of the stratified-drift...
Avoidance behavior of cold-, cool-, and warmwater fish exposed to Zequanox in a two-choice preference chamber, data release Avoidance behavior of cold-, cool-, and warmwater fish exposed to Zequanox in a two-choice preference chamber, data release
Zequanox® is an EPA-registered biopesticide for controlling populations of dreissenid mussels (zebra and quagga mussels). Zequanox has demonstrated selective toxicity toward dreissenid mussels; however, a recent laboratory study indicated the potential for Zequanox to impact a non-target salmonid species. We assessed the potential exposure risk by observing the avoidance behavior of two
Assessments of the binary mixtures of four toxicants on Zebra Mussel (Dreissena polymorpha) mortality, data release Assessments of the binary mixtures of four toxicants on Zebra Mussel (Dreissena polymorpha) mortality, data release
This dataset captures the Zebra Mussel dose-response to four independent toxicants and each binary mixture of those toxicants. Toxicants included EarthTec QZ, Clam-Trol CT-2 (syn. Spectrus CT1300), niclosamide, and potassium chloride. Each dose of toxicant was verified with either ICP-OES or UHPLC, depending on analyte, and comparison to a standard curve. Mortality was tabulated for each
Geochemical data from batch experiments to test mobility of trace elements downgradient from breccia-pipe uranium deposits Geochemical data from batch experiments to test mobility of trace elements downgradient from breccia-pipe uranium deposits
This data release includes solid and aqueous chemical data related to a set of sequential laboratory batch experiments conducted to test and simulate the mobility of trace elements as natural waters contact ore from breccia pipe uranium (BPU) deposits located in northern Arizona. The experiments made use of aquifer-related, sedimentary rocks collected specifically for this study and...
