Data

This USGS data release contains station and laboratory method information and geospatial information, as well as concentration results for inorganic and organic compounds and bioluminescent yeast estrogen screen and transgenic zebrafish embryo estrogren bioassay, analyzed at 38 sites in 25 states as part of the Chemical Mixtures and Environmental Effects Pilot Study, 2012-2014.

The effects of climate change have the potential to impact slope stability. Negative impacts are expected to be greatest at high northerly latitudes where degradation of permafrost in rock and soil, debuttressing of slopes as a result of glacial retreat, and changes in ocean ice-cover are likely to increase the susceptibility of slopes to landslides. In the United States, the greatest increases in

An improved understanding of groundwater flow and radionuclide migration downgradient from underground nuclear-testing areas at Pahute Mesa, Nevada National Security Site, requires accurate subsurface hydraulic characterization. To improve conceptual models of flow and transport in the complex hydrogeologic system beneath Pahute Mesa, the U.S. Geological Survey characterized bulk hydraulic propert

This dataset contains water surface elevations for the wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota, 1979 through 2015.

This dataset contains the specific conductance values for all wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota, 1992 through 2015.

The National Water Quality Network (NWQN) for Rivers and Streams includes 113 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program (NWQP). The NWQN represents the consolidation of four historical national networks: the USGS National Water-Quality Assessment (NAWQA) Project, the USGS National Stream Quality Accounting Network (NASQAN), t

In the face of sea level rise and as climate change conditions increase the frequency and intensity of topical storms along the north-Atlantic Coast, coastal areas will become increasingly vulnerable to storm damage, and the decline of already-threatened species could be exacerbated. Predictions about response of coastal birds to efrfect of hurricane will b eessential for anticipating and counter

Surface water, sediment, and fish from Biscayne Bay, coastal wetlands adjacent to Biscayne Bay, and canals discharging into Biscayne Bay were sampled for determination of baseline contamination in Biscayne National Park. The number of contaminants detected in canal waters was greater during the wet season relative to the dry season, a relation not evident in Biscayne Bay or wetland waters. Estroge

This data release includes the airborne magnetic survey data collected from the Manchester region of Iowa. The Mineral Resources Program of the U.S. Geological Survey is tasked with understanding the nation's mineral resources. Precambrian rocks concealed under Paleozoic sedimentary rocks in northeast Iowa are poorly mapped and understood. Detailed high-resolution airborne magnetic surveys, ground

This dataset includes the magnetotelluric (MT) sounding data collected in 2006 in the Southern San Luis Valley, Colorado. The U.S. Geological Survey conducted a series of multidisciplinary studies, including MT surveys, in the San Luis Valley to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers o
