Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Concentrations of environmental DNA (eDNA) during sockeye salmon spawning in 2016, Hansen Creek, Alaska, USA
This dataset contains environmental DNA (eDNA) concentrations and spawning adult abundances for sockeye salmon (Oncorhynchus nerka) in Hansen Creek, a small tributary in the Wood River watershed, southeast Alaska, USA. We took temporally- and spatially-replicated eDNA samples during the spawning period (mid-July through August), along with fish counts (live, naturally dead, and killed), dissolved
2010/11 Level 3 Aquatic Areas - Upper Mississippi River System
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS). Aerial images of Pools 3-13 Upper Mississippi River System and Pools, Alton-Marseilles, Illinois River were collected in color infrared (CIR) in August of 2010 at 8/pixel and 16/pixel respectively using a mapping-grade Appl

Zooplankton, phytoplankton, and water-quality data for Nolin Lake near Finney, Kentucky during a midwinter swarm by the exotic cladoceran Daphnia lumholtzi, 2016-2017
This U.S. Geological Survey Data Release provides data collected from Nolin Lake Kentucky, during 2016 to 2017. Two types of data are reported: zooplankton and phytoplankton data are raw calculated values not rounded to USGS significant figures and continuous water-quality data collected with a multi-parameter sonde. The zooplankton, phytoplankton, and water-quality data describe a swarm of the in
Datasets of ecological communities (invertebrates and fish), streamflow, habitat, and water quality to examine the presence of trends in ecological communities from the Fountain Creek basin, Colorado, USA, 2003-2016.
These data were used for an analysis as part of a long-term project monitoring the biological communities, habitat, and water quality of the Fountain Creek Basin. Biology, habitat, and water quality data have been collected at 10 sites starting in 2003. These data include annual samples of aquatic invertebrate communities, fish communities, water quality, and quantitative riverine habitat collecte
Geospatial output data from the RVR Meander model of the Wabash River near the Interstate 64 Bridge near Grayville, Illinois
Natural river channels continually evolve and change shape over time. As a result, channel evolution or migration can cause problems for bridge structures that are fixed in the flood plain. A once-stable bridge structure that was uninfluenced by a rivers shape could be encroached upon by a migrating river channel. The potential effect of the actively meandering Wabash River on the Interstate 64 (I

Supplementary data for journal article "Detecting sulfamethoxazole and carbamazepine in groundwater: Is ELISA a reliable screening tool?" published in the Journal of Environmental Pollution
The U.S. Geological Survey, in cooperation with the Minnesota Pollution Control Agency, conducted a study to determine the occurrence of micropollutants in: (1) shallow groundwater near large subsurface treatment systems and rapid infiltration basins and (2) shallow groundwater and soil from an agricultural field that land applies domestic wastewater. Water samples were analyzed with enzyme linked
Magnetotelluric sounding data, stations 26 to 36, north of Wells, Nevada, 2005
This dataset includes the magnetotelluric (MT) sounding data collected in 2005 along an east-west profile north of Wells, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also
West Green River elk herd locations in southwestern Wyoming, 2005-2010
Between 2005 and 2010, 61 adult female elk were trapped using a baited corral trap on Fossil Butte National Monument during winter. An additional 12 female elk were darted from a helicopter during the winter of 2007 near Cokeville, WY, located approximately 20 km northwest of the Monument. We affixed all elk with GPS collars programmed to collect location data every 5 hours. In total we collected
Dataset: Mortality trends in the Washington population of northern sea otters (Enhydra lutris kenyoni) during 20022015
These data document cause of death determination for stranded otters salvaged from the coast of Washington state and northern Oregon for post-mortem analysis.
High resolution helicopter-borne magnetic and electromagnetic survey Eureka Graben area, Colorado September 1999
On September 25, 1998, SIAL Gosciences Inc. (SIAL) was awarded Department of Interior, contract 98CRCN1018, by the U.S. Geological Survey. This contract required SIAL to carry out a high-sensitivity magnetic and electromagnetic helicopter survey over one block located in the Eureka Graben Area near Silverton, Colorado. The primary goal of this project was to provide digitally recorded and processe
