Data

Concentration and quality assurance results for organic compounds and bioassay endocrine activity results analyzed at the U.S. Geological Survey National Water Quality Laboratory, Denver, Colorado, Organic Chemistry Research Laboratory, Sacramento, California, the Organic Geochemistry Research Laboratory, Lawrence, Kansas, and the U.S. Environmental Protection Agency, Office of Research...

This data release contains concentration and quality-assurance results for inorganic, organic analytes and microbiological pathogens collected from 30 different commercial bottled water sources. Samples were processed on July 20 and August 17, 2020 at the New Jersey Water Science Center and analyzed at various U.S. Geological Survey laboratories. Samples were analyzed for nutrients...

Wild lesser scaup from the Chesapeake Bay, captured and implanted with satellite transmitters for a separate ecology study, were opportunistically sampled for avian influenza. These data detail the virological sampling results, obtained post release, which include a single positive for clade 2.3.4.4 H5N1 virus of the A/goose/Guangdong/1/1996 (Gs/GD) H5N1 lineage of highly pathogenic IAV...

These data provide temperatures and relative conductivity to determine the presence or absence of water at specific locations in Dixie Meadows, Dixie Valley, Churchill County, Nevada, 2019-2021.

In coastal wetlands, one of the most striking examples of climate change is the poleward range expansion of mangrove forests in response to warming winters. In North America, the Cedar Key region has often been considered the range limit for mangroves along the western coast of Florida (USA). However, within the past several decades, robust stands of Avicennia germinans and Rhizophora...

This dataset contains data pertaining to chaparral vegetation dieback based on the difference or change in the Normalized Difference Vegetation Index (NDVI) prior to and 6 years into an extensive drought before the 2017 Thomas and 2018 Woolsey Fires in southern California. The difference in mean NDVI is provided for 9322 study plots as are values for a number of physical and...

The U.S. Geological Survey (USGS) has developed and implemented an algorithm that identifies burned areas in temporally-dense time series of Landsat Analysis Ready Data (ARD) scenes to produce the Landsat Burned Area Products. The algorithm makes use of predictors derived from individual ARD Landsat scenes, lagged reference conditions, and change metrics between the scene and reference...

We developed the North American Freshwater Migratory Fish Database (NAFMFD) that synthesizes current knowledge of migratory status, pattern, and behavior for native and non-native freshwater fish species throughout North America, including 1,241 species representing 79 families and 322 genera.

Locations of focused (or ‘preferential’) groundwater discharge to surface water are often hydrologically and ecologically important, yet our ability to predict the spatial distribution and water quality of preferential riverbank discharges is limited at the scale of river networks. To advance the understanding of the physical controls on riverbank groundwater discharge processes...

This data release consists of tables with the thickness and particle-size characteristics of overbank sediment deposited in May 1978 along the valley of Powder River in southeastern Montana. About 900 sediment samples were collected at regularly-spaced distances from 20 valley transects along a 90-kilometer reach of Powder River between Moorhead and Broadus, Montana. The decrease in...

The Chicot aquifer system is a vital water resource for Southwestern Louisiana, providing nearly half of the fresh groundwater the region consumes (Sargent, 2011). The aquifer’s surficial confining unit consists of a wedge-shaped thickening sequence of south to southeastern dipping, interbedded clays and coarser material (primarily sand and gravel). In collaboration with the Louisiana...

This dataset includes photographic images of thin sections created from hand samples and drill core sourced from the South Kawishiwi Intrusion, Duluth Complex, Minnesota, along with two shapefiles representing the locations of the samples and drill hole collars. The samples were collected and core was drilled in order to define copper-nickel-platinum-group element resources associated...
