Long-term water-quality trends for rivers and streams within the contiguous United States using Weighted Regressions on Time, Discharge, and Season (WRTDS)

The U.S. Geological Survey (USGS) Water Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand. It is also improving understanding of the natural and human factors affecting the balance between supply and demand. A key part of these

Four Mile Canal Terracing and Sediment Trapping (TV-18): 2015 and 2018 land-water classifications

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting

Maps of multiple future threats and stable areas for Gunnison sage-grouse habitats across three scenarios (2016-2070)

This dataset contains a series of maps of projected threats and current state of habitats for the threatened Gunnison sage-grouse (Centrocercus minimus). The maps are 30-m spatially explicit projections of current habitats (2016) and future landscape change (by 2070) for the full range of the species’ seven extant populations, which cover diverse ecoregions of the imperiled sagebrush biome of the

Pacific Walrus Coastal Haulout Images from Carcass Surveys

This data package contains digital images, survey location logs and a summary tabulation from carcass survey conducted at walrus haulouts in Alaska. A summary of image collection times is provided as a tabular file.

Data release of isotope geochemistry, mineral chemistry, and geochronology for a Proterozoic paragneiss sampled from drill core from North Dakota

This U.S. Geological Survey (USGS) data release provides whole rock isotope geochemistry, zircon hafnium isotope geochemistry, feldspar mineral chemistry, and zircon, monazite, and xenotime geochronology for a paragneiss sampled from a drill core from North Dakota. The sample was collected from the 9-11R E-M Larson well in order to constrain the depositional age, provenance, metamorphic history, a

A geodatabase of Woodruff, K.D., and Christopher, M.J., 1982, Thickness of Regolith in the Delaware Piedmont: Delaware Geological Survey Open File Report No. 19, scale 1:24,000.

This Scientific Data Release is a spatial geodatabase containing Woodruff, K.D. Christopher, M.J., 1982, Thickness of Regolith in the Delaware Piedmont: Delaware Geological Survey Open File Report No. 19, scale 1:24,000, formatted to Geologic Map Schema (GeMS) standards. These geospatial data depict the total thickness (regolith) of both the loose, transported material and the weathered rock that

GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Fortymile Herd, Alaska, 1998-1999

These data were part of a pilot tracking study of three adult female caribou from the Fortymile Herd in Alaska. The dataset is comprised of two comma separated values (.csv) files. Data includes: 1) processed (i.e., erroneous locations removed) GPS locations for caribou, received once per hour for 6 months (October 1998 to April 1999), and 2) spatial, temporal, and biological attributes of three f

Cenozoic Foraminiferal Collections of Weldon Rau in Oregon and Washington, USA

The original compilation of this data is in Rau (2004) (https://www.dnr.wa.gov/Publications/ger_dr4_pacific_nw_foram_collections.zip), where most samples are located by Township, Range, and Section relative to the Public Land Survey System. For this database, Snavely's original field sheets and notebooks were used to calculate latitude and longitude of the samples and the results were combined wit
