Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed...

This data release documents spatiotemporal water-quality, landscape, and climatic conditions in Fairfax County, Virginia from 2007 through 2018. These data were used to evaluate the water-quality and ecological condition of 20 Fairfax County watersheds monitored since 2007. Data include measures of water-quality, precipitation, air temperature, land use, land cover, wastewater and...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of northwestern Minnesota near the town of Mentor. The airborne survey was funded by the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 40...

The datasets in this data release contain the results of an analysis of the U.S. Geological Survey's historical water-use data from 1985 to 2015. Data were assessed to determine the top category of water-use by volume. Data from groundwater, surface water, and total water (groundwater plus surface water) use were parsed by water type, and the top category of use by county or the...

Detailed geologic mapping and sample collection was conducted in rare bedrock exposures of the Denali fault zone during the summer months of 2013, 2014, and 2015 by the U.S. Geological Survey. Data include measurements of structural geologic orientations and documentation of fault zone and host rock characteristics. Representative samples were selected for measurements of fault vein...

Harmful algal blooms (HABs) are overgrowths of algae or cyanobacteria in water and can be harmful to humans and animals directly via toxin exposure or indirectly via changes in water quality and related impacts to ecosystems services, drinking water characteristics, and recreation. While HABs occur frequently throughout the United States, the driving conditions behind them are not well...

A three-dimensional groundwater flow model using MODFLOW 6 (version 6.2.2) was developed and calibrated for unconsolidated Coastal Plain aquifers underlying the Joint Base McGuire-Dix-Lakehurst (JBMDL) and vicinity, New Jersey, to evaluate groundwater flow pathways of per- and polyfluoroalkyl substances (PFAS) contamination associated with use of aqueous film forming foam (AFFF). The...

Here we provide data used to report on changes in tidal marsh elevation in relation to our network of 387 fixed benchmarks in tidal marshes on four continents measured for an average of 10 years. During this period RSLR at these marshes reached on average 6.6 mm yr-1, compared to 0.34 mm yr-1 over the past millennia. While the rate of sediment accretion corresponded to RSLR, the loss of...

This data release compiles element composition data for more than 600 deep-ocean mineral samples from more than 25 research cruises in the Pacific Ocean since 1979 that involved USGS researchers. Deep-ocean mineral sample types encompassed in this data release include ferromanganese crusts, manganese nodules, phosphorites, and hydrothermal minerals. This data release is comprised of both

Agricultural land cover for the western United States. This dataset was developed from Sagestitch, the Eastern Washington Shrubsteppe Mapping Project, and several state level GAP products (AZ, CA, NM, OR, and WA).

KiteNest is a spatially explicit model of Everglades snail kite (Rostrhamus sociabilis plumbeus) relative nest site selection that quantifies the relationships between a range of environmental factors and nest site selection specific to the southern portion of the species' range. Using hydrologic conditions such as mean 2-week water depth and water depth change rate, days since the last...

This dataset includes processed satellite tracking data collected from green turtles between July 2002 and October 2020 in the Gulf of Mexico along the west coast of Florida from the Florida Keys to the Gulf Islands National Seashore. It contains model output including from the state-space model (SSM) described in Lamont et al. (2022) and centroids associated with the 50 percent and 95...
