Groundwater Drought Metrics for Selected Groundwater Wells in the conterminous U.S. from 1981-2020 and from 2001-2020 Groundwater Drought Metrics for Selected Groundwater Wells in the conterminous U.S. from 1981-2020 and from 2001-2020
This metadata record describes a series of datasets containing metrics used to characterize drought for groundwater wells in the conterminous United States (CONUS). This data is associated with a publication that looks to answer questions about groundwater drought in CONUS. The publication uses the time periods 1981-2020 and 2001-2020, but this dataset includes additional time periods...
Data from Decadal Change in Groundwater Quality Web Site, 1988-2024 Data from Decadal Change in Groundwater Quality Web Site, 1988-2024
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...
Predicted carbon fluxes in Lake Maurepas swamp forests under various hydrologic and salinity regimes Predicted carbon fluxes in Lake Maurepas swamp forests under various hydrologic and salinity regimes
A process-driven biogeochemistry model, Wetland Carbon Assessment Tool - DeNitrification-DeComposition model (WCAT-DNDC) was validated and applied to examine the responses of daily net ecosystem exchange (NEE), net primary productivity (NPP), ecosystem respiration (ER), methane (CH4) and nitrous oxide (N2O) emissions in the Lake Maurepas swamp forests under dry (2011), normal (2019), and...
Cooperative National Geologic Map: Precambrian geology Cooperative National Geologic Map: Precambrian geology
The USGS National Cooperative Geologic Mapping Program (NCGMP) was directed by Congress to create a new geologic map of the United States” by “bring[ing] together detailed national and continental-resolution 2D and 3D information produced throughout the Survey and by federal and state partners” (House Report 116-100). To fulfill this goal, the NCGMP created a map synthesis engine...
