Per- and polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2022 Per- and polyfluoroalkyl Substances in Drinking Water at Select Public Water Systems in West Virginia, 2022
These data were collected to understand the occurrence of per- and polyfluoroalkyl substances in drinking water samples at public water systems identified to have perfluorooctanoic acid or perfluorooctane sulfonic acid above laboratory reporting levels in previously collected raw-water samples, and provide a review of the analytical results. The West Virginia Department of Health and...
Geochronological Data for the Deep Creek paleoseismic site, Wasatch fault zone, Utah Geochronological Data for the Deep Creek paleoseismic site, Wasatch fault zone, Utah
This data release includes geochronological data for a natural exposure of the Wasatch fault, Utah at the Deep Creek site (39.507462?, -111.861790?). Laboratory data include 11 optically stimulated luminescence (OSL) ages for quartz, 23 charcoal radiocarbon ages, and 342 portable OSL (bulk luminescence) measurements. The radiocarbon and luminescence samples were collected November 2019...
Data Release for Luminescence: Construction and modification of debris-flow alluvial fans as captured in the geomorphic and sedimentary record: examples from the western Sangre de Cristo Mountains, south-central Colorado Data Release for Luminescence: Construction and modification of debris-flow alluvial fans as captured in the geomorphic and sedimentary record: examples from the western Sangre de Cristo Mountains, south-central Colorado
The following report summarizes the dating results from the San Luis Valley-Pioneer Fan 2017-2019 dating project. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be...
Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2023 Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2023
These datasets provide early estimates of 2023 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from May to early July. The EAG estimates are developed typically within 7-13 days of the latest satellite observation used for that version. Each weekly release contains four fractional cover maps along with their corresponding...
Percent vegetation cover, bare ground and presence of erosional features on managed Conservation Reserve Program fields across central and western United States, 2016-2019 Percent vegetation cover, bare ground and presence of erosional features on managed Conservation Reserve Program fields across central and western United States, 2016-2019
Data included in this data set are from edge-of-field surveys of managed fields that recorded the presence of erosional features and cover of vegetation and bare ground on 320 Conservation Reserve Program (CRP) fields across central and western United States. Field sampling data was recorded across six US Department of Agriculture Farm Production Regions (Corn belt, Lake states, Mountain...
Magnitude and Frequency of Floods for Rural Streams in Georgia, South Carolina, and North Carolina, 2017-Data Magnitude and Frequency of Floods for Rural Streams in Georgia, South Carolina, and North Carolina, 2017-Data
Reliable estimates of the magnitude and frequency of floods are an important part of the framework for hydraulic-structure design and flood-plain management. Annual peak flows measured at U.S. Geological Survey streamgages are used to compute flood-frequency estimates at those streamgages. However, flood-frequency estimates also are needed at ungaged stream locations. A process known as
Model Archive for Magnitude and Frequency of Floods for Rural Streams in Georgia, South Carolina, and North Carolina, 2017 Model Archive for Magnitude and Frequency of Floods for Rural Streams in Georgia, South Carolina, and North Carolina, 2017
Reliable estimates of the magnitude and frequency of floods are an important part of the framework for hydraulic-structure design and flood-plain management in Georgia, South Carolina, and North Carolina (study area). Annual peak flows measured at U.S. Geological Survey streamgages were used to compute at-site flood-frequency estimates at those streamgages in the study area based on...
Model input and output from Precipitation Runoff Modeling System (PRMS) simulation of the Red River basin 1981-2016 Model input and output from Precipitation Runoff Modeling System (PRMS) simulation of the Red River basin 1981-2016
This data release contains input and output data from hydrologic simulations of streamflow conditions in the Red River Basin (RRB) using the Precipitation-Runoff Modeling System (PRMS). The RRB PRMS model predicts components of the water balance at 3065 hydrologic response units (HRU) and streamflow for 1614 stream segments within the model domain for the simulation period 1981 to 2016...
Voltages measured on long grounded electrically conducting lines in North American during several magnetic storms, 1891-1940 Voltages measured on long grounded electrically conducting lines in North American during several magnetic storms, 1891-1940
Presented is a list of voltages (electric potential differences) measured during magnetic storms on grounded long lines in the United States and Canada between 1891 and 1940. The sources for the list are published papers, technical documents, and newspapers. Each entry consists of the maximum voltage measured for each storm on a specified line connecting two ground points, nominally...
Sediment Data From Vibracores and Sand Augers Collected in 2021 and 2022 From Fire Island, New York Sediment Data From Vibracores and Sand Augers Collected in 2021 and 2022 From Fire Island, New York
In 2021 and 2022, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) and the USGS New York Water Science Center (NYWSC), on behalf of SPCMSC, conducted sediment sampling and ground penetrating radar (GPR) surveys at Point O' Woods and Ho-Hum Beach (NYWSC, 2021) and Watch Hill, Long Cove, and Smith Point (SPCMSC, 2022), Fire Island...
Meteorological data from edge-of-field sites in Michigan and Wisconsin, 2015-18 Meteorological data from edge-of-field sites in Michigan and Wisconsin, 2015-18
These data describe daily mean air temperature, soil temperature, soil-water (moisture) content, and solar radiation at two edge-of-field sites monitored as part of the Great Lakes Restoration Initiative. These data were used to catalog the general range of conditions at each site in order to provide context for when sub-surface agricultural drainage (tile drains) is visible in remote...
