This dataset consists of five tables, 1) shorebird morphological measurements collected from various species captured from 1895-2021, 2) taxonomy, 3) contributors, 4) sampling locations, and 5) cross-reference publications. In addition, photographs of plumage patterns are available for several species. Researchers with the U.S. Geological Survey - Alaska Science Center, along with...
Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2023 Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2023
The California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) analyzed for per-and polyfluoroalkyl substances (PFAS) in groundwater samples collected from domestic and public drinking water supply wells in California. GAMA-PBP is a cooperative program between the U.S. Geological Survey and the California State Water Resources Control Board. This...
Simulated Recharge Areas to Surface Waters and Public-Supply Wells with Travel Times Greater Than and Less Than 10 Years For Average 2005-2015 Conditions, Long Island, NY Simulated Recharge Areas to Surface Waters and Public-Supply Wells with Travel Times Greater Than and Less Than 10 Years For Average 2005-2015 Conditions, Long Island, NY
This data release contains model simulation results of a particle tracking analysis to delineate areas that provide recharge to surface waters and public-supply wells on Long Island, NY. The analysis partitions the recharge areas based on particle travel times of greater than or less than 10 years to reach the receiving surface water or well. The simulation was performed using a regional...
Hydraulic Conductivity and Transmissivity Estimates from Slug Tests in Wells Within the Mississippi Alluvial Plain, Arkansas and Mississippi, 2020 Hydraulic Conductivity and Transmissivity Estimates from Slug Tests in Wells Within the Mississippi Alluvial Plain, Arkansas and Mississippi, 2020
During the spring and summer of 2020, the U.S. Geological Survey, Lower Mississippi – Gulf Water Science Center, conducted single well slug tests on selected wells within the Mississippi Alluvial Plain in Arkansas and Mississippi to estimate hydraulic conductivity (K) and transmissivity (T) values for the aquifers in which the wells are screened. A total of 324 tests were conducted on 48...
State-and-Transition Simulation Models to explore post-fire habitat restoration in three greater sage-grouse (Centrocercus urophasianus) Priority Areas for Conservation, USA (2018-2068) State-and-Transition Simulation Models to explore post-fire habitat restoration in three greater sage-grouse (Centrocercus urophasianus) Priority Areas for Conservation, USA (2018-2068)
Wildfires are increasingly modifying wildlife habitat in the western United States and managers need ways to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. We simulated post-fire revegetation and greater sage-grouse (Centrocercus urophasianus) habitat restoration using a spatially explicit state-transition simulation model...
Groundwater-quality data in the Kern County Domestic-Supply Aquifer Study Unit, 2022: Results from the California GAMA Priority Basin Project Groundwater-quality data in the Kern County Domestic-Supply Aquifer Study Unit, 2022: Results from the California GAMA Priority Basin Project
The U.S. Geological Survey collected groundwater samples from 33 wells used for domestic and small system drinking water supplies in Kern County, California in 2022. The wells were sampled for the Kern County Domestic-Supply Aquifer Study Unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the...
Estimated crop irrigation water use withdrawals in San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin, Arizona for 2022 Estimated crop irrigation water use withdrawals in San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin, Arizona for 2022
Observations of irrigated agricultural land within the San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin. Digitized field boundaries were used to locate crops for in situ verification twice in 2022; crop verification occurred first on May 18th and again on August 24th. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery...
Estimated crop irrigation water use withdrawals in Hualapai Valley Groundwater Basin, Arizona for 2022 Estimated crop irrigation water use withdrawals in Hualapai Valley Groundwater Basin, Arizona for 2022
Observations of irrigated agricultural land within the Hualapai Valley Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification once in 2022; crop verification occurred on June 2nd. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2021 imagery for Arizona and...
NGWOS Ground-Based Discrete Snowpack Measurements Data Release (ver. 2.0, March 2026) NGWOS Ground-Based Discrete Snowpack Measurements Data Release (ver. 2.0, March 2026)
Ground-based discrete snowpack measurements were collected during winter field campaigns starting in 2020. These data were collected as part of the U.S. Geological Survey (USGS) Next Generation Water Observing System (NGWOS) Upper Colorado River Basin project focusing on the relation between snow dynamics and water resources. This data release consists of three child items. Each child...
