Karst hydrologic systems are important resources in the state of Tennessee both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater systems in karst systems. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of Conservation (

Understanding how climate change will contribute to ongoing declines in sagebrush ecological integrity is critical for informing natural resource management. We assessed potential future changes in sagebrush ecological integrity under a range of scenarios using an individual plant-based simulation model, integrated with remotely sensed estimates of current sagebrush ecological integrity. The simul

Soil, soil porewater, groundwater, and playa lake sediment samples were collected between September 2021 and November 2023 at Cannon Air Force Base (CAFB) in eastern New Mexico as part of a study on the sources, fate, and transport of per- and polyfluoroalkyl substances (PFAS). Soil cores (2-foot-long) were collected in September 2021 from six sites that were potential PFAS source areas and one ba

Culebra Range of the Sangre de Cristo Mountains, Colorado. Sample Collection: Ponderosa pine (Pinus ponderosa), Douglas-fir (Pseudotsuga menziesii), Bristlecone pine (Pinus aristate), and Limber pine (Pinus flexilis) living in lower and upper montane slopes of the Culebra Range (~Latitude 37˚N, ~Longitude -105˚W WGS84). The Fire-Climate-Human NGGDPP archive collection was obtained in two separate

Global climate models (GCMs) are computationally intensive, physics-based research tools used to simulate the climate system. GCM can also be useful in applied research contexts with the use of statistical downscaling techniques. This collection of statistically downscaled climate projections includes 7 sets of SD-processed CMIP5 projections and 12 sets of SD-processed CMIP6 projections of daily h

Conservation planners and resource managers are concerned about ecological resilience and survival of species as climate and sea level change. The fossil record contains an excellent means to test species responses to changing conditions. This dataset utilizes molluscan faunal data extracted from a fossil database – the Paleobiology Database (PBDB; https://paleobiodb.org/classic) – for the late Pl

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Galax 30 x 60 minute quadrangle in Virginia and North Carolina. The source data used to construct this imagery consists of 1-meter, 1/9 arc-second (3-meter) and 3-feet lidar-derived digital elevation models (DEMs). Lidar point cloud data (LPCs) were used to construct DEMs at a 3-meter resolution in parts of North Car

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Wytheville 30 x 60 minute quadrangle in Virginia and North Carolina. The source data used to construct this imagery consists of 1 and 3-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2012 and 2021. The data were processed using ge

This data release contains the results from hydrograph separation analysis for 44 separate sites within the Columbia Plateau region of the Pacific Northwest. The hydrograph separation program (HYSEP) (Sloto and Crouse, 1996) was used to perform baseflow separation. HYSEP is an automated approach to traditional graphical hydrograph separation methods and was utilized for this study. For the steady-

The released data contain both a csv and parquet file summarizing the Centers for Disease Control (CDC) Social Vulnerability Index (SVI), at the NHDPlus V2 stream catchment scale. Dasymetric mapping was utilized to bound 2014 populations to the 2013 National Land Cover Dataset and then trim them to NHDPlus V2 catchments. These produced data are summarized as numbers of people within each listed ca

The California State Water Resources Control Board (State Water Board) initiated the Oil and Gas Regional Monitoring Program (RMP) to assess effects of oil and gas development on groundwater designated for any beneficial use. The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in cooperation with the

To better understand pesticide exposure, silicone band samples were placed in five National Wildlife Refuges in the Sacramento Valley of Northern California. Silicone bands, used as aerial passive sampling collection devices, were flag-pinned half a meter off the ground and deployed for 28 days in the spring of 2023 (total of 176 bands). Upon retrieval, silicone bands were extracted via sonication
