This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional and continuous oil and gas resources in the Los Angeles Basin Province, California. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within...

The U.S. Geological Survey collected groundwater samples from 44 wells used for domestic and small system drinking water supplies in the western Central Valley, California in 2023. The wells were sampled for the Western Central Valley domestic-supply aquifer study unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin...

This dataset includes fish population and habitat data collected in 2024 to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcuttii) in the Santa Ana River, California.

This GIS shapefile, "density_contours," describes 1) a bison study area at Tallgrass Prairie National Preserve, Kansas, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2021-2023. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the

This GIS shapefile, "density_contours," describes 1) a bison study area at Wind Cave National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2019-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the...

This GIS shapefile, "density_contours," describes 1) a bison study area in the North Unit of Theodore Roosevelt National Park, North Dakota and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2017-2020. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass...

This dataset includes information collected before and after a 2023 copper treatment was implemented by the State of Idaho to eradicate invasive quagga mussels in the Snake River, Idaho. Water, sediment, periphyton, and macroinvertebrates were sampled at Snake River sites upstream, within, and downstream of the copper treatment reach in order to evaluate the fate and transport of the...

The GIS shapefile "bison_locations" provides 132996 locations of 5 adult female bison marked with global positioning system (GPS) collars at Tallgrass Prairie National Preserve during February 2021 to November 2023. We provide locations computed at 15-min and 1-h intervals for individual bison and the date and time of acquisition for each location. Users are advised that ground...

This GIS shapefile, "density_contours," describes 1) a bison study area at Badlands National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2015-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the...

This data release includes laboratory analyses for biofilm and bed-sediment samples collected from streams in the Clark Fork Basin, spanning from Butte to near Missoula, Montana. Samples were collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency as part of a long-term monitoring program. Biofilm samples were collected once at 19 sites...

The dataset includes .csv spreadsheets which provide whole rock geochemical data for the alkaline silicate rock and carbonatite rock samples for the Mountain Pass Intrusive Suite that were analyzed as part of this study, as well as whole rock Rb-Sr and Sm-Nd isotopic data for whole rock alkaline silicate samples. The .csv files containing this data are associated with individual data...

In unconsolidated glacial sediments and exhumed bedrock of Minnesota, USA, landslides may occur on low-relief steep slopes generated by post-glacial fluvial network development and drainage of glacial lakes. As part of an investigation to understand the link between various environmental variables, post-glacial landscape development, and a previously mapped landslide inventory, we...
