Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Lake Koocanusa Water Quality Profiles for 2019 through 2024 Lake Koocanusa Water Quality Profiles for 2019 through 2024
This data release contains water quality data from discrete sonde profiles taken at 10 sites on Lake Koocanusa from 2019 through 2024. The profiles include measurements of water temperature, specific conductance, dissolved oxygen, pH, turbidity, and chlorophyll relative fluorescence as well as the depth of the sonde below the water surface. These data were collected as part of a water...
Growth and survival of a Unionid Mussel (Fatmucket, Lampsilis siliquoidea) during Chronic Exposures Evaluating pH Effects on Ammonia Growth and survival of a Unionid Mussel (Fatmucket, Lampsilis siliquoidea) during Chronic Exposures Evaluating pH Effects on Ammonia
This data set contains toxicity data from short term 7-day chronic water-only bioassays to assess the effects pH on ammonia toxicity to survival and growth of a juvenile fatmucket mussel (Lampsilis siliquoidea). We conducted 4 concurrent exposures at nominal pHs of 7.0, 7.5, 8.0, and 8.5 with varying ranges of ammonia to capture effect concentrations. This data set has three tables: (1)...
Cattle Habitat Selection Index for the Great Basin region in the western United States Cattle Habitat Selection Index for the Great Basin region in the western United States
We collected cattle GPS location data within three sites across the Great Basin ecoregion. We then coupled these data with multi-resolution remotely sensed vegetation, hydrology, and topographic data to develop a cattle resource selection surface across Nevada and northeastern California. This layer can support grazing management through targeted or rotational grazing by providing a...
Photographs and photomicrographs of selected pre-Middle Jurassic basement rocks beneath the Atlantic and Gulf Coastal Plains in Florida Photographs and photomicrographs of selected pre-Middle Jurassic basement rocks beneath the Atlantic and Gulf Coastal Plains in Florida
This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization...
Mineral abundances of selected pre-Middle Jurassic basement rocks beneath the Atlantic and Gulf Coastal Plains in Florida and Alabama from whole-rock powder X-ray diffraction analysis and the Rietveld method Mineral abundances of selected pre-Middle Jurassic basement rocks beneath the Atlantic and Gulf Coastal Plains in Florida and Alabama from whole-rock powder X-ray diffraction analysis and the Rietveld method
This data release reports the mineral abundances in samples of pre-Middle Jurassic basement rocks from twenty-nine (29) boreholes in Florida and southern Alabama. Mineral abundances are quantified from whole-rock powder X-ray diffraction (XRD) data and the Rietveld method and are reported in weight percent or, where present near the detection limit (~1 wt.% depending on mineral), as...
Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across Western North America from 1985-2024 Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across Western North America from 1985-2024
The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2024. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub...
