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.

Semiquantitative mineralogy results from powder X-ray diffraction (XRD) analyses of mineral scales from The Geysers geothermal field, California, USA Semiquantitative mineralogy results from powder X-ray diffraction (XRD) analyses of mineral scales from The Geysers geothermal field, California, USA
This data release provides semiquantitative mineralogy results from X-ray diffraction (XRD) analyses of mineral scales from The Geysers vapor-dominated geothermal field in California. The mineral species and their abundances are reported in weight percent and values have been normalized to total 100 percent for each sample. The X-ray diffraction results show that the mineral samples from...
The major, minor, and trace element geochemistry of mineral scales from The Geysers geothermal field, California, USA The major, minor, and trace element geochemistry of mineral scales from The Geysers geothermal field, California, USA
This data release provides quantitative whole rock geochemical results from The Geysers vapor-dominated geothermal field in California. The concentrations of major elements are reported in oxide weight percent by wavelength dispersive x-ray fluorescence (WDXRF), the concentrations for sixty elements are reported in elemental weight percent (pct) or parts per million (ppm) from...

This dataset contains supporting files for particle tracking simulations of the Upper Missouri River near Wolf Point, MT.
Turbidity Data from the Upper Esopus Creek Watershed, New York Turbidity Data from the Upper Esopus Creek Watershed, New York
This data release contains continuous (15-minute interval) turbidity data from the upper Esopus Creek Watershed in the Catskill Mountain Region of New York State. The upper Esopus watershed drains to the Ashokan Reservoir, part of the New York City (NYC) drinking water supply system. Turbidity is a primary water-quality concern in the NYC water-supply system, particularly in the upper...
2011 and 2017 Pika Pathology Colorado 2011 and 2017 Pika Pathology Colorado
American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling...
Development of High Surface Area Organosilicate Nanoparticulate Thin Films for Use in Sampling Hydrophobic Compounds in Sediment-Data Development of High Surface Area Organosilicate Nanoparticulate Thin Films for Use in Sampling Hydrophobic Compounds in Sediment-Data
The data set describes the characterization of organosilica nanoparticle thin films used to adsorb PCBs from laboratory water and a sediment collected near Anniston Alabama. Data not shown here for the porewater and sediment PCB concentrations can be found in Appendix 1 of Ingersoll et al. 2014 (http://dx.doi.org/10.3133/sir20135125) Bulk sediment chemistry was obtained from Table A1-3a...
Snow drought classification and streamflow timing and magnitude signatures for snow dominated USGS watersheds in the Conterminous United States from 1980 to 2020 Snow drought classification and streamflow timing and magnitude signatures for snow dominated USGS watersheds in the Conterminous United States from 1980 to 2020
This data release contains snow drought classifications as well as streamflow timing and magnitude signatures for gaged, snow-dominated U.S. Geological Survey (USGS) watersheds in the Conterminous United States (CONUS) from 1980 to 2020 supporting the journal article "Snow drought classification and streamflow timing and magnitude signatures for snow dominated USGS watersheds in the...
Microbial source tracking for streams in Scott County, Iowa, 2023 Microbial source tracking for streams in Scott County, Iowa, 2023
Surface water samples (n = 33) were collected in fall of 2023 at stream sites in Scott County Iowa, USA and were analyzed for microbial source tracking markers by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Microbial source tracking markers identify fecal sources of contamination by detecting microbes that are specific to...
Simulations of larval fish transport and environmental conditions in Lake Michigan Simulations of larval fish transport and environmental conditions in Lake Michigan
Data files contain the simulated mean daily environmental conditions experienced by particles (which can be assumed to be planktonic larval alewife or yellow perch) in Lake Michigan during March 15 - July 31 of past and future years. Simulations were generated by integrating a series of climatic, hydrodynamic, biogeochemical, and Lagrangian particle dispersion (LPD) models. For each year...
Ungulate Migrations of the Western United States, Volume 4 Ungulate Migrations of the Western United States, Volume 4
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 4 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and...
Laboratory analyses for fish tissue samples from Lake Koocanusa and Kootenai River Basin, Montana, 2022 (ver. 2.0, May 2025) Laboratory analyses for fish tissue samples from Lake Koocanusa and Kootenai River Basin, Montana, 2022 (ver. 2.0, May 2025)
This data release includes laboratory analyses for fish tissue samples collected from Lake Koocanusa and the Kootenai River Basin in Montana during 2022. Samples were collected by the U.S. Geological Survey (USGS) Wyoming-Montana Water Science Center (WY-MT WSC) in cooperation with Montana Fish, Wildlife and Parks (MT FWP) and Montana Department of Environmental Quality (MT DEQ)...
