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.

Sediment Thickness Data in the Deep-Sea Basins of the Bering Sea

A raster grid of sediment thickness in GeoTIFF format (BeringSeaBasins-SedimentThicknessGrid.tif) of the Aleutian, Bowers, and Komandorsky Basins was created by merging GeoTIFF grids of the Aleutian and Bowers Basins and of the Komandorsky Basin, provided in other sections of this data release. The raster grid file, along with a corresponding CSDGM FGDC-compliant metadata file, is provided in a zi

Vegetation Transects to Measure Effects of Snow Goose Grazing on the Colville River Delta, Alaska

This data release corresponds to visual vegetation measurements in snow goose grazing areas of the Colville River Delta. Visual vegetation measurements data include functional group percent cover and evidence of goose activity including grazed stems, snow goose grubbing holes, and shoot pulling. These data were collected at a set of four 100m transects located in areas of representative vegetation

Example Groundwater-Level Datasets and Benchmarking Results for the Automated Regional Correlation Analysis for Hydrologic Record Imputation (ARCHI) Software Package

This data release provides two example groundwater-level datasets used to benchmark the Automated Regional Correlation Analysis for Hydrologic Record Imputation (ARCHI) software package (Levy and others, 2024). The first dataset contains groundwater-level records and site metadata for wells located on Long Island, New York (NY) and some surrounding mainland sites in New York and Connecticut. The s

Relative seismic velocity variations correlate with deformation at Kilauea volcano, Hawaii

The dataset includes tiltmeter data at a sample rate of 1 sample per minute from a downhole tiltmeter at Uwekahuna Vault (UWE). Location is -155.291162, 19.420972 (NAD83), elevation 1257 m. Data has two orientations for each time sample (north and east). Each file contains a year of data. The original datasource removes the mean, so the ends of subsequent files will not align. The absolute value o

Alaska Tephra Data

This USGS Data Release presents major-oxide glass geochemical results from tephras erupted form Alaska volcanoes. This data set is in support of volcano hazard studies by the Alaska Volcano Observatory (AVO) where tephra (volcanic ash) deposits are used to assess eruption frequency, magnitude, and character of eruption. These data are part of a larger effort to identify and characterize tephra dep

Acoustic Doppler Current Profiler data collected in near Hammond Bay, Lake Huron, 2019

This dataset records results from a bottom-deployed upward-looking Acoustic Doppler Current Profiler (ADCP, 600 kHz Workhorse Monitor, Teledyne RD Instruments, Poway, California) deployed during the summer of 2019 (late June until early August) near Hammond Bay, Lake Huron (45.5948 degrees north, -84.1542 degrees east). Data were collected in support of nearby Cladophora and benthic algal assessme

Chemical and isotopic data from wetland pond water samples collected in the Cottonwood Lake Study Area, Stutsman County, North Dakota, USA, 2015–2019

This U.S. Geological Survey data release contains chemical, isotopic, and physical data from wetland pond water samples collected at the Cottonwood Lake Study Area, Stutsman County, North Dakota, USA. Samples were collected monthly during the growing season (April or May through September) in 2015, 2016, 2017, and 2019 and in August 2018. Temperature, specific conductance, and pH were measured in

GIS Data for Geologic Map of the White Rock Canyon quadrangle, Carbon County, Wyoming

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the White Rock Canyon quadrangle, Carbon County, Wyoming (Hyden and others, 1968). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in USGS Geologic Quadrangle Map GQ-789. The

Model simulations of the January 15, 2022 Hunga Volcano eruption plume and deposit

This data release accompanies the publication below, and contains the data used in that publication.   Mastin, L.G., Van Eaton, Alexa R., and Cronin, Shane, in press, Did steam boost the height and growth rate of the giant Hunga eruption plume? Bulletin of Volcanology.  https://doi.org/10.1007/s00445-024-01749-1   Within this data release are two zip files: --Supplementary_tables.zip contains th

Predictions of PFAS in groundwater used as a source of drinking water and related data in the conterminous United States

An extreme gradient boosting ensemble tree model predicting per- and polyfluoroalkyl substances (PFAS) occurrence in groundwater at the depths typical of the bottom of public and domestic drinking water supplies across the conterminous United States was developed. PFAS data used to train the model were collected between 2019 and 2022 by the U.S. Geological Survey National Water Quality Network, Gr

Produced water major ion geochemistry, water isotopes, radium content, and field parameters and gas compositions from Niobrara Formation petroleum wells in the Denver-Julesburg Basin

This data release includes field parameters (pH and specific conductance), major ion geochemistry (B, Ba, Br, Cl, Ca, Fe, K, Li, Mg, Mn, Na, Si, SO4, Sr), total dissolved solids, specific gravity, water isotopes (delta-2H and delta-18O), and radium isotopes (226Ra and 228Ra) from produced water samples taken from petroleum wells producing from the Niobrara Formation in the Denver-Julesburg Basin,

Piacenzian (Pliocene) foraminiferal faunal census data from Sites DSDP 594, ODP 642, ODP 846, ODP 882, ODP 982, ODP 1073, ODP 1088, and ODP 1146

Planktic foraminiferal species distributions in the modern ocean track environmental features like latitudinal temperature gradients. Species shift their distributions as the marine environment changes, providing an analog for past behavior. Stationarity of species’ ecological tolerances is a first-order assumption of all paleoenvironmental reconstructions based upon modern analog methods. We are
