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 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...
Vegetation Transects to Measure Effects of Snow Goose Grazing on the Colville River Delta, Alaska 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...
Example Groundwater-Level Datasets and Benchmarking Results for the Automated Regional Correlation Analysis for Hydrologic Record Imputation (ARCHI) Software Package 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...
Relative seismic velocity variations correlate with deformation at Kilauea volcano, Hawaii 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...
Code for long-term monitoring reveals management effects on Prairie Warbler colonization, local extinction, and detection in a Massachusetts Pine Barren Code for long-term monitoring reveals management effects on Prairie Warbler colonization, local extinction, and detection in a Massachusetts Pine Barren
This repository contains all of the scripts to reproduce the analyses, figures, and tables associated with the manuscript Gordon et al. in prep. There is 1 R script that does the following: (1) format the data, (2) explores the data, and (3) goes through the analyses for each objective.
Alaska Tephra Data, 2018 Alaska Tephra Data, 2018
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...
