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.

Multichannel minisparker, multichannel boomer, and chirp seismic-reflection data of USGS field activity 2017-612-FA collected in Puget Sound and Lake Washington in February of 2017
High-resolution multichannel minisparker, multichannel boomer and chirp seismic-reflection data were collected by the U.S. Geological Survey and the University of Washington in February of 2017 west of Seattle in Puget Sound and in Lake Washington, Washington. Data were collected aboard University of Washington's R/V Clifford A. Barnes during USGS field activity 2017-612-FA. Sub-bottom acoustic pe
Chirp sub-bottom data of USGS field activity K0211PS collected in Puget Sound, Washington in April of 2011
High-resolution chirp sub-bottom data were collected by the U.S. Geological Survey in April 2011 south of Bainbridge Island and west of Seattle in Puget Sound, Washington. Data were collected aboard the R/V Karluk during field activity K0211PS using an Edgetech SB-512i sub-bottom profiler. Sub-bottom acoustic penetration spans several tens of meters and is variable by location.
Bathymetry of the Similkameen River Above Enloe Dam Near Oroville, Washington
This data release provides the results of the bathymetric survey of the Similkameen River directly above Enloe Dam which took place over three days in late September 2020. The bathymetric survey was completed to enable an instrument-based estimate of the volume of legacy sediment impounded behind Enloe Dam. A shoreline water level survey collected points at the river?s edge using Trimble R8 GNSS
INHABIT species potential distribution across the contiguous United States
We developed habitat suitability models for invasive plant species selected by Department of Interior land management agencies. We applied the modeling workflow developed in Young et al. 2020 to species not included in the original case studies. Our methodology balanced trade-offs between developing highly customized models for a few species versus fitting non-specific and generic models for numer
Low-streamflow and precipitation trends for 183 U.S. Geological Survey streamgages in the Chesapeake Bay Watershed
This data release contains low-streamflow trend results from 183 U.S. Geological Survey (USGS) streamgages and precipitation trend results from gaged watersheds within the Chesapeake Bay Watershed. Data include streamgage identification number, trend slopes and significance for several low-streamflow and precipitation metrics.
Geochemical and 40Ar/39Ar Analytical Data of Rocks from Glacier Bay National Park and Preserve
This data set contains major and trace element geochemical data and 40Ar/39Ar isotopic data and ages for rock samples collected during 2016 fieldwork in Glacier Bay National Park and Preserve. The plutonic rock samples were collected for radiometric age determinations to test for the presence of the Late Jurassic to Early Cretaceous (130-160 Ma) Saint Elias suite. The age analyses indicate that al
Diets and Stable Isotopes of Fishes in Rodeo Lagoon, California, 2016-2017
This dataset includes lab data for fish, fish diets, and stable isotopes for fish tissue, vegetation, and invertebrates collected during daylight hours in the Rodeo Lagoon and Lake in Golden Gate National Recreation Area at the Pacific Coast, USA during 2016 and 2017. This data release includes all animal taxa, and isotope values included in the analysis.
Eriogonum visheri (Visher's buckwheat) seed, pollen, and insects at Badlands National Park, South Dakota, USA, 2014-2015, 2017
This data record contains fitness data for Visher's buckwheat (Eriogonum visheri) for the years 2014, 2015 and 2017 at Badlands National Park, South Dakota, USA. These data include insect visitation, pollen deposited on stigmas, achene size and germination over three field seasons (two field seasons for germination: 2015 and 2017) in four populations (two populations in 2017).
County-Level Geographic Distributions for 47 Exotic Plant Species in Midwest USA and Central Canada, Compiled 2019
Geographic distribution data were collected based on county level occurrences (or converted from point occurrences to county level occurrences) within the five focal states (Minnesota, North Dakota, South Dakota, Nebraska & Iowa) and each U.S. state or Canadian province bordering those focal states (Wisconsin, Illinois, Missouri, Kansas, Wyoming, & Montana in the USA and Saskatchewan, Ontario & Ma
Historical Length, Weight, and Fecundity of Silver Chub (Macrhybopsis storeriana) in Western Lake Erie
This data set provides a table of length, weight, sex, and estimated fecundity of Silver Chub Macrhybopsis storeriana in western Lake Erie from 1979 through 1987. These data are potentially useful to those studying recovery and restoration of Silver Chub in Lake Erie. These data were collected as part of routine trawl surveys in western Lake Erie. Other data associated with these data can be found
The Basin Characterization Model - A monthly regional water balance software package (BCMv8) data release and model archive for hydrologic California (ver. 4.0, May 2024)
This data release accompanies the USGS Techniques and Methods report titled: "The Basin Characterization Model - A Regional Water Balance Software Package" (Flint et al., 2021, https://doi.org/10.3133/tm6H1), and includes all necessary Basin Characterization Model version 8 (BCMv8) inputs and outputs for water years 1896 to 2023. The BCMv8 was refined from the previous BCMv65 version to improve th
Lake Erie Aquatic Vegetation data
Observations and subtle shifts of vegetation communities in western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation
