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.

Magnetotelluric data across the Southern San Andreas Fault Zone, California Magnetotelluric data across the Southern San Andreas Fault Zone, California
The Southern San Andreas fault (SSAF) poses one of the largest seismic risks in California. However, structural properties around Coachella Valley remain enigmatic. In 2019, we collected magnetotelluric soundings (MT) to help inform depth-dependent fault zone geometry, fluid content and porosity. This project was led by the Institute of Geophysics and Planetary Physics at the University...
ModelMuse Version 5.1: Software Release ModelMuse Version 5.1: Software Release
ModelMuse version 5.1 updates version 5.0 by adding support for the groundwater transport process and time series files in MODFLOW 6.
Molecular and morphological data for Channa aurolineata in Florida Molecular and morphological data for Channa aurolineata in Florida
We analyzed morphological and molecular data from one existing and one newly discovered population of 'bullseye' snakehead (Teleostei: Channidae) from Florida. Morphological and meristic data were collected from museum collections and compared with data from recent taxonomic revisions of related species in the 'Marulius' species group from southeast Asia. Additionally, we performed DNA...
Twelve-digit hydrologic unit total flow and snowmelt from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System, 1980-2016 Twelve-digit hydrologic unit total flow and snowmelt from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System, 1980-2016
This dataset is part of the National Water Census ongoing development of best estimates of daily historical water budgets for over 100,000 hydrologic units across the United States. In this release, estimates of total flow and snowmelt for each hydrologic unit are added to the already released estimates of actual evapotranspiration, snowpack water-equivalent storage, soil moisture...
Contemporary fire history metrics for the conterminous United States (1984-2025)(ver. 5.0, April 2026) Contemporary fire history metrics for the conterminous United States (1984-2025)(ver. 5.0, April 2026)
Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 41-year period (1984-2024). The Landsat BA product was consolidated into a suite of...
Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity O-1-99-SC Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity O-1-99-SC
Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in June of 1999 in the coastal zone and continental shelf between Los Angeles and San Diego, offshore California (USGS field activity O-1-99-SC). In 2021 these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California's continental margin.
Macroinvertebrate community and sediment toxicity data from the Eighteenmile Creek Area of Concern, New York, 2021 Macroinvertebrate community and sediment toxicity data from the Eighteenmile Creek Area of Concern, New York, 2021
A data release containing information on benthic macroinvertebrate communities and sediment toxicity in the Eighteenmile Creek Area of Concern and a nearby reference area at Oak Orchard Creek. Bed sediments were collected during summer 2021 at 8 sites on Eighteenmile Creek and at 6 sites on Oak Orchard Creek using a petite Ponar dredge for macroinvertebrate identification and sediment...
Sampling Data for Eelgrass (Zostera marina) in Norma Bay, Izembek Lagoon, Alaska, 1987 Sampling Data for Eelgrass (Zostera marina) in Norma Bay, Izembek Lagoon, Alaska, 1987
These data are related to surveys of eelgrass beds in Norma Bay, Izembek Lagoon, Alaska. The table provides eelgrass shoot lengths and density measurements from sampling in September 1987.
Fisheries-dependent data for Cisco in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron between 1929 and 1970 Fisheries-dependent data for Cisco in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron between 1929 and 1970
This data release presents part of historical fisheries-dependent data for Cisco (Coregonus artedi) in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron collected by scientists from U.S. Geological Survey's Great Lakes Science Center, including three tables for monthly Cisco-catch and fishing-effort data and two tables for biological data of Cisco individuals. The monthly Cisco...
Sediment Deposition on Floodplains and Point Bars of Powder River in Southeastern Montana from 1979 through 2017 Sediment Deposition on Floodplains and Point Bars of Powder River in Southeastern Montana from 1979 through 2017
This data release consist of the annual sediment depositional volume at five floodplain and five point bar sites on Powder River in southeastern Montana from 1979 through 2017. These 10 sites are a subgroup of a larger group of cross-sections established in 1975 and 1977 to monitor the channel changes along a 90-kilometer reach of Powder River. In addition to the sediment deposition data...
Electric Resistivity Tomography (ERT) surveys conducted near campgrounds on the Buffalo National River, Arkansas Electric Resistivity Tomography (ERT) surveys conducted near campgrounds on the Buffalo National River, Arkansas
Karst environments present many challenges to agencies and engineers attempting to work in these landscapes, particularly towards building infrastructure. The interconnectivity of karst hydrologic systems means that activities occurring on the surface of a karst landscape can have an impact on water quality and quantity. Additionally, soil thickness in karst landscape is often highly...
Possible Cattle Access Points on Select Streams within the Smith Creek Watershed Derived from 2018 NAIP Imagery Possible Cattle Access Points on Select Streams within the Smith Creek Watershed Derived from 2018 NAIP Imagery
This data release contains one shapefile describing cattle access to a total of 36 different sub basins within the Smith Creek Watershed located in Virginia and West Virginia. This data release identifies areas in satellite imagery where cattle were observed to have access to the stream (confirmed access), areas where cattle exist, and are not fenced off from the stream (unrestricted...
