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.

Estimated Streamflow Using Satellite Data for Selected Rivers in Alaska Estimated Streamflow Using Satellite Data for Selected Rivers in Alaska
This dataset provides estimated Remote Sensing Streamflow (RSQ) data at selected river reaches in Alaska. Reach-specific relations between satellite-derived water-surface elevation data and dynamic surface water extent data were used with a modified form of the Manning's streamflow equation to estimate streamflows. The streamflow estimates were used to create rating tables that define...
Monitoring Changes in Surface Elevation Using Deep Surface Elevation Table and Marker Horizon Data at the Nisqually River Delta, Washington Monitoring Changes in Surface Elevation Using Deep Surface Elevation Table and Marker Horizon Data at the Nisqually River Delta, Washington
Surface Elevation Tables and Marker Horizon (collectively SET-MH) datasets provide a unique opportunity to evaluate tidal marsh accretion rates compared with current and projected sea-level rise. SET is a tool that allows for accurate and repeatable measurements of marsh elevation, while Marker Horizon allows for the measurement of sediment that has deposited on top of the feldspar...
Earth Observation Assessment (EOA) 2023 Tableau Dashboard Data Earth Observation Assessment (EOA) 2023 Tableau Dashboard Data
The Earth Observation Assessment (EOA) is a Congressionally-directed periodic evaluation of the nation's civil Earth observation portfolio. This portfolio comprises both remote and in-situ sensors, operated by both the public and the private sector. The Earth Observation Assessment measures the effectiveness of the civil Earth observation system in meeting federal government objectives...
Shoreline data for Ocean Beach, San Francisco, California, 2004 to 2021 Shoreline data for Ocean Beach, San Francisco, California, 2004 to 2021
Beach shoreline positions were derived from 221 approximately monthly beach topography surveys from 2004 through 2021 at Ocean Beach in San Francisco, California. Shoreline shapefiles for local Mean High Water (1.619m NAVD88) and local Mean Sea Level (0.975m NAVD88) were created from each survey.
Community level traits of invaded plant communities in the United States Community level traits of invaded plant communities in the United States
Data were compiled from large trait databases for functional above and belowground traits (e.g. specific leaf area, specific root length, etc) of plants in communities across the United States along with information about the degree to which invasive species dominate those communities.
Computational notebook to plot offset measurements along strike-slip faults Computational notebook to plot offset measurements along strike-slip faults
Summary: This computational notebook is intended to visualize any dataset of offset measurements along a fault, including datasets for single or multiple earthquakes. It is used to plot recent, geomorphic, and synthetic offset measurements for the companion manuscript: Limited preservation of strike-slip surface displacement in the geomorphic record by N.G. Reitman, Y. Klinger, R. Briggs...
Detailed Grain-Size Data of Estuarine, Barrier Island, and Shoreface Environments Around Dauphin Island, Alabama, USA Detailed Grain-Size Data of Estuarine, Barrier Island, and Shoreface Environments Around Dauphin Island, Alabama, USA
In 2015, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted sediment sampling surveys on and around the barrier islands of Dauphin Island and Little Dauphin Island, Mobile County, Alabama (AL). The study investigated the surficial sediment surrounding Dauphin Island and surrounding environments to inform sediment transport...
Atlantic and Gulf Coastal Plain foraminifera: Digitized and updated taxonomy of Thomas G. Gibson’s census data Atlantic and Gulf Coastal Plain foraminifera: Digitized and updated taxonomy of Thomas G. Gibson’s census data
This foraminiferal census data was originally produced by USGS research Geologist Thomas G. Gibson in the 1960s through the early 2000s. The census data here documents evidence of foraminifer populations found in sediment samples extracted from four cores from the Atlantic Coastal Plain and the Gulf Coastal Plain. These samples represent Pliocene, Middle- Miocene and Paleocene-Eocene...
Potential Corrosivity Scores of Untreated Groundwater in Louisiana Potential Corrosivity Scores of Untreated Groundwater in Louisiana
Four indices—the Langelier Saturation Index (LSI), Ryznar Stability Index (RSI), Puckorius Scaling Index (PSI), and the Potential to Promote Galvanic Corrosion (PPGC) — in addition to an analysis which normalized the results from the existing indices, the Combined Index (CI), were used to assess the potential corrosivity of groundwater in Louisiana. The text file 'potential corrosivity...
Magnetotelluric and TEM Data from the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2, 2020 Magnetotelluric and TEM Data from the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2, 2020
This data set consists of 19 wideband magnetotelluric (MT) and 23 transient electromagnetic (TEM) soundings collected by the U.S. Geological Survey in June 2020 as part of the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2 project. Each MT station had 4 components, 2 orthogonal magnetic induction coils and 2 horizontal orthogonal electric dipoles. Data were...
Cheatgrass and Medusahead annual Phenology extraction in Snake River Plain and Northern Basin and Range Cheatgrass and Medusahead annual Phenology extraction in Snake River Plain and Northern Basin and Range
Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally. The cheatgrass and medusahead phenology in the Snake River Plain (SRP) and Northern Basin and Range (NBR) based on 30m near seamless Harmonized Landsat and Sentinel-2 (HLS) Normalized Difference...
Hawaiian Volcano Observatory Earthquake Catalog for the region around Mauna Loa 2009-2023 Hawaiian Volcano Observatory Earthquake Catalog for the region around Mauna Loa 2009-2023
Catalog datasets in support of publication, "A Decade of Precursory Seismicity at Mauna Loa: 2013-2022". The earthquake catalogs begin April 1, 2009 and extend to January 1, 2023. The entire dataset has been generated with the ANSS Quake Management System (AQMS), which has the real-time software package Earthworm at its core. Automated and reviewed locations use the Hypoinverse location...
