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.

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...
Digital database of the geologic map of the southern Stillwater Range, Nevada Digital database of the geologic map of the southern Stillwater Range, Nevada
This data set is a geospatial database for the 1:24,000 scale Geologic Map of the Southern Stillwater Range, Nevada (John and others, 2024). It contains all the geologic spatial information and text unit descriptions from the printed map, in the Geologic Map Schema (GeMS) format for digital geologic maps maintained by the USGS’ National Cooperative Geologic Mapping Program (NCMGP). Base...
