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.

Daily reference and potential evapotranspiration, and supporting meteorological, solar insolation, and blue-sky albedo, Florida, 2019 Daily reference and potential evapotranspiration, and supporting meteorological, solar insolation, and blue-sky albedo, Florida, 2019
Potential evapotranspiration (PET), and reference evapotranspiration (ETo) are estimated at an approximately 2-kilometer (approximately 0.019 degrees longitude and 0.018 degrees latitude) spatial grid and daily time-scale from January 1, 2019 to December 31, 2019 for the entire State of Florida. PET and ETo were computed on the basis of solar radiation, meteorological data (minimum...
Synthetic streamflow regressions and daily mean streamflow estimates at three sites on the Yankee Fork Salmon River near Clayton, ID, Water Years 2012-2019 Synthetic streamflow regressions and daily mean streamflow estimates at three sites on the Yankee Fork Salmon River near Clayton, ID, Water Years 2012-2019
To provide daily mean streamflow values at ungaged (partial-record) sites within the Yankee Fork Salmon River watershed, the U.S. Geological Survey (USGS), in cooperation with U.S. Bureau of Reclamation, used discharge measurements at three partial-record sites and related those measurements to a nearby USGS real-time streamgage (index site). Daily mean streamflow was estimated by...
Whole-rock chemistry of Hole G core samples from the San Andreas Fault Observatory at Depth (SAFOD), California Whole-rock chemistry of Hole G core samples from the San Andreas Fault Observatory at Depth (SAFOD), California
We present whole-rock geochemical analyses of 27 Phase 3 core samples obtained from Hole G of the San Andreas Fault Observatory at Depth, which crosses the creeping section of the San Andreas Fault ~14 km NW of Parkfield, California. These new data will essentially double the published whole-rock chemical dataset for the SAFOD Hole G core. Two, meters-wide zones of foliated gouge where...
Data on the Enrichment and Isolation of the Acetylenotrophic and Diazotrophic Isolate Bradyrhizobium sp. strain I71 (ver 2.0, September 2022) Data on the Enrichment and Isolation of the Acetylenotrophic and Diazotrophic Isolate Bradyrhizobium sp. strain I71 (ver 2.0, September 2022)
Acetylene (C2H2) is a molecule rarely found in nature, with few known natural sources, but acetylenotrophic microorganisms can use acetylene as their primary carbon and energy source. As of 2018 there were 15 known strains of aerobic and anaerobic acetylenotrophs, however we hypothesized that there may be yet unrecognized diversity of acetylenotrophs in nature. In this study, we expanded...
USGS National and Global Oil and Gas Assessment Project - Northern Alaska Province, Western North Slope Assessment Unit Boundaries and Assessment Input Data Forms USGS National and Global Oil and Gas Assessment Project - Northern Alaska Province, Western North Slope Assessment Unit Boundaries and Assessment Input Data Forms
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources of strata older than the Torok Formation of the Western North Slope in the Northern Alaska province. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The...
Glaciers of Glacier National Park Repeat Photography Collection Glaciers of Glacier National Park Repeat Photography Collection
The “Glaciers of Glacier National Park Repeat Photography Collection” is a compilation of photographs documenting the retreat of glaciers in Glacier National Park, Montana, U.S.A. (GNP) through repeat photography. The collection is comprised of 58 image pairs, resulting from twenty-two years of U.S.Geological Survey (USGS) field excursions (1997-2019) for the purpose of photographically
