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.

Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2022 (ver 6.0, July 2022)

These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-weekly release contains four fractional cover maps along with their corresponding confidence maps f

Data Release for Secondary Hydrogeologic Regions of the Conterminous United States (ver. 2.0, June 2022)

The U.S. Geological Survey (USGS) previously identified 62 Principal Aquifers (PAs) in the U.S., with 57 located in the conterminous states. The USGS characterized areas outside of PAs as “other rocks;” other rocks account for about 40% of the area of the conterminous states. This paper subdivides the large area identified as other rocks into Secondary Hydrogeologic Regions (SHRs). SHRs are define

qPCR Results for An Assessment of Naegleria fowleri in Grand Teton National Park, Wyoming

In 2016, a multidisciplinary team from the U.S. Geological Survey Wyoming-Montana Water Science Center, National Park Service, The Centers for Disease Control and Prevention, and Montana State University’s Department of Microbiology and Immunology in cooperation with the Teton Conservation District, initiated a small study to document the presence or absence of Naegleria fowleri at several hot spr

Invertebrate, fish, and habitat data collected within the greater Fountain Creek Basin, Colorado (version 4.0, March 2024)

Invertebrate, fish, and habitat data were collected as part of a cooperative project that began in 2002 between the U.S. Geological Survey, Colorado Springs Utilities, and Colorado Springs Engineering. Other entities have contributed to the project over the years including Colorado Parks and Wildlife. Data were primarily collected from up to 35 sites – 33 sites within the Fountain Creek Basin but

A geodatabase of Surficial Geology of the Allentown 30x60-Minute Quadrangle in Pennsylvania digitized from the original map of Braun, 1996

This Scientific Data Release is a spatial geodatabase representation of Braun, D. D., 1996, Surficial geology of the Allentown 30x60-minute quadrangle: Pennsylvania Geological Survey, 4th ser., Open-File Report 96-48, 17 p., 1 map, scale 1:100,000. These geospatial data depict surficial geologic materials in the Pennsylvania portion of the Allentown 30 x 60-minute quadrangle in eastern Pennsylvani

MODFLOW-OWHM model used to simulate groundwater flow and evaluate storage in the Lucerne Valley Groundwater Basin, California

A three-dimensional groundwater flow model, MODFLOW-OWHM, was developed to provide a better understanding of the hydrogeology of the Lucerne Valley Groundwater Basin, California. The model was used to investigate the historical groundwater storage loss and subsidence associated with anthropogenic groundwater demands. The model was calibrated to 1942 through 2016 conditions. This USGS data release

Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region

The lower Paleogene Wilcox Group crops out around the northern edge of the Gulf of Mexico Basin and is a major coal-bearing unit and a primary oil and gas producer in the lower Paleogene section of the Gulf Coast region. The outcrop distribution of the Wilcox Group and other coal-bearing strata of the Gulf Coast region was compiled as part of a U.S. Geological Survey National Coal Assessment (Warw

Peregrine Falcon (Falco peregrinus) mtDNA and Microsatellite Genetic Data, Alaska, Canada and Russia, 1880-2012

This data set provides sample information, microsatellite genotype, and NCBI accession numbers for mitochondrial DNA sequences of peregrine falcons (Falco peregrinus) from North America and Russia.

Wetland vegetation and elevation of Arcadia Marsh, Michigan (1995-2010)

Vegetation sampling and elevation data were collected to characterize the sedge-grass meadow of Arcadia Marsh, Arcadia, Michigan (USA), a drowned river mouth wetland near Lake Michigan. Wetland vegetation community data were collected by quadrat sampling in 1995, 2002, and 2010 and topographic data were collected via GPS and LIDAR positional data in 2010.

Spatial mark-recapture and chew card rat data on Guam and Rota, 2018-2019

We provide four datasets: Mark recapture and trapping effort, Grid layout, Chew cards, and Trail camera validation. Mark recapture and trapping effort has one row for every live-trap night, including the unique grid identification code, date of trap check, cumulative rain amount from the 24-hr period before the trap check, unique trap identification, trap status, unique individual rat identificati

Database of Biodiversity, Habitat, and Aquatic Resource Quantification Tools Used for Market-based Conservation in the United States (ver. 2.0, June 2022)

This comprehensive database describes the core attributes of quantification tools developed for market-based conservation in the United States. It encompasses tools designed for compensatory mitigation, non-compensatory mitigation, and voluntary conservation/restoration programs. The dataset consists of 107 tools. Each tool's features are described using 33 attributes related to general, technical

Rarity and Climate Sensitivity index and components of 90 species of frogs and toads native to the conterminous United States (ver. 2.0, October 2022)

This dataset contains the components of and resultant Rarity and Climate Sensitivity (RCS) values for 90 species of frogs and toads native to the conterminous United States. The RCS metric uses point occurrences to describe area of occurrence, quantifies the variation of climate conditions within that area, and combines and scales the two for a multispecies assessment of intrinsic sensitivity to c
