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.

Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across the Western U.S. 1985-2021

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across the western U.S. using Landsat imagery from 1985-2021. The RCMAP product suite consists of nine fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, and tree, in addition to the te

Compilation of total organic carbon and pyrolysis analysis data for Cretaceous marine shales in the Raton Basin-Sierra Grande Uplift Province, Colorado and New Mexico

This compilation presents total organic carbon and pyrolysis analysis data for the Pierre Shale, Niobrara Formation, and other Cretaceous marine shales in the Raton Basin-Sierra Grande Uplift Province. The data was used to characterize these potential source rock intervals in support of the oil and gas resource assessment in the province. The data was compiled from the publicly available files at

Hydroacoustic data from uncrewed surface vehicle (USV) overtakes in Lakes Huron and Michigan, 2021

These data were derived from hydroacoustic data collected by uncrewed surface vehicles (USVs) and powered research vessels. The powered vessels overtook the USVs in Lakes Huron and Michigan to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into three depth groups (epilimnion, metalimnion, hypolimnion) for analysis. Each drone transect was b

Connectivity and Bottlenecks of Habitat Patches along the United States terrestrial coastline of the Great Lakes

This dataset maps the connectivity and bottlenecks among habitat patches within a six-kilometer ribbon along the United States terrestrial coastline of the Great Lakes. Each pixel represents the relative value that cell contributes to connectivity between and among habitat patches. When aggregated the pixel values produce a map of all possible pathways between habitat patches providing the end use

Connectivity and Bottlenecks of Protected Areas along the United States terrestrial coastline of the Great Lakes

This dataset maps the connectivity and bottlenecks among protected areas within a six km ribbon along the terrestrial coastline of the U.S. Great Lakes. Each pixel represents the relative contribution that cell provides to connectivity between and among the protected areas. When aggregated the pixel values produce a map of all possible pathways between protected areas, providing the end user with

LANDFIRE 2014 (140) NGDA Products

LANDFIRE (LF) 2014 incorporates landscape change and disturbances, such as wildland fire, fuel and vegetation treatments, insects and disease, storm damage, and invasive plants that occurred in 2013 and 2014. This update includes: responses to vegetation successional change in forested types revisions to address discrepancies between map products and known field conditions The LF 2014 update als

Water quality and contaminants in stream surface waters collected in the Shenandoah Valley, 2021

The data presented in this data release includes 11 field/water quality parameters, concentrations of 16 nutrients/anions, dissolved organic carbon, 14 organic contaminants, net estrogenicity concentrations, and 51 inorganic constituents in surface water collected twice from 28 stream sites and collected once from 2 stream sites in the Shenandoah Valley (Virginia and West Virginia, USA), in the su

Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute pesticide toxicity tests

Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute toxicity tests with pyrethroid pesticides. Exposure and recovery water quality data are also included for quality assurance purposes.

Evaluation of DNA yield from various sources for use in single nucleotide polymorphism panels

Genetics studies are used by wildlife managers and researchers to gain inference into a population of a species of interest. To gain these insights, micro-satellites have been the primary method, however, there currently is a shift from micro-satellites to single nucleotide polymorphisms (SNPs). With the DNA requirements being different, an investigation into which samples can provide adequate DNA

Point Location of Myotis septentrionalis Echolocation Passes in Eastern North Carolina and Virginia

These data are the location and date of collection of endangered northern long-eared bat Myotis septentrionalis echolocation passes when the automated bat identification software assessed species presence at a maximum likelihood estimator p-value of less than or equal to 0.05 consistent with the U.S. Fish and Wildlife Service monitoring guideline standards.

Data from the manuscript: Direct evidence for fluid pressure, dilatancy, and compaction affecting slip in isolated faults

Earthquake instability occurs as a result of strength loss during sliding on a fault. It has been known for over 50 years that fault compaction or dilatancy may cause significant weakening or strengthening by dramatically changing the fluid pressure trapped in faults. Despite this fundamental importance, we have no real understanding of the exact conditions that lead to compaction or dilation duri

Data from the manuscript: Electrical properties and anisotropy of schists and fault rocks from New Zealand’s Southern Alps under confining pressure

Electrical resistivity measurements of Alpine Fault, NZ outcrop samples saturated with 0.1 M KCl brine and tested at confining pressure of 5 to 200 MP at room temperature.
