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.

'Viva' native plant material data in support of restoration and conservation 'Viva' native plant material data in support of restoration and conservation
These data were compiled to investigate the evolutionary history of Hilaria jamesii, Hilaria mutica, and Hilaria rigida. The data release consists of two tab delimited text files that may be used to infer population structure (viva_structure.stru) or relationships among sampling localities (viva.phylip). Files record genetic variation on an individual (.stru) or sampling locality (...
Supplemental Evapotranspiration Gap-filled Datasets from Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18 Supplemental Evapotranspiration Gap-filled Datasets from Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18
This USGS data release represents supplemental tabular data for an annual groundwater discharge by evapotranspiration (ET) from areas of spring-fed riparian vegetation, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18. The raw ET dataset contained multiple data gaps that were simulated and gap-filled with the water-level model utility in SeriesSEE, a USGS developed Microsoft...
Population genetic and climatic variability data across western North America, 1915-2015 Population genetic and climatic variability data across western North America, 1915-2015
Environmental Analysis Data: These data were compiled to investigate the complex interactions between environmental gradients and geographic distance across the Intermountain West of the western United States. Due to complex topography, physiographic heterogeneity, and complicated relationships with large bodies of water, spatial autocorrelation of environmental similarity may be...
Locality based caddisfly (Hydropsyche oslari) sampling data and CO1 sequences from the southwestern United States, 2013-2016 Locality based caddisfly (Hydropsyche oslari) sampling data and CO1 sequences from the southwestern United States, 2013-2016
These data were compiled for a mtDNA (CO1 gene) analysis of net-spinning caddisflies (Hydropsyche oslari) in the Colorado River Basin of the western United States. They were incorporated in a study that investigated the genetic diversity and population structure of H. oslari relative to the river network structure in the Upper and Lower Colorado River Basins. The data were collected from...
USGS National and Global Oil and Gas Assessment Project - Appalachian Basin Province, Middle Devonian Marcellus Shale Assessment Units and Input Data Forms USGS National and Global Oil and Gas Assessment Project - Appalachian Basin Province, Middle Devonian Marcellus Shale Assessment Units and Input Data Forms
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered gas resources in the Middle Devonian Marcellus Shale of the Appalachian Basin Province, 2019. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the...
Potomac River ADCP Bathymetric Survey, October 2019 Potomac River ADCP Bathymetric Survey, October 2019
Water-penetrating LiDAR technology was used to remotely sense bathymetric elevation data as part of a spatial data acquisition on the Potomac River. In support of this effort, a bathymetric survey with a boat-mounted acoustic Doppler current profiler (ADCP) was conducted in the study area on October 21-24, 2019. Global Navigational Satellite Systems (GNSS) were used to concurrently...
