Data and Tools

Science Datasets

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.

Geochemical Characteristics of the Conterminous United States: % Nitrogen

This raster depicts the percentage of lithological nitrogen (N) content in surface or near surface geology. We derived these rasters by calculating the average percent N content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-...

Geochemical Characteristics of the Conterminous United States: % Na2O

This raster depicts the percentage of lithological sodium oxide (Na2O) content in surface or near surface geology. We derived these rasters by calculating the average percent Na2O content for each map unit in combined surficial-bedrock geologic maps.

The Kiowa core, a continuous drill core through the Denver Basin bedrock aquifers at Kiowa, Elbert County, Colorado

The Kiowa core was obtained as a component of the Denver Basin Project, a cooperative research effort to study the evolution of the Denver Basin, Colorado. The Kiowa core provides a virtually continuous stratigraphic record of the Upper Cretaceous and lower Tertiary strata of the Denver Basin.

Land Disturbance Associated With Oil and Gas Extraction in Southwestern Wyoming, 2012

Gas field infrastructure elements contributing to land disturbance located in four gas fields (Continental Divide – Creston – Blue Gap (CCB), Jonah, Moxa Arch, and Pinedale Anticline Project Area) in southwestern Wyoming were collected as polygon features in ArcGIS. Classes included four types of roads, well pads (active and abandoned), residual disturbance associated with...

Space Use Index (SUI) for the Greater Sage-grouse in Nevada and California (August 2014)

SPACE USE INDEX CALCULATIONLek coordinates and associated trend count data were obtained from the 2013 Nevada Sage-grouse Lek Database compiled by the Nevada Department of Wildlife (NDOW, S. Espinosa, 9/10/2013). We queried the database for leks with a ‘LEKSTATUS’ field classified as ‘Active’ or ‘Pending’. Active leks comprised leks...

Sub regions for Greater Sage-grouse in Nevada and California (August 2014)

Spatial associations between marked sage-grouse and existing PMU boundaries (Nevada Department of Wildlife, 2014) were used as an initial starting point for delineating subregions for habitat selection analyses and naming conventions across Nevada and northeastern California (fig. 3). Ultimately, the data were partitioned into 19 subregions based on movement patterns of individual radio-marked...
