Data Access Tools

The National Petroleum Reserve, Alaska, (NPRA) Legacy Data Archive represents one of the largest geological and geophysical data sets held by the U.S. Geological Survey. Two exploration programs by the U.S. Navy and USGS collected over 12,000 line miles of seismic data and drilled 28 wells. These programs generated a vast amount of data, analyses, and documents, much of which is presented h

The World Coal Quality Inventory (WOCQI) Spatial Viewer allows users to select a country and download underlying data associated with countries that were working collaboratively to sample and inventory coal.

This viewer allows users to see the location and underlying data associated with NCRDS USTRAT data points. The NCRDS Spatial Viewer was expanded to display data from the USCHEM and USCOAL databases in FY2011.

Data containing geodetic location, field observations, sample analyses, bed thickness; lithology; depth of burial, moisture, ash, and sulfur content, heat value, and major-, minor-trace-element contents.

The St. Petersburg Coastal and Marine Science Center (SPCMSC) Core Viewer is an interactive web mapping application of the center’s geologic core and samples database. The database contains a comprehensive inventory of geologic (coral, coral reef, limestone, and sediment) cores and samples collected, analyzed, published, and/or archived by, or in collaboration with SPCMSC.

The National Archive of Marine Seismic Surveys (NAMSS) is a marine seismic reflection data archive consisting of data acquired by or contributed to U.S. Department of the Interior agencies. The USGS is committed to preserving these data on behalf of the academic community and the nation. Data are provided with free and open access.
