Data Analysis 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.

The National Water Information System (NWIS) Mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.

The NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The Portal contains current and historical data including water levels, water quality, lithology, and well construction.

StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. Available information varies from state to state.

The USGS WaterWatch Toolkit provides online tools that allow users to search USGS sites in various ways; create a variety of maps, graphs, charts, animations, and tables; perform a variety of streamflow analyses, and retrieve summary statistics.

Using the SPARROW (SPAtially-Referenced Regression on Watershed Attributes) model, long-term mean annual conditions for dissolved-solids sources, loads, and yields were predicted for nearly 66,000 stream reaches and their corresponding incremental catchments that drain the Nation.

USGS Flood Inundation Maps, along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.
