National Coal Resources Data System (NCRDS)

The National Coal Resources Data System (NCRDS) began as a cooperative venture between the USGS and State geological agencies in 1975 and focused on the stratigraphy and chemistry of coal. The current component databases of NCRDS include: USTRAT, USCHEM, and USCOAL.

NCRDS USTRAT Spatial Viewer

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.

Coal Point-source and Chemical Data (COALQUAL)

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.

Geoscience Data Viewer Web Mapping Application

Map viewer of the St. Petersburg Coastal and Marine Science Center's published subsurface bathymetry, seismic reflection, side-scan sonar, and cores and sediment samples.

Core and Sediment Sample Database

Map viewer of St. Petersburg Coastal and Marine Science Center's core and samples database. Includes coral cores, sediment cores, and sediment samples.

IPOD Data Archive

The content available here represents an archive of a publication released in 1994 entitled International Phase of Ocean Drilling:  Seismic Line 1 Demultiplexed Data, Cape Hatteras to Mid-Atlantic Ridge.

National Archive of Marine Seismic Surveys (NAMSS)

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.

GAP/LANDFIRE National Terrestrial Ecosystems 2011 Map Viewer

The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. This dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program.  The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system.

Protected Areas Database of the United States (PAD-US) Map Viewer

The Protected Areas Database of the United States (PAD-US) Viewer provides a spatially explicit inventory that lets any user explore the protected areas network anywhere in the United States and allows them to easily use this inventory in conservation, land management, planning, recreation and other uses. 

National Biogeographic Map

The National Biogeographic Map (NBM) is a project of the Core Science Systems Mission Area. The project’s goal is to provide a platform for analysis of questions about what species are where, how well protected they are, how vulnerable they are to stressors, and what management options will have the greatest benefit for conservation of biodiversity.
