About the links above:

Several digital data sets have their own interfaces. Links to these interfaces are in the table above. Direct links to additional static digital data files are also available, in addition to access via the geology inventory.

The NGDC Marine Geology Inventory provides searchable access to all marine geology data archived by, and available through NGDC, regardless of data format, and direct download of most digital data files.

Inventory information is included for several hundred reports/data sets including data from over 130,000 seafloor samples. Data sources include academic institutions, NOAA, other US government agencies, foreign countries, and a few private companies.

Most geologic reports are in .pdf form, including oversize charts, and are viewable and downloadable through the Inventory. A total of over 70,000 pages (over 8 gigabytes of scanned images) are available online.

If you have problems directly searching the inventory using a web browser, please call/email NGDC with search requests. Searches are performed free of charge.
