- The Index to Marine Geological Seafloor Samples Also known as the Curators' Database, this is a cooperative effort among nineteen oceanographic institutions and governmental agencies to provide information on the contents of their collections of seafloor samples to researchers. More than 100,000 samples can be searched on-line by specifying any combination of institution, cruise, ship, collection date, water depth, sampling technique, or geographic location.
- Marine Minerals Bibliography and Geochemical Database A computerized bibliography and geochemical database on offshore marine mineral deposits. Primarily contains chemical analyses of present-day marine deposits of ferromanganese nodules and crusts (more than 140,000 analyses), but also includes some data for heavy minerals (approximately 1400 analyses). Analyses can be downloaded from the website or ordered on a CD.
- GEOROC Geochemical Database GEOROC (GEOchemistry of Rocks of the Oceans and Continents) is a searchable collection of more than 50,000 analyses from different tectonic settings. Queries can be made based on bibliography, tectonic setting, geography, chemistry, and petrography.
- Petrological Database of the Ocean Floor PetDB is a web-based data management system for geochemical and petrological sample-based data. On-line queries can be made by specifying location, expedition/cruise, sample characteristics, literature reference, or sought chemical value(s).
