From 1983 through 1991, the National Geophysical Data Center (now the National Centers for Environmental Information)(now the National Centers for Environmental Information (NCEI)) compiled a comprehensive, computerized bibliography and geochemical database on offshore marine mineral deposits. Construction of the bibliography and database was a cooperative effort with the Ocean Minerals and Energy Division of the National Ocean Service of NOAA, and the Office of International Activities and Marine Minerals (INTERMAR) of the Minerals Management Service. Additions to the bibliography and database stopped in 1991. The 1992 NOAA and MMS Marine Minerals CD-ROM Data Set, produced by NGDC (now NCEI) and partially funded by INTERMAR, contains the entire NCEI Marine Minerals Bibliography and Geochemical Database and several data files compiled by other organizations.
The NCEI Marine Minerals Bibliography includes references to present-day marine deposits of ferromanganese nodules and crusts, placers/heavy minerals, phosphorites, and polymetallic sulfides. The final bibliography contains citations from 1831 through 1990. Information in the file includes author, title, publication/serial title, date of publication, language, etc., as well as several key word categories including geographic area and type of study conducted. Subject key words are annotated with "general" or "technical" to indicate whether a subject was mentioned briefly, or was explored in detail. Key words also include the names of each mineral and each element mentioned in the article. Geographic keys include ocean or sea name, numeric designators for the ocean/sea, the name of any pertinent geographic feature, US exclusive economic zones (e.g. East Coast), and geologic setting.
The Marine Minerals Geochemical Database contains chemical analyses and auxiliary information on present-day marine deposits of primarily ferromanganese nodules and crusts but also contains some data for heavy minerals. Sources of data include the historic Scripps Institution of Oceanography (SIO) manganese nodule analysis file, the Centre National Pour l'Exploitation des Oceans (CNEXO) ferromanganese nodule analysis file, ferromanganese crust data compiled by US Geological Survey, and data coded at NCEI from the scientific literature. The ferromanganese nodule/crust portion of the database contains over 140,000 elemental/oxide analyses. Approximately 1,400 heavy mineral analyses coded at NGDC (now NCEI) are included, as well as data from the US East Coast contributed by the US Geological Survey.
