        abstract:  From 1983 through 1992, the National Oceanic and Atmospheric Administration (NOAA) National Geophysical Data Center (NGDC) compiled a comprehensive, computerized bibliography of offshore marine mineral deposits as a cooperative effort with the Ocean Minerals and Energy Division of the NOAA National Ocean Service, and the Office of International Activities and Marine Minerals (INTERMAR) of the Minerals Management Service (MMS). In October of 1992, the NOAA and MMS Marine Minerals Bibliography (MMBIB) was released as a compact disc. The bibliography includes over 17,000 citations of references to sea floor deposits of ferromanganese (polymetallic) nodules and crusts, placers/heavy minerals, phosphorites, and polymetallic sulfides published from 1831 through 1990. References include key word categories indicating 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 NOAA and MMS Marine Minerals CD-ROM Data Set, produced by NGDC and partially funded by INTERMAR, contains the entire NGDC Marine Minerals Bibliography and Geochemical Database and several data files compiled by other organizations. The bibliography is searchable on-line on NGDC's web server. The NOAA and MMS Marine Minerals Bibliography and geochemical database was incorporated by the International Seabed Authority (ISA) into their online compilation, which uses the NGDC MMBIB identification system for references.

        supplementalInformation:  In July of 1992 NGDC transferred, on permanent loan, the collection of documents collected for the NGDC Marine Minerals Bibliography to the Marine Minerals Technology Center (MMTC), Ocean Basins Division, in Hawaii to facilitate public access to the collection. (Marine Minerals Technology Center, Ocean Basins Division, University of Hawaii, Look Laboratory, 811 Olomehani Street, Honolulu, HI 96814, 808-522-5611). Conditions of transfer were that the collection will be kept as a discrete set, filed according to the MMBIB number, in order to facilitate its use with the computerized NGDC Marine Minerals Bibliography and Geochemical Data Base, and will remain in the public domain, with free access (not duplication) provided to all interested parties. Publications generated using the collection are required to cite the NGDC Marine Minerals Bibliography as a source of information, including reference to NOAA/NGDC, and to the project sponsors, MMS/INTERMAR and NOAA/NOS/OMED. The United Nations-sponsored International Seabed Authority (ISA) has reworked most of the geochemical data from this CD-ROM set and is also updating/maintaining the bibliography with enhancements. Both are available online through the ISA central data repository.

            name:  Deposit type
            definition:  Type: Refers to the type of deposit being described on this form - more than one form is required (1 per type) if more than one relevant type of deposit is treated in the article. Deposit - Refers to an actual concentration of Manganese (crust, pavement, micronodules, nodules, etc.), Phosphorite (nodules, layers, massive deposits), Placer (Placer or Heavy Mineral study on a continental shelf or other insular margin less than 200 meters water depth - deposits where the only heavy mineral mentioned is pyrite do not qualify as heavy mineral/placer), or Polymetallic Sulfides (veins, stockwork, layers, massive sulfides, etc.) associated with hydrothermal systems in the ocean. Where the sulfides are finely disseminated in a hard rock rather than isolated as significant veins, etc., it is not considered to be a polymetallic sulfide deposit for purposes of this bibliography. This does not include disseminated Mn or Sulfides in sediments (including pyrite) unless closely associated with a hydrothermal vent or ridge system. It also does not include mn, sulfate, sulfide, phosphorus or phosphate dissolved in the water column, or phosphorus/phosphate disseminated in sediment. 'Phosphorite' is a specific term referring to a rock of higher than a certain % phosphorus - we don't draw a line because the % varies. Phosphorus is an element, and phosphates are a group of compounds - we are interested in 'phosphorites' or 'phosphate-rich' rocks, sand, gravel, pebbles, cobbles, crusts, or layers.
