Base de Donnees Geochimiques des Depots Ferromanganesifers d'Origine Oceanique Lacustre et Fossile
|
|
The Centre National Pour l'Exploitation des Oceans (CNEXO) ferromanganese nodule analysis files consist of geochemical data from published reports pertaining to oceanic ferromanganese deposits, including Russian, since 1891. Data were compiled under the direction of J.M. Monget of Ecoles de Mines, Paris through 1976 and contain data for nearly 200 core, dredge, and grab samples. Data include method of analysis, oxide/item/element concentrations, location, water depth, sample lithology, and bibliographic references. The CNEXO data are also available as part of the NGDC marine minerals database and are offered on the NOAA & MMS Marine Minerals CD-ROM data set released by NGDC in October of 1992.

SIO Ferromanganese Nodule Analysis File
|
|
The Scripps Institution of Oceanography compiled data on the geochemistry of marine ferromanganese nodules as part of the International Decade of Ocean Exploration, funded by the National Science Foundation. The files were discontinued in 1981. The SIO files contain data from approximately 1,500 samples collected at 800 locations worldwide. Data were abstracted from the literature, and other sources.

SIO Manganese Nodule Sediment Description File
|
|
The Scripps Institution of Oceanography compiled descriptions of sediment samples related to ferromanganese deposits, funded through the IDOE, as part of the SIO world sediment data bank. Nodule description data are for approximately 200 core, dredge, and grab samples worldwide. Data include lithology, percent CaCO3, constituents by grain size, organic material/fossils, ages, other features, and minerals.

US Geological Survey Ferromanganese Crust Data Set
|
|
The USGS Ferromanganese Crust data set was compiled by F.T. Manheim and C.M. Lane-Bostwick of the US Geological Survey, Woods Hole, MA. The data set consists of tables corresponding the USGS Open-File Report 89-020 Chemical Composition of Ferromanganese Crusts in the World Ocean: A Review and Comprehensive Database. Data include excerpts from the SIO nodule file, the NGDC marine minerals data base, Japanese sources, a PhD thesis, analyses performed at the Bureau of Mines, and analyses performed at other laboratories under the direction of the USGS. These data are also included on the NOAA & MMS Marine Minerals CD-ROM data set released by NGDC in October of 1992.
