The Scripps Institution of Oceanography (SIO) compiled data on the geochemistry of
marine ferromanganese nodules, funded by the U.S. National Science Foundation (NSF),
as part of the International Decade of Ocean Exploration (IDOE). Data were collected
under the Manganese Nodule (MNNOD) and Deep Ocean Mining Environmental Studies (DOMES)
programs. This SIO compilation includes data from 442 dredge and grab samples and
419 cores collected at 861 sea floor locations worldwide. Additional, non-IDOE, data
compiled by SIO are not included. Data were abstracted by SIO staff from the literature,
and other sources, including personal communications. The five files include data
sources, latitude/longitude, sampling device, water depth, nodule type, weight percentages
of selected elements, and bibliographic references. These data are also available
as part of the NOAA and MMS marine minerals database and corresponding NOAA and MMS
Marine Minerals CDROM data set released by NOAA in 1992. |
