Scripps Institution of Oceanography Ferromanganese Nodule Analysis File - IDOE Portion
browse graphic 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 NGDC marine minerals database and corresponding NOAA & MMS Marine Minerals CDROM data set released by NGDC in 1992.
