        <gco:CharacterString>The Scripps Institution of Oceanography compiled descriptions of sediment samples related to ferromanganese deposits, funded through the International Decade of Ocean Exploration (IDOE) and Project MAGNOD by the National Science Foundation, as part of the SIO world sediment data bank. Descriptions are for 41 cores, 136 grab/dredges, and 19 box cores  primarily from the East Central Pacific. Data include lithology, percent CaCO3, constituents by grain size, organic material/fossils, ages, other features, and minerals. Station and inventory information are included. These data are included in ASCII form on the NOAA and MMS Marine Minerals CDROM data set released by the former National Geophysical Data Center (NGDC)(now part of NCEI) in October of 1992. They are also available for direct download from the NCEI web site.</gco:CharacterString>
