Abstract
Manganese nodule elemental chemical data added to the scripps institution of oceanography (sio) sediment data bank during the grant year are listed. The data include composition of 330 samples analyzed at sio and 712 analyses extracted from the literature. Data summaries for potential resource areas in the north equatorial Pacific are updated to include information obtained in 1978. A study of deep-tow seafloor photos is reported summarizing nodule distribution patterns for a 500-km2 area at about 11 deg n, 140 deg w. Seafloor concentration and coverage data are calculated from the photos. A preliminary resource evaluation of the Indian Ocean reveals no first-generation mine sites. However, five areas that can be considered possible mineral resource areas are delineated. These areas cover about 3.9 million km2.
