SUMMARY

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. The four files include data source, latitude/longitude, sampling device, water depth, nodule type, and weight percentages of selected elements. Files of additional elemental analyses, and bibliographic references are also included. The SIO data are also included in the NGDC marine minerals data base.

SEARCHABLE DATA INVENTORY

NGDC/WDC GMG, Boulder archives a wide variety of digital marine geology data collections, paper reports, microfilm, etc. containing sediment and hardrock data. Many of the digital files are available for direct download. Sample-by-sample inventory information for all data, regardless of format available from NGDC are fully searchable through the marine geology inventory (GEOLIN).
