Chemical composition of manganese nodules and crusts from the Atlantic and Pacific oceans

The cores and dredges described are taken during the R/V New Horizon RISE III Expedition from April until May 1979 by the Scripps Institute of Oceanography. A total of 36 cores and dredges were recovered and are available at Scripps Institute of Oceanography for sampling and study. The goal of this expedition was to accomplish the field work of a combined field and laboratory study aimed at increasing the understanding of the origins and development of young oceanic volcanoes.
