Annotated record of the detailed examination of Mn deposits from SESAM cruise stations

The cores and dredges described at this site were taken on the SESAM cruise from 30 April until 10 June 1976 by the Muséum National d'Histoire Naturelle from the R/V Marion Dufresne. A total of 55 cores, dredges and camera stations were recovered and are available at MNHN for sampling and study.

Annotated record of the detailed examination of Mn deposits from seventh cruise of the Carnegie (1928-1929)

The Carnegie, on its seventh cruise and last cruise, collected seventy-five samples of deep-sea deposits in the southeastern and the north Pacific. This report contains an account of the general character of the deep-sea samples collected and of the distribution of the various deposit types, together with the results of chemical, mechanical, X-ray, and other types of analyses. As indicated in the text, many of the analyses were carried out in whole or in part by other investigators.

Annotated record of the detailed examination of Mn and phosphate deposits from GOS74 Expedition stations

The purpose of the cruise was to map the manganese rich pavements of the Blake Plateau area which had been extensively investigated by ships of the Woods Hole Oceanographic Institution since 1956. From August until September 1965, 112 sites were sampled from R/V Gosnold on a joint USGS-WHOI expedition. At most of the stations on the Blake pavement, large slabs of manganese were recovered along with phosphate rich nodules.
