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.

Annotated record of the detailed examination of Mn and phosphate deposits from GYRE 82-11 Expedition stations

The purpose of the expedition was to test new techniques to determine thickness, distribution and quality of mineral deposits on the Blake Plateau with special reference to manganese nodules and manganese-phosphate pavements.

Annotated record of the detailed examination of Mn deposits from R.R.S. "Discovery" Cruise 2 stations

This report gives a comprehensive general description of the scientific activities of Cruise 2 of R. R. S. 'Discovery'. These were largely geological and geophysical and were part of the British contribution to the International Indian Ocean Expedition. In addition to the thirteen geophysicists and geologists on board, there were five scientists involved in ocean chemistry, temperature measurements and ornithology making continuous observations - their accounts are also included. The report of a geological expediton ashore in the Seychelles is given in section 6.
