Indian Ocean Geology and Biostratigraphy – Studies Following Deep–Sea Drilling Legs

Published by the American Geophysical Union as part of the Special Publications Series.

The Drilling Vessel GLOMAR CHALLENGER entered the Indian Ocean when she left Darwin, Australia on January 13, 1972. She traveled around that Ocean in a counterclockwise fashion drilling 72 holes at 64 sites during 7 cruises over all the major ridges and basins from the Red Sea to the Antarctic continent. She finished her work there when she eventually arrived at Christchurch, New Zealand on February 27, 1973. During this time nearly 30 km of seafloor was penetrated and much of that material was recovered and studied and is archived at the Deep Sea Drilling Project core depository.
