Initial Reports of the Deep Sea Drilling Project - Volume 27

This volume covers Leg 27 of the cruises of the Drilling Vessel Glomar Challenger. Leg 27 of the D/V Glomar Challenger was the sixth cruise of the drilling ship in the Indian Ocean in Phase III of the Project’s operation. The ship sailed from Fremantle, Western Australia, on 1 November 1972 and returned to Fremantle 9 December 1972. The primary objectives of this cruise were to study: (1) The oceanic basement in the far Eastern Indian Ocean, believed by some to be the most ancient in the Indian Ocean. (2) The paleo-oceanic environment of this area. (3) The relationship of the oceanic and continental geologic record in this area.
