Initial Reports of the Deep Sea Drilling Project - Volume 5

This volume covers Leg 5 of the cruises of the Drilling Vessel Glomar Challenger. Leg 5 of the Deep Sea Drilling Project left San Diego, California, on April 12, 1969, and arrived in Honolulu, Hawaii, on June 5, 1969. During the cruise, twelve sites were drilled to obtain information on the geologic history of the ocean basin. The twelve drilling sites on Leg 5 were located in water depths ranging from 3273 meters to 5405 meters. A total of 869 meters of core were recovered. Of the several overall objectives recommended in the JOIDES Pacific Advisory Panel Report, the Leg 5 drilling program was designed to sample "near fracture zones to investigate the origin of the magnetic anomaly patterns and possible relative movement along the zones," and to recover ". . .continuous sedimentary sections along a longitudinal (N-S) profile for paleontologic and stratigraphic studies."
