Deep Sea Explorer. This is a port side view of the Deep Sea Drilling Project drilling vessel, Glomar Challenger, which is drilling and coring for ocean sediment in all the oceans of the world. Scrips Institution of Oceanography, of the University of california at San Diego, is managing institution for DSDP under a $34.8 million contract with the National Science Foundation. The drilling vessel is owned and operated by Global Marine, Inc., of Los Angeles, which holds a subcontract with Scripps to do actual drilling and coring work. The Glomar Challenger weighs 10,400 tons, is 400 feet long and the million-pound hook-load capacity drilling derrick stands 194 feet above the water line. She is the first of a new generation of heavy drilling ships capable of conducting drilling oerations in open ocean, using dynamic positioning to maintain position over the bore-hole. A re-entry capability was established on June 14, 1970, which will enable the changing of drill bits and re-entering the same bore-hole in the deep ocean. Forward is the automatic pipe racker, designed by Global Marine Inc., which holds 24,000 feet of 5-inch drill pipe.
