The deep sea drilling project, funded under the National Science Foundation Research Program For Oceanic Sediment Coring, completed its first year of operations on Aug. 12. The project, along with other scientific objectives, is aimed at providing new knowledge of the oceans, their history, and record of changing climate and evolving life. Drilling and coring are being done with Global Marine's Glomar Challenger, a dynamically positioned drill ship of the Glomar Grand Isle class. This ship has been modified for deep-sea coring by the addition of such items as core labs for core description, satellite navigation for precise positioning, automatic picture transmission for weather forecasting, an oceanographic winch and ''A'' frame for piston coring, precision profiling equipment, and air gun and magnetometer. Drilling and propulsion power is supplied by twelve 1,000 hp diesels driving eleven 500 kw D-C generators and three 500 kw A-C generators. Two diesels selectively drive either an A-C or a D-C generator. The D-C generators are selectively assigned to propulsion or drilling equipment. All ship systems are giving reliable performance.
