Title: Future Plans for Deep Sea Drilling Project: ABSTRACT

Author(s): M. N. A. Peterson

Article Type: Meeting abstract

Abstract:

The Deep Sea Drilling Project, funded by the National Science Foundation, guided by JOIDES, managed by Scripps Institution of Oceanography, and subcontracted for drilling by Global Marine, Inc., of Los Angeles, has been extended for 3 years of drilling. The 7-year period of drilling began August 11, 1968, and will extend until August 11, 1975. The present total estimated cost is approximately $70 million.

Drilling in the past has carried D/V Glomar Challenger into the Atlantic and Pacific Oceans, the Gulf of Mexico, and the Caribbean and Mediterranean Seas. She is presently in the Indian Ocean and will proceed, by present plans, back into the Pacific Ocean in early 1973; in early 1974 her track will go into the Atlantic Ocean, to terminate at the end of contract in the Gulf Coast port. It is hoped that a program of drilling in Antarctic waters can be mounted satisfactorily from the Challenger. Such a program would involve either 2 or 3 austral summers. Additional drilling in the far North Atlantic would be visualized as part of the high-latitude work. It is hoped that penetration into 500-1,000 m of rock beneath the sediment cores can be achieved several times during this period.

Emphasis in the extension program, as assembled by the JOIDES panel structure, includes investigation of (1) chemical history of the oceans, (2) diagenesis, (3) basement rocks, (4) interaction between basement rocks and sediments, (5) history of ocean current systems, (6) organic evolution and productivity, (7) global tectonics, (8) trenches, (9) high-latitude oceans, (10) continental margins, and (11) remanent magnetism.
