Deep Sea Drilling Project
THE DEEP SEA DRILLING PROJECT (DSDP; 1968−1983) pioneered scientific ocean
drilling. Begun as a U.S. effort to use ocean drilling to examine the theory of plate
tectonics and development of the ocean basins, DSDP expanded during the
International Phase of Ocean Drilling (IPOD) that began in 1975 to provide important
insights about past climate change, volcanism, and convergent margin tectonics.
Scripps Institution of Oceanography at the University of California, San Diego, ran
science operations using the dynamically positioned drillship Glomar Challenger, and
the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES), a group of four
U.S. universities, later augmented by additional domestic and international members,
provided scientific guidance. During the program, 97,056 meters of core from 624 sites
was retrieved and stored in core repositories, where the cores are still sampled for
scientific research.
