“…DSDP was inherently exploratory and global-ranging, and in that mode made many key scientific contributions-see the section below on Selected Achievements of Scientific Ocean Drilling . DSDP also made important technological contributions, including development of deepwater reentry capabilities (1970) and the hydraulic piston corer (1979) for soft to semi-lithified sediments that continues to be the workhorse of the science of paleoceanography (see Moore and Backman, 2019, in this issue). In 1983, DSDP was formally concluded, and Texas A&M University was named as the science operator for the Ocean Drilling Program (ODP).…”
