U12A:
Fifty Years of Scientific Ocean Drilling: How the Past Informs the Future

Session ID#: 49858

Session Description:
Fifty years ago, the Glomar Challenger sailed the inaugural leg of the Deep Sea Drilling Project (DSDP), coring sediments from the Gulf of Mexico to initiate science-driven, broad-based exploration of the sub-seafloor. Since then, cores, logs and downhole measurements collected under the auspices of DSDP and its successor programs have been the primary means by which researchers have studied long-term Earth system change, providing data of profound scientific and societal importance.

More recently, ocean drilling has explored regions once thought inaccessible, including seismogenic zones, shallow marine environments, and the Arctic and Southern Oceans, while technological advancements have improved core quality, core recovery, and borehole measurements, both wireline and observatory-based. The program currently encompasses four main science themes: climate and ocean change, biosphere frontiers, geodynamics, and geohazards. This session will review achievements in addressing these four priorities of the IODP Science Plan, Illuminating Earth’s Past, Present and Future.
