The Ocean Drilling Program: After Five Years of Field Operations Conference Paper uri icon

abstract

  • Copyright 1990, Offshore Technology Conference. The Ocean Drilling Program (ODP) has now completed 29 internationally staffed expeditions and five years of scientific ocean drilling. JOIDES Resolution, the scientific drillship of ODP, has travelled in the Atlantic, eastern and northwest Pacific, and Indian oceans, including high latitude zones bordering East and West Antarctica, and the Mediterranean, Caribbean, Weddell, Suiu, Celebes, Philippine and Japan seas, in search of answers to important scientific problems designated by the Joint Oceanographie Institutions for Deep Earth Sampling (JOIDES). These scientific objectives relate to the tectonic evolution of passive and active continental margins, origin and evolution of oceanic crust, origin and evolution of marine sedimentary sequences, and paleoceanography. In addition, ODP has continued modification and reliability of existing coring systems as well as made numerous advances in technology to improve the capture of scientific Information. During its fifth year, the ODP has completed pioneering exploration in the Northwest Pacific Ocean and adjacent seas. Leg 124E, in the Philippine Sea, was our first cruise dedicated to engineering development. Legs 125 and 126 were a two cruise effort designed to study, amongst other important problems, the geological processes involved In the development of the Bonin and Marianas arcs. Legs 127 and 128 were dedicated to study the tectonics and sedimentation history of the Japan Sea. Leg 129 commenced after a dry dock period of JOIDES Resolution, to study the oldest Pacific crust in Pigafetta and east Mariana basins in the Western Pacific. This paper focuses on ODP's scientific successes of five years of scientific ocean drilling and discusses areas of future study.
