Sea-Level Change

Drilling To Decipher Long-Term Sea-Level Changes And Effects

It has been 15 years since the last planning workshop for reconstructing the history of long-term sea-level changes. Significant progress has been made with ODP drilling on the New Jersey and Australian margins and the Bahamas, with onshore drilling and outcrop studies, and with pending joint IODP-ICDP of the New Jersey inner shelf. The drill still provides an unparalleled means of sampling Cretaceous to Holocene stratigraphic records and calibrating them directly to downhole logs and 3-D geometry afforded by seismic profiles. Recent drilling advances, including the use of mission-specific platforms, together with new views on the roles of tectonics and sediment dynamics, require that the scientific community re-evaluate the fundamental assumptions of sea-level studies.
