The New Jersey margin scientific drillig project (IODP Expedition 313): Unstangling the record of global and local sea-level changes

Abstract : Much of the world is currently experiencing shoreline retreat due to global sea level rising at the rate of 3–4 mm yr -1. This rate will likely increase and result in a net rise to roughly 1 m above present sea-level by the year 2100 (e.g., Rahmstorf, 2007; Solomon et al., 2007), with significant consequences for coastal populations, infrastructures, and ecosystems. Preparing for this future scenario calls for careful study of past changes in sea level and a solid understanding of processes that govern the shoreline response to these changes. One of the best ways to assemble this knowledge is to examine the geologic records of previous global sea-level changes. Integrated Ocean Drilling Program (IODP) Expedition 313 set out to do this by recovering a record of global and local sea-level change in sediments deposited along the coast of eastern North America during the Icehouse world of the past 35 m.y. What we learn from this record—the factors driving sea-level changes, and the impact of this change on nearshore environments—will help us understand what lies ahead in a warming world.
