Science objectives

Discovery Bay in Jamaica provides a unique opportunity to develop a reconstruction of intense hurricanes that formed in the deep tropics over the course of the last several millennia. With a series of new sediment cores, targeted using Chirp subbottom sonar, we will develop a high-resolution reconstruction of past hurricane-induced event beds. Given documented sedimentation rates in Discovery Bay the temporal resolution will be more than three times greater than existing reconstructions in the Caribbean. With 10-15 m sediment cores we expect to be able to develop a record that extends back to 6000-7000 years before present, and perhaps to as much as 9000 years.

Science Activities

Chirp subbottom sonar survey, multibeam survey, CTD casts, vibracoring (both from Atlantis and from a portable platform at shallow water target), gravity coring, jumbo piston coring, surface sample collection, deployment of current meters.
