Depart Bridgetown, Barbados on Voyage #210-05. Upon completion of science activities, the vessel shall call upon the port of Woods Hole, MA on or about 19 June 2013. The science objectives of this cruise will include understanding the processes controlling the formation, evolution and linking of mid-segment detachment faults, and to examine the relationship between magma supply along the ridge axis and detachment fault formation. The scientific plan will be to obtain regional multibeam bathymetry and magnetic data to understand the spreading history out to 5 Ma. High-resolution multibeam bathymetry, magnetic, CTD and optical sensor data will be collected from the autonomous underwater vehicle (AUV) Sentry, and photographs from the WHOI TowCam. There will also be an extensive dredging operation.
Image Of the Day caption:
During a June 2013 trip from Barbados to Woods Hole, scientists and engineers on board R/V Knorr took a close look at regions of the seafloor along the Mid-Atlantic Ridge that present a new form of sea floor spreading. In it, instead of seafloor simply spreading appart, the lower crust and mantle are uplifted and spread away from the ridge axis onto one oceanic plate, while the shallow crust and seafloor lavas spread in the opposite direction through a process known as detachment faulting. The team collected high-resolution images of the seafloor, dredged up rock samples, and carried out photographic, geophysical, and hydrographic surveys using the autonomous underwater vehicle Sentry (pictured) and TowCam. Together, the data collected will help improve scientists' understanding of how the seafloor has formed and changed over the past 5 million years.
