2. Recover bottom pressure recorders (BPRs) that have been on bottom for over 3 years. The BPR locations are primarily on the ridge axis. They have acoustic transponders and releases that did not work properly when we tried to recover them in 2009. The goal this year is to recover them using the ROV.
3. Collect high resolution bathymetry data along the ridge axis when transiting along the ridge.
