Description
Leg I focused on biological objectives in Norfolk Canyon, with some sampling in Baltimore Canyon. Leg II focused on archaeological targets in and around the Norfolk Canyon area, with some emphasis on biological objectives to expand upon data collected during last years cruise. 24-hour operations included 12-16 hour remotely operated vehicle (ROV) dives which took digital images and high definition video of the seafloor and collect water, sediment, and different types of fauna for research objectives during the day. Night operations included non-ROV sampling, including box coring, bottom trawling, recovery of benthic landers, multibeam mapping, collection of water column environmental data, and water sampling (using a CTD instrument with niskin bottle rosette). Data expected: Scientific Computing System (SCS) data, ROV sensor data, Underwater video/framegrab images, sampling logs/analyses, CTD data, summary reports
