Summary of Activity and Data Gathered: Piston and Gravity Coring. Coring was conducted for the most part during daylight hours at the request of the Ship’s Captain. The piston coring rail system was arranged on the fantail at a slight diagonal to allow a line and capstan to be rigged on the starboard deck to pull the corer along rails. Cores were collected on 12 of the 13 days at sea. A total of 41 cores were collected. The ROV dives were impacted more significantly by weather conditions that the coring operations. Objectives had to be achieved by modifying the original site plan. Of the original plan ten of the original sites were surveyed three of which were considered priority 1 sites out of 23 total dives. Video data are archived with MBARI.
Staff: Maureen Walton, Daniel Powers, Peter Dal Ferro
Notes: Numerous MBARI staff for coring and ROV.
