| Summary | 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. | ||||||||

| Biotic observations derived from underwater video | Remotely Operated Vehicle | Physical, environmental, and biotic observations were derived from underwater video collected by the Monterey Bay Aquarium Research Institute (MBARI) using remotely operated vehicles (ROVs) offshore of Morro Bay, California. The data were acquired during three separate surveys in 2019 in support of the U.S. Geological Survey (USGS)/Bureau of Ocean Energy Management (BOEM) California Deepwater Investigations and Groundtruthing I (Cal DIG I) project. | Guy R Cochrane |
| Substrate observations derived from underwater video | Remotely Operated Vehicle | Physical, environmental, and substrate observations were derived from underwater video collected by the Monterey Bay Aquarium Research Institute (MBARI) using remotely operated vehicles (ROVs) offshore of Morro Bay, California. A majority of the data were acquired during three separate surveys in 2019 in support of the U.S. Geological Survey (USGS)/Bureau of Ocean Energy Management (BOEM) California Deepwater Investigations and Groundtruthing I (Cal DIG I) project. | Guy R Cochrane |
