Science objectives/activities planned:

ROV dives, deployment and recovery of seafloor instruments, AUV dives, maybe CTD casts and tows

The NeMO seafloor observatory was established in 1997 to conduct time-series measurements of the physical, chemical, and biologic systems at an active submarine volcano. Annual expeditions to Axial Volcano since 1997 have documented important changes following a major eruption in January 1998. Remotely operated vehicles have been used to sample vent fluids, rocks, and biological material, and deploy and recover monitoring instruments on the seafloor. The 2007 program on Atlantis with Jason 2 will continue the time-series measurements and sampling.
A mapping program with the MBARI AUV D. Allan B. was begun in 2006 will continue on NeMO 2007 with the primary goal of finishing a high resolution map of the caldera and the shallow parts of the north and south rift zones.

This cruise will be operated jointly with the NSF-funded program of D. Di Iorio. The first few dives will be at the Endeavour Ridge vent fields to accommodate this program.

Equipment from all investigators will be loaded in Astoria between the July 31 and August 2. The MBARI AUV D. Allan B. will be secured on board. We will depart Astoria for our first site of ROV operations on the Endeavour segment of the Juan de Fuca ridge, working at hydrothermal fields located near 47°57’N, 129°05.7’W and 47°55.1’N, 129°06.75’W, at ~2200meters depth. These sites are within the Canadian EEZ. At the two Endeavour hydrothermal areas, we will deploy and recover instruments and conduct sampling operations as part of an ongoing observatory at the designated Integrated Studies Site. The primary work of Dr. Di Iorio’s group will happen at this site. The MBARI AUV may be deployed at Endeavour if the schedule permits. Following approximately 3 days of work at the Endeavour site, we will transit to the NeMO site at Axial Volcano, at approximately 45º 57.3’ N 130º 00.6’ W. Axial Volcano is located in international waters. Operations at Axial will consist of a combination of instrument recovery and deployment, one long dive of approximately 36 hours for high-precision bottom pressure measurements, other shorter dives with chemical, biological, and geological sampling throughout the caldera, and mapping operations with the MBARI AUV. The MBARI AUV will be deployed and recovered between Jason2 dives, but the number and lengths of the AUV dives will depend on the operational parameters established for the D. Allan B. by summer of 2007 (e.g., whether the ship has to track the vehicle during the dives)After operations at Axial, we hope to also make one or more Jason2 dives to explore previously photographed hydrothermal vent sites on the Cobb Segment.

1.
The primary scientific goals/tasks planned for NeMO 2007 include:

At Endeavour:
1. Recover long-term time-series instruments from one site at Endeavour.
2. Conduct chemical, biological, and geological sampling at Main Endeavour and Mothra hydrothermal fields.
3. AUV mapping in Endeavour Axial Valley (if schedule permits)
4. High-resolution mapping of vent fields at Endeavour.

At Axial:
1. conduct repeat pressure measurements with Jason on seafloor benchmarks, three transects during one ~36 hour dive.
2. Deployment of two seafloor chemical samplers (RAS) on small moorings for un-monitored, pre-programmed time series measurements at Endeavour and Axial.
3. Chemical, biological and microbiological sampling throughout Axial Volcano caldera, CASM, ASHES, and SE (International) vent fields.
4. Recovery of 2 bottom pressure recorders and 4 ocean bottom hydrophones at Axial Volcano and redeployment later during the cruise.
5. Recovery and re-deployment of temperature monitors at seafloor hot spring sites with Jason.
6. CTD/rosette casts at Axial Volcano.
7. Complete high resolution AUV mapping of summit of Axial Volcano
