Science objectives

This expedition consists of multiple projects lead by different PIs, funded by the NSF, NOAA, and a Chinese University.  All the projects involve Jason dives at either Axial Seamount or Endeavour segment.  The ROV dives will make geophysical measurements of volcano inflation, collect coordinated hydrothermal vent fluid samples for chemical and microbial analysis, and recover and deploy seafloor monitoring instruments in and around hydrothermal vent sites.  Mooring deployments and recoveries between ROV dives at Axial (all moorings short <40 m tall; 3 BPRs, 1 OBH, 1 RAS).

Science Activities

Please see "Science Activities" file, attached as supporting documentation.  Also attached is a tentative shiptrack for the cruise (Astoria -> Axial -> Endeavour -> Astoria), an example of one of the moorings that we will be recovering and deploying, and a file of "known obstables" at Axial Seamount (currently deployed moorings).

Additional Information

Is night time work anticipated on this cruise? yes

Specialized tech support (Seabeam, coring, other):  Multibeam sonar mapping is unlikely, but possible if there is extended downtime with Jason.  "Night time" work is selected only because the Jason operations will probably be around the clock.
