Survey Cruise Objectives

Purpose of the survey work is 1) to map the distribution and abundance of krill, their prey field, and predators, 2) to map the hydrography and current structure in the survey area to provide a context for interpreting the biological distributions and their coupling to the environment, and 3) to conduct coordinated smaller scale studies with the process group of krill and their physical/biological environment. Although Marguerite Bay is central to the broad-scale survey work, the cruise track will be determined in part by the presence/absence of ice and adjustments may have to be made to extend the survey further south during the fall cruise to reach an ice-edge region. 

On Station Activities during a survey. 

Primary Work:

	CTD profile to bottom
	XBT
	Turbulence Profile
	MOCNESS tow (~16 stations)
	ROV profile (@ MOCNESS stations)
	SONA buoy deployment (when last out of range)
	Deploy Drifters when in ice free region
	Ice core when in ice.
	Penguin stomach contents when in ice and penguins present.

Other work:
	Repeat work at some stations on grid.
	Coordinated ship work - fine-scale surveys
	Krill/MOCNESS/Lighting avoidance study.
	ROV light quality experiment
	Shelf water intrusion Experiment
	Run Shipboard models - Data assimilation - produce nowcast.

Total bunks needed - max (min)	37 (32)

Note: The reduction in 3 bunks indicated for Ashjian et al., can occur if a marine tech is present in the BIOMAPER II van to assist in "flying" BIOMAPER II on each watch.
