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.
