Abstract : The long-term goals are to understand how the marginal ice edge zone (MIZ) interacts with the open ocean in an oceanographic/meteorological/ biological sense. This includes understanding the processes and dynamics for the generation, dissipation and role of mesoscale eddies and chimneys in the MIZ (and in the open ocean after the ice has retreated or melted) in the Greenland Sea/Fram Strait. A further goal is to understand how these physical features interact with the biological and chemical oceanography causing enhancement of biological production in the MIZ and adjacent open ocean. All of this is aimed at understanding the physical and biological controls on the visible and acoustic environment of the MIZ. It is also aimed at understanding the effects of interannual variability and global change which result in variability in flux of carbon, through primary production, to the deep ocean possibly buffering CO2 in the atmosphere.
