Polar Seas and the physical processes in the ocean and the atmosphere are
crucial for the ocean thermohaline circulation and climate. Recent years, particularly in the light of approaching the International Polar Year (IPY), have seen increased research effort in high-latitude oceans. Observational programs provide field data and went into the analysis phase. Numerical modelling capabilities have been greatly expanded. The purpose of this session is to present results from observational and modeling activities focusing on the atmosphere-ice-ocean system. We invite researchers working in high-latitude oceans, to discuss their views on ocean processes that are important to ocean and climate variability. We also invite project leaders to report pre-IPY activities and the IPY planning on relevant topics.
Main topics will include (but are not limited to):
- Circulation, water mass formations/modifications and ice cover in high-latitude oceans.
- Horizontal fluxes, interbasin exchanges, variability of the Circumpolar Current, meridional overturning and links to the Global Thermohaline Circulation. Here the focus is on regional studies dealing with interbasin exchanges and the flow through straits and archipelagos. The export products of the high-latitude oceans, such as the overflows across the Greenland Scotland Ridge and the bottom water export in the Weddell Gyre, form important connections to the global conveyor. Process oriented studies are specifically welcome.
- Shelf processes and shelf-basin interactions. Boundary processes strongly influence the properties of the interior oceans. Many aspects of variability make these regions unique. Contributions may include topics like ice melt and growth, polynyas, river discharge, shelf-slope convection, and deep/bottom water formations.
- Small scale processes including air-ice-ocean interactions and vertical fluxes in the ocean. Small-scale processes in high latitude seas are unique feature due to the small Rossby radius. The variable sea ice cover also drives changes on small time and space scales. Topics may include ice edge processes, air-ice-ocean fluxes, mixed layer under sea ice.
