1.1 Large-Scale Dynamic Processes

• changing in Arctic Ocean circulation and water mass exchange via gateways
• changes in large- and medium-scale circulation of Antarctic oceans and atmosphere
• impacts of the Arctic Shelf Seas on water mass conversions and slope convection
• climatic effects of Aerosols and gases on Polar regions and long-term transport patterns
• upper atmospheric processes in solar-terrestrial relations
• Contaminants

1.2 Atmosphere, Oceans and Ice Dynamics and Interactions

• changes in polar Ocean biogeochemistry and productivity
• Air-Sea CO₂ Flux Feedbacks in changing Polar Oceans
• Albedo, Radiation and Atmosphere-Ice-Ocean heat exchange
• deep water formation and renewal and interaction with global overturning circulation
• atmospheric forcing, clouds and composition of Arctic Air Masses

1.3 The Ice and the Oceans

• extent and thickness of Sea-Ice cover and relevant processes
• behavior of the Antarctic Sea-Ice-System and polynias, winter sea ice monitoring
• the role of Polynias for the environmental system of the Arctic Ocean
• stability and dynamics of ice shelves, glaciers and ice caps in the Arctic and Antarctic
