HE24C:
North Atlantic-Nordic Seas-Arctic Ocean Heat Exchanges: Processes and Impacts II Posters


Session ID#: 29748

Session Description:
Exchange flows between the subpolar North Atlantic and the Arctic Ocean via the Nordic Seas are key components of the global climate system. The southward deep overflows feed the abyssal limb of the Atlantic Meridional Overturning Circulation affecting global climate, and the northward heat transport by the Atlantic Water affects Arctic sea ice and land ice cover, ecosystems, European weather and global climate. While knowledge of the magnitude of these fluxes and of their driving mechanisms are key to predicting changes on both the Atlantic and the Arctic sides, the processes and timescales involved are poorly understood.

This session invites contributions that address any of the exchange flows, their driving mechanisms, and downstream impacts of changes on either the Atlantic or the Arctic side. It aims to bring together observational, theoretical and numerical work on issues including but not limited to dynamics and kinematics of the regional ocean circulation, local and remote impacts of changes in oceanic heat transports on the atmosphere, sea ice, marine terminating glaciers, and biogeochemistry, and their linkages and predictability.
