MAR23 - Sea Ice and Lake Ice in a Changing Arctic - sponsored by Amundsen Science
The Arctic is warming at up to four times the global rate, which is driving a dramatic reduction in Arctic sea ice. As the manifestation of both thermodynamic and dynamic processes across the ocean-sea ice-atmosphere system, sea ice is susceptible to changes in both the atmosphere and ocean that in turn modulate its extent, mobility and thickness. Changes to the ice pack have cascading effects on the entire marine system, such as altering biogeochemical processes, affecting the livelihoods of Inuit, and impacting the maritime industry that operates in Arctic waters. Hence it is critical to understand the processes that act across the ocean-sea ice-atmosphere system and how they modulate ice pack characteristics at all spatial and temporal scales. This broad session covers the oceanographic and atmospheric processes that influence the sea ice cover, and the physical properties of the snow-covered sea ice itself. Studies based on local knowledge, in situ observations, remote sensing and/or modelling are invited.
