Arctic Sea Ice Cover in Decline: Impacts on the Interactions in the Atmosphere-Snow-Ice-Ocean Ecosystem II Posters

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.

Session ID#: 13533

Session Description:
The Arctic sea ice cover is transforming from thicker perennial ice to a thinner seasonal ice pack. There is a significant need to understand the ongoing changes in the sea ice cover and its effects on the interaction between atmosphere-snow-ice-ocean and effects on the marine ecosystem, to be able to predict future changes. This session intends to provide an inter-disciplinary forum for researchers working on observations and models to understand the ongoing changes. We solicit submission from recent Arctic studies that include inter-disciplinary aspects involving multiple components of the Artic Ocean system and improves our process-level understanding in the thinner sea ice regime. Such key processes include, changes in ocean heat, stratification and mixing, solar radiation, cloud properties, and effects on primary production. Studies setting recent conditions in context, of e.g. the SHEBA experiment, in modeling studies or utilizing re-analysis data are also welcomed.
