The 3-day BEPSII meeting will include a session of the SCOR ECV-Ice working group. We will send out a more detailed agenda for the meeting in a few months (May).

We also invite BEPSII members to submit abstracts to the SCAR Open Science Conference Session 25 “Sea ice in the atmosphere-ice-ocean-biosphere system: How, where and why is it changing, and what are the effects?” (full description below). Please note that the abstract submission for the SCAR Open Science Conference closes on 28 February 2020, 5pm AEST.

Session 25: Sea ice in the atmosphere-ice-ocean-biosphere system: How, where and why is it changing, and what are the effects?
While there is strong focus on rapid change occurring in Arctic sea ice, relatively little is known about the complex sea-ice environment around Antarctica (comprising both pack and fast ice), how and why it is changing and varying, and the wide-ranging physical, biological and chemical effects of such change/variability. Improved understanding of the southern coupled sea ice-ocean atmosphere-biosphere system is required to truly explain the marked and baffling recent reversal in overall sea-ice extent – from a slight positive trend to successive record maxima peaking in 2014, followed by a rapid decline. While sea-ice extent and concentration are monitored reasonably accurately from space, much remains to be learned about the processes driving annual advance and retreat; the role of snow; sea-ice interaction with the ice sheet; sea ice as a habitat; sea ice biogeochemical processes; and teleconnections with lower latitudes (including sea-ice relationships with southern hemisphere weather and climate). A forum for interdisciplinary sea-ice researchers and SCAR’s Expert Group on Biogeochemical Exchange Processes at the Sea-Ice Interfaces (BEPSII) this session invites presentations with a focus on: (i) Antarctic sea ice in the ocean-cryosphere-atmosphere-biosphere system, (ii) sea ice as an active biogeochemical interface and a reservoir for pollutants and (iii) lessons learned from comparing Arctic and Antarctic sea-ice (eco)systems. We encourage a holistic discussion through presentations on sea-ice process, observational, modelling and remote-sensing studies.
