EGU 2019: Changes in the Arctic Ocean, sea ice and subarctic seas systems

Aksenov, Yevgeny

Dear Colleagues,

  

We kindly remind you that the submission deadline for the EGU-2019 abstracts is the 10 January 2019, 13:00 CET.

 

We invite you to participate in the session OS1.2/AS4.10/CL2.03/CR6.3 “Changes in the Arctic Ocean, sea ice and subarctic seas systems: Observations, Models and Perspectives”.

 

The session is co-sponsored by the Northern Ocean Regional Panel (NORP) of the CLIVAR/CLIC Programme and will be organised at the EGU General Assembly 2019, 7-12 April, Vienna, Austria.

 

Details on the session are below.

 

Please submit the abstracts is via the following link:

We hope to see you in Vienna!

 

With kind regards,

 

Yevgeny, Paul, Craig, Ben and Julienne

Changes in the Arctic Ocean, sea ice and subarctic seas systems: Observations, Models and Perspectives (co-sponsored by NORP) (co-organized) 

Convener: Yevgeny Aksenov; Co-conveners: Paul A. Dodd , Craig Lee , Benjamin Rabe , Julienne Stroeve

 

The past decades of observations have shown sustained changes in the Arctic Ocean and the Arctic sea ice cover. Since the beginning of satellite observations in 1979, the Arctic sea ice extent has declined throughout all seasons, with the largest reduction occurring in summer. Furthermore, the Arctic sea ice cover is now thinner, weaker and drifts faster. The ocean shows an increase in the Arctic freshwater storage and warmer inflows from the Atlantic and Pacific Oceans. Coastal runoff from Siberia and Greenland has also increased. As the global surface temperature rises, the Arctic Ocean is speculated to become seasonally ice-free in the 21st century, which prompts us to revisit our perceptions of the Arctic system as a whole. What could the Arctic look like in the future? How are the present changes in the Arctic going to affect the lower latitudes? What aspects of the changing Arctic should future observations and modelling programs address? The session invites observation- and modelling-based submissions on past, present and future states of the Arctic, on the mutual interaction between ocean, atmosphere and sea ice, and links to global processes. The session addresses Arctic freshwater sources and their effects on regional processes, ocean stratification and ocean acidification. It examines potential Arctic influences on the global climate, including impacts of the Arctic freshwater on the Atlantic meridional overturning circulation, oceanic connections between the Arctic and sub-Arctic seas and greenhouse gases sources from thawing sub-sea permafrost. The session promotes results from current Arctic programs and encourages discussions on future plans for Arctic Ocean modelling and measurement strategies.

 

This session is cosponsored by the CLIVAR /CliC Northern Ocean Regional Panel (NORP). The panel aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.
