The European Geosciences Union General Assembly 2018 conference will convene 8-13 April 2018 in Vienna, Austria.

Organizer of the following session invite abstract submissions:

SESSION OS1.7/CR6.2: Changes in the Arctic Ocean Sea Ice and Subarctic Seas Systems: Observations, Models and Perspectives
Conveners: Yevgeny Aksenov, Agnieszka Beszczynska-Moller, Craig Lee, Benjamin Rabe, Markus Janout, Julienne Stroeve, Paul A. Dodd.

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 revisit of 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 modeling programs address?

The session invites observation- and modeling-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. This session examines potential Arctic freshwater influences on the global climate, including the Atlantic meridional overturning circulation and greenhouse gases sources from thawing sub-sea permafrost and promotes results from current Arctic programs and encourages discussions on future plans for Arctic Ocean modeling and measurement strategies
