Call for abstracts - Session on Changes in the Arctic Ocean, sea ice and subarctic seas systems: Observations, Models and Perspectives at EGU 2019

The EGU General Assembly 2019, taking place in Vienna (Austria) on 7–12 April 2019, will bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences.

We are pleased to invite the communite to submit their abstracts to the session: Changes in the Arctic Ocean, sea ice and subarctic seas systems: Observations, Models and Perspectives.

Details on the session:

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 freshwater influences on the global climate, including the Atlantic meridional overturning circulation 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) that aims to facilitate progress and identify scientific opportunities in (sub)Arctic ocean-sea-ice-atmosphere research.

Please note that the abstract submissions deadline is 10 January 2019, 13:00 CET.

Limited travel support is available, including support for Early Career Scientists:
