The overarching aims of this workshop are to:

  • Summarize the existing knowledge of changes for a number of selected physical and biogeochemical variables and parameters, representative of the sea-ice ecosystem
  • Make a first tentative analysis of the effects of the predicted changes in the sea-ice horizon on the Arctic ecosystem.
  • To generate an accessible description of future changes in sea-ice biogeochemistry to focus scientific efforts, raise public awareness and facilitate climate policy making.

The workshop will aim to select appropriate variables and parameters, and provide evidence-based estimates of their changes within a pre-defined bandwidth of uncetainties. A two-step approach will be applied, which will involve quantifying the current status of the selected parameters/variables based on existing reviews and literature studies, before estimating changes for the selected paramters/variables over the coming decades, based on literature and modelling exercises.

Expected outcomes

  1. A scientific position paper on expected changes in ecology and biogeochemistry of the Arctic sea-ice environment related to changes in sea-ice physics.
  2. A comprehensible visualization diagram that illustrates expected changes in the Arctic sea-ice environment to serve policy makers and raise public awareness

Whereas the position paper and the diagram will have different audiences (scientists vs. the general public and policy makers), both will serve a similar goal. The summary exercise proposed here will clarify how climate change in the Arctic will impact the sea-ice biome, increasing our awareness of the specific sensitivity of Arctic sea-ice ecosystems and their exchanges with surrounding environments. For scientists, the position paper will serve as a guideline to focus future scientific efforts. At the same time, the diagram will allow scientists to better communicate climate change impacts to the general public.

Policymakers may use the synthesis to better define sustainable management of Arctic sea-ice related systems. An up-to date diagram may serve as a tool to illustrate not only the sensitivity of several individual parameters but also assess the resilience of the Arctic system as a whole.


In order to maximize resources, this workshop was organized as one of the side meetings preceding the IASC/SCAR POLAR2018 open-science conference in Davos, Switzerland.The workshop was organized in conjunction with the annual meeting of the BEPSII (Biogeochemical Exchange Processes at Sea-Ice Interfaces) science community.In total, 40 people representing 14 countries attended the ASIC workshop and BEPSII meeting.The ASIC workshop covered the full first two days. 


An opinion paper was planned for submission in early summer 2019 as an invited perspective paper in Nature Climate Change. This paper will aim to deliver opinion tables in which the responses of BGC processes to the two scenarios in the different provinces covered in the workshop are predicted, and in which at the same time the level of certainty of the prediction is provided.
