Detailed guidelines for contributors can be found at:

The Sea Ice Outlook provides an open process for those interested in Arctic sea ice to share ideas. The monthly reports contain a variety of perspectives—from advanced numerical models to qualitative perspectives from citizen scientists. Post-Season Reports will provide analysis and discussion of factors driving sea ice extent and explore the scientific methods for predicting seasonal conditions.

Pan-Arctic and Alaska Regional Sea Ice Extent Outlooks and any additional figures and gridded fields will be accepted for the 2018 June Outlook. We particularly encourage submissions for the Alaska region (i.e., Bering, Chukchi, and Beaufort seas) and submissions that include spatial forecast maps. The 2018 SIO will also accept pan-Antarctic sea ice extent of the September monthly mean. Informal sea ice observations and other parameters not included in the regular monthly reports are also invited.

New this year: all participants whose methods provide information at the local scale are encouraged to provide full spatial fields via the new SIPN Data Portal ( We can compute metrics such as sea ice probability and first ice-free day for you, as well as additional regional analysis for the Sea Ice Outlook.

Submission Process:

Detailed contributor guidelines are available at:, and are summarized below.

  • Required core information for Pan-Arctic Outlook projections using dynamical model, statistical, heuristic, and mixed methods will be collected via an online web form:
  • Contributors have the option of submitting additional Outlook report details, including discussions and details related to uncertainties/probabilities, via the same online web form:
  • Contributors who want to share supplemental information such as figures, images, references, or further information about their methods are invited to submit via Dropbox. Please email Betsy Turner-Bogren (This email address is being protected from spambots. You need JavaScript enabled to view it.) for the link to Dropbox.
  • Submissions of spatial field sea ice forecasts (full raw fields or post-processed fields) will be collected via a new SIPN Data Portal. Please see further instructions below.
  • Note: If either the online onweb form or Dropbox are not workable options, files may be sent via email to: This email address is being protected from spambots. You need JavaScript enabled to view it..

Associated Effort:

Contributions are also invited to the Sea Ice Drift Forecast Experiment (SIDFEx, 2017-2020) - a community effort to collect and analyze Arctic sea ice drift forecasts at lead times from days to a year based on arbitrary methods for a number of sea-ice buoys and, ultimately, the MOSAiC Drift. SIDFEx is aligned with the SIO such that modelling groups contributing to the Sea Ice Outlook can contribute to SIDFEx relatively easily by computing trajectories for Lagrangian tracers. Last year’s results have been described briefly in the 2017 post-season report. For details, please go to:
