The Sea Ice Prediction Network—Phase 2 (SIPN2) announces the Call for Contributions for the 2019 Sea Ice Outlook (SIO) June report (based on May data).

The Sea Ice Outlook (SIO) 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 Regional Sea Ice Extent Outlooks and any additional figures and gridded fields will be accepted for the 2019 June Outlook. We particularly encourage submissions for the Alaska region (i.e., Bering, Chukchi, and Beaufort seas). For those interested, submissions for Hudson Bay are also accepted. Submissions that include spatial forecast maps are encouraged.

The 2019 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. All participants whose methods provide information at the local scale to are encouraged to provide full spatial fields via the SIPN Data Portal.

Submission process:

See Detailed Guidelines for Contributions, also 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 hosted by the National Snow and Ice Data Center (NSIDC). (Note: You will receive confirmation of your submission via email.)
  • 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 also have the option of submitting information for pan-Antarctic and/or Alaska regional or Hudson Bay sea ice extent projections using the same online web form.
  • Contributors who wish to share supplemental information such as discussion of uncertainties/probabilities, any relevant figures, images, references, or further information about their methods are invited to upload pdf files (less than 20 MB) at the bottom of the same online web form.
  • Submissions of full spatial field sea ice forecasts (full raw fields of sea ice concentration and/or sea ice thickness or post-processed fields) will be collected via the SIPN Data Portal.

Be sure to hit SUBMIT at the bottom of the submission page.
