2018 June Sea Ice Outlook Report Available
The June report for the 2018 Sea Ice Outlook (SIO) is now available online. The goal of the SIO is to improve Arctic sea ice prediction on seasonal time-scales. For June, we received 34 contributions that include pan-Arctic predictions, of those contributions 10 also included pan-Antarctic predictions and 11 included predictions for Alaskan waters. We received one additional contribution with a regional focus on the Nares Strait. For the Arctic, the median June Outlook value for a September 2018 sea ice extent projection is 4.6 million square kilometers. The June report includes analysis of the contributions, predicted spatial fields with discussion on sea ice probability (SIP) and the first ice-free day (IFD) from a number of dynamical models; a section on current conditions with discussion on this winter's record low sea ice conditions and atmospheric conditions; a section discussion regional ice conditions; and a section discussing Antarctic sea ice extent forecasts.
Call for Sea Ice Outlook Contributions
The Sea Ice Prediction Network–Phase 2 (SIPN2) announces the call for contributions for the 2018 Sea Ice Outlook June report (based on May data). 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. Submissions are due Monday, 11 June 2018.
Phase 2 of the Sea Ice Prediction Network (SIPN2)
The Sea Ice Prediction Network is now funded through a new collaborative proposal, "Advancing Predictability of Sea Ice: Phase 2 of the Sea Ice Prediction Network (SIPN2)". SIPN2 will result in a better quantification of the role of oceanic heat and climate variations in the Pacific sector of the Arctic; new observational-based sea-ice products; and activities to improve seasonal predictability of Arctic sea ice, the limits of this predictability, and the economic value of forecasts for stakeholders.
Arctic Sea Ice Prediction Stakeholders Workshop
An "Arctic Sea Ice Prediction Stakeholders Workshop" will be held on Monday, 22 January 2018 in conjunction with the Arctic Frontiers Conference in Tromso, Norway. This workshop will bring together sea ice stakeholders and forecasters to:
1) Assess the value of forecasts by the user community.
2) Determine if and how ice forecasts are currently being used in decision making.
3) Communicate the relevant metrics needed by various stakeholders.
4) Identify where improvements in sea ice forecasts would help stakeholders make decisions.
5) Communicate the limits and opportunities of current forecasting systems.
2017 Projected Onset of Sea Ice Freeze-up on the Chukchi Sea, NOAA PMEL
The National Oceanic and Atmospheric Administration, Pacific Marine Environmental Laboratory, released a 2017 Projected onset of sea ice freeze-up on the Chukchi Sea continental shelf northwest of Icy Cape will begin near the end of November to the first week of December. This is approximately 36 days later than the long-term mean (1981-2016). The metric is defined by sea-ice concentration reaching 30% as determined by passive microwave observation.
