Sea Ice Outlook Interim Report
The Interim Post-Season Report for 2018 Sea Ice Outlook (SIO) is now available online. The goal of the SIO is to improve sea ice prediction on seasonal time-scales. This interim report is intended as a quick post-season update that summarizes how the outlooks did in comparison to the observed minimum extent. The September monthly averaged sea ice extent was 4.71 million square kilometers, based on the National Snow and Ice Data Center (NSIDC) Sea Ice Index. The median extent of the 39 Outlook contributions for June, July, and August were 4.60, 4.70, and 4.57 million square kilometers, respectively. A full post-season report in January 2019 will include an in-depth analysis of factors impacting sea ice this season; further discussion about the outlooks; comments on regional observations, predicted spatial fields, Antarctic contributions; and a summary from the Sea Ice Drift Forecast Experiment. This report is the product of the Sea Ice Prediction Network–Phase 2 (SIPN2) effort.
2018 Projected Freeze-up of Chukchi Sea Released
The National Oceanic and Atmospheric Administration, Pacific Marine Environmental Laboratory, has released a 2018 projected onset of sea ice freeze-up on the Chukchi Sea continental shelf. Projection: Freeze onset on the Chukchi Sea continental shelf northwest of Icy Cape will begin the second week of December 2018. This is approximately 47 days later than the long-term mean (1981-2016).
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 August report. 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, 13 August 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.
