The 2019 August Sea Ice Outlook (SIO) report is now available online. The Sea Ice Outlook, an effort managed by the Sea Ice Prediction Network–Phase 2 (SIPN2), 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. The Sea Ice Outlook provides an open process for those interested in Arctic sea ice to share predictions and ideas; the Outlook is not an operational forecast.
A record number of 42 Pan-Arctic outlook contributions were received for the August report. Of those contributions 7 also included pan-Antarctic predictions, 11 included regional predictions for Alaskan waters, and 5 were for the Hudson Bay region.
For the August report the pan-Arctic median value for September 2019 sea-ice extent is 4.22 million square kilometers and with quartile values of 4.0 and 4.4 million square kilometers.Although pan-Arctic sea-ice extent was tracking very close to the record minimum of 2012 from mid-June through mid-August, the rate of melt slowed down in late August. A record minimum extent is not expected for 2019, unless late summer storm activity consolidates ice extent.
