The 2019 June 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.
For the 2019 June report, 31 contributions were received that included pan-Arctic predictions, of those contributions six (6) also included pan-Antarctic predictions, and nine (9) included predictions for Alaskan waters. This year, for the first time, there are also seven (7) predictions for the Hudson Bay region.
For the pan-Arctic, the median June Outlook value for September 2019 sea-ice extent is 4.40 million square kilometers with quartiles of 4.2 and 4.8 million square kilometers (The individual outlooks are based on statistical, dynamical models, and heuristic methods. Projected extents are slightly lower compared with 2018 June outlook, but is about the same as in the 2017 June outlook (4.43 million square kilometers). he 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.
