Sea Ice Prediction Network

The Sea Ice Prediction Network – Phase 2 (SIPN2) invites registration for an open webinar entitled “Machine Learning—Challenges and Opportunities for Applications in Sea-Ice Prediction.” This webinar will focus on the use of Machine Learning and Artificial Intelligence, on how such approaches can be applied in cryospheric research, as well as related challenges and limitations. Discussion will include the use of advanced machine learning algorithms in climate science with attention on how to improve the prediction of future sea-ice. Time for participant questions will follow the presentations. This one-hour event will be held on Wednesday, 29 July 2020 starting at 8:00 am (AKDT).

The 2020 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 predictions and ideas. The monthly reports contain a variety of perspectives—from advanced numerical models to qualitative perspectives from citizen scientists. The Outlook is not an operational forecast.

For the 2020 June report, 33 contributions were received that included pan-Arctic predictions. Of those contributions eight included predictions for pan-Antarctic and the Alaska Region. Additionally, we received 13 submissions of sea-ice probability and ten submissions of first ice-free date. New this year, the report includes ice-free conditions for the Hudson Bay region; September sea-ice concentration contour in the Fram Strait region, motivated by the MOSAiC expedition; and we invited contributors to submit initial conditions (sea-ice concentration and sea-ice thickness) of their forecasts to better understand how observations are being used in forecasts.

For the pan-Arctic, the median June Outlook value for September 2020 sea-ice extent is 4.33 million square kilometers, with quartiles of 4.06 and 4.59 million square kilometers. The median is close to the 2019 June Outlook, of 4.40 million square kilometers, and to the observed 2019 September sea-ice extent of 4.32 million square kilometers.
