The 2020 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 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 August report, 39 contributions were received that included pan-Arctic predictions. Of those contributions, 10 included predictions for the Alaska Region and 7 included pan-Antarctic predictions. We received 13 submissions of sea-ice probability and 9 submissions of first ice-free date, and for the August report, ice advance dates were computed from four contributions. For 2020 we also 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 August Outlook value for September 2020 sea-ice extent is 4.30 million square kilometers, with quartiles of 4.1 and 4.5 million square kilometers. The median is close to the observed 2019 September sea-ice extent of 4.32 million square kilometers.

The August 2020 issue of Witness Community Highlights is now available online. This issue includes two articles: “Activity Updates from the Arctic Domain Awareness Center,” an overview of the Center’s mission-driven research efforts and projects; and “Co-Producing Knowledge of Shorefast Ice in Uummannaq Bay, West Greenland,” describing research efforts to combine remote sensing technology with community-based monitoring and local and Indigenous knowledge to better understand how shorefast ice has changed as the Arctic warms and how these changes matter to individuals and communities in the Uummannaq region.

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 Sea Ice Prediction Network–Phase 2 (SIPN2) announces the Call for Contributions for the 2020 Sea Ice Outlook July Report (based on May and June data). The Sea Ice Outlook (SIO) provides an open process for those interested in Arctic sea ice to share ideas. Pan-Arctic and Regional Sea Ice Extent Outlooks and any additional figures and gridded fields will be accepted for the 2020 July Outlook. We particularly encourage submissions for the Alaska region (i.e., Bering, Chukchi, and Beaufort seas). All participants whose methods provide information at the local scale to are encouraged to provide full spatial fields via the SIPN Data Portal. First ice-free dates (IFD) for Hudson Bay will be calculated from the full spatial fields that cover this region. For those interested, submissions the September 2020 80% sea ice concentration contour for Fram Strait are also invited. The 2020 SIO will also accept pan-Antarctic sea ice extent of the September monthly mean. Additionally, we encourage submissions to the associated effort of the Sea Ice Drift Forecast Experiment.

Submission deadline: 6:00 p.m. (AKDT) Monday, 13 July 2020 (Firm).
