The Sea Ice Prediction Network (SIPN) announces the release of the 2015 August Sea Ice Outlook (SIO). There were 38 (including one regional only) contributions—again a new record for the total number of submissions. Contributions were based on a range of methods: statistical, dynamical models, estimates based on trends, and subjective information. The median August Outlook for September 2015 Arctic sea ice extent is 4.8 million square kilometers (km2), 200,000 km2 lower than the June and July medians. This is the last monthly SIO report for the 2015 season. Post-season activities will provide an analysis of the different Outlook methodologist as well as a general review of sea ice dynamics over the summer. For more information, contact Betsy Turner-Bogren (betsy [at] arcus.org).

The Sea Ice Prediction Network (SIPN) announces a call for Sea Ice Outlook (SIO) contributions to the August report (based on May, June, and July data). The SIO provides an open process for those interested in Arctic sea ice to share predictions and ideas about the monthly September minimum sea ice extent. Join a growing network of sea ice experts and contribute a pan-Arctic, regional, or informal Outlook. Submission deadline: Monday, 10 August 2015.

Sea Ice Outlook July Report

23 July 2015

The Sea Ice Prediction Network (SIPN) announces the release of the July Arctic Sea Ice Outlook. We received 35 contributions, surpassing last month’s record number of submissions! The submissions use a range of methods including statistical, numerical models, trend-based estimates, and subjective information. The median Outlook value for September 2015 sea ice extent is 5.0 million square kilometers (km2), which is the same as June’s prediction. The overall range is 3.3 to 5.7 million km2 (with the exception of one 0.98 km2 outlying estimate). This month’s report also includes a discussion about the 11 dynamical model contributions as well as sections on regional predictions and the current conditions of the sea ice.

Sea Ice for Walrus Outlook Released

3 April 2015
Sea Ice for Walrus Outlook

The 2015 Sea Ice for Walrus Outlook (SIWO) is in full swing! Reports will be released each Friday from now until the end of the summer ice season.

SIWO is a collaboration between weather and ice forecasters, climate scientists and sea-ice researchers, and Alaska Native sea-ice experts. It focuses on the ice conditions in the northern Bering and southern Chukchi Seas, and produces weekly reports on ice and weather conditions for Alaska Native subsistence hunters, coastal communities, and anyone interested in sea ice and walrus.
