2018 Sea Ice Outlook Post-Season Report Now Available
The 2018 Sea Ice Outlook (SIO) Post-Season Report is now available online. This report centers around forecasts of pan-Arctic September minimum sea ice extent, while also including information about forecasts of sea ice probability and a synthesis of observed Arctic conditions from June to September 2018. It also includes a review of forecasts for the Alaskan sector; an evaluation of the SIO forecast skill; discussions about Antarctic maxima sea ice extent forecasts; the Sea Ice Drift Forecast Experiment; an overview of sea ice forecasting needs of the Alaska marine shipping industry; and ideas of how to continue efforts to understand sea ice predictability and how to create information products that are accessible to stakeholders so that the science can be used in decision making to improve outcomes. The SIO is a community network activity led by the Sea Ice Prediction Network-Phase 2 (SIPN2) Project Team with contributions from key partners.
2018 SIO Post-Season Report - Review Draft Available
The Sea Ice Prediction Network (SIPN2) Project Team invites sea ice experts and members of the SIPN network to provide comments on the preliminary draft of the 2018 Sea Ice Outlook (SIO) full post-season report. This draft report, a product of the SIPN2 Project Team led by Uma Bhatt, includes the main post-season analysis and discussion points. A PDF of the draft report is available online as well as instructions on how to submit comments.
SIPN2 Meeting at AGU Fall Meeting
SIPN2 will convene an open meeting on Tuesday, 11 December from 12:30-1:30 p.m. in Washington, D.C., in conjunction with the AGU Fall Meeting, to promote knowledge exchange and collaboration among members of sea ice research community. A brief overview of the 2018 Arctic sea ice/Sea Ice Outlook season will also be provided. All those interested in Arctic sea ice prediction are welcome to attend!
Sea Ice Outlook Interim Report
The Interim Post-Season Report for 2018 Sea Ice Outlook (SIO) is now available online. The goal of the SIO is to improve sea ice prediction on seasonal time-scales. This interim report is intended as a quick post-season update that summarizes how the outlooks did in comparison to the observed minimum extent. The September monthly averaged sea ice extent was 4.71 million square kilometers, based on the National Snow and Ice Data Center (NSIDC) Sea Ice Index. The median extent of the 39 Outlook contributions for June, July, and August were 4.60, 4.70, and 4.57 million square kilometers, respectively. A full post-season report in January 2019 will include an in-depth analysis of factors impacting sea ice this season; further discussion about the outlooks; comments on regional observations, predicted spatial fields, Antarctic contributions; and a summary from the Sea Ice Drift Forecast Experiment. This report is the product of the Sea Ice Prediction Network–Phase 2 (SIPN2) effort.
2018 Projected Freeze-up of Chukchi Sea Released
The National Oceanic and Atmospheric Administration, Pacific Marine Environmental Laboratory, has released a 2018 projected onset of sea ice freeze-up on the Chukchi Sea continental shelf. Projection: Freeze onset on the Chukchi Sea continental shelf northwest of Icy Cape will begin the second week of December 2018. This is approximately 47 days later than the long-term mean (1981-2016).
