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.

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).

The September 2018 issue of Witness Community Highlights is now available online. This issue includes two articles: Highlights of the Arctic Data Center’s recently established Data Highlights page, which provides insights directly from the researchers, including how their data might be applied to other questions in support of Arctic research; and NSF announcements of new Program Directors in the Arctic Sciences Section and new measures to protect the research community from harassment.

PolarTREC (Teachers and Researchers Exploring and Collaborating) is currently accepting applications from researchers for teacher research experiences. Researchers are invited to submit an application to host a PolarTREC teacher in the 2019 Arctic and/or the 2019-2020 Antarctic field seasons. Funding is pending for PolarTREC during the 2019-20 field seasons. ARCUS will keep researcher applicants informed of our funding status. If funding is secured, final matches should be made by January 2019. PolarTREC researchers must be at U.S. institutions. Applications from researchers on National Science Foundation (NSF) funded projects will receive priority in the selection process. Researchers should have secured funding for their research project prior to applying.

As part of the Permafrost Carbon Network's larger effort on 'Reconciling historical and contemporary trends in terrestrial carbon exchange of the northern permafrost-zone', we are initiating a community-effort to develop a comprehensive and annually updated database of high-latitude permafrost zone carbon flux measurements. This database, which builds on a breakout activity from the annual Permafrost Carbon Network meeting in 2017 and previous flux syntheses, could help to track temporal trends in Net Ecosystem Exchange (NEE) and benchmark ecosystem models. We invite you to be a part of this activity.

We seek initial data contributions by September 30th. If you are interested in contributing or have additional questions, please contact marguerite.mauritz [at] nau.edu (Marguerite Mauritz) or ted.schuur [at] nau.edu (Ted Schuur).

Browse SEARCH's Arctic Answers resources, where policy-relevant questions are answered in 1-2 page briefs written by experts, peer-reviewed, and posted in Arctic Answers. Each brief is the top of a "knowledge pyramid" supported by scientific literature organized in underlying tiers of increasing detail. Questions that are addressed include "Can extreme Arctic climate change be avoided with cost effective mitigation?", "How fast is sea level rising?", "How is climate change affecting subsistence (or traditional) fisheries in the high Arctic?" and many more.

SEARCH brought together international experts to estimate how much methane might be released from thawing permafrost in the Arctic. The current state of knowledge and on-going efforts to improve our knowledge are detailed in a project update from EOS magazine. The SEARCH workshop was funded by the National Science Foundation, the National Aeronautics and Space Administration, the U.S. Geological Survey, and the U.S. Arctic Research Commission​.​

The July report for the 2018 Sea Ice Outlook (SIO) is now available online. The goal of the SIO is to improve sea ice prediction on seasonal time-scales. For the July report, 39 contributions were received that include pan-Arctic predictions. Of those contributions, 9 also included pan-Antarctic predictions and 11 included predictions for Alaskan waters. For the Arctic, the median July Outlook value for a September 2018 sea ice extent projection is 4.7 million square kilometers.

The July report includes an overview of projections of total September Arctic ice extent; a section about predicted spatial fields with discussion on sea ice probability (SIP) and the first ice-free day (IFD) from a number of dynamical models; a section on current conditions and atmospheric conditions; a section discussing regional sea ice conditions; and a section discussing Antarctic sea ice extent forecasts.

The July report is the product of the Sea Ice Prediction Network–Phase 2 (SIPN2) effort. The goal of the previous SIPN1 was to enhance scientific discussion on the physics that control summer sea ice extents. In SIPN2 there is a further analysis of quantitatively comparing model forecast output.

PolarTREC has five teachers in the field in July and August. Please join us in following their expeditions. Teachers will be working on Migration and Carry-Over Effects in Arctic Seabirds, Shrubs, Snow and Nitrogen in the Arctic, Permafrost and Community, Sliding Glaciers and Winter Respiration in the Arctic. Also, please join us for upcoming PolarConnect Events with each of these teachers.

The June 2018 issue of Witness Community Highlights is now available online. This issue highlights results from a recent program that focused on the sea state and boundary layer physics of the emerging Arctic, defined by less sea ice and larger expanses of open water in summer. The program was motivated by the observed increase in surface wave activity that has been coincident with the seasonal reduction in sea ice.

The June report for the 2018 Sea Ice Outlook (SIO) is now available online. The goal of the SIO is to improve Arctic sea ice prediction on seasonal time-scales. For June, we received 34 contributions that include pan-Arctic predictions, of those contributions 10 also included pan-Antarctic predictions and 11 included predictions for Alaskan waters. We received one additional contribution with a regional focus on the Nares Strait. For the Arctic, the median June Outlook value for a September 2018 sea ice extent projection is 4.6 million square kilometers. The June report includes analysis of the contributions, predicted spatial fields with discussion on sea ice probability (SIP) and the first ice-free day (IFD) from a number of dynamical models; a section on current conditions with discussion on this winter's record low sea ice conditions and atmospheric conditions; a section discussion regional ice conditions; and a section discussing Antarctic sea ice extent forecasts.
