ARCUS invites registration for our next Arctic Research Seminar featuring Anna Liljedahl (University of Alaska Fairbanks). This seminar, titled “Permafrost Hydrology Discoveries and Opportunities”, will be held Friday, 1 November 2019 from 10:00-11:00 a.m. AKDT (2:00-3:00 p.m. EDT) online via Zoom.

A new publication in Nature Climate Change provides a baseline for winter CO2 emissions from northern terrestrial regions and indicates that enhanced soil CO2 loss due to winter warming may offset growing season carbon uptake under future climatic conditions. This science synthesis effort was led by Dr. Susan Natali and the Permafrost Carbon Network.

The October 2019 issue of Witness Community Highlights is now available online. This issue includes an article “Widespread Permafrost Degradation in the Canadian High Arctic at 80°N,” summarizing results from a recent study that suggest complex causes to the rapid increases in signs of permafrost instability in the polar desert of the high Arctic.

The 2019 Sea Ice Outlook Interim Post-Season Report is now available. The September monthly averaged sea ice extent at the end of the 2019 summer melt season was 4.32 million square kilometers. This is the third lowest in the satellite record that began in 1979.

This interim report is intended as a quick postseason update that summarizes how the outlooks did in comparison to the observed September monthly mean extent. A full post-season report, to be published in February 2020, will include an in-depth analysis of factors impacting sea ice this past summer, further discussion about the outlooks, comments on regional observation, predicted spatial fields, Antarctic contributions, and a summary from the Sea Ice Drift Forecast Experiment (SIDFEx).

The 2019 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 ideas. The monthly reports contain a variety of perspectives—from advanced numerical models to qualitative perspectives from citizen scientists. The Sea Ice Outlook provides an open process for those interested in Arctic sea ice to share predictions and ideas; the Outlook is not an operational forecast.

A record number of 42 Pan-Arctic outlook contributions were received for the August report. Of those contributions 7 also included pan-Antarctic predictions, 11 included regional predictions for Alaskan waters, and 5 were for the Hudson Bay region.

For the August report the pan-Arctic median value for September 2019 sea-ice extent is 4.22 million square kilometers and with quartile values of 4.0 and 4.4 million square kilometers.Although pan-Arctic sea-ice extent was tracking very close to the record minimum of 2012 from mid-June through mid-August, the rate of melt slowed down in late August. A record minimum extent is not expected for 2019, unless late summer storm activity consolidates ice extent.

The Sea Ice Prediction Network – Phase 2 (SIPN2) invites registration for an open webinar entitled "An Overview of European Union-Funded Project APPLICATE" featuring Pablo Ortega, Earth Science Department, Barcelona Supercomputing Center. This webinar will provide an overview on the EU-Funded H2020 project APPLICATE, whose main goal is to advance our capability to predict the weather and climate in the Arctic and beyond. It will present a few examples on the seasonal prediction activities carried out within the project. These include an analysis on how the different forecast errors are developed in the EC-Earth system, a multi-model comparison of predictive skill in all the seasonal forecast systems participating to the Consortium, results from empirical statistical models used for benchmarking, and experiments exploring the added-value of increasing both the atmospheric and oceanic resolution on seasonal prediction. This event will be held on Tuesday, 17 September 2019 from 8:00 a.m. to 9:00 a.m. AKDT.

The July 2019 issue of Witness Community Highlights is now available online. This issue includes two articles: “Working for Food Security in Interior Alaska,” which summarizes a case study of how stake-holders in northern cities ensure a high level of food security; and “Tracking Ticks in Alaska: Understanding how an Invasive Species may Impact the Health of Humans and Animals in the Arctic” discusses recent work to understand if invasive ticks are being imported, and surviving, in the Arctic.

The Sea Ice Prediction Network–Phase 2 (SIPN2) announces the call for contributions for the 2019 Sea Ice Outlook August report (based on May, June, and July 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 2019 August Outlook. We particularly encourage submissions for the Alaska region (i.e., Bering, Chukchi, and Beaufort seas). For those interested, submissions for Hudson Bay are also accepted. Submissions that include spatial forecast maps are encouraged.

The 2019 SIO will also accept pan-Antarctic sea ice extent of the September monthly mean. Informal sea ice observations and other parameters not included in the regular monthly reports are also invited. All participants whose methods provide information at the local scale to are encouraged to provide full spatial fields via the SIPN Data Portal.
