An archive of the Sea Ice Outlook: Post-Season Discussion webinar, held on 9 October 2014, is now available. The webinar, hosted by the Sea Ice Prediction Network (SIPN), focused on post-season analysis and discussion of the 2014 Sea Ice Outlook (SIO) and provided a venue for discussion of the 2014 SIO, including processes that influenced sea ice melt this year and a review of the differing approaches to predicting the sea ice minimum extent.

Announcing the August Sea Ice Outlook report! We received 23 pan-Arctic contributions and four regional contributions. The median Outlook value for September 2014 sea ice extent is 5.0 million square kilometers, with quartiles of 4.58 and 5.22 million square kilometers. This month's report includes comments on modeling outlooks and on regional predictions, a summary of current conditions, key statements from each Outlook, and links to view or download the full outlook contributions.

Sea Ice Outlook

23 July 2014

Announcing the July Sea Ice Outlook report! The Sea Ice Outlook provides a venue for exploring the changing Arctic sea ice extent. It provides a transparent exercise in both scientific sea ice predictions as well as estimates from the public. For the July report, we received 28 pan-Arctic contributions and three regional contributions. The median Outlook value for September 2014 sea ice extent is 4.8 million square kilometers. The report includes a brief executive summary, comments on modeling outlooks and on regional predictions, current conditions, and the individual Outlook contributions.

SIPN Team member Cecilia Bitz announces a call for abstracts for an AGU Session: Processes and Predictability (Session #2392). Presentations that examine the processes that govern seasonal to multidecadal polar climate variability, identify sources of polar climate predictability, and characterize uncertainty in polar climate prediction are welcome. The session seeks to connect the community of atmospheric, oceanic, and cryospheric scientists working on topics relevant to the new Polar Climate Predictability Initiative of the World Climate Research Program. It will convene during the AGU Fall Meetings in San Francisco 15-19 December 2014.

Scientists and educators gather in Barrow, Alaska to learn about Iñupiaq Values Framework from Director of Iñupiaq Education, Jana Harcharek, during Arctic Ocean science curriculum workshop.

ARCUS education staff, with partners, facilitated three workshops for scientists and educations to increase science communication and create educational products. A paper was recently published in the Journal of Geoscience Education to identify the importance of those workshops focusing on culturally responsive curriculum based on alaskan marine ecosystems.
