Sea Ice Action Team Co-Chair, Jennifer Francis, will be the plenary speaker for the Implications of a Changing Arctic on Water Resources and Agriculture in the Central U.S. workshop taking place at the University of Nebraska-Lincoln's School of Natural Resources on November 10, 2015 from 7-9pm.

The goal of the workshop is to build public awareness on the importance of the Arctic and the implications of changes in this region for the central U.S. The workshop is sponsored by NOAA's National Integrated Drought Information System, USDA's Office of the Chief Economist and the University of Nebraska-Lincoln's School of Natural Resources.

The Science Steering Committee (SSC) of the Study of Environmental Arctic Change (SEARCH) program has announced the selection of Brendan Kelly, PhD as its new Executive Director. Dr. Kelly will assume the duties of his new role on 21 September 2015.

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).

Registration and abstract submission is now open for the Arctic Observing Open Science Meeting. The meeting will be held 17-19 November 2015 in Seattle, Washington. The open meeting will provide an opportunity to present and discuss scientific findings and advances resulting from Arctic observing projects funded by federal, state, and local agencies, and private and non-profit organizations.

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.

Forecast users are especially encouraged to attend. Outcomes of the meeting will include recommendations for the Sea Ice Outlook and other activities related to sea ice prediction. More specific meeting goals will be available closer to the event. To stay informed about this meeting, please subscribe to the SIPN mailing list. For questions, contact Betsy Turner-Bogren (betsy [at] arcus.org).

SEARCH and the Polar Research Board announce a call for abstract submissions to a general session of the American Geophysical Union (AGU) 2015 Fall Meeting on the effects of system-wide Arctic change (Session #8477). The meeting will be held in San Francisco 14-18 December. The abstract submission deadline is 5 August 2015. For more information, contact Sea Ice Action Team co-lead Jennifer Francis (francis [at] imcs.rutgers.edu).

Registration is now available for a SIPN webinar entitled "Industry Needs for Seasonal and Sub-seasonal Sea Ice Information and Predictions." This webinar will provide a brief overview of contrasts and commonalities between sea ice variables relevant for geophysical or climate research and those relevant for operational needs in Arctic seas. It is scheduled for Tuesday, 11 August 2015 from 9:00 a.m. to 10:00 a.m. AKDT. For more information, contact Betsy Turner-Bogren at ARCUS (betsy [at] arcus.org).

Igor Polyakov et al. seek public comment on a white paper summarizing the concept of an experimental program drafted by participants of an open workshop entitled "Observations of upper-ocean and sea-ice interactions in the eastern Arctic Ocean," which convened 24-25 April 2014. More information about the workshop is available here. The deadline for public comments is Friday, 24 July. Comments and questions should be directed to Igor Polyakov (igor [at] iarc.uaf.edu).
