The Sea Ice Prediction Network (SIPN) announces a call for Sea Ice Outlook (SIO) contributions to the August report (based on May, June, and July data). The SIO provides an open process for those interested in Arctic sea ice to share predictions and ideas about the monthly September minimum sea ice extent. Join a growing network of sea ice experts and contribute a pan-Arctic, regional, or informal Outlook. Submission deadline: Monday, 10 August 2015.

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.

PolarTREC (Teachers and Researchers Exploring and Collaborating) is currently accepting applications. Researchers are invited to submit an application for expeditions during the 2016 (usually Arctic) or 2016-2017 (usually Antarctic) field seasons.

The Sea Ice Prediction Network (SIPN) announces plans to convene a Sea Ice Prediction Workshop tentatively scheduled for 4-6 May 2016 at the Lamont-Doherty Earth Observatory, Columbia University. This workshop will focus on sea ice prediction on sub-seasonal to inter-annual timescales. Organizers welcome participants with interests in research and operational forecasting. 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).

The 2015 Sea Ice Outlook (SIO) - June Report received great media coverage by the Alaska Dispatch News. In an article, posted on 25 June, reporter Yareth Rosen provides a summary of the SIO goals and process, range of methods contributors used, links to Sea Ice Prediction Network (SIPN) and associated agencies, and the June median outlook for sea ice extent in September -- converted to square miles (1.93 million square miles).

We received a record 32 contributions using 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, and predictions fall in a range of 3.3 to 5.7 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.

The Sea Ice Prediction Network (SIPN) will host an open webinar entitled "Observations of Arctic Snow and Sea Ice Thickness from Satellite and Airborne Surveys." The presentation, given by Nathan Kurtz of NASA's Cryospheric Sciences Lab at Goddard, will focus on the current state and availability of snow and sea ice thickness data from NASA's Operation IceBridge airborne surveys and the European Space Agency's CryoSat-2 satellite mission. The accuracy and limitations of these operational data sets will also be discussed to place the utility of the data in context for use in a variety of study areas.

This one-hour webinar is scheduled for 10:00 a.m. AKDT (11:00 a.m. PDT, 12:00 p.m. MDT, 1:00 p.m. CDT, and 2:00 EDT) on Tuesday, 5 May 2015.

NSIDC announces availability of the MASIE-AMSR2 (MASAM2) daily 4 km sea ice concentration, which is a prototype concentration product offering greater accuracy and higher resolution in ice concentration fields used to initialize an operational sea ice forecast model. MASAM2 is a blend of two other daily sea ice data products: ice coverage from the Multisensor Analyzed Sea Ice Extent (MASIE) product, at a 4 km grid cell size, and ice concentrations from the Advanced Microwave Scanning Radiometer 2 (AMSR2) at a 10 km grid cell size. This prototype MASAM2 product currently covers July 2012 through mid-November 2014, but it will become a daily product if there is demand for such a product.

The 2015 Sea Ice for Walrus Outlook (SIWO) is in full swing! Reports will be released each Friday from now until the end of the summer ice season.

It focuses on the ice conditions in the northern Bering and southern Chukchi Seas, and produces weekly reports on ice and weather conditions for Alaska Native subsistence hunters, coastal communities, and anyone interested in sea ice and walrus.
