Sea Ice Outlook in the News

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).

June Report for the 2015 Sea Ice Outlook Now Available

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.

Sea Ice Prediction Network Webinar Scheduled

15 April 2015
Sun bounces off of the sea ice on a clear sunny day in the Arctic. Aboard the USCGC Polar Sea icebreaker in the Beaufort Sea.

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.

Sea Ice Concentration Fields for Operational Ice Forecasting

6 April 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.

Sea Ice for Walrus Outlook

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.

SIWO is a collaboration between weather and ice forecasters, climate scientists and sea-ice researchers, and Alaska Native sea-ice experts. 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.
