Overview

Sea Ice for Walrus Outlook

The Sea Ice for Walrus Outlook (SIWO) is a resource for Alaska Native subsistence hunters, coastal communities, and others interested in sea ice and walrus. The SIWO provides weekly reports from April through June with information on weather and sea ice conditions relevant to walrus in the northern Bering Sea and southern Chukchi Sea regions of Alaska.

The Outlooks are produced with information on weather and sea ice conditions provided by the National Weather Service - Alaska Region and Alaska Native sea ice experts. SIWO partners include the Eskimo Walrus Commission, the Arctic Research Consortium of the U.S. (ARCUS), and scientists at the National Weather Service and the University of Alaska Fairbanks. Funding for SIWO is provided to ARCUS by the National Science Foundation's Division of Arctic Sciences (PLR-1304316). SIWO is considered a contribution to the Study of Environmental Arctic Change (SEARCH).

Current Outlook Observations

  • Observations from Wales

    1 June 2018 – Robert Tokeinna, Jr.

    This week our Village Creek has fully opened up, but not quite ice or snow free. Hunters were catching both types of seals and walrus has been caught also. For pictures, the sea ice hung around for a day or two then drifted out at the beginning of the week then is ice free for now. There is sufficient amount of snow around town still, but it has warmed up nicely to also melt couple inches from last week. Overflows and running of creeks and runoffs are noticeable throughout the area. Snipes and different types of swallows were noticed around town along with snow geese, cranes, and other sea bearing ducks have been flying or hanging around. Temperatures were lower to mid 20's then warming up to 30 plus degrees at the end of the week. This ends my report.
