Airborne and satellite observations of West Antarctic topography and glacier flow speeds are combined with a computer model simulating ocean-driven glacier melting to show that the ice sheet’s collapse is already underway.

    Arctic 101: UW degree to prep students for a melting world

    The University of Washington is launching a new initiative to boost research in polar regions and prepare students for a world where melting ice is opening new opportunities — and posing new threats. Read the Seattle Times article to learn more about this new program.

    PSC Inviting Applications for Research Scientists

    The Polar Science Center is inviting applications for research scientists with principal investigator responsibilities.  We seek candidates who have completed their post doctoral research with a record that demonstrates high potential to develop their own well-funded program.  Initial research support over a nominal 2-year period will come from start-up funds and existing project funds.

    Sensor-Rich Buoys in the Arctic Ocean

    When doing research in the Arctic the elements are big challenge not just for the humans working there but also for the instruments used to collect data. Ignatius Rigor has set up a testing site outside of Barrow, Alaska to monitor an array of instruments and test their reliability and accuracy. Watch the video to learn more about the project.

    On thin ice: As Arctic Ocean warms, a scramble to understand its weather

    Increasing summer ice melt in the Arctic Ocean could shift global weather patterns and make polar waters more navigable. But scientists say forecasting Arctic ice and weather remains a massive challenge. The prospect of more ice-free water during Arctic Ocean summers has triggered efforts to improve ice and weather forecasts at the top of the world

    Scientists chuck instruments off planes into cracks in Arctic sea ice

    As sea ice disappears in the Arctic Ocean, the U.S. Coast Guard is teaming with scientists to explore this new frontier by deploying scientific equipment through cracks in the ice from airplanes hundreds of feet in the air.

    A New Unified Sea Ice Thickness Climate Data Record

    This new data set is a concerted effort to collect as many observations of sea ice thickness as possible in one place with consistent formats and with clear and abundant documentation. It will allow the community to better utilize what is now a considerable body of observations from moorings, submarines, aircraft, and satellites.

    Arctic Sea Ice Volume Anomaly

    The Arctic Sea Ice Volume Anomaly time series is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) developed at APL/PSC.  Updates will be generated at approximately monthly intervals.
