-- News Polar bears are getting thinner and having fewer cubs. Melting sea ice is to blame February 14, 2020 – The impact of the climate crisis is becoming more and more obvious to humans and their animal neighbors. But among all species, polar bears might be some of the hardest hit. read more » Polar bears in Baffin Bay skinnier, having fewer cubs due to less sea ice February 12, 2020 – Polar bears are spending more time on land than they did in the 1990s due to reduced sea ice, new University of Washington-led research shows. Bears in Baffin Bay are getting thinner and adult females are having fewer cubs than when sea ice was more available. read more » Polar Bears Struggle as Sea Ice Declines February 4, 2020 – A polar bear’s life seems simple enough: eat seals, mate, and raise cubs. But a recent study shows some subpopulations of polar bears are struggling to complete these essential tasks because of declining concentrations of Arctic sea ice. read more » Last Arctic ice refuge is disappearing November 12, 2019 – Former UW Arctic Fulbright Chair, Kent Moore with PSC researchers Axel Schweiger, Jinlun Zhang and Mike Steele on how the oldest and thickest Arctic sea ice is disappearing twice as fast as ice in the rest of the Arctic Ocean. read more » Two UW ice researchers to participate in year-long drift across Arctic Ocean September 20, 2019 – PSC’s Bonnie Light and Madison Smith will participate in the MOSAiC expedition in 2020. Read the UW News story to learn about the expedition and how it will contribute to Arctic research. read more » Century-Old Ship Logs Show How Much Ice the Arctic Has Lost September 17, 2019 – Research by Axel Schweiger and Jinlun Zhang in Collaboration with Kevin Wood from JISAO reconstructs sea ice volume and thickness since 1901. read more » Shipping logs show how quickly Arctic sea ice is melting August 13, 2019 – The Economist covers research by Axel Schweiger and Jinlun Zhang in collaboration with Kevin Wood at JISAO. Reconstruction of sea ice thickness and volume since 1901 uses logs from old US revenue cutters traveling in the Arctic in the early 20th century. read more » Hacking ICESat-2: How an Open Science Workshop Helped Scientists Wrangle Big Data August 2019 – NASA’s Center for Climate Simulation reported on the recent Cryospheric Science Hackweek held at UW. The article includes an interview with PSC’s Anthony Arendt and workshop coverage from other planners, facilitators, and participants. read more » ICESat-2 Hackweek 2019 June 18, 2019 – This week is ICESat-2 Hackweek 2019 , held at the University of Washington. Participants are learning about technologies used to access and process ICESat-2 data with a focus on the cryosphere. read more » Researchers test ice probe on Mount Baker June 15, 2019 – PSC’s Dale Winebrenner and his team conducted fieldwork on Mount Baker’s Easton Glacier with the help of a local snowmobile club. The team is involved in developing equipment to better study lakes beneath not only the Antarctic ice but hopefully under the ice on other planets. read more » Low‐Level and Surface Wind Jets Near Sea Ice Edge in the Beaufort Sea in Late Autumn June 6, 2019 – The latest paper authored by Zheng Liu and Axel Schweiger has been published in JGR Atmospheres . Read how dropsonde observations made from Seasonal Ice Zone Reconnaissance Survey flights were used to examine low‐level and surface “ice edge jets” in the Beaufort Sea. read more » Al Roker travels to the Arctic for firsthand look at climate change April 1, 2019 – TODAY Show host, Al Roker, traveled to Utqiagvik, Alaska to report on climate change. Al talks with PSC’s Ignatius Rigor about his research and the technology being used to gather data. read more » Research Highlights Polar Science Weekend is now called Climate Change // Curiosity Expo! Investigate the impacts that climate change has on the Earth, including the polar regions. Dive into this pressing topic through hands-on activities, live science shows, and more. February 28–March 1, 2020 read more » 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. read more » 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. read more » ABOUT PSC Axel Schweiger, PSC Chair, Welcome» The is a group of dedicated investigators conducting interdisciplinary research on the oceanography, climatology, meteorology, biology and ecology of the ice-covered regions on Earth and elsewhere in the solar system.
