In July 2023, the Office of Naval Research (ONR) partnered with the 144th Airlift Squadron of the Alaska Air National Guard to deploy five different types of weather buoys across more than 1,000 nautical miles of the Arctic Ocean. Such deployments are critical for maintaining the Arctic Observing Network (AON), which provides observations for weather and ice forecasting and related research.

The 144th Airlift Squadron (the “Arctic Wolves”) and part of the 176th Wing (the “Arctic Guardians”) conducted the flights on a C-17 Globemaster III aircraft. In addition to personnel from the 176th Wing, participants included PSC’s Ignatius Rigor along with professors and scientists from the University of Maryland as well as ONR reservists.

The Pacific Science Center will be showing Arctic: Our Frozen Planet, an IMAX nature documentary by the BBC which PSC’s very own Eric Regehr helped film, and also appears in! Dr. Regehr will be doing a Q&A about polar bears after the showing on May 27. Regehr will answer questions from the audience after the morning and afternoon showings on Saturday, May 27. The Thursday, May 25, evening showing will feature a Q&A with UW glaciologist Ian Joughin. Admission is $5, or free for PacSci members.Narrated by Benedict Cumberbatch, Arctic: Our Frozen Planet is an epic adventure across the magical realm of snow and ice at the top…

Welcome, Dr. Laramie Jensen! Laramie Jensen is a high latitude chemical oceanographer who received her PhD in Oceanography from Texas A&M University in 2020. She studies micronutrient trace metals (like iron, manganese, copper, nickel, zinc, cadmium, lead, and more) and how their supply to the Arctic is changing. As a former CICOES postdoc here at UW, she collaborated with Drs Rebecca Woodgate and Cecilia Peralta Ferriz at the PSC to combine trace metal and macronutrient measurements with the high resolution hydrography surveys conducted as part of the Bering Strait Mooring Project. She is looking forward to continuing this project and expanding…
