BERING SEA – Peter Koski prepares an ice tethered profiler for Arctic deployment Saturday, Sept. 15, 2018, in the science lab aboard the Coast Guard Cutter Healy (WAGB-20) in the Bering Sea. Koski is one of 30 scientists aboard the Healy deploying sensors and autonomous submarines in the Arctic to study stratified ocean dynamics and how environmental factors affect the water below the ice surface. The Healy is one of two ice breakers in U.S. service and is the only military ship dedicated to conducting ice research in the Arctic.
