ARCTIC OCEAN – Peter Koski tries to block the sun in order to view his computer screen Sunday, Sept. 30, 2018, about 350 miles northeast of Barrow, Alaska, in the Arctic. Koski is one of about 30 scientists and engineers aboard the U.S. Coast Guard Cutter Healy (WAGB-20) to deploy sensors, buoys and semi-autonomous submarines in the Arctic to study stratified ocean dynamics and how environmental factors affect the water below the ice surface for the Office of Naval Research. The Healy, which is homeported in Seattle, is one of two ice breakers in U.S. service and is the only military ship dedicated to conducting research in the Arctic. (NyxoLyno Cangemi/U.S. Coast Guard)
