ARCTIC OCEAN – U.S. Coast Guard Petty Officer 3rd Class Shannon Eubanks stands polar bear watch Tuesday, Oct. 2, 2018, about 715 miles north of Barrow, Alaska. Eubanks is stationed aboard the Coast Guard Cutter Healy (WAGB-20) out of Seattle, and as a member of the ice rescue team, Eubanks stands watch to protect members and scientists from polar bears. The Healy is underway in the Arctic with about 100 crew members and 30 scientists to deploy sensors and autonomous submarines to study stratified ocean dynamics and how environmental factors affect the water below the ice surface for the Office of Naval Research. The Healy 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)
