Coast Guard Cutter Healy conducts Arctic patrol in support of the Office of Naval Research

ARCTIC OCEAN – Test measurements from a sea glider are recorded on a computer Thursday, Sept. 20, 2018, aboard the Coast Guard Cutter Healy (WAGB-20) approximately 100 miles northwest of Barrow, Alaska, in the Chukchi Sea. Sea gliders are semi-autonomous submarines used to measure water conductivity, temperature, depth, oxygen and other measurements in the Arctic Ocean. Once deployed, the sea gliders are controlled by pilots in the Applied Physics Lab at the University of Washington in Seattle. Approximately 30 scientists are aboard the Healy 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 ice research in the Arctic.
