ARCTIC OCEAN - Crew members aboard the U.S. Coast Guard

ARCTIC OCEAN - Crew members aboard the U.S. Coast Guard Cutter Healy (WAGB-20) prepare to crane a device used to measure conductivity, temperature and depth into the water Wednesday, Sept. 19, 2018, approximately 100 miles northwest of Barrow, Alaska, in the Chukchi Sea. Approximately 30 scientists are 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 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.
