ARCTIC OCEAN – Scientists, engineers and crew members from the U.S. Coast Guard Cutter Healy (WAGB-20) prepare to unload gear Tuesday, Oct. 2, 2018, about 715 miles north of Barrow, Alaska, in the Arctic. 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, 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.
