ARCTIC OCEAN – Joe Talbert (left) and Dr. Craig Lee pull a sled of scientific equipment across the Arctic ice Wednesday, Oct. 3, 2018, about 715 miles north of Barrow, Alaska. Lee is the lead scientist aboard the U.S. Coast Guard Cutter Healy (WAGB-20) in the Arctic. Lee is leading a team of about 30 scientists and engineers studying 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)
