The U.S. Coast Guard Cutter Polar Star and its crew

The U.S. Coast Guard Cutter Polar Star and its crew depart Sydney, Australia, after a multi-day port call to top off needed ship supplies prior to heading south for Antarctica, Jan. 1, 2017.
The crew of the Polar Star is operating in Antarctica as part of Operation Deep Freeze, the U.S. military’s component of the civilian-managed U.S. Antarctic Program, and the Coast Guard, working with personnel from the Air Force and the Navy, help resupply Antarctic research stations for the upcoming year.
