The crew of the U.S. Coast Guard Cutter Polar Star breaks the ice around the motor vessel Ocean Giant prior to the vessel’s planned departure from the National Science Foundation’s McMurdo Station, Feb. 1, 2017.
The Polar Star’s crew is responsible for providing a safe channel through the Antarctic ice for the resupply ships that visit the station.
