Coast Guard Rescues Fishermen Trapped in Ice
The Coast Guard Cutter Polar Star tows the fishing vessel Antarctic Chieftain in the Southern Ocean, Feb. 15, 2015. Polar Star's crew assisted the Antarctic Chieftain after the vessel was disabled and trapped in the thick Antarctic ice for almost two weeks. The Polar Star is the nation’s only active heavy icebreaker, which is capable of breaking through ice as much as 20-feet thick. U.S. Coast Guard video by Petty Officer 1st Class George Degener.
