U.S. Coast Guard icebreaker frees boat stranded near Antarctica

‘The situation was dire,” said Coast Guard Chief Warrant Officer Allyson Conroy. “Had the Polar Star not reached the Chieftain, it would have had to winter in the ice.”

In January 2014, the cutter was deployed to help break through ice that had trapped the Russian ship Akademik Shokalskiy and China’s Xue Long and left them temporarily stranded.
