SYDNEY/MOSCOW — A Chinese icebreaker trying to reach a Russian ship trapped in Antarctica has been halted by thick ice within sight of the stricken vessel and an Australian ship was now trying to help, an Australian maritime rescue agency said on Saturday. The Snow Dragon was one of three icebreakers sent to free the MV Akademik Shokalskiy, which became stranded far south of Tasmania on Tuesday in ice driven by strong winds. “Since the thick ice exceeds the ship's icebreaking capabilities and an upcoming cyclone will exacerbate icy conditions, we have to temporarily stall the ship,” Snow Dragon captain Wang Jianzhong told the Xinhua news agency. The trapped ship, the Akademik Shokalskiy, left New Zealand on Nov. 28 on a privately funded expedition to commemorate the 100th anniversary of an Antarctic journey led by famed Australian explorer Douglas Mawson. The ship's 74 passengers include scientists and tourists, many of them Australian, and what the Russian Foreign Ministry said were 22 Russian crew members. The Australian Maritime Safety Authority (AMSA), told Reuters that the Snow Dragon would remain on standby until the Australian icebreaker the Aurora Australis reaches the MV Akademik Shokalskiy. — Reuters
