China’s research vessel and icebreaker Xuelong has entered an area of clear water, after more than ten hours spent breaking up ice. A change in wind direction loosened the floes packed around the vessel, providing an 80-meter stretch of water for the Xuelong to navigate in. The ship is continuing to collect data of geological conditions.

It’s now waiting for favorable weather to return. The icebreaker had been trapped in the area since Friday. On Thursday, its helicopter had evacuated all 52 passengers from the stranded Russian ship Akademik Shokalskiy to the Australian icebreaker Aurora Australis.

The Australian Maritime Safety Authority, the coordinator of the rescue operations, has sent a thank-you note to the Chinese Ambassador to Australia. It commends Xuelong’s contribution and professionalism in the mission.
