Snow Dragon， encountering strange natural phenomenon， starboard overnight large iceberg

Successful completion of Russia "Shao Kaliski academicians" rescue trapped 52 passengers, "Snow Dragon", is still trapped in dense pack ice in Antarctica, part of pack ice up to 3 to 4 m thick. "Snow Dragon", about 1 km in length have been opened up in the ice "ice runway" breakout today or under favourable weather.

　About 21 km from the open sea has recently

On January 4, the journalist with the "Snow Dragon" front line was informed that sufficient supplies on board. "Snow Dragon" opens up about 1 km in length in the ice, "ice-runway" and wait for the weather conditions change. And January 6, there is a tropical cyclone in the area after wind may becomes westerly winds from the Southeast, ice would have changed, "Snow Dragon" select auspicious time to try to break through.

At present, the "Snow Dragon" decks look out, vision is full of white snow, nor to the surface. According to feedback information on site, the "Snow Dragon" closest to the open sea, about 21 km, surrounded by the dense sea ice around, including the ice pack and massive ice ridges, part of the sea-ice thickness of up to 3 m to 4 m, front, right behind the ice block, ice piled up high, far exceeding the xuelong ice-breaking capacity of 1 m.

Polar exploration said Qu Tanzhou, Director of the Office of State Oceanic Administration, changing Antarctic weather, weather may have good trends for January 6 is the "Snow Dragon" the opportunity to break through, but this time is very short, you need to "Snow Dragon" was prepared.

　Beautiful ice-breaker is expected to arrive on 12th

Currently trapped by Russia, "Shao Kaliski academicians" expedition ship have applied for United States icebreaker "North Star", to rescue them, are expected to arrive within 7 days.

Australia maritime safety authority said in a statement, United States Coast Guard has accepted the Board's request, visiting the Antarctic, helping "Shao Kaliski academicians", expedition ship "Snow Dragon" icebreaker out of danger.

Qu Tanzhou, the "North Star" in the 12th to reach China and Russia stranded vessels are in a region. Qu Tanzhou also said that if the self does not succeed, would help United States "Polaris" was out.

"Polaris" ice-breaker, is the world's most powerful icebreakers, continuous 1.8 meter thick ice-breaking at 3 knots speed, if you are using induction method of reversing, 6 meter thick ice-breaking. It is understood that the "Polaris", this time the trip to Antarctica will mostly perform for United States clean re-supply McMurdo Station route opened up the task.

　Focus

"Snow Dragon" breakout faces three big uncertainties

0.86 miles over ice floe overnight, starboard drift big icebergs

According to the Xinhua News Agency, according to the weather forecast, the night of 6th to 7th, this area will appear is overdue West wind, is expected to give the "Snow Dragon" brings out favourable weather conditions. "Snow Dragon", that is the broken Ice Breakout, get rid of this trouble? In fact faces three big uncertainties.

First, the strength of westerly and duration can blow away the thick ice floes? At present, the water district in the "Snow Dragon", on the starboard side, starboard retreated the most sincere, not sure West wind to "Snow Dragon" out, clear a passageway. Pack ice up to 3 to 4 metres thick, and the "Snow Dragon", only more than 1 meter of ice-breaking capability, currently loads, insufficient draught over the ship, breaking the ice on the propeller and rudder damage greatly.

Secondly, the West wind "Snow Dragon", the impact of icebergs around? At present, the "Snow Dragon" was bow wows a small iceberg, like a sword over their heads, "the sword of Damocles" threatening "Snow Dragon", security.

Third, bringing westerly winds and high pressure weather systems impact on the sea? Ship in these waters is the first in China, has recently encountered some called "exotic" phenomena of nature, we still can't explain. Why, for example, overnight "Snow Dragon" was sudden accumulation of thick pack ice over 0.86 miles, and starboard side appears a large iceberg drift? Why is right behind a big iceberg today doesn't seem to be moving?

November 7, 2013 "Snow Dragon", set foot on the Chinese 30th Antarctic expedition journey.

December 2 "Snow Dragon", ice arrived at the Zhongshan station, Antarctic ice shelf area.

December 19 Chinese polar expedition sailing ring for the first time in the history of the Antarctic continent.

December 25, Russia "Shao Kaliski, academician of" passenger ship trapped in Antarctica.

December 27 "Snow Dragon", advancing the area less than 10 nautical miles from Russian vessels in distress.

On December 31, "Snow Dragon", couldn't come close to the Russian vessel, decided to use a helicopter rescue.

January 2, 2014 "Snow Dragon" by helicopter, rescue 52 passengers on a Russian vessel.

January 3, pack ice rapidly expand the scope, the "Snow Dragon", trapped waiting to break through.

January 4 "Snow Dragon" opens up about 1 km in the ice "ice runway."

On January 6 the weather better, "Snow Dragon" will select the favorable opportunity to break through.

　The current situation

Team table tennis tournament, held vacuum

The trapped men in good condition, difficulty will continue after expedition

"Snow Dragon" investigation the Deputy team leader, Xu Ting said in media interviews, the "Snow Dragon", 101 players on the current emotional stability, out going scientific expedition.

Xu Ting said the "Snow Dragon" expedition, a total of 101 players on board, including 43 crew members. Everyone's still perform their respective duties, all positions will open a couple of times, after mobilization, we are all very serious and responsible. Organized a number of activities on board, we also held a table tennis game, we have a Southern University also will continue, with expert lectures. Overall feeling the team could still, there is no special exception, still as before, all aspects of the work has been relatively normal.

"Snow Dragon", after the disruption, planned investigations and tasks of navigation will inevitably be affected, following successful out is to continue its scientific research to come back to make adjustments? Xu Ting said, since if it works out, we will surely continue to visit, because one is to supply all its conditions are possible, second of all our instruments and equipment staff were very good. We originally expected on April 10 before returning to Shanghai. So there's still a lot of work to be done, and needs to be done. According to authorities wide nets

　　成功完成对俄罗斯“绍卡利斯基院士”号被困52名乘客救援的“雪龙”号，目前仍受困于南极密集浮冰区，部分浮冰厚达3米至4米。“雪龙”号已在浮冰中开辟了长约1公里的“破冰跑道”，今日或将根据有利天气突围。

　　距开阔海域最近约21公里

　　1月4日，记者通过与“雪龙”号前方连线获悉，船上补给物资充足。“雪龙”号在浮冰中开辟了长约1公里的“破冰跑道”，等待天气条件转变。1月6日和7日，该海域将有一股热带气旋经过，风向可能会由东南风变为西风，浮冰也会因此产生变化，“雪龙”号将选择有利时机尝试突围。

　　目前，从“雪龙”号甲板往外望去，视野里全是白色冰雪，看不到水面。根据现场反馈回来的信息，“雪龙”号距离开阔海域最近约21公里，周围被密集海冰包围，包括大块浮冰和大面积冰脊，部分海冰厚度达3米至4米，前方、右后方各有冰山阻挡，海冰堆积很高，远超雪龙船1米的破冰能力。

　　国家海洋局极地考察办公室主任曲探宙说，南极天气瞬息万变，1月6日天气可能有转好趋势，是“雪龙”号突围的机会，但这个时机非常短暂，需要“雪龙”号做好准备。

　　美破冰船预计12日抵达

　　目前被困的俄罗斯“绍卡利斯基院士”号科考船已经申请美国破冰船“北极星”号前往救援，7天内将有望到达。

　　澳大利亚海事安全局发布声明称，美国海岸警卫队已经接受了该局的请求，前往南极，帮助“绍卡利斯基院士”号科考船与“雪龙”号破冰船脱险。

　　曲探宙表示，“北极星”号在12日前后能够到达中国和俄罗斯受困船只所在的区域。曲探宙还表示，如果自救没有成功的话，将求助美国“北极星”号脱困。

　　“北极星”号破冰船是世界最强的破冰船，能以3节航速连续破1.8米厚冰，如果用倒车冲击法，可破6米厚冰。据了解，“北极星”号这一次的南极之行主要将执行为美国清理麦克默多站提供补给开辟航路的任务。 综合人民网、央广网报道

　　“雪龙”突围面临三大不确定性

　　一夜之间被浮冰推移0.86海里，右舷出现漂移大冰山

　　据新华社电 根据气象预报，6日晚至7日凌晨，这一海域将会出现期盼已久的西风，有望给“雪龙”号脱困带来有利的气象条件。“雪龙”号果真能一举破冰突围、摆脱困境吗？事实上面临三大不确定性。

　　首先，西风的强劲程度和持续时间能否吹散厚重的浮冰？目前，清水区在“雪龙”号的右舷方向，但右舷的浮冰最为厚重，不确定西风能否给“雪龙”号脱困清理出一条通道。浮冰厚达3至4米，而“雪龙”号只有1米多的破冰能力，目前船上空载、吃水不够，持续破冰对螺旋桨和舵损伤很大。

　　其次，西风对“雪龙”号周围的冰山有何影响？目前，“雪龙”号船头横亘的一座小冰山，如同一把悬在头顶的“达摩克利斯之剑”，时刻威胁着“雪龙”号的安全。

　　第三，带来西风的高压天气系统对这片海域有何影响？我国船舶是第一次航行在这片海域，对近来遭遇到的一些堪称“奇异”的自然现象，大家还无法解释。例如，为什么一夜之间“雪龙”号被突然堆积的厚重浮冰推移了0.86海里，而且右舷出现一座漂移的大冰山？为什么右后方的一座大冰山今天又好像不动了？

　　●2013年11月7日 “雪龙”号踏上中国第三十次南极科考征程。

　　●12月2日 “雪龙”号破冰抵达南极中山站外陆缘冰地带。

　　●12月19日 实施中国极地科考史上首次环南极大陆航行。

　　●12月25日 俄罗斯“绍卡利斯基院士”号客轮受困南极。

　　●12月27日 “雪龙”号挺进离俄遇险船只不到10海里的区域。

　　●12月31日 “雪龙”号无法靠近俄船只，决定动用直升机营救。

　　●2014年1月2日 “雪龙”号用直升机营救俄船只上52名乘客。

　　●1月3日 浮冰范围迅速扩大，“雪龙”号被困等待时机突围。

　　●1月4日 “雪龙”号在浮冰中开辟长约1公里的“破冰跑道”。

　　●1月6日 天气有好转趋势，“雪龙”号将选择有利时机突围。

　　■ 现状

　　队员举行乒乓球赛减压

　　被困人员状态良好，脱困后将继续科考

　　“雪龙”号考察队副领队徐挺接受媒体采访时表示，“雪龙”号上101名队员目前情绪稳定，脱困后将继续科学考察。

　　徐挺表示，“雪龙”号科考船上一共有101名队员，包括43名船员。大家还是各司其职，各个岗位也开过几次会，经过动员，大家都非常认真负责。船上组织了很多活动，晚上我们还举行了乒乓球比赛，我们特设的南极大学还照常进行，有专家讲课。总体感觉队员还是可以，没有特别的表现异常，基本还是跟以前一样，各方面的工作还是比较正常。

　　“雪龙”号受阻以后，其实原计划的各种考察和航行任务肯定会不可避免地受到影响，成功脱困之后是要继续去进行科考还是要回国进行调整？徐挺对此表示，如果成功脱困以后，我们肯定要继续考察，因为一个是我们的补给各方面的条件都是可以的，第二个我们所有仪器设备人员状况都非常良好。本来我们预计是4月10日才能返回上海。所以这当中还有大量的工作要做，而且必须要做。 据央广网
