China's Antarctic expedition: ice core drilling exceeded 800 m mark
CNS, Changchun, April 18 (reporter Li Yanguo)-33rd Antarctic scientific expedition of Kunlun station, China's party branch Secretary of zhangnan 18th, an associate professor of Jilin University in Changchun, presented to the media, Chinese expedition in the Antarctic ice sheet broke through the 800 m drilled mark the highest point area and gets deep ice cores, the results from scientific inference Earth's climate changes, trends, and one step closer.
The same day, 33rd Antarctic scientific expeditions of China Jilin University scientific expedition team held a press conference, the team participates in Antarctic Kunlun station Dome area (also known as the "dome a," of the Antarctic ice cap high point) deep ice core drilling and scientific missions.
Nan introduced, China was the world's first in the Antarctic ice cap high point regional countries for deep ice core drilling project. "It can be said that every drilling down into the 1 m is a new breakthrough. ”
Computed from the first Antarctic expedition since 1984, China has entered the Antarctic expedition for 33 years, is being built on the Antarctic continent at great wall station and Zhongshan station, Taishan station, Kunlun station four sites, one Antarctic expedition among the country.
Antarctic Kunlun station Dome area is considered to be under natural conditions, the coldest place on Earth, and universal drilling deep ice cores in Antarctica the most ideal location, where you can obtain more than 1 million year old ice core.
At present, China has in the Antarctic Dome a area 3000 m deep ice-core drilling of the long-term plan. "There is equivalent to the Earth in a time container, you can deduce the planet's climate changes and trends. "Zhang Nan said.
At low pressure, low oxygen and high altitude of the Antarctic Dome a area, formed the scientific strength of Jilin University in China the 28th Antarctic scientific expedition began, participating in all the deep ice core drilling project.
"The biggest task this year is to put a shift, two shifts, gradually turned into three shifts. "Zhang nan says, so you can work 24 hours a day, days a, enhances the working efficiency.
Continue on the basis of lessons learned, this year's Antarctic expedition team successfully breaking through the 800 m mark in Antarctic Dome a area. "600 meters to 800 meters internationally recognized as find it difficult drilling areas, this year we are also evacuated last day before break through the depth of the Kunlun station, laid the Foundation for later work. "Zhang Nan introduced.
It is understood that the team back to China after a short trim will have to continue to invest in new work. "We still have a lot of work to do, such as training new people, train staff, establish a sound scientific mechanism, which is the immediate problem. "Zhang Nan said.

中国南极科考：冰芯钻探突破800米大关
中新网长春4月18日电  (记者 李彦国)中国第33次南极科学考察队昆仑站党支部书记、吉林大学副教授张楠18日在长春向媒体介绍，中国科考队在南极冰盖最高点区域突破了800米钻探大关并获取深冰芯，这个成果距离科学推演地球气候变化规律、趋势又迈近了一步。
　　当日，中国第33次南极科学考察吉林大学科考队举行媒体见面会，这支队伍主要参与南极昆仑站Dome A地区(又称“冰穹A”，系南极冰盖最高点)深冰芯钻探科学任务。
　　张楠介绍，中国是世界上第一个在南极冰盖最高点区域进行深冰芯钻探工程的国家。“可以说，每向下钻进1米都是一个新的突破。”
　　自1984年首次南极科考算起，中国已经进入南极科考33年，在南极大陆上相继建成长城站、中山站、泰山站、昆仑站四个站点，跻身南极科考大国之列。
　　南极昆仑站Dome A地区被认为是地球上自然条件下最寒冷的地方，也是世界公认的钻取南极深冰芯最理想的地点，在那里可以取得超过100万年的古老冰芯。
　　目前，中国有在南极Dome A地区打3000米深冰芯钻孔的长期计划。“那里相当于是地球的一个时间容器，可以推演地球的气候变化规律和趋势。”张楠说。
　　在低气压、低氧、高海拔的南极Dome A地区，吉林大学组建的科考力量自中国第28次南极科学考察开始，参与了所有的现场深冰芯钻探工程。
　　“今年最大的任务就是把以前的一班制、两班制，逐渐地变成三班制。”张楠说，这样可以全天24小时无休的工作，提高工作效率。
　　在不断总结经验的基础上，今年南极科考队员在南极Dome A地区成功突破800米大关。“600米到800米是国际上公认的比较难钻进的区域，今年我们也是在撤离昆仑站的最后一天才突破这个深度，为后面的工作奠定了基础。”张楠介绍。
　　据了解，刚刚返回中国的科考队员在短暂修整之后便要继续投入新的工作中。“我们后面还有很多工作要做，比如培养新人、培养队伍、建立起一个完善的科考机制，这都是迫在眉睫的问题。”张楠说。
