Once upon a time, Antarctic was like a mysterious alien world to human beings, until expedition teams from various countries landed and explored this glacial continent, it began to be no longer far away from us. On the Antarctic continent, which covers an area of 14 million square kilometers, Dome A with an altitude of 4,093 meters is the highest point of the Antarctic inland ice sheet, and has always been called the "inaccessible pole". After Li Yuansheng, an alumnus of Nanjing University's 1977 Department of Geology, and the first station manager of Kunlun Station , arrived as the team leader, he not only put the five-star red flag on this historically and geographically significant position, but also It has set a new record for the human polar scientific examination.
In Antarctica, where there is a Chinese Antarctic expedition team, there is a five-star red flag; where there is a five-star red flag, the pride and pride of the Chinese are flying. As the limit of human existence, Antarctica has low air pressure, low temperature and low oxygen content. It is amazing that ordinary people can go there once in their lifetime. However, Li Yuansheng's work place is in the Antarctic. He has been to the Antarctic more than ten times, and he has been in the company of ice and snow all day, always accompanied by danger. Although he has an indissoluble bond with Antarctica, he is actually a "late comer" to Antarctica.
htmlAt the age of 334, Li Yuansheng first became interested in Antarctica. At the age of 39, he officially "changed his career". In 1996, at the age of 40, he was sent to Japan as an exchange scholar to participate in their inland ice cap research. It was his first visit to Antarctica. When set foot on the Antarctic continent for the first time, Li Yuansheng was shocked by the climate here: "It feels like being thrown out of human society." In the environment of minus tens of degrees, he has to dig outdoors for several hours every day. Snow pits, so that digging snow pits became a psychological obstacle in his later Antarctic expeditions.But also thanks to such tempering, he was able to sum up an expedition report of more than 30,000 words after returning to China, which provided great help to China's later Antarctic inland expedition.
From 1998 to 1999, in China's 15th Antarctic Scientific Expedition, Li Yuansheng led the team to advance 1,100 kilometers into the Antarctic inland ice sheet with domestic sleds. At that time, there was no plane as a means of transport for the Chinese polar scientific expedition. During an unloading on ice, Li Yuansheng drove a transport vehicle at the front of the team. The truck happened to pass through a tidal crevice, a crack suddenly appeared on the ice surface, and the rear of the truck sank several tens of centimeters. Dangerous situations like this happen from time to time, but Li Yuansheng and his colleagues are not afraid of difficulties and dangers, deal with them calmly, and turn them away time and time again. The
South Pole has not only the blue and deep ocean , the magical iceberg, the penguin with a graceful posture, but also the four most important "points", namely the pole, the freezing point, the magnetic point and the high point. Among them, the establishment of a scientific research station at the highest point is of great significance. This area is most likely to find the oldest ice core on the earth, and the indicators observed here are also more convincing for global climate change. Li Yuansheng took over the task of building the Kunlun Station at the highest point in the Antarctic.
On January 9, 2009, the construction of Kunlun Station, the highest point of the Antarctic continent at an altitude of 4,093 meters, began in China. After nearly a month of hard work, at 12:25 on February 2, my country's first Antarctic inland research station, Kunlun Station, officially opened, and Li Yuansheng served as the first stationmaster of Kunlun Station.
Li Yuansheng has undertaken many Antarctic on-site research tasks as the person in charge of the on-site scientific research.In China's first expedition to the Emory Ice Shelf, he led the team to establish the China Emory Ice Shelf Glaciology Observation System, and drilled a 302-meter ice core, which is the largest record obtained in the international Antarctic Ice Shelf research so far. A complete and best-quality ice shelf ice core has opened up a new field of scientific research in China's Antarctic. samples and important field observations.
From 1984 when China's first Antarctic expedition team planted the five-star red flag on the ground of the Antarctic for the first time, China's polar expedition has gone through 37 years of development. Generations of Antarctic scientific expedition workers have witnessed the process of China's Antarctic expedition from scratch, from small to large, and from big to strong. In 2019, Li Yuansheng emotionally expressed his enthusiasm for scientific investigation work when he was a guest on CCTV " talk " "My Times Answers" series, "We are very small, and under the support of a powerful country, we are fortunate to After doing this, I became a participant, witness, and practitioner."
