On this day, 35 years ago, on March 3, 1990 (February 7, 1990, the International Trans-Antarctic Expedition Team reached the finish line. China participates in Antarctic exploration Antarctica is the last continent discovered in the world and the only continent where neither indigenous people live nor trees grow. Antarctica is the highest continent in the world. The reason why its continent is so tall is mainly because the ice and snow covering it is as thick as one to two thousand meters. Antarctica is the coldest region in the world, with an average annual temperature of-56¡æ. It is also the windiest and windiest area in the world. Since the discovery of the Antarctic continent in 1821, human exploration of the Antarctic has not stopped. At the beginning of this century, exploration and exploration of the hinterland of the Antarctic continent reached its climax. Briton Scott and Norway Amundsen led two expeditions in a race to reach the South Pole on foot. Amundsen was successful, but Scott and his party of five were all killed on the way back. The harsh natural conditions of Antarctica make every page of Antarctic exploration associated with sacrifice. After World War II, exploration of the Antarctic turned to scientific exploration. Around the Antarctic continent, more than 140 research stations have been established in more than 10 countries. But the hinterland of the Antarctic continent remains a mystery. Therefore, the United States and France jointly initiated and organized an expedition to complete the great initiative of crossing the Antarctic continent on foot for the first time in human history. This inspection team consists of one person from each of the five permanent members of the United Nations Security Council: China, the United States, the Soviet Union, Britain and France and Japan. Qin Dahe, associate researcher at the Lanzhou Institute of Glaciology and Permafrost, Chinese Academy of Sciences, joined the "1990 International Trans-Antarctic Expedition Team" on behalf of China. This inspection aims to show the world that the spirit of "cooperation, peace and friendship" followed by various countries in Antarctic exploration activities over the years will continue and arouse the international community's love and attention to the last primitive continent on earth. On July 28, 1989, Qin Dahe and other team members set out from the top of the Antarctic Peninsula and began their difficult journey from west to east. The criss-crossing ice crevices and snow-covered underground ditches were several meters or even tens of meters deep. The expedition team could only use their ski sticks to hit the ice and explore the way and move cautiously. Once encountering a snowstorm in the Antarctic, the visibility is only more than 10 meters, and the team members can only advance two to three kilometers a day. In the inspection team, only Qin Dahe and the former Soviet team members had scientific inspection tasks, so they had to work more than others. After dinner, while other team members were drinking coffee and resting, Qin Dahe carried an ice axe and axe to conduct glacier observation and sampling. hypoxia, low temperature, hunger, freezing, fatigue... Qin Dahe dug a few times with an ice pick and had to catch his breath. Even when he had the flu, he did not stop taking samples. During this trip to the Antarctic, Qin Dahe collected more than 800 bottles of snow samples, collected a large amount of data on Antarctic glaciers, climate, and environment, and successfully completed the observation of a large section of the snow layer from the Antarctic Peninsula through the Antarctic Point to the Peace Station. task. On March 3, 1990, at the Soviet Peace Station in Antarctica, the five-star red flag of China and the flags of the former Soviet Union, the United States, France, Britain and Japan fluttered in the cold wind. The six members of the "1990 International Trans-Antarctic Expedition Team" took more than seven months and traveled 5984 kilometers to finally reach the finish line. This is another victory of great significance that mankind has achieved since this century after reaching the poles of the earth, climbing Mount Everest, the top of the earth, and flying to the moon.
