China News Service Snow Dragon on April 6 (Reporter Yu Lin) lasted more than 160 days and traveled more than 28,000 nautical miles. The 28th Antarctic expedition in China experienced the turbulent waves of the three oceans and the difficult navigation of the ice floes. The low temperature and coldness of the Antarctic continent and the lack of oxygen in the plateau have completed various construction inspection missions for Zhongshan Station, Kunlun Station, Great Wall Station and Southern Ocean, and achieved breakthrough results in many fields such as astronomy, glaciers and Southern Ocean inspection. .


  At Kunlun Station on the highest point of the Antarctic inland, 26 inland expedition members overcame the plateau anoxic and low temperature and cold, successfully completed the installation of the 100-meter guide tube of the deep ice core drilling hole of Kunlun Station, and drilled it. The 120-meter ice core provides a valuable sample for glaciology and climatology in the highest area of the Antarctic ice sheet. At the same time, this is China's first deep ice core drilling in the Hail A area.


  The successful installation of the deep ice core drilling hole guide tube at Kunlun Station is a milestone in the deep ice core drilling project, which indicates that the most critical part of the preparation work for deep ice core drilling has been successfully completed.


  At Kunlun Station, the installation of the first Antarctic survey telescope independently developed by China was completed. The telescope is equipped with the world's largest monolithic charge-coupled device, which can search the universe for multiple times in a wide range of times within 24 hours. The telescope is the first telescope in the Antarctic inland that can be remotely controlled, with pointing tracking and auto focus. The installation and commissioning of this Antarctic survey telescope was successful, marking China's important step in the field of Antarctic astronomical science.


  In the high seas and waves of the Antarctic Peninsula, the pilot project of China's Aral and Arctic Environment Comprehensive Investigation Project was carried out for the first time, and a comprehensive survey of multi-disciplinary oceans such as physical oceanography, marine geology, marine geophysics, ocean chemistry, and marine biological ecology was carried out. The investigation of the Antarctic Peninsula waters filled the gaps in the comprehensive observation of the large, vertical and deep sections of the Southern Ocean. This is also the first comprehensive observation in China with clear objectives, strong continuity, wide coverage and outstanding emphasis.


  For the first time, China successfully deployed and recovered two submarine seismographs in the Antarctic waters. The seismograph recorded earthquakes in the Antarctic continent and its surrounding waters for more than two months. This is the first time that China has conducted submarine seismic observations in the Antarctic.


  For the first time, China completed the long-range autonomous walking test of the robot in the Antarctic ice sheet. After more than two months of hard trials, the long-range polar roaming robot completed autonomous walking in the Antarctic ice sheet for 30 kilometers.


  At the same time, China completed the first low-altitude aerial photography of the Dalke Glacier area on the edge of the Antarctic ice sheet, providing basic mapping for the mapping of positive imagery in the area. This Antarctic survey successfully carried out a comprehensive geophysical survey including ocean gravity, magnetic force and water depth measurement in the marine geophysical key investigation area on the northern margin of the Antarctic Peninsula. This is the first comprehensive geophysical survey in the Antarctic waters in China in the past 20 years. .


  China's 28th Antarctic expedition carried out 31 scientific investigations at Zhongshan Station, Great Wall Station, Kunlun Station and Southern Ocean, among which breakthroughs were made in the fields of glaciers, astronomy and oceans. On the stage of the Antarctic, it fully demonstrated the image and status of China's great powers and powers, and laid a good foundation for the smooth development of China's polar inspection of the 12th Five-Year Plan (2011-2016).


  Looking ahead, China will acquire 3,000 meters of deep ice core at the highest point of the Antarctic inland ice sheet, in order to obtain an ice core containing 1 million years of paleoclimate records, which will fill China's gap in this field and will make China's glaciers Academic field research has entered the forefront of the international arena. The first Antarctic survey telescope installed at the Kunlun station of this Antarctic survey is the predecessor of the Antarctic Observatory. In the next few years, China will install two other Antarctic survey telescopes at the Kunlun station on the “ice cover”. (Finish)
