On April 22, 2020, Qiao Gang and Hao Tong, professors from College of Surveying and Geo-Informatics at Tongji University, arrived at the dock of China's polar research base with China’s research icebreaker “Xuelong II" after successfully completing the scientific research mission in China's 36th Antarctic expedition,

　　During unloading at Zhongshan station, the remote sensing team from our college provided real-time image analysis data of fixed ice conditions at Zhongshan station for the investigation team, planned the ice-breaking route of ships and ice transport routes of fleets, avoided dense icebergs and ice crevasses, and opened the "ice road". At the same time, Qiao Gang and Hao Tong, as the expedition team members, made on-site observation by UAV and ice penetrating radar in the Antarctic and provided high-resolution on-site ice map and ice thickness information, which was important information support for the expedition team's on-site decision-making and operation implementation. It made an important contribution to the first "tough battle" of China's 36th Antarctic expedition. After the unloading task, the team wrote specially to thank Tongji University for its support.

　　The mission of this expedition is to carry out polar ground-to-air observations on the contribution of the Antarctic ice sheet to mass balance and sea level rise at Zhongshan Station and Taishan Camp. Among them, the tasks such as mass balance of inland traverse route, coordinated observation of mass balance surface of Zhongshan Station satellite ice sheet and remote sensing product inspection are particularly important. Qiao Gang conducted observation of key parameters of mass balance of surrounding ice sheet, unmanned aerial vehicle mapping and surface microtopography observation of the leading edge of Dalke Glacier, and verification and evaluation of accuracy of polar satellite, etc. at Zhongshan station. Due to his great contribution, Qiao Gang was awarded the title of "Excellent CPC Party Member" by the team of China's 36th Antarctic expedition. On behalf of Tongji University, it was the second time Qiao Gang had participated in China’s Antarctic expedition.

　　Professor Hao Tong laid the photon detection target of a new single-photon polar altimeter satellite at Taishan Camp, carried out a new UAV-borne ice penetrating radar flight test, providing a new method for the measurement of sea ice thickness and the detection of subglacial shallow structures and crevasses, installed and maintained several angle reflectors and a temperature chain, which can provide continuous temperature observation data at a depth of 20 meters under the snow surface. Meanwhile, he collected a number of vehicle-mounted ice penetrating radar surveys, obtained the UAV orthophoto and digital elevation data of 3*3km in Taishan Camp area, helped in accumulating the image data of Taishan Camp area.

　　The observation data from the expedition will help to build ground, satellite and aerial-based observation systems covering different types of regions, including the oceanic and polar regions, achieve dynamic monitoring of key polar elements. It will play an important role in supporting the research and development of polar total-element data product series with independent intellectual property rights, testing its model support capability, reducing the uncertainty of global change prediction, and displaying the data products for trans-polar key change process and coupling mechanism.

　　Tongji University has been undertaking major polar research projects in China for a long time. It has obtained important research results, making continuous contribution to China's polar scientific research.
