With the official opening of China's Antarctic deep ice core first drill in the ice core room of Kunlun Station in China, the team successfully drilled a 3.83-meter-long ice core, marking a breakthrough in China's deep ice core drilling.
Deep ice core drilling is one of the frontier issues in earth science research. The choice of ice core drilling location, drilling techniques and logistics support capabilities all restrict the drilling of deep ice cores. The position of this time to drill the ice core will be the drill hole for obtaining a deeper ice core in the future. China plans to drill deep ice cores over 3,000 meters here in four years to obtain information on changes in the earth ’s climate and environment on a time scale of more than 1 million years. This will be a major breakthrough in the international deep ice core drilling research.
The highest point of the Antarctic inland ice sheet at the Kunlun Station, Ice Dome A, is not only the highest area of ​​the Antarctic inland ice sheet, but also recognized by the international community as the commanding height of Antarctic research. Since the ice cap does not move horizontally in the Ice Dome A, the ice core samples that can be drilled are chronologically comparable. The analysis and research can understand the meteorological and environmental information of different years during the formation of the ice core here.
Sun Bo, deputy team leader of the 29th Antarctic Expedition and captain of the Kunlun Station, said that ice core drilling has a profound impact on China ’s Antarctic scientific investigation. The success of the first deep-core drilling in Kunlun Station marks that China has taken an important step toward the goal of an ice-core research power.
