Chinese Deep Ice Core drilling in Dome A，Antarctica

        The Polar Research Center of Jilin University began to participate in China's Antarctic scientific expedition mission in 2011, and carried out the Antarctic field mission of Chinese deep ice core drilling science project in Dome A, Antarctica. Since 2011, the center has sent 21 people to participate in all six Antarctic field drilling work of the project. Completion of pilot hole construction, deep ice core drilling system setup, deep ice core drilling, on-site drilling system maintenance and repair, drilling site electrical system upgrade, ice core processing and analysis. So far, the total core drilling depth has reached 803 m. The Antarctic Dome A deep ice core drilling team of Jilin University won the honorary title of "Advanced Collective for the 30th anniversary of Chinese Polar Expedition".
