环绕着南极大陆陆缘海冰隐伏冰裂缝发育,严重威胁我国南极科考海冰运输的安全.探地雷达可以精确、快速、有效探测海冰层序空间结构、隐伏冰裂缝两翼形态、冰裂缝的分布范围等关键要素.探冰队对拟选东部线路约22 km进行雷达探冰作业,新发现规模较大隐伏冰裂缝5条.评估了中国第30次南极科考队海冰卸货运输路线,为科考船“雪龙”号上大量物资、科考设备和重型装备安全运抵中山站保驾护航. The development of concealed ice cracks around the Antarctic continental margin sea ice severely threatens the safety of the Antarctic expeditionary sea ice transport.The ground penetrating radar can accurately, rapidly and effectively detect the spatial structure of the sea ice sequence, Of the distribution of the key elements such as ice-breaking team on the proposed eastern route about 22 km for the radar exploration work, the discovery of a large hidden ice cracks 5. Evaluation of China’s 30th Antarctic expedition team sea ice unloading transport routes , For the test boat “Snow Dragon ” on a large number of supplies, expedition equipment and heavy equipment arrived in Zhongshan station safe escort.
