中国中山站-昆仑站冰盖考察断面所在的伊丽莎白公主地兰伯特冰川流域的冰川学环境仍是人类所知甚少的区域.由冰雷达探测获得的冰盖内部复冻结冰是表征冰盖物质平衡的一个重要结构.针对中山站-昆仑站内陆冰盖考察断面,2012/2013年中国第29次南极考察队使用一个中心频率为150 MHz的新探冰雷达系统进行了冰盖内部复冻结冰探测,收集了整个断面~1300 km的雷达数据,获得了该断面的复冻结冰分布.一个与在冰穹A地区所发现的复冻结冰结构相似的区域由雷达图像所揭示.分析表明,沿着雷达测线,该复冻结冰区域长约10 km,平均厚度约300 m,其位置距离中山站1044~1056 km;复冻结区所在的冰盖区域的表面高程约为3610~3750 m,冰厚为910~2250 m,其冰厚显著小于最早发现复冻结冰的冰穹A区域的冰厚.
The glaciological environment of the Lambert Glacier Basin, where the ice section of the Zhongshan Station of China’s Kunlun Station is located, is still unknown to human beings. The ice-in-ice inside the ice cap An important structure of material balance.Aiming at the cross-section of inland ice sheet of Zhongshan Station-Kunlun Station, the 29th Antarctic expedition team in 2012/2013 used a new ice-exploring radar system with a center frequency of 150 MHz to perform inter-freezing Ice acquisition, which collected radar data from ~ 1,300 km across the section, obtained the re-freeze icing distribution for this section, and a region similar to the re-freeze icing structure found in Dome A was revealed by the radar image.Analysis showed that, The ice-freezing area is about 10 km long with an average thickness of about 300 m and its location is 1044 ~ 1056 km away from Zhongshan Station. The surface elevation of the ice-covered area where the re-freezing junction is located is about 3610 ~ 3750 m, The ice thickness is 910-250 m, and its ice thickness is significantly smaller than the ice thickness in the ice dome A region, where the ice-frozen area was first discovered.
