中国第30次南极科学考察队格罗夫山分队(CHINARE30,2013-2014年)利用雪地车载深层探冰雷达在东南极格罗夫山地区开展了测线总长度超过200 km大范围、高分辨率的冰厚及冰下地形调查,获得了哈丁山北部和萨哈罗夫岭与阵风悬崖之间详细的冰厚及冰下地形特征.通过对雷达数据分析表明,哈丁山北部区域平均冰厚为580 m,最大冰厚超过1 000 m,出现在该区域的东北方向,而东南方向冰厚相对较小;萨哈罗夫岭与阵风悬崖之间区域的平均冰厚为610 m,最大冰厚超过1 100 m,该区域槽谷发育十分成熟,槽谷形态近似呈U型.通过对雷达剖面影像的筛选和分析,推测在格罗夫山地区可能存在2个液态冰下湖泊.
China’s 30th Antarctic Scientific Expedition Team Grove Mountain Detachment (CHINARE30, 2013-2014) The use of snow-depth in-car ice-exploring radar in the Grove Mountains in the East Antarctic carried out a total length of more than 200 km line range, high Resolution of ice thickness and ice topographic survey to obtain the detailed ice thickness and ice topographic features between the north of Mount Harding and the Sakharov Ridge and gusts.Based on the radar data analysis shows that the northern part of Mount Harding With an average ice thickness of 580 m and a maximum ice thickness of more than 1 000 m, appearing northeast of the region, while ice thickness is relatively small in the southeast; the average ice thickness in the area between Sakharov and the gusts is 610 m , The maximum ice thickness is more than 1 100 m, and the troughs and valleys in this area are well developed and the shape of the trough is approximately U. By screening and analyzing the images of radar profiles, it is speculated that there may be 2 lakes under liquid ice in the Grove Mountains .
