摘要
The 2012/2013 Chinese Antarctic Research Expedition （CHINARE） ＇s inland traverse from Zhongshan station to Kunlun station on the East Antarctic ice sheet provided an opportunity to reveal englacial freeze-on ice using ice-penetrating radar. A radar dataset along the profile was collected using a new ground-based radar system with a high frequency of 150 MHz. A typical example of a freeze-on ice structure was revealed in the radar images, similar to that found in the Dome A region. The subglacial stratigraphy showed a new freeze-on ice zone with a length of 10 km near the ice-bedrock interface along the traverse, located 1,044-1,056 km from the coast.
