When drilling into subglacial bedrock, drill operators commonly encounter basal ice containing high concentrations of rock debris and melt water. As such conditions can easily damage conventional ice drills, researchers have experimented with carbide, diamond, and polycrystalline diamond compact drill bits, with varying degrees of success. In this study, we analyzed the relationship between drilling...
The Gamburtsev Mountains, located in East Antarctica, is the direct geomorphological cause of the formation of Dome A. Drilling the core of the Gamburtsev subglacial mountains is one of the primary goals of modern polar research, which is important to understand its formation and evolution process, the ice sheet formation of Dome A, glacial motion, climate change, and so on. This paper describes the...
