美国冰钻计划（IDP）开发了一种新的钻井系统，可以快速钻穿覆冰，收集冰下岩石岩芯。Agile亚冰地质（ASIG）钻探系统能够连续钻探700米的冰。可根据需要采集间歇冰芯样品。十多米的冰下基岩和未固结的冷冻沉积物岩心可以用电缆取心。2016- 2017年，该钻井系统的功能在南极洲的pirit Hills进行了验证，在150米的冰层下回收了8米高质量的连续花岗岩岩心。论述了该钻井系统的研制、特点和性能。
A new drilling system was developed by the US Ice Drilling Program (IDP) to rapidly drill through overlying ice to collect subglacial rock cores. The Agile Sub-Ice Geological (ASIG) Drill system is capable of drilling up to 700 m of ice in a continuous manner. Intermittent ice core samples can be taken as needed. Ten-plus meters of subglacial bedrock and unconsolidated, frozen sediment cores can be drilled with wireline core retrieval. The functionality of the drill system was demonstrated in 2016-17 at the Pirrit Hills, Antarctica where 8 m of high-quality, continuous granite core was retrieved beneath 150 m of ice. The particulars of the drill system development, features and performance are discussed.
