在格陵兰岛的渗透区，冷铁质、水饱和铁质和冰层的混合热和结构框架可能很难用岩心钻穿透。在此，我们介绍了我们使用热水钻对渗透区坚硬层进行研究的经验。我们建造并部署了一套轻便、易于运输的系统，用于钻通直径约15厘米的横截面井眼，穿过整个硬柱厚度，深度超过100米。在钻井过程中，仪表化的钻杆提供了对岩石性能的科学测量。该系统成功地在潮湿和寒冷的混合条件下快速进入冰柱，很容易运输到现场和冰川表面，只需要一个小的现场工作人员就可以操作。这些钻孔非常适合于格陵兰渗透带的岩石过程的现场调查。
The intermixed thermal and structural framework of cold firn, water-saturated firn and ice layers in Greenland's percolation zone can be challenging to penetrate with core drills. Here, we present our experiences using a hot water drill for research on the firn layer of the percolation zone. We built and deployed a lightweight and easily transportable system for drilling a transect of ~15 cm diameter boreholes through the full firn column thickness, to depths exceeding 100 m. An instrumented drill stem provides a scientific measurement of the firn properties while drilling. The system was successful at gaining rapid access to the firn column with mixed wet and cold conditions, was easily transported to the site and across the glacier surface, and required a small field crew to operate. The boreholes are well suited for in situ investigations of firn processes in Greenland percolation zone.
