Rapid Access Ice Drill: a new tool for exploration of the deep Antarctic ice sheets and subglacial geology
ABSTRACTA new Rapid Access Ice Drill (RAID) will penetrate the Antarctic ice sheets in order to create borehole observatories and take cores in deep ice, the glacial bed and bedrock below. RAID is a mobile drilling system to make multiple long, narrow boreholes in a single field season in Antarctica...

RAID is a mobile drilling system to make multiple long, narrow boreholes in a single field season in Antarctica.
