Drilling techniques and drill development
At the Centre for Ice and Climate, we have 3 different ice core drills essentially characterized by the depth to which they can drill. The deeper the drill has to go, the greater the drilling system size, weight and complexity.
The hand auger is used for collecting 74 mm diameter cores from the top 10 m of the ice cap. It is operated by one person and weighs only 80 kg. Read more
In the upper 350 m of ice where drilling liquid is not necessary, the shallow drill can be used, producing up to 50 m of 74 mm diameter core per day. Read more
The deep drill can operate at any depth and can be used in liquid-filled holes. It is slower to operate but can retrieve core sections of up to 4 meters. Read more
