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
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
-
The shallow drill
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
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
