A thermal ice corer was constructed in Iceland in 1968 and used for drilling a 108-m-deep hole in 1969. For shallow holes an electrical drive was added to a SIPRE coring auger in 1969 and this has been used for making a number of 10- to 20-m-deep holes.
A larger mechanical corer was then constructed for deep holes and used to drill a 415-m hole into the ice cap of Vatnajökull. The experience gained in this work and some possible refinements in the drilling technique are discussed.
