Document DetailsThermal Core Drilling in Ice Caps in Arctic Canada
|Periodical/Journal:||Ice-Core Drilling (ed. J.F. Splettstoesser), University of Nebraska Press, Lincoln, NE|
The CRREL shallow-hole thermal coring drill has been used to drill a 121-m borehole through the Meighen Ice Cap and three holes (230, 299 and 299 m) in the ice cap on Devon Island. Three of the four holes reached bedrock; in the 230-m hole, the drill became frozen in and was lost. Operating conditions, the performance of the drill, and problems encountered are described.
