Description :
This technique note presents a light drill specially designed for coring in permafrost. The drill was improved over several years at Université Laval's Centre d'études nordiques. This equipment allows total-length recovery of cores 10 cm in diameter nearly without alteration, and works in most kinds of frozen soils. Drilling is possible to 7 m using a two to three-person operating crew.
