Abstract This technical 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. More efficient than the conventional CRREL coring kit, the 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. Copyright © 2005 John Wiley & Sons, Ltd.
