Douglas Channel is part of a complex network of fjords on the Pacific north coast of British Columbia, Canada, an area in which fjords formed under the influence of westward-moving ice of the Cordilleran Ice Sheet (Barrie et al. 2014). The Douglas Channel fjord system (Fig. 1a) extends from the Pacific coast to the town of Kitimat located 150 km inland, and has a maximum depth of 690 m. The fjords are developed within the Coast Range, which has peaks extending up to 1500 m in the study area. The fjord system is located on the North American Plate, east of its boundary with the Pacific Plate. The region is subject to heavy precipitation (>2700 mm a−1 at Kitimat) and melt from snow pack in the interior.
