A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in August 2013 in the Disko Fan area, SE Baffin Bay. A multibeam survey was conducted in the area before the ROV dive. The benthic environment was video-recorded using a standard-definition color camera, at depths of ~900-950 m.

Sampling expeditions were conducted between September 2002 and 2004 in the southeastern Beaufort sea, onboard the CCGS Radisson, CCGS Amundsen, and CCGS Sir Wilfrid Laurier icebreakers. Additional sampling of newly-hatched Arctic cod was realized under the ice at two stations on a weekly basis from early February to the end of May 2004. The under-ice sampler consisted of a rectangular metal frame carrying side by side two 6-m long, 1-m2 mouth aperture, square-conical nets with 750 um mesh. This Double Square Net (DSN) was towed at 1 m s-1 between two holes in the ice separated by a distance of 300 m, using a Bombardier BR180® tractor. The DSN deployed under the ice in winter was deployed at least once at all the open-water stations in a double oblique tow down to a depth of 47 ± 8 m (mean ± standard deviation), at a ship speed of 1 m s-1 (2 knots) and a cable angle of 60º on the horizon. The datasets comprise larval and juvenile cod morphometric measurements, hatch dates, growth, and stomach content.
