2017 ROV video survey in a deep-water environment at Lancaster Sound (Qikiqtaaluk) aboard CCGS Amundsen

A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in July 2017 at Lancaster Sound, Nunavut. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at ~740 m. The ROV recorded transect data for approximately 1 km over a level muddy sand bottom with abundant Umbellula sea pens, Chondrocladia sp. carnivorous sponges, small Virgularia sp. sea pens, and common other sessile, sedentary and mobile epifauna and infauna including cerianthids, sea anemones, large Gorgonocephalus sp., and two common ophiuroid species, small holothurians and sea stars. The most common fish were eelpouts (Lycodes sp.), although several other types of fish were observed. Depth change over the 1 km transect was less than 10 m.
