(2019) 2017 ROV video survey in a deep-water environment at Lancaster Sound (Qikiqtaaluk) aboard CCGS Amundsen. Waterloo, Canada: Canadian Cryospheric Information Network (CCIN). Unpublished data A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in July 2017 at Lancaster Sound, Nunavut.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. The main purpose of the ROV dive in Lancaster Sound was to investigate biogenic habitats of the tall Arctic sea pen Umbellula encrinus, as well as other benthic invertebrate and fish biodiversity in the area.
