Coral samples were collected in Pond Inlet and Lancaster Sound in Baffin Bay using the CCGS Amundsen’s remotely operated vehicle (ROV). Samples from Agassiz trawl and box-core deployments were also kept as part of this study (11 stations). Samples were collected between 253 and 856 m. Specimens were subsampled aboard and frozen for determination of their carbon and nitrogen stable isotopic composition, as well as for lipids and fatty acids composition, as part of a study focusing on the trophic ecology of cold-water corals. Carbon and Nitrogen stable isotope analysis as well as lipids/fatty acids analysis were performed on tissue samples of soft corals at the Stable Isotopes Laboratory and Lipids Laboratory, Memorial University, respectively.

A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in July 2017 at Pond Inlet, Nunavut. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), starting at a depth of 850 m. Samples of corals and sponges were collected, mainly for studies of biodiversity and geochemistry. Soft corals, sponges, and sea anemones were conspicuous at this site.
