Abstract: A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in July 2016 at South East Baffin Shelf (Labrador, Canada). The benthic environment was video-recorded and photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels) mounted on the ROV, at depths ranging between 492-500 m. The ROV dive was shortened early in the dive due to technical problems. Box-cores and an Agassiz trawl were deployed after the ROV dives. Sea water was collected at several depth intervals from surface to near-bottom to determine calcium carbonate saturation. The main purpose of this survey was to collect video data to allow an assessment of invertebrate (e.g. corals and sponges) and fish biodiversity within the South East Baffin Shelf (Labrador, Canada), from where there are reports of high sponge bycatch. Sampling of deep-water corals and sponges was another objective of the survey at this site.
