A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in October 2015 in a site near Cape Dyer, Nunavut. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at a depth of ~750 m along a transect line 935 m long.

A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in October 2015 near Qikiqtarjuaq, Nunavut. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at a depth of ~620-680 m along a transect line 954m long.

Video surveys were conducted in July 2016 aboard CCGS Amundsen, using a Super Mohawk remotely operated vehicle (ROV) at Hatton Basin, Labrador (Canada). ROV dives occurred at two nearby sites (~28 km apart) in the Hatton Basin area (Dives 50 and 51). 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 556-633 m. ROV transects were conducted to collect video data, and samples of corals and sponges were also collected during dive 51. Box-cores were deployed at the two sites. Sea water was collected at several depth intervals from surface to near-bottom to characterize particulate organic matter and to determine calcium carbonate saturation.

Multibeam sonar data and accompanying acoustic sub-bottom profile data were collected using the multibeam echosounder aboard the scientific icebreaker CCGS Amundsen. Particular focus in 2017 and 2018 mapping was on deep water troughs with apparent mega-scale glacial lineations (MSGL) in the northwest portion of outer Frobisher bay, and in the deep fault-bounded southwest margin of outer Frobisher bay.

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.

A benthic survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in July 2017 at Disko Fan, SE Baffin Bay. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at a water depth of ~930 m. An experimental frame deployed in 2016 was recovered during this ROV dive, but no other collections took place at this site during this dive.

Two video surveys were conducted in July 2016 at Disko Fan (South East Baffin Bay, Nunavut, Canada) using a Super Mohawk remotely operated vehicle (ROV) aboard CCGS Amundsen. The benthic environment was video-recorded and photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at a depth range of 888-941 m. Sites suitable for the deployment of box-cores and piston-cores were identified from the videos during the first survey, samples of corals, sponges and a zoanthid were collected (N= 13), and a video transect was conducted. Sea water was collected at several depth intervals from surface to near-bottom to determine calcium carbonate saturation.

A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in October 2015 in Navy Board Inlet, Nunavut. The benthic environment was video-recorded and opportunistically photographed using a high-definition camera (1Cam Alpha, Sub C Imaging, 24.1 megapixels), at a depth of ~450 m along a transect line 480 m long.

A remotely operated vehicle (ROV) video survey was conducted at the NE Saglek Bank location, at a depth of ~1000 m in July 2018. The main objectives of this dive were to survey epifauna at 1000 m off of the bank and to collect corals, sponges, and other large epifauna from this depth zone. This dive was aborted due to twisting of cable wire and tension which caused video to fail repeatedly. Dive ended at 982 m.

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.
