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 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.

A video-survey using a Super Mohawk remotely operated vehicle (ROV) was conducted in October 2015 at Inner Frobisher Bay, 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 ~59-139 m along a transect line 1.2 km 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.

In July 2014 and October 2015 a Super Mohawk (SuMo) remotely operated vehicle (ROV) aboard the CCGS Amundsen was used to video-survey a deep-water environment at Scott Inlet. In 2014, a video-transect ~2.7 km long was followed across depths of 475-650 m. Videos and photographs were obtained using a high-definition camera, and specimens of invertebrates (sponges) were collected using the ROV. In 2015, no transect was followed and the main objective was to sample carnivorous sponges using a sampling platform.

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 remotely operated vehicle (ROV) video survey was conducted at the Saglek Bank location, at a depth of ~750 m in July 2018. The main objectives of this dive were to video-survey coral and sponge fauna on ridge at 750 m depth, and to collect coral and sponge samples. Bottom type was mainly sandy and gravel, with boulders in some parts of the transect. Corals include the solitary scleractinian Flabellum sp., soft corals (Nephtheidae), mushroom soft corals (probably Anthomastus sp.), sea pens Anthoptilum (erect and also lying on sea floor) and Halipteris finmarchica on sandy gravel bottom. Dead sea pen skeletons were also observed. Sponges include Asconema sp., Geodia sp., encrusting blue sponges (Hymedesmia sp.), and some unidentified fan-shape sponges. Among fish, we observed redfish (Sebastes spp.), small grenadiers (Family Macrouridae), and small (likely juvenile) skates (Family Rajidae). Other invertebrates include unidentified squat lobsters, sea anemones, and crabs.

Two remotely operated vehicle (ROV) video surveys were conducted at the SW Greenland location, at depths of ~700-950 m in August 2018. The primary purpose of the ROV dives at this location was to video survey the area study the distribution, geology, and species associations to the reef-forming cold-water coral Lophelia pertusa. Another objective of these dives was to survey the area to identify a suitable location for piston coring. Lophelia pertusa coral colonies were observed on steep bedrock surfaces between 950 and 750 m water depth. Other corals observed at this site include Primnoa resedaeformis, Paragorgia arborea, soft corals, and sponges Asconema spp, Geodia spp., among others. No sampling took place at this location due to ROV issues.

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.
