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.

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.

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 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.

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.

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 (Dive 52) using a Super Mohawk remotely operated vehicle (ROV) was conducted in July 2016 at Saglek Bank (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, surveying depths ranging between 363-473 m. At this site, a video transect was prioritized over sampling, but 1 coral sample and 2 sponges were collected. At this location, three box-cores were deployed at two nearby sites, from which only a small sample was retained. Sea water was collected at several depth intervals from surface to near-bottom to determine calcium carbonate saturation.

The webcam was installed on the navigation deck of CCGS Amundsen on the port side (see http://www.amundsen.ulaval.ca/index.php?url=11511&sub=1). Its field of view nearly match with that of microwave radiometer. Thus, both of the instruments look at the same area on the ground. The webcam is set to acquire JPEG images every 5 seconds or it can be set according to the requirement by the user. A sodium lamp has be lighted on the port side to get the pictures during the night time.

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.
