SubC Imaging’s 1Cam Used as ROV Inspection Camera
After completing a 16-day subsea expedition for the ongoing “Wiring the Abyss” project where SubC Imaging’s subsea cameras aid in maintaining and improving infrastructure and instrumentation on Ocean Networks Canada’s cabled observing networks, Pelagic Research Services will be teaming up with Ocean Networks Canada once again.

For the upcoming 14-day expedition scheduled for September 2020, Pelagic Research Services will be an essential part of the ONC team by providing ROV services to ONC as they continue the work on NEPTUNE, the largest cabled ocean observatory. The cabled ocean observatories that make up NEPTUNE span a wide range of ocean environments, from wave-dominated coast, to gas-venting seafloor areas, to deep water hydrothermal vents. The water depths for this project will be greater than 2200 meters at times and include low-visibility environments off the Fraser River.
No stranger to using SubC Imaging’s subsea cameras for their inspections, PRS’ deep-sea ROV Odysseus will once again be equipped with a SubC video camera. Mobilizing the ROV on the Canadian Coast Guard ship John P. Tully, SubC Imaging’s 1Cam will be the primary inspection camera unit.
SubC has been providing cameras and accessories to ONC’s ocean observatories ever since the University of Victoria (UVIC) first started using SubC’s equipment for their research in 2012.
A recent study from the largest cabled ocean observatory in 2018 revealed seasonal overwintering of Neocalanus spp. in Barkley Canyon, one of the many observatories that make up NEPTUNE. A total of 33,486 still images were extracted from 1674 × 5-min segment videos, captured at two-hour intervals, to estimate Neocalanus spp. densities near the seafloor.
