Ocean Networks Canada's #ONCabyss ocean expedition returns to the northeast Pacific Ocean off the west coast of Vancouver Island with a dual-ship operation aboard Canpac Marine Services' motor vessel (M/V) Canpac Valour from July 24–August 4, 2026, and the Canadian Coast Guard Ship (CCGS) John P. Tully from July 25–August 3, 2026.

In the first of two planned expedition legs, ONC will service the North East Pacific Time-series Undersea Networked Experiments (NEPTUNE) observatory off the west coast of Vancouver Island, and conduct ocean-based scientific research. Canpac Marine Services’ remotely operated vehicle (ROV) Mantis will serve as the hands and eyes of the operation, assisting with the recovery and deployment of scientific instruments and supporting science activities at sea—from the colourful ecosystems of Barkley Canyon to the anoxic waters of Saanich Inlet and more. Watch the operational live dives through ROV Mantis’ cameras from anywhere in the world.

Meanwhile, scientists and staff aboard the John P. Tully will collect seawater and sediment samples and deploy various instruments, including sediment traps.
