Wiring the Abyss

Inshore Expedition 5 - 10 October

During the six-day expedition in the Strait of Georgia and Saanich Inlet, a team from Ocean Networks Canada (ONC) maintained, installed and improved instrumentation on the cabled ocean observing systems.

Highlights include: upgrades to the Delta Dynamics Platform at the mouth of the Fraser River that is helping understand underwater landslides; and upgrades to the Vancouver Fraser Port Authority's Underwater Listening Station, used to monitor underwater vessel noise.

This joint expedition was led by ONC and Natural Resources Canada using the Canadian Coast Guard Vessel John P. Tully and ITB's remotely operated vehicle Oceanic ExplorerLearn more about the expedition.

ONC completed its most challenging expedition in its 10-year history of collecting ocean data. This year’s two-month expedition off the west coast of Canada involved three ships, three remotely operated vehicles, and around-the-clock operations. The team of scientists, engineers and educators on board interacted via live-stream video during dives and engaging scientists and ocean lovers from around the world via the Twitter hashtag #ONCabyss.
