Wiring the Abyss

Wiring the Abyss Leg 2: 7 – 26 June

Starting 7 June, a team of 48 scientists, engineers, communicators, and crew aboard the exploration vessel Nautilus will conduct around-the-clock operations to maintain and expand instrumentation on Ocean Networks Canada’s cabled observing systems off Canada’s west coast.

During the first week Global Marine’s Cable Innovator, the world’s largest vessel of its kind—specifically designed for laying fibre optic cable—will join the expedition from its base in Victoria, British Columbia. Dual ship operations will repair fibre optic cable at 1200 metres depth to connect instruments and a borehole housing a Woods Hole Oceanographic Institution tiltmeter used to measure tectonic strain along the Cascadia Subduction Zone.
 
Other highlights include: deployment of additional earthquake early warning sensors; retrieval of ONC’s Internet-connected seafloor crawler Wally for a refit after five years researching gas hydrates at Barkley Canyon; seafloor mapping, and sample collection at all sites.

​Wiring the Abyss, April – May 2017

​During the ten-day expedition a team of 35 scientists, engineers, technicians and data specialists conducted around-the-clock operations to maintain, install and improve instrumentation on the cabled observing systems in: Saanich Inlet, Strait of Georgia, Endeavour, Clayoquot Slope, and Folger Passage.

​Highlights included: installation of a new instrument in the Strait of Georgia that will combine imaging sonar and video to improve our understanding of fish abundance, variations, and interactions; and preparations at Endeavour to significantly expand instrumentation, enhance maintainability, and allow us to better understand and monitor this remote marine protected area.

This joint expedition was led by ONC and Natural Resources Canada using the Canadian Coast Guard Vessel John P. Tully and Pelagic Research Services remotely operated vehicle Odysseus.​ Read more about the expedition.

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.

Wiring the Abyss, May – June 2016

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.

Wiring the Abyss, August – September 2015

ONC’s most complex maintenance expedition to date involved three ships and two remotely operated vehicles. E/V Nautilus, R/V Thompson and the cable ship Wave Venture visited eight observatory sites off the west coast of Canada. Meantime, far to the north, ONC’s third annual Arctic expedition deployed a new and expanded community observatory at Cambridge Bay, Nunavut.
