Wiring the Abyss Leg 1: 19 June - 3 July 2018
During this 2-week expedition aboard the Canadian Coast Guard Vessel John P. Tully using Canadian Scientific Submersible Facility's ROV ROPOS, a team of 35 scientists, engineers, technicians and data specialists conducted around-the-clock operations to maintain, install and improve instrumentation on the offshore cabled observing networks at Barkley Canyon, Cascadia Basin, Endeavour and Clayoquot Slope.
Highlights of Leg 1 include an exciting new neutrino experiment at Cascadia Basin to determine whether this location can support a large-scale neutrino detector array in the future; expanded instrumentation at Endeavour, including new sensors and cameras to improve our understanding of this dynamic hydrothermal vent ecosystem; installation of the final earthquake early warning seafloor sensors at Cascadia Basin and Barkley Canyon; and reinstallation of the refurbished vertical profiling system at Barkley Canyon’s upper slope.
Join us for Leg 2 aboard EV Nautilus, 21 July - 4 August 2018.

Wiring the Abyss Leg 2: 7 – 26 June 2017
In June 2017, a team of 48 scientists, engineers, communicators, and crew aboard the exploration vessel Nautilus conducted 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—joined the expedition from its base in Victoria, British Columbia. Dual ship operations repaired 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 included: 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, Leg 1 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.
Wiring the Abyss, October 2016
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 included: 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 Explorer. Learn more about the expedition.
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.

Two expeditions took place simultaneously, in British Columbia's Salish Sea and the Canadian Arctic. The Salish Sea expedition sailed aboard CCGS John P. Tully, servicing VENUS observatory sites in the Strait of Georgia. The Arctic expedition serviced ONC's community observatory located in Cambridge Bay, Nunavut.

This expedition aboard the CCGS John P. Tully serviced the NEPTUNE observatory sites in the northeast Pacific.
Wiring the Abyss, March 2014
This expedition aboard CCGS John P. Tully serviced the VENUS observatory sites in the Salish Sea and Saanich Inlet.
Wiring the Abyss 2013
Five expeditions aboard CCGS John P. Tully, JOIDES Resolution, R/V Thompson, R/V Falkor and CCGS Vector suported observatory maintenance and scientific discovery in the Salish Sea and the northeast Pacific Ocean.
Wiring the Abyss 2012
Two expeditions, 27 May - 28 June, and 23 September - 10 October, took place off the west coast of Vancouver Island, B.C.
NEPTUNE Expeditions, 2009-2011
The NEPTUNE observatory's initial installations occurred between July and September 2009. Subsequent maintenance expeditions took place in May 2010, September - October 2010, July 2011 and September 2011.
