#ONCabyss Expedition: 5-17 September 2020

During this 2-week expedition aboard Exploration Vessel Nautilus a reduced team of 7 ONC staff will conduct around-the-clock operations to maintain, install and improve infrastructure and instrumentation on ONC’s cabled observing networks in the northeast Pacific. In addition to annual maintenance and research activities, the purpose of this expedition is to prepare for new infrastructure deployments planned to take place on board Canadian Coast Guard Ship John P. Tully, 21 September - 6 October.

This expedition will operate under COVID-19 safety protocols, following the measures provided by the US Center for Disease Control, World Health Organization, University National Oceanography Laboratory System and the British Columbia Centre for Disease Control and the Public Health Agency of Canada to prevent the risk of infection onboard.


#ONCabyss Expedition: 1-14 June 2020

During this 2-week expedition aboard the Canadian Coast Guard Vessel John P. Tully a reduced team of 8 ONC staff and ROV pilots conducted operations to maintain, install and improve infrastructure and instrumentation on ONC’s cabled observing networks with the support of Pelagic Research Services’ remotely operated vehicle Odysseus. The purpose of this expedition was to prepare for scheduled operations involving E/V Nautilus and cable ship Cable Innovator later in 2020.

Due to COVID-19, this expedition operated under Canadian Coast Guard COVID-19 safety protocols, following the advice provided by the BC Centre for Disease Control and the Public Health Agency of Canada to prevent the risk of infection onboard.


Wiring the Abyss, Inshore/Offshore Maintenance with NRCAN: 01 - 13 March 2020

During this 2-week expedition aboard the Canadian Coast Guard Vessel John P. Tully a team of 18 scientists, engineers, technicians and data specialists will conduct operations to maintain, install and improve infrastructure and instrumentation on ONC’s cabled observing networks.

Highlights include:

  • Recover and redeploy Saanich instrument platform
  • Deploy AMAR Hydrophone Array
  • Deploy new SOG East Instrument Platform
  • Locate & Redeploy DDL Instrument Platform
  • Deploy new Folger Deep Instrument Platform

Wiring the Abyss: 10 - 25 September 2019

During this 2-week expedition aboard the Canadian Coast Guard Vessel John P. Tully a team of 17 scientists, engineers, technicians and data specialists will conduct operations to maintain, install and improve infrastructure and instrumentation on ONC’s cabled observing networks, with the support of Pelagic Research Services ROV Odysseus.

Highlights include:

  • Deploying a new Delta Dynamics Platform in the Strait of Georgia, at the mouth of the Fraser River. Two improved Natural Resources Canada instruments will help understand and monitor underwater slope failures and landslides. Read about the tumbling delta dynamics laboratory platform and how it turned into a scientific highlight.
  • Installing and reconnecting instruments at Barkley Canyon including new video and acoustic cameras for a fish sounds and behaviour experiment.
  • Expanded instrumentation at Endeavour hydrothermal vents, including new seismometers and cameras to improve our understanding of the dynamic spreading ocean ridge ecosystem at Canada’s first marine protected area.
  • Improvements to the tsunami detection array at Cascadia Basin.
  • New deep-sea moorings will be deployed to measure ocean currents that flow along the Juan de Fuca volcanic ridge.

Wiring the Abyss, Offshore Maintenance: 7 - 21 May 2019​

During this 2-week expedition aboard the Canadian Coast Guard Vessel John P. Tully using Pelagic Research Services ROV Odysseus, a team of 17 scientists, engineers, technicians and data specialists will conduct operations to maintain, install and improve infrastructure and instrumentation on Ocean Networks Canada’s cabled observing networks in the Salish Sea, and deep sea offshore sites at Barkley Canyon, Endeavour, Cascadia Basin, and Clayoquot Slope.

Highlights of Leg 1 include:

  • Deploying a mooring at Saanich Inlet sill to further understand this unique natural low oxygen zone.
  • Instrumentation at Endeavour hydrothermal vents will see significant expansion, including new sensors and cameras to improve our understanding of the dynamic ecosystem that is Canada’s first marine protected area.
  • Improvements will be made to the tsunami detection array at Cascadia Basin.
  • New deep sea moorings will be deployed to measure ocean currents that flow along the Juan de Fuca volcanic ridge.

Wiring the Abyss, Inshore Maintenance: 28 September - 9 October 2018

During the twelve-day expedition a team of 35 scientists, engineers, technicians and data specialists will conduct around-the-clock operations to maintain, install and improve instrumentation on the cabled observing systems in Saanich Inlet and Strait of Georgia.

Highlights include: in the Strait of Georgia, at the mouth of the Fraser River, two improved NRCan instruments to help understand and monitor underwater slope failures and landslides will be installed including: a new and improved Delta Dynamics Platform and a seismic liquefaction in-situ penetrometer used to measure pressure at the seafloor and at two points below the seafloor in real-time. In the Saanich Inlet the buoy profiler will be reconfigured and brought back on line.

This joint expedition will be led by ONC and Natural Resources Canada using the Canadian Coast Guard Ship John P. Tully and the Island Tug and Barge Oceanic Explorer remotely operated vehicle.


Wiring the Abyss Leg 2: 23 July – 3 August 2018

In July 2018, 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.

Highlights 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, Barkley Canyon, and Clayoquot Slope; and reinstallation of the refurbished vertical profiling system at Barkley Canyon’s upper slope.
