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 Ocean Networks Canada’s cabled observing networks, with the support of Pelagic Research Services ROV Odysseus.

The Canadian Coast Guard Ship John P. Tully team positions ROV Odysseus before a dive in the Strait of Georgia.

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.
