 Media Release Ocean Networks Canada (ONC), a University of Victoria initiative, successfully deployed a string of three cabled Güralp Maris ocean bottom seismometer (OBS) as part of the first leg of their 2018 ‘Wiring the Abyss’ expedition aboard Canadian Coast Guard Ship the 'John P. Tully'. The deployment formed part of a two week project to install and improve instrumentation on the offshore cabled observing networks at Barkley Canyon, Cascadia Basin, Endeavour and Clayoquot Slope in the Northeast Pacific Ocean. The Güralp OBS were deployed at Endeavour, the northern segment of the Juan de Fuca Ridge, a divergent boundary between the Pacific and Juan de Fuca tectonic plates. The instruments were positioned at a depth of approximately 2200 m adjacent to hydrothermal vents that have formed along the ridge, and were lifted into place using the Canadian Scientific Submersible Facility’s remotely operated vehicle for ocean science—ROPOS. One of benefits of…
