 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.

 Media Release In 2017, Güralp employees were proud to present funds they had raised to Fir Tree Lodge, one of two nearby residential homes, run by Charity SeeAbility that provides support for people living with multiple disabilities and sight loss.
