Hushed seas: monitoring underwater noise during COVID-19

A new study using Ocean Networks Canada’s (ONC) Pacific Ocean hydrophone data reveals a significant reduction in underwater noise during the COVID-19 shutdown, which may be good news for endangered southern resident killer whales.

When the coronavirus put the world on lockdown in March 2020, David Barclay, assistant professor at Dalhousie University’s Department of Oceanography, recognized a unique opportunity to monitor changes in underwater noise. Without leaving his home in Atlantic Canada, Barclay was able to remotely study the Pacific Ocean soundscape using...

New Online Learning Resource Listens to Orcas

As students in BC and across Canada return to school, Ocean Networks Canada (ONC) and Open School BC (OSBC) are delighted to announce the release of Shouting Whales, a new marine science educational resource for teachers and educators, that is available free of charge. 

Aimed at middle school students from grades six to eight, Shouting Whales is a unique resource that brings together science, problem-based learning, multimedia, and advocacy for an in-depth exploration of the oceanic soundscape.

Exploring noise pollution beneath the surface of the sea

In particular, students are asked to think about the ocean from the perspective of the orca whale, an...

Transient Killer Whale Sounds Recorded at Strait of Georgia

Studying marine mammals vocalizations in the ocean has been an ongoing Ocean Networks Canada project. A number of hydrophones have been installed and tested on the VENUS observatory, both in Saanich Inlet and the Strait of Georgia. As identified by the research community, the main area of interest in this research is the Strait of Georgia. A busy marine traffic lane, home to the resident Killer Whales, the Strait also provides a hunting ground for transient Killer Whales.

Today we wanted to feature sounds captured on the deepest (300m) Central Node hydrophone system in the...
