‘Come with us’: Expedition explores new ocean floor developments at Juan de Fuca Ridge

By Alexandra Mehl, Ha-Shilth-Sa, Local Journalism Initiative Reporter

On Wednesday, June 6, Ocean Networks Canada (ONC) and Ocean Exploration Trust departed from Sydney, BC on their annual 21-day expedition, where the team could be the first to lay eyes on a newly formed ocean floor.

In early March a series of more than 200 earthquakes per hour, referred to as an earthquake swarm, was detected at a depth of five kilometers and roughly 240 kilometers offshore of Vancouver Island at the Juan de Fuca Ridge site. The earthquakes reached a magnitude of 4.1.

“The spike of earthquake activity at the Endeavour segment of the Juan de Fuca Ridge could be a sign of an ‘impending magmatic rupture’,” reads a statement from ONC, quoting marine seismology PhD candidate Zoe Krauss. “A natural phenomena that can form new ocean floor.”

Rays of hope for kelp and climate in south Salish Sea

Editor’s note: Bull kelp grows from Alaska’s Aleutian Islands to Santa Barbara County in California. There is a lot of it around Vancouver Island, and in the waters off both Cortes and Quadra Islands.

It’s not all doom and gloom for the rich underwater kelp forests in the southern Salish Sea struggling to weather increasingly warm oceans. 

Some pockets of bull kelp vital for sea life off southern Vancouver Island and B.C.’s Gulf Islands are proving to be resilient to rising sea temperatures and marine heat waves, a new University of Victoria study has found.

No spill response can eliminate risk to marine life in the Strait of Juan de Fuca

By Sidney Coles, Capital Daily, Local Journalism Initiative Reporter

Last week, Capital Daily reported that the new 74.5-metre (244-foot) Western Marine Response Corporation (WMRC) vessel named the K.J. Gardner will be docked in Beecher Bay early in the new year. The ship is purpose-built to patrol the BC coastline and respond in the event of an oil spill.

This additional response resource is being deployed in anticipation of the 34+ tankers per month (450 per year) that will soon come out of Burnaby’s Westridge Marine Terminal laden with oil from the TMX pipeline before making their way through the San Juan Islands and the Strait of Juan de Fuca.

No European Green Crabs in the Discovery Islands, yet

The Friends of Cortes Island (FOCI) have not found any European Green Crabs in Manson’s lagoon, and so far there’ve been no sightings north of Nanaimo.  

“We haven’t found any, that’s really good news, but we’ve been very pleased to partner with the Department of Fisheries and Oceans (DFO).  Hopefully, if we ever find them, we’ll be able to trap them out and stop them from harming the valuable habitat here,” explained Helen Hall, Executive Director of FOCI.

Monitoring Dungeness Crab larvae in Cortes Bay

Last April, Cortes Island became part of an international monitoring project for Dungeness crab larvae. There were 20 light trap stations in the Salish Sea and 17 in the Puget Sound. Three of these traps were within our  listening area. Surge Narrows School had a trap on Read Island. The Hakai Institute and Quadra Island community had another on Quadra Island. Kate Maddigan and Mike Moore coordinated volunteers looking after the Friends of Cortes Island (FOCI) trap in Cortes Bay.
