Ocean Wise has introduced a new whale detection method using hydrophones to protect cetaceans in BC’s Salish Sea. These underwater microphones will alert commercial mariners in real time about the presence of orcas, allowing them to adjust their course, speed, or halt to minimize disturbances and potential collisions. Installed at the Boundary Pass Underwater Listening Station, these hydrophones are part of a system aimed at protecting the endangered Southern Resident killer whales by enhancing monitoring and mitigation measures against ship-related threats. This initiative is crucial as recent studies highlight the escalating risk of extinction for this species. The technology, which currently detects orca sounds within two kilometres, is planned to expand to include other whale species in the future.

Raincoast Conservation Foundation, in collaboration with a team of international scientists, released a new study on the potential to recover the critically endangered population of Southern Resident killer whales. This study updates an analysis undertaken 8 years ago, which estimated the population of 80 killer whales had a 24% chance of extinction within 100 years. The analysis showed that the action with the greatest leverage to recover SRKWs is their access to Chinook salmon.
