Southern Resident killer whales, an endangered population that depends on salmon, face ship noise that disrupts their hunting and communication, as well as the threat of collisions. A 2024 study found that a one-decibel increase in noise reduces the likelihood of females pursuing prey by 58% and lowers their chances of a successful hunt by 12.5%. A voluntary program in Washington state that encourages vessels to slow down reduced underwater noise by up to 50%, with 73% of vessels taking part. The Quiet Sound initiative, SMRU Consulting and Microsoft are testing an AI-powered buoy to detect whale calls in Haro Strait, paving the way for improved tracking and alerts to vessels about the whales’ locations.
