AI Could Quiet Ship Noise
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.
