San Francisco has launched a new AI system aimed at reducing collisions between ships and whales in the Bay Area, one of the busiest waterways in North America, The Associated Press reported.
The network, known as WhaleSpotter, uses thermal cameras and AI technology to detect whale activity around the clock and alert mariners when whales are nearby. The effort comes amid rising gray whale deaths in the region each year.
According to marine researchers, at least 21 gray whales were found dead in the wider Bay Area last year, with many deaths linked to ship strikes. Scientists say the actual number is likely higher because many whale carcasses are never recovered.
Researchers say more whales are entering and remaining in San Francisco Bay due to changing ocean conditions connected to climate change. Warming temperatures and disruptions in Arctic food sources are believed to be affecting whale migration and feeding patterns, leaving many animals weakened during their long journeys and pushing them into the bay.
The new monitoring system combines AI detections with verification from professional marine mammal observers before warnings are shared with ferry operators, vessel traffic controllers and the public. Officials hope the technology will help ships slow down or adjust routes to avoid dangerous encounters with whales.
Another problem in the bay is the increased risk of whale entanglement in crab fishing gear. This has already led regulators to approve the use of ropeless crab fishing gear designed to reduce harm to whales while allowing fishermen to continue operating.
