San Francisco: This week authorities and maritime operators launched WhaleSpotter, an AI-powered detection network in San Francisco Bay that scans for whale blows and heat signatures up to two nautical miles and sends real-time alerts to ferries, cargo ships and tankers so crews can slow or reroute. Operators including San Francisco Bay Ferry say the system will allow adjustments well before vessels approach whales and will collect location data to identify seasonal hotspots; the deployment follows reports last year of 21 gray whale carcasses in the wider Bay Area, with at least 40% of deaths linked to ship strikes.

Timeline of Events
- Over the past year, observers and The Marine Mammal Center documented an increase in gray whale deaths in the Bay Area.
- The Marine Mammal Center reported 21 gray whale carcasses last year, the highest in 25 years; at least 40% were attributed to ship strikes.
- Concern among operators and conservationists led to testing and deployment plans for detection technologies.
- This week, WhaleSpotter was launched in San Francisco Bay to scan 24/7 and provide mariner alerts within two nautical miles.
- Operators will use detection data to adjust routes during whale season and monitor for future mortality trends.
News Intelligence
- WhaleSpotter's launch could mean safer waters for whales and smoother sailing for you. If you're a Bay Area resident or visitor, expect fewer disruptions to ferry services during whale season. And if you're a nature lover, know that your local waters are becoming a safer place for these majestic creatures.

Maritime operators, ferry services, conservation groups and marine mammals benefit from real-time whale detection, which provides data to adjust routes and reduce ship strikes while improving situational awareness for crews operating in San Francisco Bay.
Gray whales and other coastal marine life have suffered increased mortality from ship strikes in the Bay Area, and local shipping operations may face operational impacts such as slower transits or route changes to mitigate collisions.
