Gray whales adapt to climate change by feeding in San Francisco Bay, prompting new ship alert system to prevent collisions
By
Lauren Sommer
Summary
Gray whales are increasingly entering San Francisco Bay to feed as climate change reduces their food supply in Arctic waters. This adaptation puts them in danger of ship strikes in one of the busiest waterways in the country. A new camera-based alert system is being developed to help ships and ferries detect and avoid whales, aiming to reduce deadly collisions while the whales adapt to changing ocean conditions.

· 3 pulledThe whales are making a pitstop on their long migrations from Mexico to Alaska, detouring under the Golden Gate bridge for a snack as climate change is shrinking their normal food supply in Arctic waters.
But as gray whales try to adapt to one human-caused impact by feeding in San Francisco Bay, it's putting them squarely in the path of another hazard: ships.
Gray whales used to be a rare sight in San Francisco Bay. Now, their spouts are appearing off Alcatraz Island in one of the busiest waterways in the country.
