Gray Whales Entering San Francisco Bay Amid Food Shifts, Ship Strike Deaths
Gray whales are entering San Francisco Bay in greater numbers to search for food, a shift linked to reduced food availability in Arctic waters. Several have died from collisions with ships, prompting new efforts to reduce ship strikes.
Gray whales are appearing in San Francisco Bay, a change from their historically rare presence. These whales are making detours in their migration from Mexico to Alaska, entering the bay to search for food. Climate change is reducing food availability in Arctic waters for gray whales. Whale spouts are now being observed off Alcatraz Island. Seven gray whales have died in San Francisco Bay this year, and 21 died in the greater Bay Area last year, according to CBS News. Many of the dead gray whales in the Bay Area died from ship strikes. Roughly 40% of gray whale deaths in the area are attributed to collisions with ships, according to CBS News. Scientists are using AI to help reduce whale-ship collisions, according to CBS News. A new camera system could assist ships and ferries in avoiding whales, according to NPR. The first major step in addressing whale ship strikes officially launched this week, according to CBS News. Dr. Douglas McCauley said new data and community involvement are enabling solutions to whale ship strikes, according to CBS News.
