A dozen whales of different species and ages washed up on nearly 300 miles of Northern California coastline in the spring of 2015. While this is not a record, it's still alarming. Why did it happen? Bay Area scientists considered factors such as environmental changes, food distribution, shipping, ocean currents, and predator behavior. Meet staff from the California Academy of Sciences, Mission Science Workshop, and the Exploratorium, and explore evidence leading to and hypotheses about these events.
