Barbara Block at TED: Tagging tuna in the deep ocean

Marine biologist, Barbara Block (a MacArthur “genius” grant winner), part of the Tagging of Pacific Predators (TOPP) team operating out of Stanford’s Hopkins Marine station delivered a talk to TED in April this year. Her study is attempting to combine physical tracking data of bluefin tuna with physiological and genetic analysis of them and through this to develop population and ecological models to help us understand these fishes’ roles in the ocean ecosystem. The ultimate aim is to learn to better manage these important food fish.
