EmailApril 2010 - Stanford's Barbara Block speaks in the Galapagos as part of TED's Mission Blue Voyage to protect the ocean.
About this talk
Tuna are ocean athletes -- fast, far-ranging predators whose habits we're just beginning to understand. Marine biologist Barbara Block fits tuna with tracking tags (complete with transponders) that record unprecedented amounts of data about these gorgeous, threatened fish and the ocean habitats they move through.
About Barbara Block
Barbara Block studies how tuna, billfish and sharks move around (and stay warm) in the open ocean. Knowing how these large predators travel through pelagic waters will help us understand their role in the wider ocean ecosystem.
