Explore the fascinating world of tuna tracking in this 21-minute TED Talk by marine biologist Barbara Block. Discover how cutting-edge tracking tags with transponders are revolutionizing our understanding of these fast, far-ranging ocean predators. Learn about the challenges of studying tuna in the vast open ocean, the steep decline of bluefin populations, and the importance of identifying feeding and breeding areas. Gain insights into the engineering challenges of tagging large, fast-moving marine animals like tuna, mako sharks, and blue whales. Examine how the data collected from 25,000 positions of 455 tracked Atlantic bluefin tuna is being used to develop overlap models and improve management strategies. Understand the potential of real-time monitoring and public engagement in protecting iconic ocean species, including debunking internet myths about white sharks. Conclude with a message of hope for the future of marine conservation through innovative technology and increased biological logging capacity across oceans.
