Peter Tyack: The intriguing sound of marine mammals |
Peter Tyack, a senior scientist in biology at the Woods Hole Oceanographic Institution, has always been intrigued by animal behavior. A class at Woods Hole while still in college led Peter down his current path of research on acoustic communication and social behavior in marine mammals.
He has studied the songs of humpback whales, the signature whistles of dolphins and the echolocation pulses of sperm whales and dolphins. Tyack has pioneered several new methods to sample the behavior of these mammals, including the development of sound-and-orientation recording tags.
As a result of his work recording the sounds of whales, Tyack is concerned that the ubiquitous noises from human activity in the ocean -- sonar, oil rigs, motorboats, shipping traffic -- are disturbing marine mammals.

Dan Barber: Sustainable Fish II & Palumbi's "Mercury Trail"!
Dan Barber: How I fell in love with a fish
Chef Dan Barber squares off with a dilemma facing many chefs today: how to keep fish on the menu. With impeccable research and deadpan humor, he chronicles his pursuit of a sustainable fish he could love, and the foodie's honeymoon he's enjoyed since discovering an outrageously delicious fish raised using a revolutionary farming method in Spain.
Stephen Palumbi: Following the Mercury Trail:
There's a tight and surprising link between the ocean's health and ours, says marine biologist Stephen Palumbi. He shows how toxins at the bottom of the ocean food chain find their way into our bodies, with a shocking story of toxic contamination from a Japanese fish market. His work points a way forward for saving the oceans' health -- and humanity's.
Stephen Palumbi teaches and does research in evolution and marine biology at Stanford University, and has long been fascinated by how quickly the world around us changes. His work on the genetics of marine organisms tries to focus on basic evolutionary questions but also on practical solutions to questions about how to preserve and protect the diverse life in the sea. DNA data on the genetics of marine populations like corals helps in the design and implementation of marine protected areas for conservation and fisheries enhancement. A second focus is on the use of molecular genetic techniques for the elucidation of past population sizes and dynamics of baleen whales, with the notion of recreating a better sense of the ecology of the virgin ocean.
Palumbi has lectured extensively on human-induced evolutionary change, has used genetic detective work to identify whales for sale in retail markets, and is working on new methods to help design marine parks for conservation. His first book for non-scientists, The Evolution Explosion, documents the impact of humans on evolution. The next one, due out by Island Press in 2010, is an unusual environmental success story called Monterey Bay Reborn. He also helped write and research and appears in the BBC series The Future Is Wild and the History Channel's World Without People. Other recent films appearances include The End of the Line and an upcoming Canadian Broadcasting series One Ocean.
Palumbi's other passion: microdocumentaries. His Short Attention Span Science Theater site received a million hits last year. And his band Sustainable Soul has several songs out, including "Crab Love" and "The Last Fish Left."

Reviving New York's Rivers with Oysters! & Sustainable Seafood!
Reviving New York's rivers -- with oysters! Video on TED.com
Architect Kate Orff sees the oyster as an agent of urban change. Bundled into beds and sunk into city rivers, oysters slurp up pollution and make legendarily dirty waters clean -- thus driving even more innovation in "oyster-tecture." Orff shares her vision for an urban landscape that links nature and humanity for mutual benefit.
Barton Seaver: Sustainable Seafood? Let's Get Smart:
Chef Barton Seaver presents a modern dilemma: Seafood is one of our healthier protein options, but overfishing is desperately harming our oceans. He suggests a simple way to keep fish on the dinner table that includes every mom's favorite adage -- "Eat your vegetables!"
