Kate Stafford: How human noise affects ocean habitats

Oceanographer Kate Stafford lowers us into the sonically rich depths of the Arctic Ocean, where ice groans, whales sing to communicate over vast distances -- and climate change and human noise threaten to alter the environment in ways we don't understand. Learn more about why this underwater soundscape matters and what we might do to protect it.

Thomas Peschak: Dive into an ocean photographer's world

Somersaulting manta rays, dashing dolphins, swarming schools of fish and munching sharks inhabit a world beneath the ocean's surface that few get a chance to see. Conservation photographer Thomas Peschak visits incredible seascapes around the world, and his photos reveal these hidden ecosystems. "You can't love something and become a champion fo...

Bhakti Sharma: What open water swimming taught me about resilience

Dive into the deep with open water swimmer Bhakti Sharma, as she shares what she learned about resilience during her personal journey from the scorching heat of Rajasthan, India to the bone-chilling waters of her record-breaking swim in Antarctica and her courageous crossing of the English Channel. "In the middle of the ocean, there is nowhere t...

Marah J. Hardt: Are we interrupting the kinky sex lives of fish?

The ocean plays host to a peculiar party of wild, marine sex life that's perhaps quirkier (and kinkier) than you can fathom. But is human behavior interrupting these raunchy reproductive acts? Take a deep dive with marine biologist Marah J. Hardt to discover what exactly goes down under the sea -- and why your own wellness depends on the healthy...

Patricia Villarrubia-Gómez: The problem with plastics -- and how they're changing the environment

Plastics are everywhere -- they're in our favorite electronic devices, they package our food and insulate our homes. Today, the total mass of plastic is twice the total mass of all living organisms on the planet, and it's starting to change the processes that allow the Earth's climate system to work. Plastic pollution researcher Patricia Villarr...

Kristina Gjerde: Making law on the high seas

Kristina Gjerde studies the law of the high seas -- the 64 percent of our ocean that isn't protected by any national law at all. Gorgeous photos show the hidden worlds that Gjerde and other lawyers are working to protect from trawling and trash-dumping, through smart policymaking and a healthy dose of PR.

Melissa Garren: The sea we've hardly seen

An average teaspoon of ocean water contains five million bacteria and fifty million viruses -- and yet we are just starting to discover how these "invisible engineers" control our ocean's chemistry. At TEDxMonterey, Melissa Garren sheds light on marine microbes that provide half the oxygen we breathe, maintain underwater ecosystems, and demonstr...

Karen Lloyd: This deep-sea mystery is changing our understanding of life

How deep into the Earth can we go and still find life? Marine microbiologist Karen Lloyd introduces us to deep-subsurface microbes: tiny organisms that live buried meters deep in ocean mud and have been on Earth since way before animals. Learn more about these mysterious microbes, which refuse to grow in the lab and seem to have a fundamentally ...

Stephen Palumbi: Hidden toxins in the fish we eat

What's link between the ocean's health and our health? Marine biologist Stephen Palumbi shows how toxins at the bottom of the ocean food chain find their way into our bodies -- and tells a shocking story of toxic contamination in the fish market, where consumers were being tricked into buying fish that's not only mislabeled but unsafe.

Hamish Jolly: A shark-deterrent wetsuit (and it's not what you think)

Hamish Jolly, an ocean swimmer in Australia, wanted a wetsuit that would deter a curious shark from mistaking him for a potential source of nourishment. (Which, statistically, is rare, but certainly a fate worth avoiding.) Working with a team of scientists, he and his friends came up with a fresh approach — not a shark cage, not a suit of chain-...

Maria Gallucci: The carbonless fuel that could change how we ship goods

Every day, tens of thousands of cargo ships, filled to the brim with goods, release heavy pollution into the air as they make their way across the ocean. In this eye-opening talk, reporter Maria Gallucci introduces a planet-friendly alternative that could fuel these globe-trotting vessels: green ammonia. Listen as she makes the case for this gam...

Fabien Cousteau: What I learned from spending 31 days underwater

In 1963, Jacques Cousteau lived for 30 days in an underwater laboratory positioned on the floor of the Red Sea, and set a world record in the process. This summer, his grandson Fabien Cousteau broke that record. Cousteau the younger lived for 31 days aboard the Aquarius, an underwater research laboratory nine miles off the coast of Florida. In a...

Kristen Marhaver: How we're growing baby corals to rebuild reefs

Kristen Marhaver studies corals, tiny creatures the size of a poppyseed that, over hundreds of slow years, create beautiful, life-sustaining ocean structures hundreds of miles long. As she admits, it's easy to get sad about the state of coral reefs; they're in the news lately because of how quickly they're bleaching, dying and turning to slime. ...

Claire Simeone: The lovable (and lethal) sea lion

Sunning themselves on rocks or waddling awkwardly across the beach, it's easy to think of sea lions more as sea house cats. But don't be fooled by their beachside behavior. Under the waves, sea lions are incredible endurance hunters, reaching speeds of 18 miles an hour and hunting for up to 30 hours at a time. Claire Simeone dives into what make...

Stephanie Sardelis: Why do whales sing?

Communicating underwater is challenging. Light and odors don't travel well, but sound moves about four times faster in water than in air — which means marine mammals often use sounds to communicate. The most famous of these underwater vocalizations is undoubtedly the whale song. Stephanie Sardelis decodes the evocative melodies composed by the w...

Carl Safina: What are animals thinking and feeling?

What's going on inside the brains of animals? Can we know what, or if, they're thinking and feeling? Carl Safina thinks we can. Using discoveries and anecdotes that span ecology, biology and behavioral science, he weaves together stories of whales, wolves, elephants and albatrosses to argue that just as we think, feel, use tools and express emot...

Mike Gil: The big-beaked, rock-munching fish that protect coral reefs

As the sun rises over a quiet coral reef, one animal breaks the morning silence. Named for its vibrant scales and beak-like teeth, the parrotfish devours a particularly crunchy breakfast: rocks. Why would any creature take bites out of the seafloor? Mike Gil explores how these quirky and flashy foragers play a key role in defending the essential...

Chris Burkard: The joy of surfing in ice-cold water

"Anything that is worth pursuing is going to require us to suffer, just a little bit," says surf photographer Chris Burkard, as he explains his obsession with the coldest, choppiest, most isolated beaches on earth. With jawdropping photos and stories of places few humans have ever seen -- much less surfed -- he draws us into his "personal crusad...

Cesar Harada: A novel idea for cleaning up oil spills

When TED Senior Fellow Cesar Harada heard about the devastating effects of the BP Oil spill in the Gulf of Mexico in 2010, he quit his dream job and moved to New Orleans to develop a more efficient way to soak up the oil. He designed a highly maneuverable, flexible boat capable of cleaning large tracts quickly. But rather than turn a profit, he ...

Rob Ulrich: How do oysters make pearls?

Despite their iridescent colors and smooth shapes, pearls are actually made of the exact same material as the craggy shell that surrounds them. Pearls, urchin spines, the shells of mussels, snails and clams, even coral— all these structures are made out of the same chemical compound: calcium carbonate. So how does this single ingredient form suc...

Zahra Biabani: The eco-creators helping the climate through social media

"Climate doom-ism," or a pessimistic outlook on the future of the planet, rivals climate denialism in holding up the fight against climate change, says activist Zahra Biabani. Illuminating how hope combats inaction, she takes us inside the world of eco-friendly content on TikTok -- and shows that we all have what it takes to make real change.

TED-Ed: How will AI change the world?

In the coming years, artificial intelligence is probably going to change your life— and likely the entire world. But people have a hard time agreeing on exactly how AI will affect our society.

Jill Seubert: How a miniaturized atomic clock could revolutionize space exploration

Ask any deep space navigator like Jill Seubert what makes steering a spacecraft difficult, and they'll tell you it's all about the timing; a split-second can decide a mission's success or failure. So what do you do when a spacecraft is bad at telling time? You get it a clock -- an atomic clock, to be precise. Let Seubert whisk you away with the ...

Carl Safina: The oil spill's unseen villains -- and victims

Even as the Deepwater Horizon tragedy unfolded, Carl Safina took the stage at TEDxOilSpill to share what the facts were known at the time. In a blood-boiling cross-examination, he suggests that the consequences will stretch far beyond the Gulf -- and many so-called solutions are making the situation worse.

James Cameron: Before Avatar ... a curious boy

James Cameron's big-budget (and even bigger-grossing) films create unreal worlds all their own. In this personal talk, he reveals his childhood fascination with the fantastic -- from reading science fiction to deep-sea diving -- and how it ultimately drove the success of his blockbuster hits "Aliens," "The Terminator," "Titanic" and "Avatar."

It's time for planetary-scale interventions to combat climate change -- and environmentalist Tim Flannery thinks seaweed can help.
