    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 sex lives of fish.

    David Gallo Underwater astonishments

    David Gallo shows jaw-dropping footage of amazing sea creatures, including a color-shifting cuttlefish, a perfectly camouflaged octopus, and a Times Square's worth of neon light displays from fish who live in the blackest depths of the ocean. This short talk celebrates the pioneering work of ocean explorers like Edith Widder and Roger Hanlon.

    Nicola Jones The dangers of a noisy ocean — and how we can quiet it down

    The ocean is a naturally noisy place full of singing whales, grunting fish, snapping shrimp, cracking ice, wind and rain. But human-made sounds — from ship engines to oil drilling — have become an acute threat to marine life, says science journalist Nicola Jones. Watch (and listen) as she discusses the strange things that happen to underwater creatures in the face of ocean noise pollution — and shares straightforward ways we can dial down the sound to see almost immediate impacts.

    Sylvia Earle My wish: Protect our oceans

    Legendary ocean researcher Sylvia Earle shares astonishing images of the ocean — and shocking stats about its rapid decline — as she makes her TED Prize wish: that we will join her in protecting the vital blue heart of the planet.

    Laura Robinson The secrets I find on the mysterious ocean floor

    Hundreds of meters below the surface of the ocean, Laura Robinson probes the steep slopes of massive undersea mountains. She's on the hunt for thousand-year-old corals that she can test in a nuclear reactor to discover how the ocean changes over time. By studying the history of the earth, Robinson hopes to find clues of what might happen in the future.

    Angelicque White What ocean microbes reveal about the changing climate

    When the ocean changes, the planet changes — and it all starts with microbes, says biological oceanographer Angelicque White. Backed by decades of data, White shares how scientists use these ancient microorganisms as a crucial barometer of ocean health — and how we might rejuvenate them as marine temperatures steadily rise.

    Ayana Elizabeth Johnson A love story for the coral reef crisis

    Over the course of hundreds of scuba dives, marine biologist Ayana Elizabeth Johnson fell in love — with a fish. In this ode to parrotfish, she shares five reasons why these creatures are simply amazing (from their ability to poop white sand to make colorful "wardrobe changes") and shows what's at stake — for us and them — as climate change threatens the future of coral reefs.

    Tierney Thys Swim with the giant sunfish

    Marine biologist Tierney Thys asks us to step into the water to visit the world of the Mola mola, or giant ocean sunfish. Basking, eating jellyfish and getting massages, this behemoth offers clues to life in the open sea.

    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 for it if you don't know it exists," he says. Join Peschak in a new, immersive TED Talk format as he shares his stunning work and his dream for a future of respectful coexistence with the ocean.

    Edith Widder Glowing life in an underwater world

    Some 80 to 90 percent of undersea creatures make light — and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and insight into the unseen depths (and brights) of the ocean.

    Robert Ballard The astonishing hidden world of the deep ocean

    Ocean explorer Robert Ballard takes us on a mindbending trip to hidden worlds underwater, where he and other researchers are finding unexpected life, resources, even new mountains. He makes a case for serious exploration and mapping. Google Ocean, anyone?

    Brian Skerry The ocean's glory — and horror

    Photographer Brian Skerry shoots life above and below the waves — as he puts it, both the horror and the magic of the ocean. Sharing amazing, intimate shots of undersea creatures, he shows how powerful images can help make change.

    John Delaney Wiring an interactive ocean

    Oceanographer John Delaney is leading the team that is building an underwater network of high-def cameras and sensors that will turn our ocean into a global interactive lab — sparking an explosion of rich data about the world below.

    Edith Widder How we found the giant squid

    Humankind has been looking for the giant squid (Architeuthis) since we first started taking pictures underwater. But the elusive deep-sea predator could never be caught on film. Oceanographer and inventor Edith Widder shares the key insight — and the teamwork — that helped to capture the squid on film for the first time.

    Jackie Savitz Save the oceans, feed the world!

    What's a marine biologist doing talking about world hunger? Well, says Jackie Savitz, fixing the world's oceans might just help to feed the planet's billion hungriest people. In an eye-opening talk, Savitz tells us what’s really going on in our global fisheries right now — it’s not good — and offers smart suggestions of how we can help them heal, while making more food for all.
