Scott Gass: How big is the ocean?

While the Earth's oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth's grandest geological features. Scott Gass reminds us of the influence humans have on the ocean and the influence it has on us. [Directe...

Ayana Elizabeth Johnson and Jennifer Jacquet: Will the ocean ever run out of fish?

When most people think of fishing, we imagine relaxing in a boat and patiently reeling in the day's catch. But modern industrial fishing -- the kind that stocks our grocery shelves -- looks more like warfare. Ayana Elizabeth Johnson and Jennifer Jacquet explain overfishing and its effects on ecosystems, food security, jobs, economies, and coasta...

Barbara Block: Tagging tuna in the deep ocean

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.

Jackson Browne: A song inspired by the ocean

Jackson Browne plays a song about being on the ocean ... or really, being anywhere among passionate friends. (He started writing this song aboard Mission Blue Voyage, a Sylvia Earle-inspired conference about saving the ocean.) "If I could be anywhere," he sings, "anywhere right now, I would be here."

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.

Jennifer Verduin: How do ocean currents work?

In 1992, a cargo ship carrying bath toys got caught in a storm. Shipping containers washed overboard, and the waves swept 28,000 rubber ducks and other toys into the North Pacific. But they didn't stick together -- the ducks have since washed up all over the world. How did this happen? Jennifer Verduin dives into the science of ocean currents. [...

David Katz: The surprising solution to ocean plastic

Can we solve the problem of ocean plastic pollution and end extreme poverty at the same time?

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.

Kate Slabosky: Can the ocean run out of oxygen?

For most of the year, the Gulf of Mexico is teeming with marine life, from tiny crustaceans to massive whales. But every summer, disaster strikes. Around May, animals begin to flee the area. And soon, creatures that can't swim or can't swim fast enough begin to suffocate and die off in massive numbers. What's going on? Kate Slabosky dives into t...

Augusto Carballido: There may be extraterrestrial life in our solar system

Deep in our solar system, a new era of exploration is unfolding. Beneath the thick ice of Europa; in the vapor plumes on Enceladus; and within the methane lakes of Titan, scientists are hunting for extraterrestrial life. These moons are 'ocean worlds'— they contain liquid oceans, which can support the formation of life. Does life exist on ocean ...

Ayana Elizabeth Johnson and Megan Davis: Underwater farms vs. climate change

For billions of people, seafood provides a significant source of protein and nutrition, but over half the seafood we eat isn't caught in the wild, it's grown through aquaculture. Farmed seafood is one of the fastest-growing food industries, but the farming methods echo the problems we've seen in industrial agriculture. Is there a way to sustaina...

Cella Wright: This sea creature breathes through its butt

Is it a fuzzy sock? An overripe banana? A moldy tube of toothpaste? In fact, it's a humble sea cucumber: a brainless, fleshy form surrounding a digestive tract, and bookended by a mouth and an anus. And while it might look odd, its daily toil paves the way for entire ecosystems to thrive. Cella Wright journeys to the bottom of the ocean to explo...

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 ...

Rob Dunbar: Discovering ancient climates in oceans and ice

Rob Dunbar hunts for data on our climate from 12,000 years ago, finding clues inside ancient seabeds and corals and inside ice sheets. His work is vital in setting baselines for fixing our current climate -- and in tracking the rise of deadly ocean acidification.
