While the eruptions of the volcanoes along the Mid-Atlantic Ridge usually don't trouble us, their birth was once responsible for ripping a supercontinent apart and creating the Atlantic Ocean that we know today.

Unlike in fiction, giant whales do not emerge fully-formed from the ocean deep. So, where did Livyatan melvillei come from? How did such a large predator live? And what caused the titan to die out? The answer may lie in an appetite so...

This is the hundred-year tale of how an unlikely bunch of bottom-dwelling marine critters helped reveal that ocean basins are basically reincarnated every few hundred million years.

This is the story of how our planet rescued itself from extreme conditions in the Cretaceous Period, at the cost of essentially suffocating the oceans for half-a-million years.

What graptolites tell us is a story of incredible changes in the ocean, of periods where the oceans became poisonous and suffocating before eventually clearing up again. They unlock extinctions and recoveries that scientists didn't see....

Today, the Great Salt Lake of Utah has multiples of the ocean's salt concentration. But it didn't used to be so salty. In fact, it used to be Lake Bonneville. And we know its story thanks to microscopic diatoms and Dr. Ruth Patrick....

There's a complex, mysterious current running throughout the Atlantic Ocean, and it's in trouble. But to help save it, researchers need to understand it, and finding ways to study it has been a challenge. But it turns out that the secret...

Adding sand to beaches sounds like it's an oxymoronic thing to do, but it's totally a thing. And there's some major benefits, like protecting our coastlines from storms and conserving ecosystems. But there are also some major drawbacks,...

The deepest hole we've ever been able to dig is just 0.2 percent of the way to the center of the Earth. What would we encounter if we could drill all the way? Correction: We mislabeled these! These are ammonite fossils, not trilobite...

This October, the launch window opens for NASA's Europa Clipper mission. When it arrives in the Jovian system, this spacecraft will probe the icy moon...and its ocean buried kilometers beneath the surface...for the ingredients of life as...

We've all heard about microplastics, but where do they come from? And what can we do about ocean plastics? We'll follow a single water bottle on its journey to the Great Pacific Garbage Patch and beyond. Hosted by: Stefan Chin

Polymetallic nodules, found at the bottom of the Pacific Ocean's Clarion-Clipperton Zone, have enough metals to secure the future of green energy. But is it worth the cost? Hosted by: Savannah Geary (they/them)

Coral reefs are fighting for their very survival these days, and scientists are looking for ways to help—including testing underwater AC systems, and 3D printing what one might describe as artificial coral cyborgs. Hosted by: Savannah...

Dams are great for humans, providing hydroelectricity and flood control. They're also horrible for the rivers they block. Here are three success stories of ecosystems that bounced back after a dam was removed. Hosted by: Savannah Geary...

We are not drowning. We are fighting, says storyteller Fenton Lutunatabua, echoing the mantra of the climate activists he works with across the Pacific. He shares stories of the people and communities at the front lines of the climate...

Coral reefs are the most biodiverse ecosystem on the planet and the lifeblood of a thriving ocean. Yet without action, 90 percent of coral reefs could die by 2050. Fortunately, reef guardian Theresa Fyffe has a plan. Learn how her team...

In this video Paul Andersen shows how increasing ocean temperatures causes coral polyps to release their symbiotic algae. This process of coral bleaching decreases the availability of energy for the coral and may eventually lead to coral...

What happens when the fish that sustain a community start disappearing? Environmental activist Lamin Jassey shares how industrial fish meal factories are devastating local waters, livelihoods and health in The Gambia — and how...

Mount Teide is one of the world’s largest active volcanoes, and there may be a way to use the basalt rock inside it to save humanity. Obviously, destroying an ancient volcano would cause catastrophic and unpredictable ecological fallout....

Humans have been transforming seawater into potable freshwater for millennia. Today, billions of people can’t access clean drinking water, and 87 different countries are projected to be “water-scarce” by 2050. So, how can we use seawater...

It seems wild that some animals basically trade in their bodies for new ones during their lifetime, but it's actually really common – and it makes a lot of sense.

You might think the most dangerous thing that can happen at a beach is a shark attack, or that the scariest thing might be a tsunami - but instead, rip currents kill more beachgoers than all other causes combined.

Life in Antarctica's ocean has followed a completely different evolutionary path from other ocean life because of how cold and isolated the ocean is.

When a ship sinks, lots of factors, like the ship’s materials, the water quality, and the depth of the seafloor all play a role in determining how long the ship will last down there - as a result, the Titanic will be gone in fifty years,...
