Dr. Forrester explains how all animals rely on producers, or plants, to provide a foundation for food chains and food webs.

Deep in the ocean, fluffy bits of organic matter fall like snow. But this marine snow isn’t just pretty; it’s an essential part of our ocean food webs and our global climate!

Enric Sala shares glorious images -- and surprising insights and data -- from some of the most pristine areas of the ocean. He shows how we can restore more of our oceans to this healthy, balanced state, and the powerful ecological and...

In this video Paul Andersen explains how ecosystems function. He begins with a description of how life on the planet is ordered from large to small in biomes, ecosystems, communities, population, and individuals. He describes the major...

PACE's advanced technologies will provide unprecedented insight into Earth's ocean and atmosphere, which impact our everyday lives by regulating climate and making our planet habitable. Our oceans teem with life,...

"The Ocean's Green Machines" is Episode 3 in the six-part series "Tides of Change", exploring amazing NASA ocean science to celebrate Earth Science Week 2009.



One tiny marine plant makes life on Earth possible: phytoplankton....

Jellyfish aren't the most nutritious animals in the ocean. Yet sea turtles and many other organisms get their nutrition from almost nothing else. Here's why they don't totally starve to death.

Carbon is fundamental to life on Earth. And it goes through a complex cycle, from up in the atmosphere, to the depths of the ocean. But down there, the carbon trail gets harder to follow. Or at least, it was that way until this little...

Thanks to humans, old school apex predators are struggling to hold onto their perch at the top of the food chain. And now a new class of adaptable mesopredators are remaking the ecosystems they take...

In this video, we learn about the fascinating history and characteristics of lobsters. From being considered garbage food to becoming a delicacy, lobsters have come a long way. We discover their habitat, physical features, molting...

The oceans around Antarctica are cold, but full of life. Join Jessi and Squeaks to learn about the blubber of seals, the amazing antifreeze blood of fish, and the shrinking skills of krill.

Jellyfish and other jelly-like animals are more important to the deep ocean food web than previously thought, based on findings from years of video captured by MBARI. ➡ Subscribehttp://bit.ly/NatGeoSubscribe' target='_blank'...

How does climate change affect humans? That's the question we asked Tom Wagner, Program Scientist for Cryospheric Research at NASA. In four different ways, he says, from rainfall patterns and sea levels rising to food production and...

Ice is an essential component of the ecosystem of the Bering Sea region. For example, sea ice cover can dramatically affect the levels of phytoplankton which has enormous effects on the entire food web. In this public radio story we hear...

From spooky-looking towers that belch white "smoke" to a mountain range in the middle of the Atlantic ocean, the seafloor is full of features as dynamic as the surface! That's part of why we've done many SciShow episodes about the ocean....

El Niño years can have a big impact on the littlest plants in the ocean, and NASA scientists are studying the relationship between the two. Ocean color maps, based on a month's worth of satellite data, show El Niño's impact on...
