The geology of the ocean floor is truly spectacular — perhaps even more than land geology. Unfortunately, it's really hard to study.

When we look at Earth from space today, we see a pale blue dot—a planet dominated by vast oceans that shimmer under the sunlight. But what if our oceans weren't always blue? According to recent ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. The reason Earth's oceans may have looked different in the ancient past is to do with their ...

We've always called Earth the blue planet, but that color might not be permanent. Previous research claims our oceans were once green, and if environmental conditions shift dramatically, a new study ...

Far beneath the South Pacific, a continent the size of India has finally stepped out of the cartographic shadows. After ...

Taken from the International Space Station by an astronaut, this is a view of Lake Van off Turkey, the largest soda lake on Earth. This region is prone to major earthquakes because of movement from ...

Earth's oceans may seem like an expanse of the same water to us, but try telling that to a sea turtle or a whale shark. To trace the invisible routes that more than 100 migratory marine species ...

Earth's oceans, known for their deep blue hue, could one day undergo color shifts, say scientists. A report based on a study published in Nature suggests that our oceans have not always been blue, and ...

'There’s been an uptick in that imbalance and that has led to an uptick in the rate of ocean warming.' The two years of heat have created a scientific mystery, with 450 straight days of record high ...

Researchers discovered that continents don’t just split at the surface—they also peel from below, feeding volcanic activity in the oceans. Simulations reveal that slow mantle waves strip continental ...

Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on ocean acidity. The new ...

For roughly 2 billion years of Earth's early history, the atmosphere contained no oxygen, the essential ingredient required for complex life. Oxygen began building up during the period known as the ...
