It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current ...

A colossal ocean current encircling Antarctica—stronger than all the world’s rivers combined—played a far more complex role in shaping Earth’s climate than scientists once thought. New research shows ...

Dating back to Ancient Greece, we’ve known Earth’s rotation takes about 24 hours to complete. Since then, we’ve updated our ...

The world's oceans may be quietly amplifying climate change in ways scientists are only beginning to understand. In a new ...

Scientists have found a new way to detect subtle chemical signatures in seawater—revealing previously invisible details about ...

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 ...

Scientists have finally cracked a long-standing mystery about squid and cuttlefish evolution by analyzing newly sequenced ...

(CNN) — Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly ...

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 ...
