The Atlantic Meridional Overturning Circulation (AMOC) serves as the Atlantic Ocean's conveyor belt, transporting warm water north toward the Arctic Circle and returning cold, dense water back to the tropics. Nearshore areas off Greenland are critical...

Small change in Earth’s oxygen levels may have sparked huge evolutionary leap

New research provides the clearest evidence yet that the Cambrian explosion—a rapid burst of evolution 540 million years ago, could have been triggered by...

Oceanographers uncover the vital role of mixing down of oxygen in sustaining deep sea health

New research led by oceanographers from the School of Ocean Sciences at Bangor University has shown for the first time the important role of...

Jupiter’s moon Europa produces less oxygen than we thought—it may affect our chances of finding life there

Jupiter's icy moon Europa has long been thought of as one of the most habitable worlds in the Solar System. Now the Juno mission...

Earth’s deep ocean oxygen levels are declining, shows study

Antarctica is a unique landscape, full of mystery and wonder. Its environments have a huge impact on the rest of the planet—on the climate,...

Researchers defend their theory that molecular oxygen existed on Earth 2.5 billion years ago

When did molecular oxygen, the gas that all large and complex forms of life on Earth today require to function, first appear on Earth? For...

Where did the Earth’s oxygen come from? New study hints at an unexpected source

The amount of oxygen in the Earth's atmosphere makes it a habitable planet. Twenty-one percent of the atmosphere consists of this life-giving element. But in...

Ancient source of oxygen for life hidden deep in the Earth’s crust

Scientists at Newcastle University have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. The pioneering...
