Like the sky, water scatters light so that more blue reaches our eyes than other colors. We know that pollutants or an abundance of lifeforms can change the color locally, but it would take a lot ...

Now, the Earth's oceans may be turning green again. Researchers from Nagoya University in Japan used a variety of ...

A new study from Duke showed oceans are getting greener at the poles and bluer in the subtropical regions, like off the SC ...

Naturally, this would have left a dominant green light spectrum, making the oceans appear green. However, during this period, cyanobacteria, the first photosynthetic organisms on Earth, began to ...

Earth’s oceans may not have always been as brilliantly blue as they are today. In fact, there may have been a time when they weren’t blue at all. According to researchers at Japan’s Nagoya ...

A global ocean color shift is underway, with greener waters near the poles and bluer seas in the tropics, impacting many ...

For ages, Earth has been known as a blue planet, a vision largely shaped by the vast oceans that cover three-quarters of its surface. But what if this wasn't always the case, and our oceans used ...

The ocean that nurtured life in the ancient past was 'green'! ~Understanding the evolution of photosynthetic organisms on Earth 2.5 billion years ago~ - Nagoya University Research Results Information ...

It’s hard to picture now, but Earth’s deep blue oceans were once green. According to a new study by Japanese researchers, early photosynthesis helped shift the colour of our seas.

Pictured are coastal area (red) and open ocean (blue) dead zones across from NOAA's 2013 World Ocean Atlas In oceanic 'dead zones', oxygen plummets to levels so low many animals suffocate and die.

Satellite data shows that over the last 20 years, colour shifts from blue to green have occurred over 56 per cent of the world’s oceans. The changes are particularly evident in tropical regions ...
