A groundbreaking study in the journal Science, has unveiled how deep ocean currents—known as global overturning ...

More than one-fifth of the global ocean—an area spanning more than 75 million sq km—has been the subject of ocean darkening over the past two decades, according to new research.

Case in point: Scientists from Tokyo University and Hokkaido University in Japan stumbled across some mysterious jet-black ...

The depths of the ocean are broken into zones. The euphotic zone, or "sunlight zone," extends down to about 656 feet and is where sunlight can penetrate, so plants like phytoplankton and macro ...

The carbonate compensation depth — a zone where high pressure and low temperature creates conditions so acidic it dissolves shell and skeleton — could make up half of the global ocean by the ...

Over the past two decades, more than one-fifth of the world's oceans, an area exceeding 75 million square kilometers, have ...

Is the ocean getting darker? New research found 21% of the global ocean had experienced a reduction in the depth of its lit zones, which are home to 90% of all marine life, during the past 20 ...

In the deepest parts of the ocean, below 4,000 metres, the combination of high pressure and low temperature creates conditions that dissolve calcium carbonate, the material marine animals use to make ...

Dr Huw Griffiths, a marine biologist at the British Antarctic Survey, said: “It’s called the midnight zone because [the] light in the ocean decreases with depth and below 1,000 metres there is ...

In tropical and subtropical waters, between 200 and 500 feet deep, lies the reef twilight zone, or mesophotic coral ecosystem. Very little light penetrates these depths and the realm has long been ...

Hundreds of feet below the ocean’s surface, somewhere between the dark ocean floor and the bright blue shallows, lies the twilight zone. It’s a world of the unknown, but in some tropical and ...
