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 end of ...

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 ...

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. Ocean darkening occurs ...

The oceans cover over 70% of the Earth’s surface. The marine ecosystem is the largest and most abundant in the world. But most of the ocean is permanently dark and incredibly difficult to observe. As ...

This zone contains a vast amount of marine life, potentially over 90% of all ocean life, and supports important commercial and recreational fisheries. Creatures in the twilight zone help mitigate ...

Seismic data collected by NASA suggests the amount of water hidden in the red planet's crust would cover its surface in a global ocean. Evidence is mounting that a secret lies beneath the dusty red ...
