It’s one of the earliest things you learn in elementary school science class—Earth’s life-sustaining oxygen is produced by plants and algae during photosynthesis using a combination of ...

They’re calibrated.’” Photosynthetic organisms such as plants, plankton and algae use sunlight to produce oxygen that cycles into the ocean depths, but previous studies conducted in the deep ...

The enigma of dark matter continues, and now scientists have discovered what they call dark oxygen on the ocean’s floor. A recent study published in Nature Geoscience, a journal dedicated to ...

Scientists have found evidence that metals naturally occurring on the ocean floor may be able to produce oxygen — a potential “game changer” they say could change our understanding of the ...

Scientists have discovered oxygen is being produced extremely deep below the ocean's surface, changing how we think about ...

Scientists have discovered “dark oxygen” being produced in the deep ocean, apparently by lumps of metal on the seafloor. About half the oxygen we breathe comes from the ocean. But, before this ...

Dark oxygen is being created on the ocean floor, scientists have discovered – and it could change our understanding of how ...

"Dark oxygen" is being produced deep in the ocean, and scientists are baffled by the strange phenomenon, according to a new study. In science class, kids learn that plants need sunlight to do ...

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there.

Mining activity could negatively affect the seafloor ecosystem, scientists warn. Rare metals on deep sea and ocean floors miles below the surface produce "dark oxygen," and mining these minerals ...

Sensor readings seemed to show that oxygen was being made on the seabed 4,000 meters (about 13,100 feet) below the surface, where no light can penetrate. The same thing happened on three ...
