Certain metallic rocks seem to be making oxygen in the dark, without light or sunshine, at the bottom of the ocean.

A startling discovery made public in July that metallic rocks were apparently producing oxygen on the Pacific Ocean’s seabed, where no light can penetrate, was a scientific bombshell.

Languages: English. Deep-sea researchers have launched a groundbreaking project to investigate "dark oxygen"—a form of oxygen produced in total darkness on the ocean floor. The initiative ...

The unidentified victim was inside the chamber, a pressurized container that contains 100% oxygen, when it suddenly exploded just before 8 a.m. at The Oxford Center, located at 165 Kirts Blvd.

Researchers developed an artificial gill for ocean gliders, using hydrogen fuel to improve sustainability and extend mission range.
