Dark oxygen - Wikipedia
Dark oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis. The name therefore uses a different sense of 'dark' than that used in the phrase " biological dark matter " (for example) which indicates obscurity to scientific assessment rather than the ...
The hunt for ‘dark’ oxygen and why it might be more common …
Jan 18, 2025 · Uncovering dark oxygen revealed just how little is known about the deep ocean, and the Clarion-Clipperton Zone, or CCZ, in particular. The region is being explored for the deep-sea mining of...
What is ‘dark oxygen’, found 13,000 feet under the sea?
Jul 24, 2024 · For decades, scientists have floated theories about dark matter, which is believed to hold galaxies together by its gravitational pull. The enigma of dark matter continues, and now scientists...
Scientists discover ‘dark’ oxygen being produced more than ... - CNN
Jul 23, 2024 · New research challenges a long-held assumption about oxygen in the deep sea, with scientists finding oxygen produced without photosynthesis in the Clarion-Clipperton Zone.
Dark oxygen made by deep sea 'batteries' - BBC
Jul 22, 2024 · 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.
Evidence of dark oxygen production at the abyssal seafloor
Jul 22, 2024 · Oxygen is generated abiotically at the abyssal seafloor in the presence of polymetallic nodules, potentially by seawater electrolysis, according to in situ chamber and ex situ incubation...
Mysterious 'Dark Oxygen' Discovered at Bottom of Ocean Stuns …
Chugging quietly away in the dark depths of Earth's ocean floors, a spontaneous chemical reaction is unobtrusively creating molecular oxygen (O 2), all without the involvement of life. This unexpected discovery upends the long-standing consensus that it takes photosynthesizing organisms to produce the oxygen we need to breathe.
Scientists may have discovered 'dark oxygen' created without ...
Jul 24, 2024 · It has long been understood that photosynthesis creates oxygen, but researchers believe they've found oxygen being created in parts of the ocean with no light.
Bizarre Mineral Clumps Make ‘Dark Oxygen’ on Deep Seafloor
Jul 22, 2024 · Metal deposited over millions of years forms these nodules, which can somehow generate oxygen. The dark seabed of the Pacific Ocean’s Clarion-Clipperton Zone (CCZ) is littered with what...
Discovery of 'dark oxygen' from deep-sea metal lumps could …
Jul 22, 2024 · In a global first, scientists working in the Clarion-Clipperton Zone in the North Pacific Ocean have found that metallic nodules on the seafloor produce their own oxygen, dubbed "dark oxygen."
