Dark oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis.

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...

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...

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.

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.

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...

Jul 26, 2024 · Yet, the life-supporting gas is abundant in this darkness-cloaked region, thanks to an unlikely oxygen factory: potato-sized, “battery rocks” on the 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...

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.

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."
