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 photometric meaning.
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 rare ...
Scientists discover ‘dark’ oxygen being produced more than 13,000 feet below the ocean surface
Scientists discovered "dark oxygen" produced by deep-sea polymetallic nodules deep below sea level, redefining our understanding of ocean and early Earth life. 4,000 Meters Below Sea Level ...
The manganese nodules act as a kind of battery as they contain different metals, and they release oxygen into the environment. Because it was previously thought that only plants and algae produce dark oxygen (oxygen produced without light), this can be seen as a scientific breakthrough.
Oxygen was isolated by Michael Sendivogius before 1604, but it is commonly believed that the element was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774. Priority is often given for Priestley because his work was published first.
Scientists who recently discovered that metal lumps on the dark seabed make oxygen, have announced plans to study the deepest parts of Earth's oceans in order to understand the strange phenomenon.
Photosynthetic prokaryotic organisms that produced O 2 as a byproduct lived long before the first build-up of free oxygen in the atmosphere, [5] perhaps as early as 3.5 billion years ago. The oxygen cyanobacteria produced would have been rapidly removed from the oceans by weathering of reducing minerals, [citation needed] most notably ferrous ...
