A recent study hypothesizes that the nodules are a source of "dark oxygen", oxygen produced without light, which provides the seafloor in the deep ocean with oxygen. [36] However, this study contrasts with many other studies conducted over decades in the deep sea that did not detect oxygen production - and in fact showed only oxygen consumption.
The region is being explored for the deep-sea mining of rare metals contained in the rock nodules. ... Ruff ultimately discovered that microbes in the water were producing oxygen. The microbes had ...
The discovery that abyssal, or deep-sea, nodules are producing oxygen is “an amazing and unexpected finding,” said Daniel Jones, a professor and head of ocean biogeosciences at the National ...
They have found that manganese nodules on the deep sea floor produce free oxygen from water molecules. [11] The manganese nodules act as a kind of battery as they contain different metals, and they release oxygen into the environment.
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 ...
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.
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.
Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.
