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. The latter are formed over millions of years, and the metals play a key role in new and green ...
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.
The production of oxygen at the seafloor by polymetallic nodules is a new ecosystem function that needs to be considered when assessing the impact of deep-sea mining.
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
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 ...
The word oxygen in the literature typically refers to molecular oxygen (O 2) since it is the common product or reactant of many biogeochemical redox reactions within the cycle. [37] Processes within the oxygen cycle are considered to be biological or geological and are evaluated as either a source (O 2 production) or sink (O 2 consumption). [36 ...
