Before altering the air, microbes oxygenated large swaths of the sea

Hundreds of millions of years before oxygen surged in the atmosphere 2.4 billion years ago, swaths of oxygen winked in and out of existence in the ocean.

Microbes provided oxygen to extensive areas of the ocean before the air began to modify its chemical composition

It is probable that ancient microbesCelui-citizens-making oxygenated vast areas of Earth's seafloor centuries before the element filled the...

Unusual Microbes Offer Insights into the Ancestors of Complex Life

Additionally, the oxygenation of Earth’s atmosphere may have significantly contributed to this development. These findings bring researchers closer [...] Source The post Unusual M…

Ancient oxygen microbes can have a large oxygen band from the Earth's seabed hundreds of millions of years before the element fills the atmosphere. Geochemical analysis of sediment deposited about 2.6 billion years ago reveals that oxygen pulses may have swept away large areas of the ocean, according to researchers [...]

Artificial oxygenation in coastal waters

As oxygen levels in coastal waters worldwide continue to plummet, researchers are exploring whether artificial oxygenation could offer a lifeline to marine ecosystems on the brink While this approach has shown promising results in lakes and small water bodies, experts now warn that using it in the ocean has significant risks and limitations. Oxygen: A vital lifeline for marine life Oxygen is essential to marine life, and its decline has already …
