Fish and other aquatic organisms survive in water because of DO. The amount of DO in water is affected by the water temperature, salt concentration, and atmospheric pressure, among other factors.

Dissolved oxygen meters are used to quantify the amount of dissolved oxygen (DO) in surface waters or at different stages of wastewater treatment. There are two dissolved oxygen meters in the ...

Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

The absorption of light by organic molecules with chromophores contribute to the formation of brown carbon in the atmosphere, which can partially counteract the expected cooling effect of aerosols on ...

Modern-day Mars may be more hospitable to oxygen-breathing life than previously thought. A new study suggests that salty water at or near the surface of the red planet could contain enough dissolved ...

AbstractDissolved oxygen (O2) was measured with microelectrodes in shallow subsurface microsites in a prairie stream and related to rates of nitrification determined in the laboratory using the ...

Gigante Salmon adopts nanobubble oxygenation system at Rosøy site. The Norwegian producer says the technology from nanobubble specialist Moleaer has helped stabilise dissolved oxygen levels during ...

A never-before-seen image of individual oxygen atoms dissolved in water has been captured.
