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.

Limnology and Oceanography, Vol. 58, No. 4 (July 2013), pp. 1312-1318 (17 pages) The isotopic composition of dissolved O₂ (17Δ) and the biological O₂ saturation from O₂ : Ar ratios were measured in ...

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 ...

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 ...

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 ...

Salty water buried just beneath the Martian surface could have enough dissolved oxygen to support microbes, and perhaps even simple animal life such as sponges in some places, a new study suggests.

Scientists have directly imaged atomic oxygen in water using a femtosecond laser, revealing unexpected stability and movement ...
