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 analyses are performed with an SIO/ODF-designed automated oxygen titrator using photometric end-point detection based on the absorption of 365nm wavelength ultra-violet light. The ...

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 ...

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 ...

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 ...

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

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.
