3. Oxygen saturation - Wikipedia

   en.wikipedia.org/wiki/Oxygen_saturation

   Dissolved oxygen levels required by various species in the Chesapeake Bay (US). In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O 2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.

4. Winkler titration - Wikipedia

   en.wikipedia.org/wiki/Winkler_titration

   The amount of dissolved oxygen is a measure of the biological activity of the water masses. Phytoplankton and macroalgae present in the water mass-produce oxygen by way of photosynthesis. Bacteria and eukaryotic organisms (zooplankton, fish) consume this oxygen through cellular respiration. The result of these two mechanisms determines the ...

   Measurement of SOD using an oxygen electrode. A: Water, B: Sediment, C: Box, D: Oxygen electrode. Oxygen can be consumed by organisms in the sediment. This process is referred to as sediment oxygen demand (SOD). Measurement of SOD can be undertaken by measuring the change of oxygen in a box on the sediment (benthic respirometer).

7. Oxygen minimum zone - Wikipedia

   en.wikipedia.org/wiki/Oxygen_minimum_zone

   Open ocean areas with no oxygen have grown more than 1.7 million square miles in the last 50 years, and coastal waters have seen a tenfold increase in low-oxygen areas in the same time. [47] Measurement of dissolved oxygen in coastal and open ocean waters for the past 50 years has revealed a marked decline in oxygen content.

   Correcting to a reference oxygen content [ edit ] The following equation can be used to correct a measured pollutant concentration in an emitted gas (containing a measured O 2 content) to an equivalent pollutant concentration in an emitted gas containing a specified reference amount of O 2 : [ 4 ]

9. Alveolar gas equation - Wikipedia

   en.wikipedia.org/wiki/Alveolar_gas_equation

   The partial pressure of oxygen (pO 2) in the pulmonary alveoli is required to calculate both the alveolar-arterial gradient of oxygen and the amount of right-to-left cardiac shunt, which are both clinically useful quantities. However, it is not practical to take a sample of gas from the alveoli in order to directly measure the partial pressure ...
