   As the chart shows, the concentration of dissolved oxygen in surface water is affected by temperature and has both a seasonal and a daily cycle. Cold water can hold more dissolved oxygen than warm water.

3. DOTABLES - USGS

   water.usgs.gov/water-resources/software/DOTABLES

   DOTABLES is an on-line program that generates tables of dissolved oxygen (DO) solubility values and (or) salinity correction factors over a range of user-specified values for water temperature, barometric pressure, and salinity or specific conductance.

4. Oxygen - Solubility in Fresh and Sea Water vs. Temperature

   www.engineeringtoolbox.com/oxygen-solubility-water-d_841.html

   Normally dissolved oxygen from air in fresh water and sea water (salt water) at pressures ranging 1 - 4 bar abs are indicated in the diagrams and tables below. Note! - in air with normal composition the oxygen partial pressure is 20% of the total pressure.

6. Dissolved Oxygen - U.S. Environmental Protection Agency

   www.epa.gov/system/files/documents/2021-07/parameter-factsheet_do.pdf

   Dissolved oxygen (DO) is the amount of oxygen in water that is available to aquatic organisms. DO is necessary to support fish spawning, growth, and activity. Why do we measure dissolved oxygen? DO is an important indicator of the overall biological health of a waterbody and is required for a waterbody to support aquatic life.

   DOTABLES is an online program that generates tables of dissolved oxygen (DO) solubility values and (or) salinity correction factors over a range of user-specified values for water temperature, barometric pressure, and salinity or specific conductance.

9. Dissolved Oxygen - Water on the Web

   www.waterontheweb.org/under/waterquality/oxygen.html

   As water moves past their gills (or other breathing apparatus), microscopic bubbles of oxygen gas in the water, called dissolved oxygen (DO), are transferred from the water to their blood. Like any other gas diffusion process, the transfer is efficient only above certain concentrations.

10. Dissolved Oxygen - Environmental Measurement Systems

    www.fondriest.com/.../parameters/water-quality/dissolved-oxygen

    Dissolved oxygen refers to the level of free oxygen present in water. Levels that are too high or too low can harm aquatic life and affect water quality.
