  2. Degassing - Wikipedia

    en.wikipedia.org/wiki/Degassing

    The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually enhance the efficiency.

  3. Oxygen–argon ratio - Wikipedia

    en.wikipedia.org/wiki/Oxygen–argon_ratio

    Measurements of primary productivity in the ocean can be made using this ratio. The concentration of oxygen dissolved in seawater varies according to biological processes (photosynthesis and respiration) as well as physical processes (air-sea gas exchange, temperature and pressure changes, lateral mixing and vertical diffusion).

  4. Henry's law - Wikipedia

    en.wikipedia.org/wiki/Henry's_law

    In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is directly proportional at equilibrium to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. It was formulated by the English chemist William Henry, who studied the topic in the early 19th ...

  5. Decompression sickness - Wikipedia

    en.wikipedia.org/wiki/Decompression_sickness

    The amount of gas dissolved in a liquid is described by Henry's Law, which indicates that when the pressure of a gas in contact with a liquid is decreased, the amount of that gas dissolved in the liquid will also decrease proportionately. On ascent from a dive, inert gas comes out of solution in a process called "outgassing" or

  6. Physiology of decompression - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_decompression

    Once dissolved, distribution of the dissolved gas is by perfusion, where the solvent (blood) is circulated around the diver's body, and by diffusion, where dissolved gas can spread to local regions of lower concentration when there is no bulk flow of the solvent. Given sufficient time at a specific partial pressure in the breathing gas, the ...

  7. Marine chemistry - Wikipedia

    en.wikipedia.org/wiki/Marine_chemistry

    Marine chemistry, also known as ocean chemistry or chemical oceanography, is the study of the chemical composition and processes of the world’s oceans, including the interactions between seawater, the atmosphere, the seafloor, and marine organisms. [2]

  8. Aquatic respiration - Wikipedia

    en.wikipedia.org/wiki/Aquatic_respiration

    Sea slugs respire through a gill (or ctenidium). Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.

  9. Decompression (diving) - Wikipedia

    en.wikipedia.org/wiki/Decompression_(diving)

    Inert gas such as nitrogen or helium continues to be taken up until the gas dissolved in the diver is in a state of equilibrium with the breathing gas in the diver's lungs, at which point the diver is saturated for that depth and breathing mixture, or the depth, and therefore the pressure, is changed, or the partial pressures of the gases are ...
