# What equilibrium exists between dissolved gas in water and atmospheric gas; how does this equilibrium evolve with temperature?

$\text{Gas in solution "rightleftharpoons" Gas in atmosphere}$
Because a gas is more soluble in COLD water (or cold solvent), fisheries in the northern latitudes (and perhaps southern latitudes) tend to be prolific, presumably because of the availability of dioxygen $\text{dissolved}$ in colder seawater.
