Abstract

In the chemical literature solubility of a gas is generally given as the Bunsen absorption coefficient, α, which is a function of temperature and of the electrolyte content of the solvent. Hydrostatic pressure has little effect on solubility, but with increasing head the escaping tendency of the gas increases. Therefore, at constant concentration, a POS gives a higher reading at greater depth. This effect is negligible (< 1%) at depths less than 100m.
