in the tropics during times of high river discharge, the oxidation of fine organic material in an estuary's floodwaters commonly leads to oxygen undersaturation (Eyre and Balls 1999).
Mixing of groundwaters may lead to pronounced undersaturation or supersaturation with respect to carbonate minerals, depending on temperature, pressure, and fluid composition, particularly pC[O.

The undersaturated DO concentrations at the Oligohaline site indicate that respiration outweighs production (as was found by Durand and Nadeau, 1972), although it is possible that groundwater of low DO contributed to this undersaturation.
