Summary
Observations on the diurnal variations in water chemistry and plankton in two shallow ponds, show large fluctuations in oxygen, pH and correlated changes in carbonate concentrations. A dissolved oxygen concentration of 28.2 p.p.m. was recorded in one pond. Plankton counts suggest that the diurnal migration pattern is not similar to that often found in temperate waters. Nocturnal depletion of oxygen killed fish in one pond.
