Oxygen in a tidal river: Low tide concentration correlates linearly with location

Abstract

Low tide dissolved oxygen concentration correlates with location along the course of the Duplin River, Georgia, a lagoon type tidal river. Concentration generally decreases with distance upstream, although the reverse situation also occurs. The relationship is linear and can be used predictively. The influence on this relationship of tidal circulation, in situ oxygen consumption and production, and rainfall is discussed. © 1976.
