Abstract

Investigations of diel cycles of trace metals in relation with carbonate cycles were conducted in Ichetucknee River, a spring-fed river flowing over carbonate karst terrain in north-central Florida (USA). Ca and bicarbonate cycles reflect photosynthetically enhanced calcite precipitation during the day. Cu, Fe and Mn also undergo diel variation showing an inverse correlation between Mn and Fe. Mn appears to co-precipitate with the calcite, but Fe and Cu, which co-vary, appear to be controlled by photo-reduction enhanced by the clarity of the water.
