Phosphorus dynamics in some coastal plain estuaries
Conference
·
OSTI ID:7184758
Phosphorus availability in estuaries may have a seasonal cycle with a maximum usually occurring in the summer when orthophosphate is released into oxygen depleted deep water and transported to the euphotic zone by turbulent mixing. Superimposed on the annual fluctuation of total phosphorus is the rapid turnover of orthophosphate and phosphorus monoesters in the euphotic zone. The concentrations of these materials in surface waters are similar and phosphate uptake kinetics from each type by natural phytoplankton assemblages are similar which suggests that phosphorus monoesters may be significant in phytoplankton phosphorus nutrition.
