Abstract

In may lakes, high planktonic biomass generates such large quantities that bottom waters become anoxic (Baranovic et al. 1993, Bárdosi et al. 2000, Dévai et al. 2002, Padisák et al. 2003), and massive organic-mineral aggregates occur in the water column, depending on meteorological and biomechanical conditions in the water coloumn (Stachowitsch et al. 1990; Degobbis et al. 1995). Chemical and physical speciation of dissolved organic carbon (DOC) impact the formation of aggregates in marine environment, but few studies have addressed the speciation of DOC in lacustrine ecosystems (V-Balogh et al. 2003). This study reports seasonal variability of DOC, total dissolved carbohydrates (TDCHO), total dissolved free amino acids (TDFAA), and colloidal organic carbon (COC > 1 kDa) in a eutrophic oxbow lake.
