Dissolved organic matter and lake metabolism: biogeochemistry and controls of nutrient flux dynamics in lakes. Technical progress report, 1 August 1982-31 August 1983

Technical Report ·
OSTI ID:5745490
The interrelated couplings between nutrient loadings from littoral and sediment sources to the open water, and how these fluxes are regulated by the population dynamics of growth, metabolism, senescence, and decomposition of attached littoral and wetland plants (submersed and emergent macrophytes; epiphytic and epipelic microflora) and the phytoplankton (algae and bacteria) have been analyzed. All of the subprograms are coupled to each other and address the general question of quantifying the regulatory capacities of attached macrophytes and microflora for nutrient loadings and recycling, and how these controls affect phytoplanktonic productivity, competition, and succession. The research progressed in three major areas: (1) wetland nutrient fluxes, (2) littoral controls of internal nutrient loadings from sediment sources, and (3) pelagial nutrient turnover and cycling rates.
