Quantifying temporal and spatial variations in sediment, nitrogen and phosphorus transport in stream inflows to a large eutrophic lake.
High-frequency sampling of two major stream inflows to a large eutrophic lake (Lake Rotorua, New Zealand) was conducted to measure inputs of total suspended sediment (TSS), and fractions of nitrogen and phosphorus (P). A total of 17 rain events were sampled, including three during which both streams were simultaneously monitored to quantify how concentration-discharge (Q) relationships varied b...
متن کاملRemote sensing of particulate organic carbon dynamics in a eutrophic lake (Taihu Lake, China).
A two step approach was developed to estimate POC concentrations in a shallow eutrophic lake, where dissolved carbon and inorganic particulate matter strongly influence optical properties. The approach was based on the identification of a co-variability of POC concentrations with one or more inherent optical properties (IOPs). In the present case, a relationship between POC and absorption at 62...
متن کاملThe dominant processes of sediment distribution and focusing in a small, eutrophic, monomictic lake
There is evidence for 10 mechanisms of sediment distribution in small lakes. The sediment accumulation rates measured from a common horizon in cores from 64 sites on Esthwaite Water, U.K., were used to determine the relative importance of these mechanisms on the distribution of sediment in the lake. River inflows generally produced localized effects but there were indications of periodic turbid...
متن کاملDistribution and diversity of anaerobic ammonium oxidation (anammox) bacteria in the sediment of a eutrophic freshwater lake, Lake Kitaura, Japan.
Although the emission of N(2) via anaerobic ammonium oxidation (anammox) is a key process in the elimination of nitrogenous compounds from aquatic environments, little information is available regarding its significance and the relevant microorganisms (anammox bacteria) in eutrophic freshwater lakes. In the present study, the anammox bacteria in the sediment of a eutrophic lake in Japan, Lake K...
متن کاملSediminicoccus rosea gen. nov. sp. nov., isolated from the sediment of a eutrophic lake.
A polyphasic study was carried out to clarify the taxonomic position of a novel strain R-30(T) isolated from the surficial layer of sediment from Taihu Lake of China. The strain formed pink colored colonies comprising coccodial cells on R2A agar. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain R-30(T) clustered with the strains of genus Roseococcus and strain Rubri...
