متن کاملDissolved organic carbon characteristics in boreal streams in a forest-wetland gradient during the transition between winter and summer
[1] The character and quantity of dissolved organic carbon (DOC) were studied in nine small boreal streams and adjacent soils during two years, with focus on the spring snowmelt period. The streams cover a forest-wetland gradient, spanning from 0% to 69% wetland coverage. Lower values of the absorbance ratio measured at 254 nm and 365 nm (A254/A365), in both soil plots and streams, indicated th...
متن کاملModeling stream dissolved organic carbon concentrations during spring flood in the boreal forest: A simple empirical approach for regional predictions
[1] Changes in dissolved organic carbon (DOC) concentration are clearly seen for streams in which chemistry is measured on a high‐frequency/episode basis, but these high‐ frequency data are not available in long‐term monitoring programs. Here we develop statistical models to predict DOC concentrations during spring flood from easily available geographic information system data and base flow che...
متن کاملOverstory vegetation influence nitrogen and dissolved organic carbon flux from the atmosphere to the forest floor: Boreal Plain, Canada
Nitrate, ammonium, total dissolved nitrogen (TDN), dissolved organic nitrogen (DON) and dissolved organic carbon (DOC) concentrations and flux were measured for one year in bulk deposition and throughfall from three stand types (upland deciduous, upland conifer and wetland conifer) on the Boreal Plain, Canada. Annual (November 2006 to October 2007water year) flux rates in bulk depositionwere 80...
متن کاملSeasonal changes in the age and structure of dissolved organic carbon in Siberian rivers and streams
[1] We examined the age and structural composition of dissolved organic carbon (DOC) transported in the Kolyma River, two large tributaries and several small upland and lowland streams in 2003. The sampling took place under ice through the winter and included the spring flood period. Radiocarbon measurements of the DOC indicated that the bulk of the annual DOC flux was modern in origin (DC > 10...
