Controls on the Seasonal and Interannual Dynamics of Organic Matter Stable Carbon Isotopes in Mesotrophic Lake Holzmaar, Germany

We investigated the paniculate organic matter (POM) flux and its stable carbon isotope composition in response to changes in phytoplankton primary production and abiotic environmental affects in mesotrophic Lake Holzmaar. POM fluxes were determined by sediment traps emptied biweekly from 1995 to 200...

Description
Summary:We investigated the paniculate organic matter (POM) flux and its stable carbon isotope composition in response to changes in phytoplankton primary production and abiotic environmental affects in mesotrophic Lake Holzmaar. POM fluxes were determined by sediment traps emptied biweekly from 1995 to 2004. Water chemical measurements and meteorological observations were done concurrently. POM fluxes within and directly below the lake's epilimnion were relatively low during winter (
