Long-term Trends of Organic Carbon Concentrations in Freshwaters: Strengths and Weaknesses of Existing Evidence
Many articles published in the last few years start with the assumption that the past decades have seen an increase in dissolved organic carbon (DOC) concentrations in the rivers and lakes of the Northern Hemisphere. This study analyses whether the existing evidence supports this claim. With this aim, we have collected published studies where long series of organic carbon concentrations (i.e., ...
متن کاملInorganic carbon dominates total dissolved carbon concentrations and fluxes in British rivers: Application of the THINCARB model - Thermodynamic modelling of inorganic carbon in freshwaters.
River water-quality studies rarely measure dissolved inorganic carbon (DIC) routinely, and there is a gap in our knowledge of the contributions of DIC to aquatic carbon fluxes and cycling processes. Here, we present the THINCARB model (THermodynamic modelling of INorganic CARBon), which uses widely-measured determinands (pH, alkalinity and temperature) to calculate DIC concentrations, speciatio...
متن کاملTemperature Dependence of Photodegradation of Dissolved Organic Matter to Dissolved Inorganic Carbon and Particulate Organic Carbon
Photochemical transformation of dissolved organic matter (DOM) has been studied for more than two decades. Usually, laboratory or "in-situ" experiments are used to determine photodegradation variables. A common problem with these experiments is that the photodegradation experiments are done at higher than ambient temperature. Five laboratory experiments were done to determine the effect of temp...
متن کاملYellow Matters Improving the remote sensing of Coloured Dissolved Organic Matter in inland freshwaters
De hoeveelheid opgeloste organische stoffen (Dissolved Organic Matter DOM) in oppervlaktewater, en de samenstelling ervan, is een belangrijke graadmeter van de fysisch-chemische waterkwaliteit. Dit proefschrift beschrijft een drietal mogelijkheden om de concentratie van gekleurde opgeloste organische stoffen (Coloured Dissolved Organic Matter CDOM) in natuurlijke Nederlandse oppervlaktewateren ...
