1. Terrestrial organic carbon dynamics in Arctic coastal areas : budgets and multiple stable isotope approaches
Abstract : Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. READ MORE

2. The importance of terrestrial carbon in plankton food webs
Abstract : Allochthonous substances, i.e. produced in terrestrial ecosystems, are known to fuel bacterial production in humic lakes. I observed that allochthonous carbon subsidizes bacteria even at high levels of phytoplankton biomass. READ MORE

3. Seasonal variation and landscape regulation of dissolved organic carbon concentrations and character in Swedish boreal streams
Abstract : The seasonal variation and landscape regulation of dissolved organic carbon (DOC) concentrations in streams have been studied in two watersheds in the boreal zone. The seasonal variation was found to be highly correlated to variations in runoff. An increase in runoff was always accompanied with an increase in DOC concentration. READ MORE

4. Organic carbon dynamics in the Baltic Sea : A modelling perspective
Abstract : Coastal seas constitute a link between land and the open ocean, and therefore play an important role in the global carbon cycle. Large amounts of carbon, of both terrestrial and marine origin, transit and are transformed in these waters, which belong to the more productive areas of the oceans. READ MORE

5. Waterborne Carbon in Northern Streams : Controls on dissolved carbon transport across sub-arctic Scandinavia
Abstract : Waterborne carbon (C) forms an active and significant part of the global C cycle, which is important in theArctic where greater temperature increases and variability are anticipated relative to the rest of the globe withpotential implications for the C cycle. Understanding and quantification of the current processes governing themovement of C by connecting terrestrial and marine systems is necessary to better estimate future changes ofwaterborne C.
