| Zusammenfassung |
| The role of both inorganic and organic riverine nutrient fluxes in regulating the autotrophy vs eterotrophy in coastal seas is well recognized. Eastern Mediterranean rivers have been studied for the most part, for their inorganic nutrient fluxes, whereas little information is available for their organic nutrient content. This study presents new data on dissolved organic matter composition for two permanent Eastern Mediterranean rivers (Evros and Sperhios). Dissolved organic carbon (DOC), nitrogen (DON), phosphorus (DOP), carbohydrates and inorganic nutrients were measured along the studied rivers on a seasonal basis during 2009. Nutrient and carbon dynamics were studied in terms of seasonal changes in water flow and exchange processes at these coastal margins. Additional data on isotopic composition of DOC (δ13C) give an insight on DOC sources. Our results provide new information on dissolved organic matter (DOM) composition, sources and reactivity in E. Mediterranean coastal waters. |
