Abstract

QUANTIFYING SINKS OF TERRESTRIAL DOC IN THE BALTIC SEA

The fate of terrestrial carbon in the oceans and what role it plays in the carbon cycle is still unclear. As the discharge of terrestrial carbon into coastal seas is expected to increase with global warming, there is a need to better understand its dynamics in the marine environment. In this study we are aiming to quantify the internal sinks of terrestrial dissolved organic carbon (DOCter) in the Baltic Sea by releasing it as tracers with different degradation rates into a 3D circulation model of the estuary. When comparing the results of the model to previously observed concentrations of DOCter, we found that the DOCter has a degradation rate of ~ 10 years in the Baltic Sea and that 80% of it is removed before reaching the North Atlantic Ocean.
