Abstract:

The projects objective is to demonstrate a method for predicting the quantitative and qualitative distributions of CDOM in the littoral zone based on combined model of CDOM biogeochemical cycling and physical oceanography. This approach provides the Navy with an alternative technique by which to gauge the performance of satellite based predictions of CDOM distributions. The field work of this project was carried out in the Baltic Sea-North Sea mixing zone at the entrance to the Baltic Sea. The Baltic Sea is a large fjord greatly influenced by freshwater inflow from its large drainage basin and having a limited exchange with the North Sea Atlantic Ocean. As a result its waters have a high content of terrestrially derived organic material. Danish marine monitoring cruises with RV Gunnar Thorson were used as a sampling platform for the project. The cruises covered 26 stations Figure 1. Samples were taken for optical and chemical measurements of dissolved organic matter. Data for other water constituents and properties were made available from the monitoring program temperature, salinity, chlorophyll, nutrient concentrations.
