Results

The SENTIBALT project will develop improved algorithms for assessment of the Baltic Sea conditions and its optically active substances. This will lead to further development of remote sensing methods suitable for complex waters like the Baltic Sea.

The Baltic Sea is one of the world's most threatened marine environments. Inflow of nutrients, such as nitrogen and phosphorus cause eutrophication, which results in the growth of toxic algae. This ecosystem imbalance is particularly characteristic to coastal waters, where nutrients from agricultural and manufacturing lands are accumulated.

The location, shallowness, brackish water and low biodiversity level makes the Baltic Sea a unique and complex ecosystem that requires special assessment methods. Remote sensing of such optically unique and complex coastal and inland waters has been unable to match the method's effectiveness elswhere. Until now measurements have not been able to provide the requires precision necessary for solving environmental problems.
