This thesis aims to study and develop the link between bio-optical data and the remote sensing method to the monitoring and management of the Baltic Sea. The results were applied to the European Union’s Water Directives, and the Baltic Sea Action Plan from the Helsinki commission. The results showed that the use of remote sensing can improve both the spatial and temporal monitoring of water quality, thus facilitating the assessment of the ecological and environmental status within the European Union’s water directives. The spatial patterns make it possible to study the changes of e.g. algae blooms and terrestrial input on larger scales. The thesis shows that bio-optical studies and methods are important for the assessment and interpretations of the effects from eutrophication in coastal areas, as bio-optics contributes to the knowledge of the systems. Good examples on the benefits of incorporating bio-optical and remote sensing data to a higher extent within monitoring and management of the Baltic Sea was also shown.
