Abstract
A SeaWiFS Photometer Revision for Incident Surface Measurements has been installed on the Helsinki Light House Tower (HLT) in the Gulf of Finland, Baltic Sea, to determine normalised water leaving radiances at centre-wavelengths of interest for ocean colour applications. Additional in situ data are produced twice a week at a distance of 0.5-1 km from the HLT with a ferrybox monitoring system operated on board the MS FINNPARTNER within the framework of the Alg@line project. Ferrybox includes a flow-through system for measuring chlorophyll-a and also for collecting water samples for subsequent laboratory analyses to determine the absorption properties of coloured dissolved organic matter (CDOM), phytoplankton and non-algal particulate matter. The combined use of SeaPRISM and ferrybox measurements is introduced and briefly discussed aiming to show their relevance in assessing remote sensing products of the optically complex coastal waters in the Baltic Sea.
