Oil-spill detection from radar imagery is complicated task in Estonian coastal sea where look-alikes caused by ice, upwelling events, cyanobacterial blooms may occur. We compared SAR image with the MODIS optical imagery and look-alikes caused by upwelling event and cyanobacterial bloom were detected from images of August 7, 2007. Analysis of MODIS imagery from years 2000-2006 showed that during the ice free period upwellings occur frequently in the Gulf of Finland and they are strongest during summertime stratification period. Cyanobacterial blooms occurred in July and August in Estonian coastal sea. Some ice cover is present in Estonian coastal sea every winter.
