The authors present data from four different satellite sensors,which have been acquired over the same sea area during an algae bloom,within less than two hours. The data includes: the Thematic Mapper (TM)on Landsat-5, the synthetic aperture radar (SAR) aboard the SecondEuropean Remote Sensing Satellite (ERS-2), the Wide Field Scanner (WiFS)aboard the Indian IRS-1C satellite, and the Advanced Very HighResolution Radiometer (AVHRR) flown on the NOAA-14 satellite. Using thisextensive data set, for the first time, an investigation of theusefulness of the fusion of different remote sensing data (particularlyby incorporating radar data) for monitoring of an ongoing algae bloomhas been performed. The results of their analysis show that the fusionof optical and microwave remote sensing data (even with differentspatial resolutions) can yield more information about the biological andoceanic characteristics of sea surface areas
