IMAGING CHLOROPHYLL AND SEDIMENT PATTERNS IN COASTAL WATERS USING SATELLITE SENSORS

The first images from MODIS continue the expanding sequence of satellite data available for monitoring coastal areas. This sensor adds the possibility of mapping the in-vivo fluorescence signal near 685 nm from chlorophyll a that is stimulated by sunlight. In March 2002, ESA plans to launch the MERIS imager which will have the advantages of higher spatial resolution, and flexible band placing. MERIS should also detect bright plankton blooms (red-tide events) through the peak radiance in a band at 708 nm. In the past (back to September 1997) Seawifs has been available for mapping coastal water colour, and back to about 1989 the AVHRR weather satellite scanners have given images of bright plankton blooms and river plumes. In this paper we present examples of imaging plumes and plankton blooms with AVHRR, Seawifs and MODIS. Data from MERIS will be presented if available before the conference.
