DETECTION OF INTENSE PLANKTON BLOOMS USING THE MERIS OPTICAL IMAGER ON ENVISAT

DETECTION OF INTENSE PLANKTON BLOOMS USING THE MERIS OPTICAL IMAGER ON ENVISAT

The European satellite sensor MERIS (Medium Resolution Imaging Spectrometer) can be used to detect a peak in the optical spectrum of water-leaving radiance at about 705 nm which provides a signature of intense plankton blooms. We present examples of this signature in images and spectra derived from...

In many cases the higher spatial resolution (300 m) provided in the FR mode of MERIS data is important for detecting small area events. The combination of wide area coverage, 300m spatial resolution, and appropriate spectral bands makes MERIS a unique and potentially important tool for global, intense plankton bloom monitoring.
