Abstract

The technique of remote sensing chlorophyll pigment concentrations by monitoring sunlight induced fluorescence at 685 nm is an alternative method of surveying the health and productivity of phytoplankton in the oceans . This method measures induced fluorescence from chlorophyll pigments whereas the conventional absorption method measures the reflectance ratio of blue/green channels as an indication of chlorophyll abundance in the water. It should be noted that the method is also differentiated from the laser induced fluorescence technique in which a laser is used to induce the fluorescence, whereas in this method a passive spectroradiometer or imager is used to monitor the occurrence of natural fluorescence under sunlight.
