Express method for chlorophyll concentration assessment

We propose this fluorescent express method for the assessment of the chlorophyll a concentration in seawater. The method is based on spectral fluorescence measurements obtained with excitation at different wavelengths. A relatively simple two-channel laser spectrometer is used for measurements. In t...
