The results of tests of a hydrobiophysical system consisting of a laser meter, for determining the hydrosphere pressure variations in the frequency range from 0 (conventional) to 1000 Hz with an accuracy of 2.45 mPa, and a fluorimeter are presented. It is established that the dynamics of chlorophyll emission in the blue and red spectral bands at a certain depth depends on the hydrosphere processes of the range of wind waves, seiches, and tides.
