FIELD: physics.
SUBSTANCE: surface of an investigated water body is continuously irradiated with a laser and mirror reflection glitters from the surface are detected. Upon detecting mirror reflection glitters, the laser radiation power is increased to a level which enables to measure the Raman spectrum from the water column. The Raman spectrum from the water column is measured and then used to determine characteristics of the environment of the water body, e.g., chemical and biological parameters and temperature.
EFFECT: high accuracy of determining vertical distribution of characteristics of an investigated water environment by eliminating the effect on measurement results of surface perturbations generated by wind waves and ripples.
