Laser induced fluorescence spectra dynamics of the seawater biooptical components during phytoplankton cells inhibition

摘要

Dynamics of the chlorophyll "A" and dissolved organic matter fluorescence induced by laser radiation at 355 and 532 nm was analyzed. Formation of the seawater laser induced fluorescence spectra was investigated during photosynthesis cells destruction and dissolved organic matter (DOM) degradation processes. Experiments were carried out in laboratory conditions. It was showed that decreasing of the intensity of the chlorophyll "A" fluorescence connected with increasing of the dissolved organic matter fluorescence. Fluorescence spectra dynamics is differ for 355 and 532 nm laser radiation wavelengths.
