We present some results of investigations into the laser-induced fluorescence (LIF) of phytoplankton pigments and dissolved organic matter (DOM). The LIF spectra were studied in three regions of the World Ocean, characterized by high bioproductivity, namely, the North Sea and the northeastern part of the Atlantic Ocean, the southwestern part of the Atlantic Ocean, and Pacific coast of Chile, as well as the Sea of Okhotsk. The measurements were carried out in 2002 and 2003 during the time of algae blooming. It is shown that the concentration of the primary phytoplankton pigment, chlorophyll-a, is linearly related to the parameter characterizing the fluorescent part of DOM in the periods of algae blooming. In the water areas, where this relation is observed, it is possible to introduce parameters characterizing the rate of the DOM production by phytoplankton community.
