Abstract:

Concentrations of total suspended matter and its coarse and fine fractions in surface waters were determined based on the measurements of the light scattering phase function in the Atlantic tropical area. At the same time, the Secchi disk depth Zd was measured. The relationships between the total concentration of suspended matter CTSM and of its coarse Ccoarse and fine Cfine fractions and Secchi disk depth were studied. It was established that the main factor determining the Secchi disk depth in studied area was fine fraction of suspended matter. The effect of fine particles was theoretically analyzed.

Keywords:

Atlantic tropical area, light scattering phase function, Secchi disk, suspended matter
