Vertical light attenuation in the northwestern shelf of the Black Sea in the spring period: direct measurements, modeling and satellite data

摘要

In the paper a joint analysis of direct measurements of the seawater vertical diffuse attenuation coefficient with a satelliteproduct was carried out for several stations on the northwestern shelf of the Black Sea in late April and early May 2017.An attempt to model the empirical spectrum of the seawater vertical diffuse attenuation revealed a number features ofthat were explained by the peculiarity of the vertical structure, namely, by the presence of an optically active layer,which is typical for the considered period of time and is associated with the thermocline formation process.
