Spectral relations of the beam attenuation coefficient with the Secchi depth in the coastal waters of the Southern coast of Crimea

Abstract

The analysis of the optical measurements held in 2008-2014 on a stationary oceanographic platform in coastal waters of the Southern coast of Crimea near the village of Katsiveli is performed. The relationships between the beam attenuation coefficient in eight spectral regions in the wavelength range 416 – 640 nm and the Secchi depth, which varied in the range from 6 to 17.5 m, were established. The spectral distributions of the beam attenuation coefficient at different Secchi depths in coastal waters and in the waters of the deep sea are compared.
