Specific Features of the Vertical Distribution of the Beam Attenuation Coefficient in the Short- and Long-Wave Spectral Bands in Deep-Water Layers of the Hydrogen-Sulfide Zone and in the Bottom Layer of the Black Sea

Abstract

On the basis of the data of sounding performed in the deep-water part of the sea down to 1920 m (for a depth of the sea of 2000 m), we study specific features of the vertical distribution of the beam attenuation coefficient in the violet (418 nm) and red (659 nm) spectral bands through the entire thickness of the hydrogen-sulfide zone including the bottom hydrologically homogeneous layer of water. The data of optical measurements performed in the bottom layer for the first time demonstrate that this layer is also optically uniform.
