Abstract

The profiles of the light attenuation coefficients, reconstructed using a model based on statistics of bio-argo floats and regional satellite product, as well as measured under natural conditions in the Black Sea, were compared. Additionally, we compared the values of the attenuation coefficient of photosynthetically active radiation – K_d(PAR), obtained on the basis of spectral measurements of horizontal irradiance, with the results of direct measurements of K_d(PAR) on the shelf and the deep-sea parts of the Black Sea. The effects of meteorological conditions, cloudiness on PAR attenuation in the upper and lower the sea layers are demonstrated.
