Correlations Between Depth Distributions of Water Attenuation Coefficient and Density in the North Seas
Abstract
The paper contains the data on measurements of depth distributions of attenuation coefficient and fluid density in the Barents, White and Kara Seas together with results of analysis the correlations between these distributions. We founded that in many cases correlations between parameters of the functions used for distributions approximation are rather high, namely, between the horizons of maximal change of attenuation coefficient and the pycnocline depth, between widths of pycnocline and the layer of attenuation coefficient jump, as well as between the gradient of c and the buoyancy frequency.
