This paper discusses the application of acoustic sounding with the purpose of identifying vortical features in the sea. Analysis
of the results of a multidisciplinary acoustic/hydrological experiment conducted in the Black Sea has revealed a stable recurrent
correlation between the amplitudinal variance of echo signals, on the one hand, and the peculiarities of water temperature
fields, on the other. Given these characteristics, the peripheral and the central areas of a mesoscale eddy essentially differed.
This allows us to apply acoustic sounding to identify mesoscale eddies in the sea.

Visualization of a collapsing vertical packet of patches in a laboratory experiment and the results of acoustical sounding under field conditions allowed us to discriminate the stage of its evolution which was previously unknown. It is defined by the variations of the horizontal dimensions of patches and their effective scattering surface with a period ofT=150–250/N, whereN is the Brunt-Väisälä frequency. The horizontal dimensions of patches can reach 40% of their final dimensions at the evolution stage discriminated.Translated by Mikhail M. Trufanov. 相似文献
