Primary acoustic characteristics of waters in the North-West Atlantic synoptic-scale vortical features

The CTD survey data collected in the course of implementation of the POLYGON-70 and POLYMODE projects are applied to gain a deeper insight into the structure of the sound speed field and elements of its vertical stratification in the areas of synoptic-scale vortical formations of the North-West Atlantic. The effect of vortical features on the structure of the acoustic fields is studied in the ray approximation. Translated by Vladimir A. Puchkin.
