Abstract

Eddies are among the most complex phenomena in marine environments, with significant impacts on hydrodynamic parameters. Various intelligent algorithms are utilized to identify and analyze these eddies. In this study, a vector geometry algorithm based on the rotation of velocity vectors was employed to detect and extract eddies in the Persian Gulf. The algorithm utilizes horizontal velocity components from numerical modeling as inputs. Following eddy extraction, their characteristics were thoroughly examined. A total of 4308 cyclonic and 2860 anticyclonic eddies were identified at the surface, with 617 cyclonic and 329 anticyclonic eddies detected at a depth of 50 meters for daily data over one year. Additionally, an investigation into the impact of eddies on sound propagation revealed that warm eddies create areas of severe transmission loss at their centers, leading to divergence in sound rays.
