The maximum thickness is found in the Transitional I monsoon with a thickness of up to 80.28 m. The increase in thermocline thickness in Monsoon Transitional I occurs due to the influence of winds, increased SPL and the entry of the Equatorial Jet which brings warmer currents and the East Indian Current (EIC) which rotates clockwise in the North of the Andaman Sea. }, issn = {2550-0015}, pages = {79--90} doi = {10.14710/buloma.v13i1.54877}, url = {https://ejournal.undip.ac.id/index.php/buloma/article/view/54877} }
