Abstract: The eddy characteristic in Southern Java Indian Ocean has been investigated and discussed, but spesifically deals about the vertical structure of eddy is still not much. This research was conducted to determine the eddy vertical characteristic and to find out the biggest value of kinematic energy between the cyclonic and anticyclonic eddy. The data set was from NEMO model with parameter are current and temperature from 2014. By using an automated eddy detection the veertical eddies characteristic was set developed, it includes the statistical data of each eddy location, radius, kinematic energy, temperature, and SSH at four vertical levels. The results indicated that cyclonic eddy is mostly formed in Southern Java Indian Ocean in 2014. The temperature in eddy center mostly started changing at a depth of 109 m, which is at the cyclonic eddy has a lower value and at anticyclonic has a higher value.
