Opis:: The phenomenon of Indian Ocean Dipole (IOD) can influence the variability of eddy in the Southern Java Ocean (SJO). The purpose of this research is to know the characteristics of eddy in the SJO at the time of the IOD condition. The research was conducted in Eastern Indian Ocean (EIO), South of the Java Island by coordinate 0º S – 15º S and 90º E – 120º E. The data used in this research is currents data, sea surface height (SSH) data, and temperature data from HYCOM, and Dipole Mode Index (DMI) data from Japan Marine Science and Technology (JAMSTEC). Methods used for detecting eddy is using the Automated Eddy Detection (AED) method. The results of this research show that the IOD phenomena affect the variability of eddies in the SJO, this is evidenced by the difference of the total eddies is generated at the time of normal conditions and at the time was going to the phenomenon of IOD. Total average eddies on IODM (+) conditions is 153 and on IODM (-) conditions is 144. IODM (+) conditions could cause the value of a central point of sea surface height (SSH) and sea temperature is lower than the normal conditions, the opposite IODM (-) conditions can cause the value of a central point of SSH and sea temperature is higher than the normal conditions.

Opis:: One of the complexities of the ocean currents in the territorial waters of Indonesia is oceanic eddies form. Ocean eddy is one of the very crucial phenomena in the ocean due to its circulation and connection with the chemical and biological aspects in the water column. This study aimed to observe the distribution of oceanic eddies associated with the Sea Surface Temperature (SST) and Sea Surface Height (SSH) with the Automatic Eddy Detection (AED) method. The analysis included distribution and types correlated with seasons. The results showed that eddies occur in all regions in the Indonesian Seas except the Java Sea. In general, the occurrence of eddies every month does not differ significantly for both Ocean Cyclonic Eddies (OCE) and Ocean Anticyclonic Eddies (OAE). The total oceanic eddies in a year are around 1,149 events. A minimum radius of the ocean eddies found was about 5.08 km, and a maximum was around 386.76 km. Furthermore, the occurrence of OCE is mostly in locations that are almost the same as OAE. Both types of eddy are mostly in locations with the boundary of temperatures and the boundary of SSH. Several eddies exist every month and mostly change or move into other areas. Eddies in Indonesia seas are influenced by differences of SST and different SSH that form ocean currents.
