Abstract
The Makassar Strait is one of the main gate of Arus Lintas Indonesia (Arlindo) which carries water masses from the Pacific Ocean and causes Makassar Strait waters affected by the El Nina and La Nina phenomenon. This study aims to observe the oceanographic characteristics of the Makassar Strait when El Nino and La Nina phenomena occur by looking at the changes in temperature, salinity, and currents from 2009-2010. The data used in this research are sea surface temperature data (CMEMS), Salinity (CMEMS) and current speed (CMEMS) which are processed using Panoply applications and Sea Surface Temperature data from Climate Prediction Center (NOAA) processed into Oceanic Nino Index (ONI). In the period from 2009 - 2019 there were three times the ENSO anomaly phenomenon, which began with the El Nino phenomenon from September 2009 to March 2010, then La Nina in July 2010 to May 2011, and El Nino in May 2015 to May 2016 In each phase, the dynamics of oceanographic characteristics occur in the waters of the Makassar Strait which cause fluctuations in sea surface temperature, salinity, and currents that have interacted to each other
