Abstract

Sea Surface Temperature (SST) is one of the physical properties of sea surface conditions that are significantly affected by the impact of air-sea interactions, particularly in the Makassar Strait waters. SST variation during ENSO and IOD periods is not only influenced by southeast monsoonal winds but also by El Nino and La Nina periods due to an impact of wind dynamics over the Pacific and the Indian Ocean in the Makassar Strait.
The comparison analysis that seasonal variation of SST and chlorophyll concentration showed a difference in the developing phase between SST and chlorophyll on the surface during June-July-August (JJA). This seasonal variation is clearly evident in the correlation analysis between SST and surface chlorophyll concentration during the southeast monsoon. Further analysis shows that the southern part of Makassar Strait is likely the occurrence of upwelling characterized by an increase in the distribution of chlorophyll concentration which can be identified as one of the potentials for the fishing ground in Makassar Strait.
