Spatial and temporal variability of chlorophyll-a concentration in makassar strait using empirical orthogonal function analysis of satellite images

Research output: Contribution to journalArticle

Abstract

Nine years of monthly data of MODIS derived chl-a around Makassar Strait of Indonesia were used to investigate the spatial and temporal variability of chl-a concentration. The variability was further analyzed by empirical orthogonal function (EOF). The first mode (62.08% of variance) showed variability of seasonal pattern. The second mode (5.75% of variance) showed variability during the Northwest monsoon and the Southeast monsoon. Meanwhile, the third mode (2.72% of variance) and the fourth mode (2.25% of variance) showed variability during the Transition monsoon I and II, respectively.The variability of chl-a along the Borneo Island is influenced by river runoff during the Northwest monsoon, while the variability of chl-a along the Sulawesi Island is induced by strong wind and current during the Southeast monsoon.
