This upwelling area is indicated by high chlorophyll-a (Chl-a) concentrations due to a strong easterly wind-induced upwelling. However, the investigation of Chl-a variability is less studied along the western coast of South Sulawesi. By taking advantages of remote sensing data of Chl-a, sea surface temperature, surface wind, and precipitation, the present study firstly shows that along the western coast of South Sulawesi, there are two areas, which have high primary productivity occurring during the rainy season. The first area is at 119.0\u00b0 E\u2013119.5\u00b0 E; 3.5\u00b0 S\u20134.0\u00b0 S, while the second area is at 119.0\u00b0 E\u2013119.5\u00b0 E; 3.5\u00b0 S\u20134.0\u00b0 S. The maximum primary productivity in the first (second) area occurs in April (January). The generating mechanism of the high primary productivity along the western coast of South Sulawesi is different from its southern coast. The presence of river runoff in these two areas may bring anthropogenic organic compounds during the peak of rainy season, resulting in increased Chl-a concentration.<\/jats:p>","DOI":"10.3390\/rs13234833","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T01:45:02Z","timestamp":1638323102000},"page":"4833","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["High Chlorophyll-a Areas along the Western Coast of South Sulawesi-Indonesia during the Rainy Season Revealed by Satellite Data"],"prefix":"10.3390","volume":"13","author":[{"given":"Anindya","family":"Wirasatriya","sequence":"first","affiliation":[{"name":"Department of Oceanography, Faculty of Fisheries and Marine Sciences, Diponegoro University, Semarang 50275, Indonesia"},{"name":"Center for Coastal Disaster Mitigation and Rehabilitation Studies, Diponegoro University, Semarang 50275, Indonesia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1495-5951","authenticated-orcid":false,"given":"Raden Dwi","family":"Susanto","sequence":"additional","affiliation":[{"name":"Department of Atmospheric and Oceanic Science, University of Maryland, College Park, MD 20742, USA"},{"name":"Faculty of Earth Science and Technology, Bandung Institute of Technology, Bandung 40132, Indonesia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2948-9204","authenticated-orcid":false,"given":"Joga Dharma","family":"Setiawan","sequence":"additional","affiliation":[{"name":"Center for Coastal Disaster Mitigation and Rehabilitation Studies, Diponegoro University, Semarang 50275, Indonesia"},{"name":"Department of Mechanical Engineering, Faculty of Engineering, Diponegoro University, Semarang 50275, Indonesia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8645-354X","authenticated-orcid":false,"given":"Fatwa","family":"Ramdani","sequence":"additional","affiliation":[{"name":"Geoinformatics Research Group, Faculty of Computer Science, Brawijaya University, Malang 65145, Indonesia"},{"name":"Graduate School of Humanities and Social Sciences, University of Tsukuba, Tsukuba 305-8571, Japan"}]},{"given":"Iskhaq","family":"Iskandar","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculty of Mathematics and Natural Sciences, Sriwijaya University, Indralaya 30662, Indonesia"}]},{"given":"Abd.
