Wind-driven Coastal Upwelling Along South of Sulawesi Island
The sea in the vicinity of south of Sulawesi Island (SSI) is influenced by monsoon winds. The present observation shows that coastal upwelling in the region is a dominant process leading to high chlorophyll-a (Chl-a) concentration during southeast (SE) monsoon season. Southeasterly monsoon winds are responsible for the upwelling formation.The objective of the reseach was to describe the wind-driven upwelling occurrence. The bloom increases gradually, starting in May and climbing up to peak value (1.1 mg/m3) in August, then weakens in September. By utilizing a combination of satellite data of sea surface wind vector, sea surface temperature (SST), and surface Chl-a, the physical mechanism of the coastal upwelling in the SSI is investigated.
Keywords : coastal upwelling, satellite remote sensing, wind speed, SST, Chl-a, south of Sulawesi island.
Perairan di sekitar selatan Pulau Sulawesi dipengaruhi angin monsoon. Observasi menunjukkan bahwa upwelling pantai di perairan tersebut merupakan proses dominan yang menyebabkan meningkatnya konsentrasi klorofil-a selama musim monsoon tenggara. Tujuan penelitian ini adalah menggambarkan kejadian wind-driven upwelling. Angin monsoon dari tenggara adalah penyebab terbentuknya upwelling. Konsentrasi klorofil-a naik secara bertahap, dimulai di bulan Mei dan mencapai maksimum (1.1 mg/m3) di bulan Agustus, kemudian berkurang di bulan September. Menggunakan kombinasi data satelit dari angin permukaan laut, suhu permukaan laut, Chl-a permukaan, mekanisme fisik dari upwelling pantai di perairan di selatan Pulau Sulawesi
Kata kunci : upwelling pantai, satelit penginderaan jauh, kecepatan angin, suhu permukaan laut, klorofil-a, selatan Pulau Sulawesi.
