Abstract

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.
