Description Oceanographic parameters are very important to analyze for determining fishing ground, it is related to upwelling. The aim of the study was to see the analysis of chlorophyll-a concentration at the time of upwelling at Fisheries Management Area (FMA) 716, then verify with the fisheries catch data. The research method is descriptive-analytical and statistical, which aims to describe or provide an overview of chlorophyll-a results from ASCAT imagery on the MetOp and NOAA satellites, and sea surface temperature results from MODIS imagery on the Aqua satellite. Then they processed for statistical correlation using the Pearson correlation method. The results showed that based on spatial and temporal analysis, the parameters that affect the upwelling in FMA 716 are sea surface temperature, so that the water mass moves from west to east, and increase the chlorophyll-a concentration. Pearson correlation shows that the correlation value of chlorophyll-a is higher than the sea surface temperature parameter with a value of 0.72. The fish catches data of yellowfin tuna (Thunnus albacares) appears a positive effect with a correlation value of 0.75. AbstrakKonsentrasi klorofil-a dan suhu permukaan laut merupakan parameter yang dapat dijadikan indikator tingkat kesuburan di suatu perairan, yang berkaitan dengan kejadian upwelling. Tujuan dari penelitian ini adalah menganalisis konsentrasi klorofil-a pada saat kejadian upwelling di Wilayah Pengelolaan Perikanan (WPP) 716, dengan output berupa tabel dan grafik, kemudian diverfikasi dengan data hasil tangkapan. Metode penelitian adalah deskriptif analitis, dan statistik, yang bertujuan untuk mendeskripsikan atau memberi gambaran terhadap data parameter klorofil-a hasil pencitraan ASCAT pada satelit MetOp dan NOAA, dan suhu permukaan laut hasil pencitraan MODIS pada satelit Aqua. Kemudian diolah dan diuji korelasinya secara statistik dengan menggunakan metode korelasi Pearson. Hasil penelitian menunjukkan berdasarkan analisis spasial dan temporal parameter yang mempengaruhi kejadian upwelling pada WPP 716 adalah suhu permukaan laut, sehingga massa air bergerak dari arah barat menuju timur, dan meningkatkan konsentrasi klorofil-a. Korelasi pearson menunjukkan nilai korelasi klorofil-a lebih tinggi dibandingkan parameter suhu permukaan laut dengan nilai sebesar 0,72. Hasil tangkapan ikan Tuna Sirip Kuning (Thunnus albacares) tampak berpengaruh positif dengan nilai korelasi sebesar 0,75.Kata kunci: upwelling, klorofil-a, suhu permukaan laut, Ikan Tuna Sirip Kuning (Thunnus albacares), WPP 716
