Banda Sea is a region which affected by various factors that can cause an upwelling and downwelling. The purpose of this study is to analyze the distribution patterns of upwelling and downwelling in Banda Sea. Data used in this study are chlorophyll-a, sea surface temperature (SST), sea level anomaly (SLA), geostrophic velocity and wind from 2015-2016. These data are level 4 satellite data and taken from MARINE COPERNICUS. The results from this study is upwelling in 2015(El Niño) at Banda Sea start from May until October, while in 2016 (La Niña start to occurs) upwelling start from May to September. The strongest upwelling occurs in July at northern of Yamdena Island with a strong upwelling intensity, which indicated by low SST and SLA along with increasing of chlorophyll-a concentration (1,7 mg/m3). Downwelling occurs in West Monsoon and Transition Monsoon I, with its peak in April, which indicated by high SST and SLA along with lowe concentration of chloropyll-a. When the El Niño occur, SST and SLA in Banda Sea decreasing and when the La Niña occur the SST and SLA in Banda Sea is increasing. Mean concentration of chlorophyll-a at Banda Sea in 2015 is higher than 2016 because of EL Niño in 2015 and La Niña in 2016.
