Abstract

The characteristics of the eastern part of Bintan Island, the movement of the monsoon winds, the movement of the monsoons and the circulation of sea air that occur have an influence on the fluctuations in the distribution pattern of chlorophyll-a and SST concentrations. Studies related to the distribution pattern of Sea Surface Temperature, Chlorophyll-a and Wind Speed Direction based on differences in seasons. This research was conducted in October 2020. The method used was the chlorophyll-a image processing method, the sea surface temperature extracted through the Aqua MODIS image averaged monthly for 3 years. The results showed that the temperature distribution pattern in Bintan Island waters fluctuated based on seasonal support, an increase in temperature occurred in the eastern monsoon ranging from 29.88-30.53°C and a decrease occurred in the northern monsoon ranging from 28.48-28.51°C . The distribution pattern of chlorophyll-a in Bintan Island fluctuates based on seasonal differences, the concentration of chlorophyll-a has increased in the southern monsoon ranging from 0.74-1.32 Mg/M3 and decreases in the west monsoon ranges and West monsoon ranges from 0.45 to 0, 52 Mg M3. The movement of the wind direction in Bintan Island waters is dominated by wind movements, in the north and south monsoons the wind moves based on the season and in the east and west monsoons the direction of the wind movements by the previous season. The highest wind speed occurs in the northern monsoon
