The correlation between sea surface temperature and chlorophyll-a concentration

The examination of the correlation between sea surface temperature and chlorophyll-a concentration is essential for facilitating the surveillance and evaluation of marine ecosystems. Chlorophyll-a functions as a gauge of the prevalence of plant plankton and biomass in coastal waters, whereas sea surface temperature is a determinant that impacts the proliferation of plant plankton. This study aims to investigate the relationship between sea surface temperature and chlorophyll-a concentration on the surface of the sea. The case study was conducted in the upper Gulf of Thailand, Chonburi Province, in the year 2566 using data from the Aqua/MODIS satellite. Study results indicate that the amount of chlorophyll-a produced in 2022 ranged from 0.369 µg/L to 5.714 µg/L. When the amount of chlorophyll-a was correlated with the sea surface temperature, a high level of correlation was observed, with a regression coefficient of 0.859.
