Abstract

The trophic level of marine waters is closely related to the high concentration of nutrients in the water column. One of nutrient indicators is the concentration of chlorophyll-a. The research aims to map the decade of change in Spermonde waters' status with the indicator of chlorophyll-a by utilizing remote sensing technology. The research method used the digital image processing for the analysis of chlorophyll-a concentrations. Data distribution were plotted with kriging techniques and the trophic level was classified based on the Hakanson method. The results showed that there was a change in the trophic level of the Spermonde Islands in 1996-2020. Mesotrophic conditions changed by 166 m and eutrophic conditions by 134 m every year.
