Abstract

This study investigated the relationship between sea surface temperature (SST) and chlorophyll-a (chl-a) concentration in the North Coast of Semarang, Indonesia. The data were collected using Moderate Resolution Imaging Spectroradiometer Satellite (Aqua-MODIS) chl-a level-3 standard mapped image for a period of five years (2015–2019). Due to cloud coverage, monthly averaged data were used in this study. The result shows that monthly averaged SST ranged from 28.1°C to 31.3 °C. This SST is relatively higher in the transition season (especially in the first transition season) compared to the east and west monsoons season. Chl-a concentration ranged from 0.002 mg/m3 to 1.388 mg/m3. This concentration fluctuates according to the seasonal winds. The maximum concentration of chl-a occurred in the west monsoon season, while the minimum one happened in the second transition season. Using the Pearson correlation coefficient, the correlation is -0.092, which indicates a weak negative correlation between SST and chl-a concentration. This study is expected to give an insight into the potential fishing ground since the chl-a concentration can be such an indicator for the presence of fish.
