【 摘 要 】

Chlorophyll-a is one of the most decisive parameters of the fertility waters. The dynamics of the distribution Chlorophyll-a concentration depends on the oceanographic conditions, so it can change according to the circumstances of the environment and the season. This study aims to determine the distribution of Chlorophyll-a in the northern waters of Central Java temporally and spatially. This assessment was conducted based on Chlorophyll-a data from the Aqua MODIS (Moderate Resolution Imaging Spectroradiometer) satellite in 2010-2016. MATLAB R2014a was used in processing data to see the distribution of Chlorophyll-a. The distribution of Chlorophyll-a appears that there are difference patterns for monthly and seasonal ocean productivity in the northern waters of Central Java. The highest fertility occurs in May, during the dry season. These waters are more fertile on the coastal areas than offshore areas, because determined by nutrients from the foreshore.
