The purpose of this study is to assess the effect of the Child of Krakatoa eruption to the oceanography parameters such as the concentration of chlorophyll-a and sea surface temperature in the waters near Child of Krakatoa by using Aqua Modis satellite image on in March and July 2009. The result of this study is to indicate the increase in the concentration of chlorophyll-a and sea surface temperature in the waters around Mount Child of Krakatoa influenced by volcanic eruption. Concentration of chlorophyll-a in the waters increased after the eruption on 25 March 2009 by 0,22 mg/m-3 in radius 5 kilometers and 0,3 mg/m-3 in radius 10 kilometers. After the eruption on 7 July 2009, concentration of chlorophyll-a increased by 0,25 mg/m-3 in radius 5 kilometers and 0,28 mg/m-3 in radius 10 kilometers. Sea surface temperature in the waters around Mount Child of Krakatoa tend to increase after the eruption on 25 March 2009 with a value that exceeded the maximum standard deviation on 27 March 2009 and tend to decrease after the eruption on 7 July 2009 with a value less than minimum deviation standard. The concentrations of chlorophyll-a and sea surface temperature are higher in the northern waters of Anak Krakatau because the influence of winds that tend to bring volcanic ash towards the north-northwest. The effect of Mount Anak Krakatau eruption on chlorophyll-a concentration in the waters around Mount Anak Krakatau is only seen 1-2 days after the eruption and only lasted in 5-7 days.
