Remote sensing is used to determine the chlorophyll a concentration and the sea surface temperature. Here, obtained remote-sensed chlorophyll a and sea surface temperature data from MODIS for Manila Bay from 2014 – 2015 was analyzed and initially correlated with the results from the fisheries resources and ecological assessment (this study).
Chlorophyll a concentration was generally concentrated on the eastern part of the bay all throughout 2014. Sea surface temperature was observed to be high during May, July, August, and October 2014. During the first quarter of 2015, a high concentration of chlorophyll a was generally concentrated on the eastern and southwestern part of the bay, while sea surface temperature was high and almost uniform except in the southern side of the bay. The second quarter of 2015 showed that the chlorophyll a is still concentrated in the eastern side of the bay, while the highest sea surface temperature was observed during May reaching more than 30 °C. Comparative analysis indicated that there is a correlation between remote sensing and actual chlorophyll a data vis-à-vis egg and larval aggregations. Further studies are warranted.
