In the Philippines, the presence of meso-scale upwelling is not very well known because they do not seem to have strong surface manifestations, making it undetectable from satellite-derived sea surface temperature (SST) images (Udarbe-Walker & Villanoy, 2001). However, it was found out that there are two potential upwelling areas in the Philippines, namely west of Luzon and east of Mindanao (Udarbe-Walker & Villanoy, 2001). In recent times, Villanoy et al. (2011) documented cooler temperature and high chlorophyll-a concentrations off the coast of Zamboanga Peninsula, Philippines, which could be a good indicator of the upwelling formation (Figure 3).
