Abstract: Abstract:The Luzon Strait is a channel between the Philippine Sea and the South China Sea. This area is traditionally classified as an oligotrophic zone with low primary productivity. Even so, high concentrations of pigment were detected 100 km southwest of the Strait through analysis of historical Coastal Zone Color Scanner (CZCS) data that the Nimbus-7 satellite collected during the winters of 1979 to 1986. These blooms were observed in December 1979, February 1983, February 1985, and January 1986, when sea surface temperatures measured with the National Oceanic and Atmospheric Administration's (NOAAs) Advanced Very High Resolution Radiometer (AVHRR) were 23 to 25 degrees C, the lowest in the year. High pigment concentrations (1 to 3 mg m(-3)) persisted for at least 1 to 3 wk and extended over areas of about 100 x 200 km(2). Results of oceanographic survey published in 1995 also showed that a high chlorophyll a concentration (similar to 2.0 mg m(-3)) occurred in the winter of 1980 in this region. The winter phytoplankton blooms in this area appeared to be related to upwelling, which brings nutrients to the surface waters and lowers the water temperature.
