The OLS (Operational Linescan System) sensor on board the DMSP (Defense Meteorological Satellite Program) can observe the lights in the night. A nighttime OLS visible-near infrared (VNIR) channel image was overlaid on the simultaneously corrected OLS thermal infrared (TIR) channel image for the area around Japan. The OLS composite image showed a clear relationship between the location of fishing fleet lights detected by the VNIR channel and the sea surface temperature (SST) distribution observed by the TIR channel. Many fishing fleets were located at the cold side of boundary area of warm current and cold current. Since some types of fishes are likely to gather in certain sea temperature zones, the OLS composite image may provide useful information for the fishing fleets monitoring as well as for the marine resources management.
