Abstract

An operational fisheries oceanography system was established to help fishermen analyze the situations of fishery in North Pacific. The system composes of three sub-systems which are a ship-boarding satellite telemetry receiving station, a ship-boarding satellite communication system and a land-based fishery charts producing system. The system can provide some oceanic environmental charts such as sea surface temperature (SST) and relevant derived products which are the most popular use in fishery industry. The accuracy of SST is the most important and affects the performance of the operational system, which is found to be dissatisfactory. Many factors affect the accuracy of SST and it is difficult to increase the accuracy by SST retrieval algorithms and clouds detection techniques. A new technique of temperature error control is developed to detect the abnormity of satellite SST. The performance is evaluated to change the temperature bias from -3.04 to 0.05°C and the root mean square (RMS) from 5.71 to 1.75°C. It is suitable to be employed in an operational satellite-measured SST system and improves the performance of the system in fishery applications.
