摘　　要： 渔场海温速报是开展渔情分析和确定中心渔场的基础,卫星遥感技术可以快速提供大面积海洋环境参数分布图,由于大洋渔场超出了陆基卫星地面站的接收范围,发展船载遥感系统是提供远洋渔场海洋环境条件的有效途径。本研究介绍基于船载的北太平洋渔场海温速报系统、海表温度遥感反演算法和渔场海温速报产品制作等内容。海温精度分析结果表明,卫星遥感海表温度与船测温度具有良好的一致性,周平均偏差小于0.01℃,RMS平均值为0.7967℃。系统已业务试运行2年,完成北太平洋渔场海温速报产品制作33期,取得了预期目标。 The key information for fishery analysis and locating fishing center are provided by ocean fishery environmental charts, which can be produced from satellite remote sensing data in large areas. Ocean fishery grounds are far away beyond range of land-base receiving stations, but in the coverage of a shipboarding telemetry receiving system which is introduced in this paper. The system consists of four subsystems which are a shipboarding telemetry receiving system, a shipboard realtime ocean environmental condition analysis system, a satellite communication system, and a landbase operational fisheries oceanography system. The statistic analysis shows that satellitemeasured SST using NLSST algorithm has a good consistency with insitu values in North Pacific. The average week bias of temperature is lower than 0.01 ℃ and the average value of root mean square is 0.796 7 ℃. The system has run for two years and the expected goals were achieved with 33 terms of products, which proved the system is a useful tool for ocean fishery analysis.
