摘要
赤潮发生时会对海洋环境和渔业资源造成严重的危害,也会给人类健康和安全带来不良影响,因此,赤潮是海洋环境领域的研究热点之一。通过简述赤潮遥感的研究意义和监测依据,然后根据卫星发射时间顺序分别对6种典型的水色卫星/传感器及其遥感反演方法进行概述。20世纪70年代末,国际上就开始了海洋水色卫星遥感的观测工作,40年来,海洋水色卫星的观测能力和水平都得到很大提升,最初的海岸带水色扫描仪(CZCS)仅设置6个观测通道,后来的中等分辨率成像光谱仪(MERIS)设置了15个观测通道;赤潮反演方法也得到不断丰富和发展,主要有叶绿素a浓度、荧光法、温度法、波段差值法与比值法等;目前,全球第一颗地球静止水色卫星(COMS)上搭载的地球同步海洋水色成像仪(GOCI)的应用前景良好,其高观测频率为观测赤潮的日变化提供了可能,可以用于开展赤潮快速变化的相关研究。
The occurrence of red tide could cause large damage and losses to marine environment and fisheries,and bring serious harm to human health and safety.The research on red tide is always one of research hotspots.In this paper,the retrieval principle of red tide from remote sensing was reviewed.According to their launch time,six kinds of satellites/sensors were introduced,including observation capabilities,advantages,shortcomings and relative research work.In the world,the observation and research with ocean colour satellite began in the late 1970s.Over the recent 40 years,the capabilities of observation of ocean colour satellite have been improved greatly.The COGI sensor,the first geostationary ocean colour imager launched in 2009,is helpful in monitoring hourly variations of red tide.At last,the difficulties and problems of remote sensing observation on red tide were discussed,and the prospects for the future development of red tide observation were presented.
