In this paper, the development status of application research on red tide monitoring by using airborne hyperspectral remote sensing i n China is presented, and the developed techniques, including the red tide detec tion, dominant species identification, biomass estimation and hyperspectral data base of red tide orgamism are introduced in detail. The advances in application of hyperspectral remote sensing to oil spill, sea ice and typical elements in th e coastal zone are also summarized. The prespect for the development of remote s ensing platform and imaging spectrometer is offered, and a brief introduction to the first Chinese integrated airborne multi-sensor system for marine applicati on (IAMSMA) is made. Finally, three key points for developing the application re search in China are proposed, they are (1) the acquisition of a vast amount of h yperspectral data of marine and coastal elements, (2) in-situ spectral data acq uisition of marine and coastal elements and (3) construction of ground spectral database of marine and coastal elements.
