In this study, we try to mi prove the understanding ofpolarization ofsignal reflected bywatersurface andwith-\ninwaterbody forwhich an accurate knowledge isnecessary in remote sensing applications. Polarized characteristics of the\nreflected light abovewater surface and the scattered light inwaterbody togetherwith their applications in ocean color re-\nmote sensing are reviewed. Elmi ination of the sunglintand skyglint, and inversionmethodsofpolarized ocean color remote\nsensing are summarized in detai.l polarization of sunglint reflected by the sea surface is routinely used to extract informa-\ntion in remote sensing studies, such asoil spilldetection and remote sensing ofsea state. The firstand foremost thing is to\nelmi inate reflected light from water surface radiance for remote sensing ofsubsurfacemateria.l The scope and lmi itationsof\nthe efficiency ofBrewster s angle technique in elmi inating reflected light from water surface radiance is discussed forboth\nflat andwind roughened sea surface. Severalkey problems are pointed out, including atmospheric polarization correction,\nvector radiance transfer calculation, calibration of polarization sensitivity of sensor and polarization characteristics of the\nincident source abovewater surface, the polarization of roughened air-water surface andwaterbody. Some suggestions are\nput forward to mi prove the research ofpolarization information in ocean optics and ocean color remote sensing, such asde-\nvelopmentofpredictive numericalmodels for polarized underwater radiance distribution and quantification of the relation-\nship ofMuellermatrix and the concentration ofwater quality parameters.
