| The radiance viewed from the ocean depends on the illumination and viewing geometry along with the water properties, and this variation is called the bidirectional effect. This bidirectional effect depends on the inherent optical properties of the water, including the volume scattering function, and is important when comparing data from different satellite sensors. The current model of f/Q, which contains the bidirectional effect, by Morel et al. (2002) depends on modeled, not measured, water parameters, thus must be carefully validated. In this paper we combined upwelling radiance distribution data from several cruises, in varied water types and with a wide range of solar zenith angles. We compared modeled and measured L(view)/L(nadir) and found that the... |

| Offward transport of surface coastal waters was studied in the Eastern Mediterranean from 31degrees to 37degrees N between 31degrees to 36degrees E using cluster analysis of water-leaving radiance spectra from SeaWiFS color scanner imagery for spring-summer period of 1998. Some types of spectra were found to be characteristic of products of mixing of coastal and offshore waters and served as a quasiconservative tracer of water transport. Three sectors of the eastern coastal zone supplied colored and suspended matter into the open sea areas as occasional pulse discharges of 3-5 week periodicity. The Haifa sector was the most powerful source of such matter producing traceable separate radiance inhomogeneities as far as 200 km west of Haifa. It appears that... |
