Tonizzo, A., J. Zhou, A. Gilerson, J. Chowdhary, B. Gross, F. Moshary, and S. Ahmed, 2009: Multiangular hyperspectral investigation of polarized light in case 2 waters. In Remote Sensing of the Ocean, Sea Ice, and Large Water Regions 2009, 31 Aug. 2009, Berlin, Proc. SPIE, vol. 7473, p. 747306, doi:10.1117/12.830629.

The focus of this work is on the dependence of in situ hyperspectral and multiangular polarized data on the size distribution and refractive index of the suspended particles. Underwater polarization measurements were obtained using a polarimeter developed at the Optical Remote Sensing Laboratory of the City College of New York, NY. The degree of polarization (DOP) of the underwater light field in coastal environments was measured and the water-leaving polarized radiance was derived. In-water optical properties were also measured with an ac-9 (WET Labs). Absorption and attenuation spectra are then used to derive information on the dissolved and suspend components in the water medium which are used in a vector radiative transfer code which provides the upwelling radiance. The model was run for various values of the refractive index of mineral particles until the modeled DOP matched the measured one. The relationship between the intensity of the maximum of the DOP and both the refractive index of the mineral particles and the shapes of their size distributions is analyzed in detail.
