Polarized Light in Coastal Waters: Hyperspectral and Multiangular Analysis

Abstract

Measurements of the underwater polarized light field were performed at different stations, atmospheric conditions and water compositions using a newly developed hyperspectral and multiangular polarimeter during a recent cruise in the coastal areas of New York Harbor - Sandy Hook, NJ region (LISA). Results represented for waters with chlorophyll concentrations 1.3-4.8-micrometer g/1 and minerals concentrations 2.0- 3.9mg/1. Angular and spectral variations of the degree of polarization are found to be consistent with theory. Maximum values of the degree of polarization do not exceed 0.4 and the position of the maximum is close to 100" scattering angle. Normalized radiances and degrees of polarization are compared with simulated ones obtained with a Monte Carlo radiative transfer code for the atmosphere-ocean system and show satisfactory agreement.
