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 (USA). Results are presented for waters with chlorophyll concentrations 1.3-4.8 microg/l and minerals concentrations 2.0- 3.9 mg/l. 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 masculine 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.
在最近一次对美国新泽西州纽约港 - 桑迪胡克沿海地区的巡航期间，使用新开发的高光谱多角度偏振计在不同站点、大气条件和水体成分下进行了水下偏振光场测量。给出了叶绿素浓度为1.3 - 4.8微克/升、矿物质浓度为2.0 - 3.9毫克/升的水体的测量结果。偏振度的角度和光谱变化与理论一致。偏振度的最大值不超过0.4，且最大值位置接近100°的散射角。将归一化辐亮度和偏振度与使用大气 - 海洋系统的蒙特卡罗辐射传输代码获得的模拟值进行比较，结果显示出令人满意的一致性。
