The airborne lidar detection and cross-sectional mapping of submerged oceanic scattering layers are reported. The field experiment was conducted in the Atlantic Ocean southeast of Assateague Island, VA. NASA's Airborne Oceanographic Lidar was operated in the bathymetric mode to acquire on-wavelength 532-nm depth-resolved backscatter signals from shelf/slope waters. Unwanted laser pulse reflection from the airwater interface was minimized by spatial filtering and off-nadir operation. The presence of thermal stratification over the shelf was verified by the deployment of airborne expendable bathythermographs. Optical beam transmission measurements acquired from a surface truthing vessel indicated the presence of a layer of turbid water near the sea floor over the inner portion of the shelf.
报道了机载激光雷达对水下海洋散射层的探测及剖面测绘。实地实验在弗吉尼亚州阿萨蒂格岛东南部的大西洋进行。美国国家航空航天局的机载海洋学激光雷达以测深模式运行，以获取来自陆架/陆坡水域的波长为532纳米的深度分辨后向散射信号。通过空间滤波和离天底操作，将来自气水界面的有害激光脉冲反射降至最低。通过部署机载一次性温深仪，验证了陆架上存在热分层现象。从一艘地面实况测量船获取的光束透射测量结果表明，在陆架内部靠近海底处存在一层浑浊水体。
