A shipboard ocean lidar system, whose wavelength is 532 nm produced by a frequency doubled Nd∶YAG laser, was developed for measuring the concentration of ocean suspended matter. The Lidar system was installed on research vessel Dongfanghong Ⅱ, and the Lidar measurements of ocean suspended matter were conducted in Bohai Bay from August 28 to September 5, 2000. The concentrations of suspended matter were obtained at 18 sites by the Lidar. The results of Lidar measurements are in agreement with the that from in situ simultaneous sampling.
