Lidar Measurements of Ocean Optical Properties in Tank Tests and Coastal Water With Model Simulation Closure
A dual wavelength, monostatic underwater profiling lidar system has been developed at Harbor Branch that has now been rigorously characterized in laboratory tank tests and the field. Lidar performance has additionally been simulated through Monte-Carlo modeling. Tank tests were conducted to demonstrate closure between measurements and modeling for two carefully characterized particle fields with significantly different scattering properties. Measurements were also made off the coast of Florida along with water column optical property measurements to assess closure with simulations. Relationships between lidar data and in water optical properties is assessed for all measurements and for simulated optical property data for a wide range of water types. Results show good closure and the potential of lidar as a next generation tool in oceanography.
