Description
Summary:This paper presents the NRL shipboard lidar and the first lidar dataset of underwater bubbles. The meaning of these lidar observations, the algorithms used and their current limitations are discussed. The derivation of the lidar multiple scattering regime is derived from the lidar observations and theory. The detection of the underwater bubble presence and their depth is straightforward to estimate from the depolarized laser return. This dataset strongly suggest that the whitecaps term in the lidar equation formalism needs to be revisited. Void fraction retrieval is possible and the algorithm is stable with a simple ocean backscatter lidar system. The accuracy of the void fraction retrieval will increase significantly with future developments.
