Lidar Remote Sensing of Internal Waves and Optical Properties,
ARETE ASSOCIATES ENCINO CA
In this paper we summarize the theoretical basis and recent experimental results on the remote sensing capability of a lidar probing down into the ocean. The emphasis will be on the detection of modulations in the lidar return induced by the internal wave displacement field. The experiment included a high precision lidar operated through a plexiglass window flush with the keel of a drifting ship. Internal waves were measured simultaneously and nearly coincidentally with a chain of thermistors. Measured ocean optical properties included vertical profiles of beam attenuation coefficient, spectra diffuse attenuation coefficient, point spread function and local particulate backscattering versus time at several depths. Coherences between the lidar return at various depths and internal wave displacements have been determined for several blocks of data and indicate detections of internal wave induced modulations in the lidar return.
