Airborne estimation of sea turbidity parameters from the WRELADS laser airborne depth sounder.

Techniques are presented for the estimation of the optical attenuation coefficient and a backscatter parameter that is proportional to the optical backscatter coefficient from data collected from a laser-based airborne hydrographic system. The validity of two such techniques is discussed in light of substantial amounts of data that have been collected using the WRELADS airborne depth sounder. The data collected demonstrate a number of different functional relationships linking attenuation to backscatter in adjacent bodies of water. It also demonstrates the capability of using such airborne techniques for detection, mapping, and monitoring of unusual turbidity features within the ocean.
