Abstract

In theory, depth profiles of received power from ocean remote sensing airborne lidar data with a wide filed of view can be related to the diffuse attenuation coefficient, K_d. Preliminary results from clear open ocean waters in the Sargasso Sea and in the North Pacific Ocean indicate that a wavelength dependent discrepancy may exist, and that the 532 nm lidar K_d values are approximately 33 percent lower values than those derived from sunlight. If the discrepancies can be resolved, then a lidar system could provide a way to remotely measure the spatial variability of K_d over synoptic scales that can not be achieved within a reasonable time interval from a surface vessel.
