Abstract:

Time and space dependent radiance distributions at the sea surface are a function of the shape of the incident distribution on the surface, modification by the sea surface itself from topography and transmission characteristics, and alteration by the Inherent Optical Properties IOPs of the surface ocean. The long term goal of the proposed work is understanding this last controlling factor. With a knowledge of the IOPs, radiance fields can be directly computed from the incident field using the equation of radiative transfer, now embedded in commercially available code e.g., Hydrolight. With the state of current technology and methodologies, the primary obstacles in understanding subsurface IOPs and their high-frequency dynamics are a lack of 1 volume scattering instrumentation, 2 comprehensive inversion models linking the IOPs with the causative bubble, particulate, and dissolved matter in the water which in many cases will require input dependent on 1, and 3 suitably stable, non-intrusive platforms to sample the subsurface ocean. The first two challenges are addressed in this project.
