The long-term goals of this project are as follows 1 develop instruments to measure the near-pi backscattering properties of particles in the near-pi region, 2 quantify and understand the inherent optical properties of natural particles with a particular emphasis on polarization, and 3 present the results in a manner useful to the optics community. The scientific objectives of the project are to modify the LISST-Back near-pi backscatter measuring instrument to add polarization measurement capabilities, characterize and contrast natural particle scattering with scattering by spheres, and publish the observed properties in a manner accessible to the optics community. This work has relevance to interpreting LIDAR measurements of scattering from the coastal seas. The idea is to advance knowledge of backscattering cross-sections and the polarization properties of particles. The following work has been completed the addition of polarization capability to the LISST-Back instrument, the development of a new method to measure spherical particle size, the comparison of backscattering of spheres with the backscattering of randomly shaped grains, and field observations of backscattering of marine particles.
