Diffusive transport of light in sea ice.
A new experimental technique has been developed and tested in McMurdo Sound, Antarctica for the in situ measurement of the diffusive transport of light through sea ice. A weakly divergent monochromatic light source is placed on the surface of the ice, and the emergent radiation field is measured at both the top and bottom surfaces. The spatial and angular distribution of the emergent radiance, combined with the results of Monte Carlo simulations, has given a simple and direct measurement of the light scattering length, inhomogeneity, and anisotropy in this very complex material.
