Abstract

An apparatus has been constructed that allows the underwater marine light field to be physically simulated using artificial light sources and optical components. The arrangement of components allows downwelling, sidewelling, and upwelling marine light to be recreated in its measured or theoretically determined spectral and polarized structure. The design of an apparatus of this type takes into account a generalized set of simulation categories called simulation regimes. The visual parameters of the animal to be studied, the optical nature of the water to be simulated, and the depth in the water column selected, define a particular simulation regime categgry through the underwater contrast-visual range equation of Duntley and the geometrical criteria defined in this paper. This work seeks to provide researchers with a means of investigating marine animal behaviors that utilize specific aspects of the spectral and polarized structure of marine light. Initial results of experiments performed with the apparatus, involving a marine crustacean, are given to demonstrate the use and range of application of the apparatus.
