Abstract

Contrast transmittance (CT) theory has been used to derive a simple two-parameter visibility model that has been used by the civilian and military sectors for over seventy years. We review this classical theory with special attention to its application to problems in estimating liminal visibility range for in-water divers. Previous work by Duntley of the MIT/SIO Visibility Lab states that calculations based on this simple model give reasonable agreement with observation provided all embedded assumptions hold. Recent dat form divers conducting shallow water observations indicate that these assumptions cause the model to give poor results in this domain. We investigate an enhanced method that eliminates some of these assumptions to provide better estimate of underwater diver visibility.
