The Prediction of Diver Visibility and Its Relation to Spectral Beam Attenuation

The goal of the proposed research is to determine the dependence of a simple diver visibility parameter (horizontal visibility of a black disk)on the spectral beam attenuation coefficient. In particular we will investigate whether the beam attenuation coefficient at a single wavelength can be used t...

Description
Summary:The goal of the proposed research is to determine the dependence of a simple diver visibility parameter (horizontal visibility of a black disk)on the spectral beam attenuation coefficient. In particular we will investigate whether the beam attenuation coefficient at a single wavelength can be used to predict visibility or whether accurate prediction requires spectral attenuation measurements.
