On the effect of sun altitude on the horizontal distribution of natural light underwater

Abstract

SIO Reference 60-17. Skylighting which is symmetrical about the zenith generates a light vector diagram which is symmetrical about the vertical axis. When the sun departs from a position of symmetry the light vector diagrams become distorted. The extent of this distortion can to some extent be predicted from a knowledge of the scattering and reflecting properties of the water. The method of prediction is explained.
