RADIANCE DISTRIBUTION AS A FUNCTION OF DEPTH IN THE SUBMARINE ENVIRONMENT
Abstract
A theoretical treatment of natural underwater light based on isotropic scattering was made. Observations were made on clear sunny days and compared with observ tions on overcast day . Observations were also made at various depths and through various color filters. The light field was explored in a vertical plane in the sun's direction and in the vertical plane at right angles to the sun's direction. In addition the light field was explored at azimut weeps taken at various zenith angles. It was observed that the angular distribution pattern of the natural light field changed in shape with depth and it was surmised that at some unknown depth an equilibrium shap might be reached. It was also noted that the direction of the bright spot in the submarine light field tended to approach the zenith as depth was increased. Although the data was adequate for the intended purpose.
