OBSERVATIONS OF LIGHT SCATTERING IN SEA WATER.

Abstract

Combination of theoretical curves of the volume scattering function for several different monodisperse systems of Mie scatterers shows that in a polydisperse system the total scattering coefficient is determined by the scattering at small angles to the direction of the incident beam. These combined curves also show that as the particle sizes increase the rise in the volume scattering function at small angles increases. Using a laser as the light source, forward scattering measurements were made to obtain relative total scattering. A continuous track was made between Woods Hole and Port Lewis, Mauritius. In the proximity of land twofold fluctuations of the scattering in a range approximately three times higher than the nearly constant values found in mid-Atlantic were observed. Some fluctuations of the open sea values in the Atlantic were associated with thermal changes.
