Laser Transmission Studies of East Coast Waters.

Abstract

The transmission of a blue-green laser through waters representing several sites on the east coast of the United States were studied in the laboratory. The primary purpose of this investigation is to establish the capability of an airborne laser-detector system. Scattering/ transmission distributions of a collimated beam of light were measured in waters in which the turbidity was adjusted by a specific sediment. The turbidity of the waters was characterized by an attenuation coefficient which ranged from 0.07-2.0/m and an a/s ratio of 0.08 - 0.30. The reflectivity of the various sediments ranged from 2-20%. The results of the alpha/sediment loading data obtained for the various sediments show a close agreement with the results obtained for quartz. (Author)
