Remote Sensing: Environmental Effects of Surface Films.
Abstract
This report describes a portion of a program involving both experimental and theoretical studies of the influences of natural biogenic sea surface films on air-sea interfacial parameters. In addition, the role of physical processes in the marine environment on the film's state and transport was investigated. Initial objectives included the determination of the effects of (1) currents on film formation and intensity, (2) surface films on waves, (3) surface films on wave/current interactions, and (4) surface films on near- surface turbulence. During the planning phase of the program these objectives were refined to emphasize the following specific subject areas: (1) Film transport and modulation by currents; (2) Surface-film influences on capillary waves for surface film concentrations and strain rates appropriate to surface effects of ocean internal waves; and (3) Determination of the effect of surface films on the wind-wave relaxation rate (beta) by direct measurement at wavelengths of interest to microwave radar imaging.
