Abstract
The inversion of the optical contrasts between the ripple and slick areas created by natural processes is analyzed. It is shown that, depending on the solar zenith angle and the angle at which spacecraft-mounted optical scanner observes the slick-ripple areas border, the intensity of light reflected from the slick area may be either greater or less than the intensity of light reflected from the ripple area. The quantitative evaluations of the sea surface slopes corresponding to inversion of the slick-ripple areas optical contrast are obtained.
