It is well known that film slicks on the sea surface can reflect various geophysical processes in the upper layer of the ocean and in the atmosphere. Banded slick structures that appear on SAR images of the sea surface at low and moderate wind speeds are usually associated with sea currents. This paper presents the results of the first experiments to study the dynamics of an artificial slick band in the field of marine current and wind. It is shown that the contribution of wind to the propagation of a slick band can be significant, and at certain stages of the band dynamics the influence of spreading effects can be neglected. For these quasi-stationary sections of the slick band an empirical relationship between the band width and the surface velocity is obtained. An advantage of the proposed approach is based on the possibility of obtaining the spatial structure of the surface velocity along a slick band accor­ding to the information regarding the band shape and hydrometeorological measurements at any section of it. The approach may be effective in verifying remote sensing data.
Keywords: marine currents, slick band, sea surface, surfactants
