Abstract

A method of investigation sea surface roughness by analysis polarization images is suggested. Equipment and software were developed and tested at the Pacific Oceanological Institute (POI) It is shown a possibility to study surface manifestations of hydrodynamic processes in coastal zone, such as the dynamics of vortex structures, internal waves, spatio-temporal properties of surface waves by using the panoramic video system for a sea surface control and by the imaging polarimeter. Analysis of a time sequence of transformed to the plane panoramic images obtained using the system allows to estimate a velocity field of vortex structure, phase velocity of surface manifestations of internal waves, intensity and dynamics of surface films of oil pollution. It is shown an ability of sea surface reconstruction by analyzing time sequence of the imaging polarimeter pictures. The results are compared with the height difference of the floats located on the vertical guides that are in the imaging polarimeter field of view. The float heights obtained from its image coordinates. Field experiments were conducted at the POI marine station in the Japan Sea. Moreover, the developed methods and equipment may be used as a source of unique in situ information on the sea surface roughness during satellite optical and radar sensing.
