The organic films form a brightness contrast on the sea surface. It makes possible to use cheap simple and miniature systems for video monitoring of pollution of coastal marine areas by oil products in the bunkering of ships, emergency situations at oil terminals, gas and oil pipelines, hydrocarbon production platforms on the shelf, etc.1-16 A panoramic video system with a polarization filter on the lens, located at an altitude of 90 m above sea level, can provide effective control of the water area within a radius of 7 kilometers,17-19 and modern photogrammetry technologies allow not only to register the fact of pollution and get a portrait of the offender, but also with a high Spatial and temporal resolution to estimate the dimensions and trace the dynamics of movement and transformation of the film in a geographic coordinate system. Of particular relevance is the optical method of controlling the pollution of the sea surface at the present time with the development of unmanned aerial vehicles that are already equipped with video cameras and require only a minor upgrade of their video system to enhance the contrast of images of organic films.
In this paper we present a new measurement tool - polarimeter, based on video matrix. Polarimetric measure- ments are usefull, for example, when monitoring water areas pollutions and atmosphere constituents. New device is small enough to mount on unmanned aircraft vehicles (quadrocopters) and stationary platforms. Device and corresponding software turns it into real-time monitoring system, that helps to solve some research problems.
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.
The results of comparisons of chlorophyll (alpha) concentrations, measured using different methods in various regions of the Ocean, are presented. The data measured simultaneously by remote sensing (SeaWiFS, CZCS) and from the moving ship using of the laser induced fluorescence, spectrometer for measuring of the spectral distribution of the upwelling radiation and standard absorption method were analyzed.
