System (complex) for optical monitoring of coastal marine water areas: concept and methods

The concept of a system for continuous express monitoring of coastal sea water areas is presented. According to the suggested concept, the monitoring system should consist, in general, of three parts, in which the key role should belong to laser devices: (a) shore-based lidar that performs continuous monitoring of water surface and sub-surface layer of water (and, possibly, of atmosphere) in the selected water area; (b) patrol boat equipped dth submerged portable devices, including laser spectrometer with submerged optical fiber probe; (c) coastal laboratory equipped with devices for detailed (but ex-press enough) analysis of water samples, specially chosen by the results of remote laser sensing and submerged device data. Some features of remote sensing by means of shore-based lidar are considered. The main feature is sliding incidence of laser beam to water surface. The coastal sea waters have much more complex and variable composition than open sea water. The possibilities of different versions of laser fluorimetry in diagnostics of organic compounds in coastal sea waters are analysed.
