Natural factors, technical means for remote monitoring and methodology for interpreting remote sensing images are discussed. Natural factors that determine the monitoring conditions include hydrometeorological regime, topography, soil, and thickets of submerged aquatic vegetation. Submarine topographical features, soils and associated seabed biocenoses form regular combinations that make the base of morphological landscape units (submarine landforms and facies). The latter, having specific physiognomic features, serve as the main target of photography in airborne and satellite images.
The technique for remote monitoring the shallow seabed involves the use of equipment installed on aircraft, unmanned airborne vehicles (UAVs) and satellites; shipborne ultrasonic (sonar) survey is a special type of monitoring.
The fundamentals of the methodology for using remote sensing images were developed on the basis of interpreting large-scale airborne photographs of the shallow seabed.
The landscape method of image interpretation is based on the use of regular relationships between components of environment: through the identification and characteristics of targets appearing in the images, a logical conclusion is made about the presence and properties of objects and phenomena that are not directly displayed in the images, but associated with them via natural connections. There are the laboratory stage, submarine studies, and extrapolation of interpreting features. Elementary airborne photographic standards are fragments from airborne photographs, which characterize images of seabed nature complexes (SNC) of key areas. Standards are used to extrapolate interpreting features to images of the same type. The inter-landscape extrapolation is performed by studying analogous landscapes and transferring the established interpreting features to unvisited water areas.
In conclusion, a programme of comprehensive landscape-bionomic studies is proposed. Remote monitoring and mapping of the shallow seabed based on the proposed programme will ensure uniformity of work and comparability of the results obtained.
