Physical Bases of Modern Low-Frequency Technologies of Remote Monitoring of Objects of Sea Biosphere and their Theoretical Explanations

The paper presents the rezults of the theoretical investigations of physical models and techological solutions that explain the process of interaction of low-frequensy signals with physical phenomena and objects in the ocean environment. The models under study are being used for a large-scale scientific monitoring of the ocean environment aimed at selection of the physical parameters for the spatial detection of the physical phenomena.
