The use of the geoelectrochemical method of ion-selective electrodes for continuous recording of hydrocarbon micro-components – heavy metals – during the vessel movement to search for oil and gas deposits on the shelf is justified theoretically and experimentally. The existence of «jet» halos in the water column above the shelf oil and gas deposits is discovered experimentally and the method of geoelectrochemical ion-selective electrodes as well as the developed instrumentation for recording these halos is described. The application of a new geoelectrochemical method for prospecting in motion (without sampling) both structural and non-structural oil and gas deposits on the shelf is justified.
In article scientifically – theoretical representations about geoecological researches on a shelf are stated, the purpose and tasks in view of works the conditions of a bottom geoecosystem directed on an estimation is offered. Classification of sources of receipt of polluting substances in a marine geoecosystem is resulted. The group of sources is in more details characterized endogenetic, the methodology of researches is stated and the technology of works is offered.
