Abstract

The study of marine areas in order to replenish the raw material base with additional sources is an increasingly relevant task. The modern geological exploration equipment development for the offshore deposits search requires a further study of both the deposits features and the seawater characteristics. According to the results of the existing offshore deposits analyzed data, it was revealed that the deposits are characterized by an increased content of hydrocarbon gas bubbles on the surface of the water, as well as an increased content of these substances in the waters themselves. The main indicator substances were determined to be watersoluble methane, propane, ethane and butane. In addition, the paper presents the results of the vertical distribution of these substances modeling over marine deposits
