The concept of a bilayer hydrosphere: From the origins to the methodological approaches

Abstract

This paper considers the results of development of the bilayer hydrosphere concept of the Earth offered by the author in 2000. The bilayering concept is logically based on the classical works in the field of geochemistry and is in the context of mid-twentieth century studies on the structure of the biosphere. The research methods based on this concept are interdisciplinary in nature and make it possible to unify and thereby to facilitate the solution of many problems in the field of oceanology, hydrology and other geographic sciences related to geochemistry.
