As a new interdisciplinary science of oceanography and geography, the marine Geography studies include: the exploitation and protection of ocean environment and resources; marine economy; ocean policy; marine regulation and ocean management; the application and resources of marine sciences and new technology; etc. The third UN Conference on the Law of the Sea (1982) started the processes of revolutionary changes in the role of national jurisdictional zones in ocean management, creating two entirely new zones: the exclusive economic zone (EEZ), archipelagic states and waters, and introducing significant changes to the regimes of the continental shelf and of passage through straits. The coastal countries are thus confronted with greatly expanded ocean space. As a result, marine geography has been grown rapidly since 1980’s. The state of the art concerning the global change is assessed from the dominant development perspective which is party cyclical in the nature, with assessment of the significance of the traditional society, and the concepts of interrelated environment and human global change mechanism. Practical aspects emphasise the primacy of interaction between man and the sea which is the basis upon the technical management system.
