The world ocean is an integral system, directly influencing the climate of the whole planet, the plant and the animal world, the processes of life and human activity. The result of the World Ocean space, its waters and resources intensive use is the problem of its protection against pollution. It is one of the new challenges and threats to the security of states. Nevertheless, of all natural objects, this most important component of the Earth hydrosphere is most exposed to pollution. Thus, according to expert estimates, most of the total amount of the world ocean pollution is conditioned by terrestrial sources, which are the least manageable by international law due to their location on the territory of a certain sovereign state. Coastal areas are exploited by a man very actively and bring the greatest economic benefit. And, thus, this zone is the center of the greatest anthropogenic impact on the waters and the living resources of the World Ocean. Entering the coastal marine areas located on the shores of industrialized countries, the amount of pollutants is so high that it can rightly be considered as a global environmental problem of an international character with a rapid movement and distribution, capable to predetermine the fate of the entire oceans. Therefore, it is quite natural that from the middle of the twentieth century this problem became a key issue for states, academic circles, international specialists and put them before the need to develop a mechanism for its international legal and national regulation as soon as possible.

Kazakhstan’s economic policy results in 1995-2005 are considered in the article. In particular, the analysis of the relationship between economic growth and some indicators of nation states - population, territory, direct access to the World Ocean, and extraction of crude petroleum - is presented. Basic problems in the sphere of economic policy in Kazakhstan are formulated.

The main content of the work consists of certain systematization and addition of longexisting, but eventually deformed and partly lost qualitative ideas about the role of thermal and wind factors that determine the physical mechanism of the World Ocean’s General Circulation System (OGCS). It is noted that the conceptual foundations of the theory of the OGCS in one form or another are contained in the works of many well-known hydrophysicists of the last century, but the aggregate, logically coherent description of the key factors determining the physical model of the OGCS in the public literature is not so easy to find. An attempt is made to clarify and concretize some general ideas about the two key blocks that form the basis of an adequate physical model of the system of oceanic water masses motion in a climatic scale. Attention is drawn to the fact that when analyzing the OGCS it is necessary to take into account not only immediate but also indirect effects of thermal and wind factors on the ocean surface. In conclusion, it is noted that, in the end, by the uneven flow of heat to the surface of the ocean can be explained the nature of both external and almost all internal factors, in one way or another contributing to the excitation of the general, or climatic, ocean circulation.

The study is devoted to the analysis of the features of the change in the Equivalent Water Height (EWH) parameter over the geoid based on satellite measurements of space systems. The study used the GRACE and GRACE-FO satellite data archive. The assessment was carried out on Earth as a whole, including land areas and the World Ocean. Interpretation of the anomalous state of the geoenvironment is performed using digital maps of the spatial distribution of the EWH parameter based on the histogram approach and correlation analysis. Also, a comparative analysis of the studied data from the GRACE mission and data from the new GRACE-FO satellite system launched into orbit in the summer of 2018 was carried out.
