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 in situ dataset used in the current study consists of the Pacific Current Meter 3 (PCM3) array, which was a significant part of the Australian contribution to the World Ocean Circulation Experiment to study the variability of the East Australian Current (EAC), and was operational between September 1991 and March 1994. Area-preserving spectral analysis has been used to investigate the typical time scales observed by the current meters. As a general rule, the spectra from the top layers of the shallow (1, 2 and 3) and the deep (4, 5 and 6) moorings have a distinct peak in the temporal mesoscale band (periods between 70 and 170 days), with a general redistribution of energy towards the higher-frequencies near the ocean floor. This peak has been linked with eddy variability of the EAC system, which influences the fluctuations of the current main jet. The vertical modes of the velocity profile show that the strong surface-intensified baroclinic signal of the EAC dominated the variability at mooring 4 location. Further offshore the predominant configuration resembles more closely the barotropic mode. Ultimately, spatial empirical orthogonal functions (EOF) analysis point out the impact of the presence/absence of the EAC jet in the array.

Though Russia, in contrast with England, had no broad access to the oceans, Russian oceanographers always took a great interest in the world ocean investigations. To confirm this we would first of all like to mention the Russian cruises around the world, made by I. F. Krusenstern and Ju. F. Lisjansky in 1803–06, V. M. Golovnin in 1806–13 and 1817–19, M. P. Lazarev in 1819–21 and 1822–25 (the second voyage, the main result of which was the discovery of the Antarctic Continent, was made together with F. F. Bellingshauzen), O. E. Kotsebu in 1815–18 and 1823–26, and F. O. Litke in 1826–29. The names of several Russian explorers who carried on important work in various parts of the Arctic and the Pacific Oceans in different periods of the nineteenth century are well known. At one time valuable results of the oceanological investigations, carried out by Admiral S. O. Makarov on the ship Vitjaz in the Pacific Ocean in 1886–89, attracted much attention. The fact that Vitjaz is lettered on the pediment of the Oceanographical Museum of Monaco among the ten ships most distinguished in oceanographical explorations from the whole world testifies to the scientific importance of Makarov's investigations.
