Professional interests

The area of scientific interests is the study of the circulation of the waters of the World Ocean, the study of the large-scale structure and dynamics of the waters of the World Ocean, especially its deep and bottom layers. Many scientific works are devoted to the study of the long-term variability of the properties and dynamics of ocean waters in the context of modern climatic changes.

Main research results

The first cycle of works was devoted to the study of the structure and dynamics of the deep and bottom layers of the eastern part of the tropical zone of the Pacific Ocean, the development of the instrument base for measuring the bottom currents. The work was carried out within the framework of the Abyssal project and was aimed at hydrometeorological support for the proposed mining of ferromanganese nodules in the Clarion and Clipperton fault zones. As a result of comprehensive studies of the entire water column at the test site in the North-Eastern Pacific Basin, the presence of eddies penetrating to the bottom was recorded, which are the cause of anomalies in the structure and dynamics of the deep and bottom layers, including benthic storms.

The second cycle of works is devoted to the study of the variability of the large-scale structure and dynamics of the waters of the North Atlantic and its interaction with the global convective meridional circulation of the World Ocean.

During participation in the implementation of the international WOCE program, the reason for the multidirectional trends in the variability of the thermohaline structure of the waters of the subpolar and subtropical North Atlantic was revealed. Based on the calculation of water transport, the circulation schemes of the surface, intermediate, deep and bottom layers of the North Atlantic were constructed for three decades (1950s, 1980s and 1990s). The existence of two modes of global convective meridional circulation in the North Atlantic during this period has been established. The mechanisms responsible for the change in the meridional circulation regimes have been identified. It was found that the intensification of the meridional circulation is in antiphase with the intensity of the formation of Labrador waters.

A.V. Sokov is the author of over 100 scientific papers published in leading peer-reviewed Russian and foreign scientific journals. He was engaged in the organization and conduct of large expeditions to study the World Ocean, he is a member of 32 expeditions in the Pacific and Atlantic oceans, most of which were planned and organized under his leadership within the framework of the Abyssal, Meridian projects and the international programs WOCE and CLIVAR.
