The article commemorates the 90th anniversary of Prof. M.N. Koshlyakov – prominent scientific figure of the Russian Federation, physical oceanographer, recipient of the Makarov’s Prize, Doctor of Physical and Mathematical Sciences, Honored Professor of the Moscow Institute of Physics and Technology. He is Chief Scientist, the founder and the first Head of the Laboratory of Marine Currents at the P.P. Shirshov Institute of Oceanology of the Russian Academy of Sciences. Prof. Koshlyakov made major contributions to studies of temporal and spatial variability of oceanographic variables over a broad range of scales. Over his career, he participated and led over two dozen scientific expeditions, including such large ocean projects as Polygon–67, Polygon–70, POLYMODE, MEGAPOLYGON, ATLANTEX–90. His expeditions extended to regions of the western boundary currents of the Atlantic, Indian, and Pacific Oceans, to observe new, previously unknown components of the circulation of the World Ocean waters. Prof. Koshlyakov is the lead author of the discovery of open ocean mesoscale eddies made by a team of oceanographers at the Institute of Oceanology at the turn of the 1960–1970s. This discovery became a milestone in oceanography of the 20th century that dramatically changed our understanding of the processes governing the Ocean and their influence on the Earth’s climate. From mid-1960s to early 1990s, Prof. Koshlyakov was a direct participant and subsequently the leader of the main domestic and international experiments on the study of ocean eddies.

Conceptual Foundations

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.

This year in 2021, Shirshov Institute of Oceanology celebrated 75 years old. Shirshov Institute is the largest and oldest research center of seas and oceans in Russia. In the past and present of the Institute, there are many significant discoveries and developments for world oceanology, the most complex expeditions and large-scale international projects. I am sure that our future as a Center for the Study of the World Ocean will be no less rich and bright.

Shirshov Institute of Oceanology of the Russian Academy of Sciences, DSc, ex-president of the International Association for Physical Ocean Sciences (IAPSO) Evgeny Morozov is 75 years old. E.G. Morozov is a prominent scientist and organizer of world-class science in the field of studying the temporal and spatial variability of hydrological processes and internal waves in a wide range of scales. He was the first to build a map of the amplitudes of tidal internal waves of the World Ocean. His monograph “Oceanic Internal Waves” published in 1985 in Russian, as well as his article “Semidiurnal internal wave global field”, published in the Deep Sea Research in 1995, are among the most cited on the problem of internal tidal waves. Unique results were obtained by E.G. Morozov in the study of internal waves in the Arctic, including under the ice and near the front of glaciers sliding into the ocean on Spitsbergen. He made a significant contribution to the study of various currents: the Gulf Stream, the Kuroshio and their rings, the Antarctic Circumpolar Current, the California Current, the Falkland Current, the Lomonosov and Tareev subsurface equatorial currents. Since 1999 he has been a member of the Executive Committee of the International Association for the Physical Sciences of the Ocean (IAPSO) and since 2011 he has been elected President of the IAPSO, represented the IAPSO in this capacity on the Executive Committee of the International Geodetic and Geophysical Union (IUGG) and on the Executive Committee of the Scientific Committee on Oceanic research (SCOR). E.G. Morozov is the chairman of the Ocean Physical Sciences Section of the National Geophysical Committee of the Russian Academy of Sciences.

The Impact

<p>Quantifying meltwater content and describing transport pathways is important for understanding the impact of a warming, melting Antarctica on ocean circulation. Meltwater fluxes can affect density-driven, on-shelf flows around the continent, and the formation of the dense water masses that ventilate abyssal regions of the world ocean. We present observations collected from two ocean gliders that were deployed in the Bellingshausen Sea for a period of 10 weeks between January and March of 2020.<span>  </span>Using multiple high-resolution sections, we quantify both the distribution of meltwater concentrations and lateral meltwater fluxes within the Belgica Trough in the Bellingshausen Sea. We observe a cyclonic circulation in the trough, in agreement with previous studies. A meltwater flux of 0.46 mSv is observed flowing northwards in the<span>  </span>western limb of the cyclonic circulation. A newly identified meltwater re-circulation (0.88 mSv) is observed flowing back towards the ice front (i.e. southwards) with the eastern limb of the cyclonic circulation. In addition, 1.16 mSv of meltwater is observed flowing northeastward, parallel to the shelf break, with the northern limb of the cyclonic circulation. Peak meltwater is concentrated into two layers associated with different density surfaces: one approximately 150 m deep (27.4 kg m<sup>-3</sup>) and one approximately 200 m deep (27.6 kg m<sup>-3</sup>}). The deeper of these layers is characterised by an elevated optical backscatter, which indicates a more turbid water mass. The shallower layer is less turbid, and is more prominent closer to the shelf break and in the eastern part of the Belgica Trough. We hypothesise that the deeper, turbid meltwater layer originates locally from the Venables Ice Shelf, whereas the shallower, less turbid meltwater layer, comprises meltwater from ice shelves in the eastern Bellingshausen Sea. The broad distribution of meltwater from multiple sources suggests the potential for remote interactions and feedbacks between the various ice shelves that abut the Bellingshausen Sea.</p>
