Introduction [2] In the first part of this two‐part study [Sokolov and Rintoul, , hereinafter SR], we demonstrated that the Antarctic Circumpolar Current (ACC) consists of multiple jets aligned along particular streamlines throughout the circumpolar path of the ACC frontal structure inferred from maps of sea surface height (SSH) was shown to be consistent Cited by: Request PDF | Circumpolar structure and distribution of the Antarctic Circumpolar Current fronts: 2.

[1] In Part 1 of this study, we showed that the Antarctic Circumpolar Current (ACC) consisted of multiple fronts, each of which was consistently associated with a particular contour of sea surface height (SSH) or approximate streamline. In Part 2 we have used maps of SSH to examine the variability of the ACC fronts between and The SSH label associated with each frontal branch is.

The spatiotemporal variability of the Antarctic Circumpolar Current (ACC) structure in the upper – m layer is analyzed at two sections in the Drake Passage. The existence of the Subantarctic and Polar Current superjets, formed due to the confluence of a few jets together, is confirmed. Peak eddy activity at the periphery of all the ACC jets is revealed, which demonstates intensive. The Antarctic Circumpolar Current (ACC) is strongly wind forced, ACC must negotiate a number of large topographic barriers, and the meridional deflection of the current influences its structure and variability. Along the ACC pathway, we can define three categories of flow for the SAF and the PF. These are merging, shoaling, and strong. The Antarctic Circumpolar Current (ACC) is the most important current in the Southern Ocean, and the only current that flows completely around the globe. The ACC, as it encircles the Antarctic continent, flows eastward through the southern portions of the Atlantic, Indian, and Pacific Oceans. E.I., Structure and Variability of the. by the presence of a strong eastward, circumpolar cur-rent, the Antarctic Circumpolar Current. The ACC connects the three major ocean basins (Atlantic, Pa-cific, and Indian) and redistributes active and passive oceanic tracers such as heat, salt, and nutrients. .

structure and transport of the ACC (Section ). Numerical and analytical models have led to sub-stantial advances with regard to the theory and dynamics of the ACC, and its links to the merid-ional circulation (Section ). New observations The Antarctic Circumpolar Current System Rintoul,Hughes and Olbers 60 50 40   Connecting the major Southern Hemisphere oceans, the Antarctic circumpolar current (ACC) plays a decisive role in the mid- to high-latitude SH climate and its variability (e.g., Nowlin and Klinck ; Olbers et al. ).The ACC is an eastward geostrophic flow manifesting as a zonal circulation (clockwise when viewed from above Antarctica) typically in the form of series of fronts and.   Southern Ocean warming is concentrated in the circumpolar band corresponding to the Antarctic Circumpolar Current (ACC). In the top m of the ocean, approximately 80% of the net heat content increase in the Southern Hemisphere oceans appears to have occurred south of 30° S, largely within the ACC [ 2 ].   South Georgia, an island in the eastern Scotia Sea [∼54°S, 37°W; Fig. 1(a)], experiences dramatic interannual variability in its variability is connected to fluctuations in the local abundance of Antarctic krill (Euphausia superba), the main food source of the higher predators that breed on South Georgia Croxall et al., , Croxall et al., , Boyd et al.,
