The Antarctic Circumpolar Current moves perpetually eastward – chasing and joining itself, and at 21,000 km (13,000 mi) in length – it comprises the world's longest ocean current, transporting 130 million cubic metres per second (4.6 × 10 ^ 9 cu ft/s) of water – 100 times the flow of all the world's rivers.

The ACC, as it encircles the Antarctic continent, flows eastward through the southern portions of the Atlantic, Indian, and Pacific Oceans. Dynamics of Pacific Antarctic Circumpolar Current (DYNAPACC) Dynamics of Pacific Antarctic Circumpolar Current (DYNAPACC) International Ocean Discovery Program Expedition 383. Please refer to the appropriate style manual or other sources if you have any questions. Warm, subtropical surface currents in the Atlantic, Pacific, and Indian oceans move southward in the western parts of these waters and then turn eastward upon meeting the Circumpolar Current. The volume of transport south of latitude 40° S is thought to be at least 25,000,000 cubic m (880,000,000 cubic feet) per second. //. . ." Affected by adjacent landmasses, submarine topography, and prevailing winds, the Antarctic Circumpolar Current is irregular in width and course. Despite its potential importance for shaping biogeographical patterns, the distribution and connectivity of deep-sea populations across the ACC remain poorly understood. Some of the most rapid melting of ice sheets and ice shelves around Antarctica has occurred where the Antarctic Circumpolar Current (ACC) is in close proximity to the Antarctic continent.

Antarctica is surrounded by the Antarctic Circumpolar Current (ACC), the largest and strongest current in the world. (March 17, 2021). The Antarctic Circumpolar Current is not a well-defined single-axis current but rather consists of a series of individual currents separated by frontal zones. Encyclopedia.com. Its motion is further complicated by continuous exchange with other water masses at all depths. This current is the counter-current of the largest ocean current in the world, Antarctic Circumpolar Current.On the average, it flows westward and parallel to the Antarctic coastline. Then, copy and paste the text into your bibliography or works cited list. The Circumpolar Current circles Antarctica clockwise from west to east, speeding ships flowing with the current but providing resistance for those sailing in the opposite direction. ." The Antarctic Circumpolar Current could not have developed until later. The connectivity of AABW between the Antarctic continental shelf and the northern basins is mediated by the Antarctic Circumpolar Current (ACC), a circumpolar eastward flow that also serves as the primary route for inter-basin exchange. ." 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 1986; Olbers et al. It reaches the seafloor and is guided along its course by the irregular bottom topography. Most importantly, the lack of continental boundaries in the east–west direction means that circumpolar flow is uninterrupted, leading to continuous eastward flow. The warm water meets and partly mixes with cold Antarctic water, called the Antarctic…. 1) is constantly accelerated by the eastward wind stress … Our editors will review what you’ve submitted and determine whether to revise the article. https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/west-wind-drift, AILSA ALLABY and MICHAEL ALLABY "West Wind Drift In this belt flows the, …the West Wind Drift, or Circumpolar Current. ."
