Detailed explanation-1: -Its main oceanographic feature, the Antarctic Circumpolar Current (ACC), is the world’s only global current, flowing eastwards around Antarctica in a closed circulation with its flow unimpeded by continents.
Detailed explanation-2: -The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet.
Detailed explanation-3: -The Antarctic Circumpolar Current’s eastward flow is driven by strong westerly winds.
Detailed explanation-4: -Antarctic Circumpolar Current, also called ACC or West Wind Drift, wind-driven surface oceanic current encircling Antarctica and flowing from west to east. Affected by adjacent landmasses, submarine topography, and prevailing winds, the Antarctic Circumpolar Current is irregular in width and course.
