Courant Circumpolaire Antarctique

L'Antarctique est l'un des endroits les plus inaccessibles de la Terre. Les vents et les vagues, qui atteignent souvent des ampleurs rarement égalées ailleurs, ainsi que les icebergs rendent la navigation particulièrement difficile (d'où l'appellation de " 40èmes rugissants " donnée à cette zone). De ce fait, le Courant Circumpolaire Antarctique est l'un des courants les moins étudiés de la planète. C'est aussi l'un des plus singuliers, car il est le seul à ne pas être arrêté par un continent et, ainsi, à relier tous les autres océans, permettant le passage d'eau de l'un à l'autre.
