DEFINITION

  • The oscillation of water around an ocean basin is called an amphidromic system and causes the high tide wave crests and low tide wave troughs to move around ocean basins in a clockwise (S. Hemisphere) or counterclockwise (N. Hemisphere) pattern. In the center of this rotating wave is a node where the tidal range is zero. These systems have been found to occur in all the ocean basins except the Southern Ocean, where tide crests and troughs simply move east to west. (en)
