A view of the global ocean circulation shows currents swirling around the hills and valleys in the sea surface. Currents flow around hills in a clockwise direction in the Northern Hemisphere, and in an anticlockwise direction around valleys (the opposite occurs in the Southern Hemisphere). These currents form loops on either side of the Equator. Sea surface heights also vary across the oceans: the largest difference and height between the Pacific and the Atlantic is due to variations in salinity.
Use of altimetry measurements helped in proving that three "currents" identified in west and South of Australia (the Leeuwin Current, the South Australian Current and the Zeehan Current) were part of a unique current following the Australian coasts.
