An ocean circulation model shows the Antarctic Circumpolar Current swirling around Antarctica, with slow-moving water in blue and warmer colors indicating faster speeds (red represents speeds above 1 mile per hour). But how much water is really flowing through the current?
Recent fieldwork provides unexpected results.
