Figure 1-10: A four-layer version of the deep and abyssal global thermohaline circulation and its upper level compensation flows. Bottom water is shown by a blue line, deep water by a green line, a red line is used for intermediate depth flows, and purple denotes the uppermost layer. Volume transport estimates (in Sverdrups) are in circles associated with the key path segments, and color changes indicate water mass conversion.
