A new map of the baroclinic volume transport to 3000 m has been produced for the Southern Ocean, making use of all available historic hydrographic data in the area. The map complements the geopotential height anomaly map of Gordon et al. (1978). The construction of the transport map was facilitated by the strong vertical coherence of the flow found for the whole ocean area.
