to Wust, 1957). 



given in this Table show considerable scattering due to random errors and inaccuracies 

 in the basic data. Nevertheless, they give a rather good idea of the budget of the water 

 transports in the South Atlantic space which is valuable in many respects. The final 

 budget of the meridional transports (current amounts) is practically perfect with a 

 discrepancy of only O-I million m^ sec~^ A complete balance between northward and 

 southward transports in each of the two troughs cannot be expected. In the Western 

 Trough the North Atlantic Deep Current with 27-5 million m^' sec^ towards the 

 south is the main circulation component ; this is very largely confined to the narrow 

 strip along the South American coast. The transport in the uppermost part and with 

 the Bottom Current together is only 9-0 million m^ sec^ In the Eastern Trough the 

 transport towards the north in the bottom and deep currents is exceedingly small.
