order velocities v/ould also be altered when is changed. V/e 

 shall consider several values of © when we discuss the deflection 

 of the thermocline in the steady two-layer ocean. 



The mean mass transport of the Gulf Stream (corresponding to 

 the steady problem) is 26,6 x 10° metric tons per second as com- 

 pared to Mimk's value [51 of 36 z 10 and the observed value of 



6 

 72-80 X 10 metric tons per second. Munk [51 used the east-west 



component of an empirical v/ind system and the discrepancy is 

 therefore due to the difference between the tv/o wind systems, 

 At the time of maximum (minimum) wind the transport is 20^o higher 

 (lower) in accord with the remarks made previously in this sec- 

 tion. In the counter-current the steady mass tranport is ^-,61 x 

 10 metric tons per second. 



The difference betv/een the computed and the observed 

 values is not surprising when one considers the many idealizing 

 assumptions made. Such features as the straight coast lines, 

 the simplified theory of turbulence used, the neglect of the non- 

 linear terms, and a more realistic stress-effect of the wind on 

 the water could well change the quantitative results by a factor 

 of two or three. 



The problem as stated and solved by the above method 

 gives no sensible east-v;est variation in the position of the 

 Gulf Stream, but a careful investigation of the eastern boundary 

 of the Gulf Stream shows a very small narrowing of the stream. 

 How well such a result agrees v/ith field evidence is uncertain 

 since our solution yields no inshore counter-current.
