Flow maps suggested that the Gulf Stream circuit is about 15,000 km long, 



20 

 so that roughly 13x10 cc of water is involved in the flow. 



The area of water of the North Atlantic from the equator to 60°N, 



7 2 

 including the Mediterranean, is about 4x10 km , and the total volume 



23 3 

 is about 1.6x10 cm . Consequently, the Gulf Stream circuit involves 



about 1 per cent of the North Atlantic water and has an average kinetic 



3 

 energy of approximately 6.3x10 ergs, as deduced from the Montauk data. 



The velocity associated with this kinetic energy is 110 cm sec . Peak 

 velocities in the swiftest part of the current reach about 250 cm sec 

 (Worthington, 1953). 



Turbulent velocities are random and have statistical features 

 which are relatively stationary in time. The large streaming motions can 

 be considered to be a shear flow which generates turbulence. Meanderings 

 of this flow, however, may be difficult to separate from turbulent fluctu- 

 ations. If the results for usual jet flows are an indication, (Townsend 

 1956) the fluctuating turbulent velocities within the stream should not 

 exceed 5 per cent of the stream velocity and so are probably below 10cm sec
