fixes. The outstanding features of this velocity profile are the narrowness of 

 the current, the high velocities, and the countercurrent on the right of the 

 Stream. The streaky, banded nature of the Stream, as showTi by the curve 

 connecting black squares, is probably not real. Neither the results obtained 

 from the towed electrodes nor those from the Loran fixes show a similar 

 streakiness of velocity across the Stream. It seems likely that the streaki-

ness is a false effect arising from internal inertial gravity or tidal waves 

 acting upon the density field. 



Fig. 33 shows the thermal field across the same section of the Stream. 

 Only the upper half of the ocean is shown, the total depth in that area 

 being nearly 4000 m. The warm core is wider than the core of high velocity 

 and extends toward the right into a weak countercurrent. This is contrary 

 to the first natural conjecture that high downstream velocities and high
