where 8 is the veering angle between the bottom velocity 

 and the bottom stress taken as 10°, consistent with the 

 theoretical results of Smith and Long (1976). 



The pycnocline depth was found from vertical density 

 profiles taken during MESA cruise XWCC-9 by averaging 

 the depths of the top and the bottom of the pycnocline. 

 The thickness of the lower layer (H - d) and the pyc- 

 nocline depth (d) during XWCC-9 are shown in figure 

 8-6. 



Each time period for averaged currents (fig. 8-5) was 

 diagnosed separately. An example of the solution for I, is 

 shown for the first interval (May 18-23) in figure 8-7. 

 From eq. (8), the velocity pattern at 8 m above the bottom 

 is displayed in figure 8-8, along with the superimposed 

 observed velocities. Transports in the lower layers were 

 calculated from eq. (9) and are shown in figure 8-9. The 

 transports are easier to interpret in schematic form, so the
