Fig. 11.-- Smoothed profiles of isobaric surfaces relative to the 1, 000-decibar sur- 

 face along 158° W., July 28 - August 6, 1950. Points are the result of dynamic 

 computations. Hugh M. Smith cruise 5, stations 28-51. 



Fig. 12.-- Zonal components of the geostrophic currents across 158° W. , July 28 - 

 August 6, 1950. Computations based on smoothed profiles of isobaric surfaces 

 (fig. 1 1). Current magnitude in cm/sec. East currents hatched. Hugh M. Smith 

 cruise 5, stations 28-51.
