Fig. 303. Topography of the physical sea surface and of the isobaric surfaces (relative to the 

 500-decibar surface) for the oceanographic surveys. I, 25-26 March 1937, and II, 5-6 May 

 1937, of the profiles through the Califomian region of upwelling water (according to 



Sverdrup).

Fig. 304. Computed mean vertical circulation for both profiles I and II in the cross-section 

 through the Califomian region of upwelling water (according to Sverdrup). The direction 

 of the motions is indicated by the thick lines with feathers; the horizontal velocities are given 

 by the thin lines. The region indicated by -f -f -f + + shows a zone with stronger flow 

 parallel to the coast and directed into the picture.
