part the gradient was quite gentle over the entire bay (Fig. 

 35). Closely packed isotherms near the Palos Verdes Hills 

 may have been associated with a current to the south, but 

 the irregularity of the water adjacent to the shore from 

 Redondo south perhaps is more indicative of no gradient 

 motion (Fig. 36). 



Different degrees and locations of upwelling in the 

 north, cold water in the south, and the magnitude of iso- 

 thermal slopes occured on January 18, 1956, and December 29, 

 1955 (Figs. 37 and 38). In January, the central and southern 

 pattern nearshore was similar to that in November. In the 

 northern part of the bay, closely packed isotherms indicated 

 a rather rapid flow to the south without the subsequent flow 

 to the east noted in November. The slight gradients in the 

 central part of the bay would result in slow or non-flow 

 conditions, with an increased southerly drift in the southern 

 part of the bay. Offshore, small gyrals indicative of minor 

 convergences and divergences occurred, but they were likely 

 too insignificant to be visually represented (Fig. 39). The 

 isothermal pattern in the north and south part of the bay in 

 December compared closely with that in November. However, the 

 isothermal slope nearshore in the center of the bay was 

 straight and constant for more than 10 miles, and must have 

 resulted in a dominant flow to the south (Fig. 40). 



The subsurface water in December and January showed 

 dissimilarities as did the surface layers, but not to the 

 same degree. Also, some of the temperature features were much 

 the same in the two months. For example, in both December
