ANOMALIES DURING 1976 



The time series since 1972 of anomalies of salinityr temperature^ 

 and heat storage given by Saur (1978) are extended to include 

 1976 anomalies (Fig. 7.5). The mean data from which the 

 anomalies were computed did not include the 1976 data^ but were 

 for the same 8-yr period (June 1 966-De cember 1970/^ January 

 1972-June 1975) used previously. The grid fields for the 

 anomalies were numerically smoothed by a 5 x 3 point (60 days by 

 100 n mi) before being contoured.

The outstandiog feature of surface salinity anomalies in 1976 was 

 the appearance of significant negative anomalies (below 

 -0.2 o/oo) at the California coast and also near the outer edge 

 of the California Current (near 2/800 km) in October. In mid- 

 November there was a band of negative anomalies (below -0.3 o/oo) 

 from near the California coast to midsection. Further^ anomalies 

 below -0.4 o/oo occurred in the Transition Zone and extended 

 toward Hawaii somewhat into the ENP region. These strong 

 negative anomalies appeared to be returning to near normal at the 

 end of the year.
