s are seen during 195d. Fdvorite (1974) has shown that 

 mean sea level anomalies at Yakutat were well correlated 

 n annual wind stress transport anomalies in the Gulf of 

 uring the period 1950-59. 



Fairly persistent long-term sea level anomalies with short-term 

 fluctuations can be seen at Sitka/' Prince Ruperts Tofino/ Neah 

 Say/ and Crescent City. Sea level fluctuations are remarkably 

 coherent among these stations^ considering the 1800 km along the 

 coast between Sitka and Crescent City. Major periods of high sea 

 level are seen during 194C-41 and 1957-59. Low sea level periods 

 include 1955-36/ late IVdl-early 1962/ and 1964. A significant 

 period of anomalously low sea level is evident at Prince Rupert 

 between the years 1947 and 1951.

Sea level data from San Francisco/ Avila Beach^ Los Angeles^ and 

 La Jolla also exhibit similar fluctuations. Periods of high sea 

 level are noticeable during 1941/ 1951-52/ 1957-59/ and 1972-73 

 at all stations. Periods of high sea level during 1969 were 

 observed at San Francisco and Avila. Periods of low sea level 

 occurred at all stations during 1955 and early 1956 and during 

 1964- A strong trend of rising sea level in relation to Land 

 occurred at all stations in this group.

Mazatalan/ rtanzanillo/ Acapulco/^ Ealboar La Union/^ and 

 Buenaventura show similar patterns of sea level fluctuations. 

 Periods of high sea level correspond very well with El Nino 

 (Quinn 1976r 1978). All stations exhibit very high 

 during 1941-42/ 1937-59/ and/ to a lesser extent/ 

 high levels ijere noted during 1972-73.

Talara/ Callao/ Matarani/ Antofagasta/ and Caldera also show 

 remarkably coherent fluctuations in sea level. Like the group of 

 stations to the north/ p^^riods of high sea level correspond well 

 with El Nino conditions. The 1941-42 period of high sea levels 

 is evident at Matarani. The 1957-59 and 1965 periods of high sea 

 levels are seen at all stations, in this region. During 1972/ a 

 period of extremely high sea levels occurred at Talara peaking at 

 36.5 cm in December 1972. A maximum anomaly of 34.4 cm was 

 measured at Talara during November 1974. It is interesting to
