If the 0200 GMT data were not available, other data for a given day were used. 

 The station ECHO data are also taken by bathythermograph. The temperature 

 measurements are probably not as accurate as the PAPA data. The Cape St. 

 James, Triple Island, and Langara Island data were taken by lighthouse keepers, 

 and were made within the hour prior to daytime high tide. The Scripps Pier data 

 were collected by the Scripps Institution of Oceanography. 



A subjective examination of the data shows, for the PAPA, ECHO, Cape 

 St. James, and Triple Island observations, maximums in August or September and 

 rather flat minimums in February to May. The Langara Island and Scripps Pier 

 data show a more regular sinusoidal seasonal variation. At all stations there 

 appear oscillations with a duration of a few days to a few weeks at irregular in- 

 tervals. At the open-ocean locations these shorter-period oscillations occur less 

 frequently and their magnitude is smaller than at coastal locations. It is recog- 

 nized that there exists in the data another oscillation - a diurnal variability. 

 The amplitude of this diurnal oscillation is much smaller than that of the season- 

 al oscillation and will not be examined in this study. However, it must be 

 recognized as a factor in the overall variability.
