INTRODUCTION 



The time-series analysis of sea-surface temperatures 

 is of interest to oceanographers, meteorologists, and 

 biologists. This study discusses methods used in an anal- 

 ysis of daily sea-surface temperatures. It is the first in a 

 proposed series and is primarily concerned with the effect 

 of missing data in certain regression and autocorrelation 

 analyses. Only enough detail of these analyses will be in- 

 cluded to ensure a degree of completeness to the present 

 study. 



Many time -series measurements have been made at 

 various locations. In the eastern Pacific Ocean such 

 measurements have been made by Canadian and American 

 oceanographers at coastal, island, and ship locations for 

 time periods up to 45 years. These data have been the 

 subject of numerous papers including, among others, those 

 of Pickard and McLeod 1 and Roden. 2 ' 3 This study differs
