Time-series of sea-surface temperatures recorded in the North Pacific 

 and North Atlantic over periods up to 40 years were analyzed by autocorrelation 

 and regression techniques. It was found that record lengths of 8 to 10 years 

 are necessary to obtain reliable long-term estimates of sea-surface temperature. 

 The analysis also showed that year-to-year differences exist in annual average 

 temperature and that such variability is to be expected.
