seaward about 650 nautical miles and for an 18-month time period 

 extending from 1 April 1949 to 1 October 1950. The total number 

 of observations in each area and their temporal and spatial dis- 

 tribution are also shown. In the shaded areas one to 20 observa- 

 tions were made and in the unshaded areas no observations were 

 made. Equation (4) was fitted to the data. The statistical results 

 were as follows: 



Number of observations: Area B 239 



Area C 190 



Area D 176 



Area E 203

Figure 8 shows the location in time and space of 971 temper- 

 ature observations made in this area during fiscal year 1950. The 

 observations were not used in obtaining the regression equation 

 but were used as a control to see how well the regression equation 

 could estimate independently observed sea-surface temperatures. 

 The difference between the observed temperature and that esti- 

 mated from regression was obtained. The i-esults are summarized 

 in figui-e 9. The standard deviation of the differences was 2. 3 F 

 compared to 1. 9 F for the regression equation.
