1. Select the salinity interval of 30.00 to 39.99%o, pages 13 to 18. 



2. In column one, find the temperature interval in which 15.70 

 falls (always use the lower limit of the interval). The lower limit 



is is.bg-c. 



3. Entering column one at 15.69''C read the corresponding value 

 of 22.00 in column two. This is the correct a- value for the base 

 of the salinity interval, that is, for a salinity of 30.00%v, and temperature 



of is.eg^c. 



4. To find the correct o- value for the given salinity of 36,47%o, 

 multiply the designated f-factor in column three (.7680) by the last 

 three digits of the given salinity (6.47), observing decimal places, 

 and add the value obtained to the base value 22.00. 



5. Round the value obtained (26.96896) to two decimal places. 

 ANSWER 26.97 . 



Thus: Given 15.70°C and 36.47%o S. 



From table for Salinity 30.00 to 39.99%o, enter column one 

 at lower limit of temperature interval (15.69) 



obtain base / f-factor last three 



value in / of column digits of 



column two + I three x given S. 



22.00 \ .7680 6.47 



26.968960 (round to two decimal places) ANSWER 26.97
