APPENDIX 



Tabulations and plots of coastal upwelling indices 



The following pages display the coastal upwell- 

 ing indices by month, quarter, and year for 15 

 near-coastal points over the period 1946-71. The 

 display for each location comprises six pages. 

 The first four contain monthly values. The fifth 

 contains quarterly values. The sixth contains the 

 completion of the table of quarterly values and 

 the table of yearly mean values. 



The first column of figures on each page indi- 

 cates the month, quarter, or year to which the 

 information appearing on the same line pertains. 

 In the tabulations by month, the first two digits 

 refer to the year and the last two to the month. 

 For example, 4601 refers to January 1946. In 

 the tabulations by quarter the first two digits 

 again refer to the year and the last two refer to 

 the quarter. For example, 4601 in this case refers 

 to first quarter (Jan., Feb., Mar.) 1946. In the 

 tabulations by year the year is printed in full. 



The second column contains the value of index 

 for each period. The units are metric tons per 

 second per 100 m of coastline. These units may 

 be thought of as indicative of the average amount 

 (metric tons or cubic meters) of water upwelled 

 through the bottom of the Ekman layer each sec- 

 ond along each 100 m of a straight line directed 



along the dominant trend of the coast on a scale 

 of about 200 miles. However, it must be remem- 

 bered that because of uncertainty in exact values 

 of some of the constants employed and for other 

 reasons outlined in the section on "Method," 

 these indices should be regarded more as indic- 

 ative of relative flucuations of upwelling intensity 

 at each point than as quantitative measures of 

 absolute magnitude. The quarterly and yearly 

 values are averages of the monthly values 

 weighted by the number of days in each month. 

 An exception to this rule is February which is 

 considered to always contain 28 days in order 

 to avoid a different set of long-term means for 

 leap years. Such refinement is well below the 

 level of sensitivity of these indices. 



The third column contains the anomalies or 

 deviations from the long-term mean value of the 

 index at the particular point for the particular 

 month, quarter, or year over the 20-yr period, 

 1948-67. 



The values and anomalies are plotted to the 

 right of each page. The heavy line indicates the 

 values of the upwelling index while the lighter 

 line indicates the anomalies. The deviations of 

 the anomaly line from the zero line are shaded.
