The ordinates of figures 5 through 9 are scaled to accommodate the numerical 

 means of the stations in each area. Since heights at each station are referenced, 

 independently, to the primary tidal bench mark at that station, the numerical 

 values, per se, on the ordinate are not comparable between figures. The numerical 

 values on the ordinate of the U.S. mean (figure 10) are, therefore, also arbitrary. 



VI. STATION GRAPHS AND DATA VALUES 



Two graphs for each of the 67 tide stations are given in appendix A. The first 

 graph shows the series average of monthly mean sea level (dotted) and a superimposed 

 curve (solid) of the most recent year of monthly mean sea levels. The second graph 

 is yearly mean sea level against time. The values are connected by straight lines. 



All monthly and yearly mean sea-level data from the 67 stations are listed in 

 appendix B. The numerical values in both appendices are referenced to the primary 

 tidal bench mark at each station location. Therefore, the numbers are not 

 comparable between stations without normalization. The year-to-year differences at 

 one station can be compared with the year-to-year differences at another, however 

 (neglecting geopotential differences).
