* Positive = shoreline moves seaward; negative = shoreline moves toward 

 mainland. 

 ** Number in parentheses is number of 1-minute reaches included in analysis; 

 number varies for different time periods because surveys are not continuous 

 for entire coast. 

 t Data coverage = approx. 60 percent of total shoreline. 

 tt Data coverage = approx. 90 percent of total shoreline. 

 t Data coverage (1852-1980) = approx. 80 percent of total shoreline.
