changes, the authors made simple measurements of updrift and downdrift spit 

 lengths at each time interval on each map. It was assumed that littoral drift 

 along this coast is from north to south. Inlet throat width was also mea- 

 sured. This information is presented in summary form in Table 11. In some 

 instances, subaerial area measurements were made to observe changes in island 

 or spit growth/erosion through time. Aerial change data are presented along 

 with a brief descriptive narrative of each inlet. No attempt was made to 

 estimate volume changes. Inlets that showed little alongshore change have 

 been omitted, their across -shore changes having been reported in the previous 

 discussion. The reader is reminded that the following discussion is based on 

 inlet position as mapped at distinct points in time and should not be used to 

 assume other than equally distributed changes during intervening periods. 

 Examination of shoreline changes around inlets on the accompanying shoreline 

 change maps is essential to understanding the descriptive narratives. Discus- 

 sion proceeds from south (Map 1) to north (Map 32) .

 are inlets located on maps 1 through 4 that have primarily onshore/offshore 

 changes and are adequately characterized by the shoreline change technique.
