13. ABSTRACT (Maximum 200 words) 



Surface sediment grab samples were collected along one profile line at the 

 Field Research Facility (FRF) at Duck, NC, over a 17. 8 -month period from March 

 1984 to September 1985. Profile surveys were taken about every 2 weeks, with 

 sediment samples collected approximately once a month. Extra profile and 

 sediment samples were collected after storms. This comprehensive data set of 

 beach profiles, sediment, and wave and weather conditions provides a unique 

 opportunity to examine natural profile changes and resulting changes in sedi- 

 ment grain- size distribution along the entire length of an active profile and 

 to test and evaluate models of beach profile/sediment interactions to changing 

 coastal processes. Spatial changes indicate that the most active part of the 

 profile at the FRF is the bar/trough area that alternately moves seaward after 

 storms and migrates landward during fair weather wave conditions. The highest 

 variability in sediment grain-size distributions occurred on the subaerial 

 beach and foreshore area. The most stable sediment distributions occurred on
