1 3. ABSTRACT (Maximum 200 words) 



This report presents highly accurate, approximately biweekly surveys of four selected beach profiles collected over 

 a period of 7 years at the Field Research Facility (FRF) of the U.S. Army Engineer Waterways Experiment Station, 

 Coastal Engineering Research Center in Duck, NC. These data are unique in that they cover the most active region of 

 the nearshore, from the dune out to a depth where net bottom changes appear to be negligible, and because they were 

 collected coincident with detailed measurements of waves and water levels. 



The data were collected between 1985 and 1991 using the FRF's Coastal Research Amphibious Buggy, or CRAB, a 

 10-m-tall motorized tripod, which, combined with electronic surveying instruments, is capable of accuracies of a few 

 centimeters in both elevation and distance. 



The report discusses the data collection methods, the sources of errors and data editing procedures, and gives a brief 

 summary of the profile data itself. Appendices contain tables and plots of the survey data, along with tables and plots 

 of the wave and water level data.
