PART II: BACKGROUND OF THE EXPERIMENT 



Experiment Site 



12. Data collection activities were coordinated from a base camp estab- 

 lished on the beach near the north property line of the FRF. Figure 2 

 provides a plan-view sketch of the base camp, FRF coordinate system, and the 

 general physical arrangement of a typical data collection run (bathymetry 

 measured on 23 September 1986). The area near the north property line was 

 selected to avoid possible interference of waves, currents, and nearshore 

 topography in the vicinity of the experiments with the 600 -m- long FRF pier 

 located approximately 950 m to the south. An air-conditioned trailer located 

 behind the duneline provided a protected environment for data recorders and 

 other sensitive instruments.
