meter depths (e.g., station A-intertidal , station A-3.7 meters, station 

 A-6. 1 meters) . 



Stations A and C (all depths) were surveyed four times while sta- 

 tion B (all depths) was surveyed five times over a 15-month span which 

 included the beach replenishment period (22 March to 20 June 1977). 

 Sampling dates are shown in Table 1. 



For each intertidal survey the beach width (BW) was defined as the 

 distance from the highest point of the previous high tide extending into 

 the water to 61 centimeters below MLLW. In accordance with Dahl (1953), 

 sampling strata were determined by dividing the beach width into thirds: 

 the upper stratum representing the highest tide level (upper one-third 

 of the beach) , the middle stratum representing the middle one-third of 

 the beach, etc. Three parallel transect lines 50 meters apart centered 

 on the station reference point were alined perpendicular to the shore- 

 line (Fig. 2). Infauna were sampled by taking 10 core samples (8 

 centimeters in diameter by 10 centimeters deep) per stratum along each 

 of the three transects for a total of 90 cores per intertidal station. 

 Cores were taken at regular intervals on the center transect (transect 

 line 2) at each intertidal station by a line-point method. Along the 

 upcoast and downcoast transect lines (transect line 1 and 3) infaunal 

 cores were taken within 5 meters either side of the transect line; i.e., 

 by a stratified random sampling method (Fig. 2). Within each stratum 

 of these two outer transects, sampling distances along the transect and 

 to sampling points on either side of the transect were determined from 

 a random numbers table. 



Directly offshore of station reference points at 3.7- and 6.1-meter 

 depths below MLLW, samples were taken by scuba divers (Fig. 2). Fifteen 

 cores were taken at each depth. Cores were randomly taken within a 15- 

 meter-diameter circle about the boat anchor. Surge conditions did not 

 permit application of a systematic spatial design for collection of 

 samples at these nearshore depths. 



Intertidal surveys were made during minus tides (27 to 58 

 centimeters MLLW) and the 3.7- and 6.1-meter depth stations were sampled 

 during high tide. 



Sediment samples were collected for grain-size analysis and organic 

 and inorganic carbon content in 100-millimeter length by 45-millimeter- 

 diameter jars. At each intertidal station, four sediment samples were 

 taken (three for grain-size analysis, one for carbon analysis); two 

 samples were taken at offshore sampling points (Fig. 3). Samples for 

 carbon analysis were frozen until analyzed. 



The total number of samples taken and processed is shown in Table 

 2. Biological cores were sieved through a 0.5-millimeter sieve, Tyler 

 32 mesh (U.S. Geological Series sieve equivalent No. 35). All organisms 

 were counted and identified to the lowest possible taxon. At some
