(250 m) widened in two areas, 375 m north and 400 m south of the pier. The 
trough under the pier intruded farther into the storm bar (300 m) having mi- 
grated 100 m farther south. 
126. The 14 July survey (Figure C5) shows continued shoaling of the 
trough under the pier. The scour hole at the end of the pier had again 
shifted and extended seaward of the pier end. The storm bar (300 m) remained 
unchanged; however, the nearshore bar and trough (175 m) were completely 
removed. 
127. Only minor changes were visible on the 24 August survey (Fig- 
ure C6). These included some erosion along the beach step (150 m) and an 
equal amount of deposition on the foreshore slope (100 m). 
128. Two poststorm bathymetric surveys were conducted during October. 
The first survey on 16 October (Figure 42) shows some notable aspects of the 
transition from summer to winter. First is the prominent nearshore bar and 
trough (100 to 150 m) created during this storm. This feature was built as a 
result of erosion (up to 1 m) at the base of the foreshore (120 m) creating 
the trough and a corresponding amount of deposition which built the bar 
(Figure 43). The trough under the pier deepened, and the scour hole at the 
end of the pier expanded shoreward; only slight changes were visible on the 
offshore bar and trough (200 to 400 m). Since the second survey on 27 October 
(Figure C7) followed a major storm (as compared to the 16 October survey which 
was also poststorm), many of the observable changes during the month are not 
as dramatic as they would have been had there been a prestorm survey. How- 
ever, the second survey of the month shows a dramatic further deepening of the 
pier trough (north of the pier) and of the scour hole. Both the nearshore 
(100 to 500 m) and the offshore (200 to 400 m) bar systems continued to 
develop as their troughs deepened and deposition occurred on the bar crests. 
Significant amounts of accretion were also visible on most of the foreshore 
(50 to 150 m) extending from the toe of the dune to MSL. 
129. The next survey on 6 December (Figure C8) shows a continuation of 
the prominent nearshore bar and trough with some deposition occurring in the 
trough under the pier and in the large scour hole at the end of the pier. 
South of the pier the storm trough (300 m) deepened significantly; however, 
the same did not occur north of the pier. 
130. In summary, fairly minor bathymetric changes occurred from January 
to September; however, following a storm in mid-October and a major storm late
