Collection of the minigrid survey data under the changing DELILAH 
conditions was arduous. Some of the profile lines were perilously close to the 
instruments. Many individuals contributed to the survey data collection, most 
notably Messrs. Kimble Milliken, Doug Alden, and Brian Scarborough who 
-drove the CRAB and Mr. Steve Blanchard who processed all of the data and 
assisted in its collection. 
Table Al provides a summary, by profile and survey number, of the data 
collected. Numbers in the table are of computed cross-section volume changes 
(m?/m) between successive surveys. Surveys were conducted daily, but 
conditions limited the operation of the CRAB during 12-14 October 1990, 
when only the inshore portion of the lines could be surveyed and some of the 
lines had to be skipped completely. Following Table A1 are plots of the 
minigrid survey data, which are presented in two ways. First, the original 
cross-section data are displayed as comparison plots between successive 
surveys of all of the lines surveyed (Figures A8-A25). Then, contour and 
perspective plots are shown for each survey (Figures A26-A44).
