Abstract

The objectives of this study were to (i) construct a pumping system, (ii) operate the system and collect samples of suspended sediment across the width of the surf zone during two major field experiments planned for the SIS in 1997, and (iii) analyze the resulting samples for sand concentration, sand size distribution, total percent sand, total percent mud, and organic content. The purpose was to provide a high quality data set of pump samples with which to later test the sensitivity of indirect measurements of suspended sand concentration to the presence of suspended mud. The response of OBSs is known to be particularly sensitive to the presence of suspended mud ("turbidity") due to the inverse response of OBS output to grain size. Without better constraints on the proper interpretation of OBS time series, the overall conclusions with regards to net along-shelf transport of sand during storms may be in doubt (see following section).
