Complex Principal Component Analysis is applied to bathymetric data from the SUPERDUCK experiment at Duck, NC. This approach is shown to describe more of the variation with fewer functions than conventional PCA. Further, it is shown to detect coherent wave-like sand motions through the data set, which can not be detected without complex analysis. These techniques are applied both to cross-shore and to alongshore profiles. Wave-like sand motions are detected in both directions in this data set.
