Using Q-mode factor analysis, 87 surficial sediment samples collected from Duck and Whalehead beach, North Carolina, were analyzed using the weight percent of the gravel and sand fraction subdivided at 0.5 phi class interval as variables. An additional data set composed of 178 surficial sediment samples from Duck beach (bimodal) and Coquina beach (unimodal fine) representing three years of sampling at monthly intervals were analyzed by the same technique using only the sand fraction. The spatial and temporal patterns of sediment factor groups support three main inferences. (1) Bimodal beaches display a more distinct sediment zonation than unimodal beaches. (2) …
