note = "Funding Information: Evidence for a multilayer sedimentary structure in USC exists through the differences in erosion thresholds associated with biofilm-sediment components consisting of chlorophyll, phaeopigment, and SPM variables (Sutherland, Amos, and Grant, 1998b). An increase in erosion thresholds ranging from chlorophyll, phaeopigment, and SPM (biofilm variables) at each flume deployment reflects the stratification of a surface {\textquoteleft}{\textquoteleft}fluff-aggregate{\textquoteright}{\textquoteright} layer and/or stabilized biofilm layer overlying a more consolidated sediment layer. A hydrodynamically active fluff layer located at the sediment–water interface was observed during SCUBA surveys in USC and was likely formed due to a headward residual motion of suspended sediment (Dowd, 1991), enhanced biodeposition by cultured bivalves (Kautsky and Evans, 1987), and biomediation of sediments by benthic diatoms (Sutherland, Amos, and Grant, 1998a). Thomsen and Gust (2000) also observed a two-layer system consisting of a surface aggregate layer overlying a sediment-dominant layer on the western European continental margin. The erosion thresholds of the thin surface layer (0.4–1.2 cm s–1) reported by Thomsen and Gust (2000) are comparable to surface erosion thresholds observed by Sutherland, Amos, and Grant (1998a) in USC (0.8–1.1 cm s–1). Further evidence for a multilayer sediment structure was supported by the nonlinear relationships between SPM and flume-derived U* profiles (Sutherland, Amos, and Grant, 1998b).
