Settling velocity of deep-sea plume aggregates. (A) Boxplots of the settling velocities of aggregates produced under a shear rate of G = 0 s^–1 under four (color-coded) sediment plume concentrations. (B) Boxplots of the settling velocity against the shear rate, for concentrations of 105–500 mg L^–1. For a comparison with the treatments in A and B, the settling velocities were normalized to the median particle size. (C) Fitted model curves (non-linear logistic-sigmoidal) of the settling velocity against particle size for aggregates produced under a shear rate of G = 0 s^–1. (D) Fitted model curves (non-linear logistic-sigmoidal) of the settling velocity against particle size for aggregates produced under a shear rate of G = 2.4 s^–1. The 95% confidence intervals are depicted for every modeled curve. For visual purposes, size data grouped in the four (color-coded) classes were plotted on the curves. The raw data can be found in Table S6. DOI: https://doi.org/10.1525/elementa.343.f4
