Particle size distribution in the mixed top 10-cm sediment layer. Distributions are expressed as a percentage of the volume concentration obtained from the merged results of the LISST-100X and the floc camera (figure inspired by McCave et al., 1995); vertical dashed red lines indicate the median diameter of the sample distribution; the vertical green line indicates sample location by work area (WA1–4). “Finer fraction” refers to particles <63 μm, including clay (<2.5 μm) and silt (2.5 ≤ x < 63 μm); “coarser fraction” refers to particles ≥63 μm and was identified as a biogenic sediment. Black and gray are used only to aid visualization and do not represent grouping of the samples. DOI: https://doi.org/10.1525/elementa.343.f2
