Cores U1523A, U1523B and U1523E were taken from the Iselin Bank, eastern Ross Sea, Antarctica (74°9.02′S, 176°47.70′W) in 828 m water depth during International Ocean Discovery Program Expedition 374. Grain size analysis of the 1 mm) was measured by dry sieving 1 cm³ subsamples using a nested stack at half-phi intervals (1.4 mm - 16 mm). Grain-size data is presented as the sand%, silt%, clay% and gravel%, sand%, mud% fractions according to the following grain-size intervals: very fine-coarse sand (1 mm - 62.5 μm), silt (62.5 - 4 μm) and clay (<4 μm). The volume mean grain-size diameter is also presented (D4,3).
