Size fraction >150 µm determination of sediment core LV76-21

Sediment for IRD determination was sampled from 1 cm-thick slices with steps of 2–4 cm through the core. Samples with a dry weight of approximately 10 g were wet sieved using a...用于冰筏碎屑（Ice-Rafted Debris，IRD）测定的沉积物，沿岩心以2–4厘米的步长切取1厘米厚的切片进行采样。干重约10克的样品采用[...]进行湿法筛分。
