Sedimentology and organic data from Arez3, Sado estuary

Texture (coarse vs. fine fraction), magnetic susceptibility (MS), organic matter content and organic chemistry data (%Corg, %N, δ13C, δ15N) performed for Arez3, a 13.5 m-long sediment core collected in the Sado valley (Portugal).针对采自葡萄牙萨杜河谷（Sado valley）的13.5米长沉积物岩芯Arez3，本数据集包含其粒度（粗组分与细组分）、磁化率（MS）、有机质含量，以及有机地球化学数据（%Corg、%N、δ¹³C、δ¹⁵N）的测试分析结果。
