Decreased terrestrial organic burial in subaqueous Changjiang Delta: Perspective from altered riverine POC sources

This dataset compiles observational and analytical data related to particulate organic carbon (POC) transport by the Changjiang River and organic carbon characteristics in the subaqueous Changjiang Delta. The dataset primarily includes the following three aspects:Dataset of 40-year POC characteristics (N/C, δ13C) in suspended sediment delivered by the Changjiang RiverOrganic carbon characteristics (N/C, δ13C and Δ14C) in subaqueous Changjiang DeltaTemporal changes in riverine organic carbon flux and net organic carbon preservation in deltaic regions

本数据集汇集了与长江输运颗粒有机碳（POC, particulate organic carbon）以及长江水下三角洲有机碳特征相关的观测与分析数据。本数据集主要涵盖以下三个方面：1. 长江输送悬浮泥沙中40年颗粒有机碳特征数据集（氮碳比、δ13C）；2. 长江水下三角洲有机碳特征数据集（氮碳比、δ13C与Δ14C）；3. 河流有机碳通量时间变化与三角洲区域有机碳净保存量数据集。
