Radiocarbon data determined on sediments from coastal marine inlets and fjords in South Georgia and Rauer Group, East Antarctica@en

The data set comprises radiocarbon (14C) ages obtained on three sediment cores (Co1010, Co1305 and PS81/283) and additional information on the sample preparation of compound-specific 14C ages and carbonates. 14C ages were measured on different fractions of organic and inorganic carbon extracted from the sediments: bulk organic carbon (bulk OC), carbonates (foraminifers and mollusc shell debris) and fatty acids of different chain lengths (FA). The ages are presented and discussed in Berg et al. in review (Compound-specific radiocarbon analysis of (Sub-)Antarctic coastal marine sediments - potential and challenges for chronologies)本数据集包含取自3根沉积物岩芯（Co1010、Co1305及PS81/283）的放射性碳（14C）测年数据，以及化合物特异性14C测年与碳酸盐样品前处理的相关补充信息。本次测年针对从沉积物中提取的不同组分有机碳与无机碳开展，涵盖总有机碳（bulk OC，全称bulk organic carbon）、碳酸盐组分（有孔虫及软体动物贝壳碎屑）以及不同碳链长度的脂肪酸（FA）。相关测年数据的详细阐述与讨论见Berg等人的待审稿论文《（亚）南极沿岸海洋沉积物的化合物特异性放射性碳分析——年代学构建的潜力与挑战》。
