Carbon stable isotopes of coral cores from the Tropical South Atlantic

The coral stable carbon isotope data (δ13Ccoral) presented here derived from corals of the western tropical South Atlantic. The data was obtained from subfossil and modern corals from Maracajaú, Açu and Rocas Atoll reefs, dated from 1647 to 1692, and from 1928 to 2018. The data was also utilized to generate a composite δ13Ccoral for the region, which is a significant addition to the existing body of knowledge. This data can be employed in future studies that seek to obtain isotopic records of coral from the South Atlantic.The isotopic data was derived from coral powder collected at a sampling resolution of 0.4 and 0.5 mm.

本文所提供的珊瑚稳定碳同位素比值（δ¹³Ccoral）数据，源自热带南大西洋西部海域的珊瑚样本。该数据采集自马拉卡雅乌（Maracajaú）、阿苏（Açu）以及罗卡斯环礁（Rocas Atoll）礁体的亚化石与现代珊瑚，其中亚化石样本的年代覆盖1647年至1692年，现代珊瑚样本的年代覆盖1928年至2018年。本数据集还被用于构建该区域的珊瑚稳定碳同位素比值复合序列，为现有相关学术研究成果提供了重要补充。该数据可应用于未来旨在获取南大西洋海域珊瑚同位素记录的相关研究。本次同位素数据的采集样品为珊瑚粉末，采样分辨率分别为0.4 mm与0.5 mm。
