珊瑚碳同位素对大气CO2苏斯效应的响应数据集（1521-2015年）

稳定的珊瑚骨骼碳同位素组成（δ13C）可以用来重建溶解无机碳（DIC）表面海水，及其长期的下降趋势在过去的200年（~1800-2000）反映了人为Suess影响表面海洋碳酸盐化学的影响。自2000年以来，全球大气中二氧化碳的浓度仍在上升，苏斯效应也在增强。考虑到珊瑚对外部环境压力源的弹性和适应能力，珊瑚δ13C对Suess效应的反应可能会发生变化，需要重新评估。本研究利用不同海洋合成的10个长珊瑚δ13C时间序列，重新评价了在变化环境下珊瑚碳酸盐化学对Suess效应的响应。

Stable carbon isotope compositions (δ¹³C) of coral skeletons can be used to reconstruct dissolved inorganic carbon (DIC) in surface seawater. The long-term declining trend of this DIC over the past 200 years (~1800–2000) reflects the impact of anthropogenic Suess effect on surface marine carbonate chemistry. Since 2000, global atmospheric carbon dioxide concentrations have continued to rise, and the Suess effect has also intensified. Considering the resilience and adaptability of corals to external environmental stressors, the response of coral δ¹³C to the Suess effect may have changed, necessitating reassessment. This study employs ten long coral δ¹³C time series assembled from diverse oceanic regions to reassess the response of coral carbonate chemistry to the Suess effect in a changing environment.
