Tables (Main and Supplementary) for: Isotopic Signatures of Heliconoides inflatus and Globigerinoides ruber for tracing calcification depth and upper ocean conditions in the Bay of Bengal and Andaman Sea.

This dataset comprises all tables associated with the study, including main manuscript tables (Tables 1–3) and Supplementary Online Material (Tables S1–S3), focusing on hydrographic, geochemical, and micropaleontological data from the Bay of Bengal and Andaman Sea. The dataset includes sampling details from the RV Sindhu Sankalp (SSK-98) expedition (January 2017), age–depth models for sediment cores SPC09 and SPC13, and measured stable isotope compositions (δ¹⁸O and δ¹³C, reported relative to the Vienna Pee Dee Belemnite, VPDB). Derived parameters such as reconstructed paleowater column temperature, carbonate ion concentration (µmol kg⁻¹), and Limacina Dissolution Index (LDX) are also provided for Heliconoides inflatus and Globigerinoides ruber from sediment cores and core-top samples. Supplementary tables include scanning electron microscope (SEM) imagery references, environmental datasets (depth, in situ temperature, equilibrium δ¹⁸O, and chlorophyll-a concentrations derived from NEMO–PISCES biogeochemical reanalysis for January and July), and statistical correlations among geochemical parameters. These data are used to reconstruct upper ocean hydrography, calcification depth habitats, and carbonate system variability, contributing to paleoceanographic interpretations in a monsoon-influenced region.本数据集涵盖本研究关联的全部附表，包括主论文附表（表1~3）及在线补充材料附表（表S1~S3），聚焦孟加拉湾与安达曼海的海洋水文、地球化学及微古生物学数据。 数据集包含2017年1月执行的“Sindhu Sankalp”号科考航次（航次编号SSK-98）的采样详情、沉积物岩芯SPC09与SPC13的年龄-深度模型，以及实测稳定同位素组成（δ¹⁸O与δ¹³C，相对维也纳佩德贝莱姆尼特标准（VPDB）报告）。针对沉积物岩芯及表层岩芯样品中的*Heliconoides inflatus*与*Globigerinoides ruber*，本数据集还提供了重建古水柱温度、碳酸根离子浓度（μmol·kg⁻¹）及Limacina溶蚀指数（LDX）等衍生参数。 补充附表涵盖扫描电子显微镜（SEM）成像引用信息、环境数据集（包括水深、原位温度、平衡态δ¹⁸O，以及基于NEMO-PISCES生物地球化学再分析数据获取的1月与7月叶绿素a浓度），以及地球化学参数间的统计相关性。 上述数据可用于重建上层海洋水文环境、钙化深度生境及碳酸盐系统变化特征，为季风影响区域的古海洋学解释提供数据支撑。
