Bulk sediment inorganic and organic analyses of sediment cores from the Bay of Bengal

This dataset is a compilation of new and previously reported results from bulk sediment inorganic analyses (major/trace, carbonate, and Sr/Nd isotopic compositions), organic analyses (total and isotopic C and N), and compound-specific organic analyses (biomarker concentrations) of sediment cores from cruise SO93 on R/V Sonne in the Bay of Bengal. These data are used as records of post-glacial changes in precipitation and vegetation to investigate the role of these changes in controlling provenance and chemical weathering of sediments exported by the Ganges-Brahmaputra rivers, and the potential climate feedbacks through organic-carbon burial in the Bengal Fan.

本数据集汇编了孟加拉湾海域R/V桑尼号（R/V Sonne）科考船SO93航次所获沉积物岩芯的多项分析数据，收录新增与既往已发表的全岩沉积物无机组分分析（常量/微量元素、碳酸盐组分及锶（Sr）/钕（Nd）同位素组成）、有机组分分析（总碳、总氮及其同位素组成），以及单体有机化合物分析（生物标志物浓度）。该数据集可作为冰期后降水与植被变化的代用记录，用于探究此类变化对恒河-布拉马普特拉河（Ganges-Brahmaputra Rivers）输运沉积物的物源及化学风化过程的调控作用，同时可揭示孟加拉扇（Bengal Fan）有机碳埋藏所引发的潜在气候反馈效应。
