Average chemical compositions of marine tephras including major elementsand trace elements of sediment cores during POSEIDON cruise POS513 (Table 3a)@en

Average chemical compositions of marine tephras including major elements (normalized to 100% and unnormalized) as well as trace element data and selected trace elment ratios; last column indicates # of measured shards per method. Colum 3 shows the correlations made to Aegean arc eruptions.本数据集收录海洋火山碎屑（marine tephras）的平均化学组成，包含主量元素（major elements，涵盖归一化至100%与未归一化两种形式）、微量元素数据及筛选后的微量元素比值；末列标注了各测试方法对应的实测碎屑颗粒数量，第3列则展示了与爱琴海弧火山喷发（Aegean arc eruptions）的相关关联结果。
