Fragment Size Variance: A New Proxy for Estimating Planktonic Foraminiferal Preservation in Deep-Sea Sediments

this dataset contains the dissolution and preservation proxy values calculated from analyzing whole and fragmented planktonic foraminifera test sizes in 62 core-top samples in the tropical indian ocean. these core-top samples were collected during expeditions on the rv marion dufresne and rv baruna jaya 1 and archived in the repositories at the centre européen de recherche et d'enseignement de géosciences de l'environnement (cerege, france) and laboratoires des sciences du climat et de l’environnement (lsce, france). the water depth of the core-top samples ranged between 364 m and 4425 m. the test size measurements were acquired using a state-of-the-art automated machine (miso). in addition, for each core-top sample, in addition, for each core top sample, foraminifera size and oceanographic metadata are also included in this dataset.

本数据集包含通过对热带印度洋62个岩心顶部样品中的完整及破碎浮游有孔虫壳体尺寸进行分析所计算出的溶解度和保存代理值。这些岩心顶部样品在RV Marion Dufresne和RV Baruna Jaya 1号考察期间采集，并存储于法国环境地球科学研究和教学中心（CEREGE）及气候与生态环境实验室（LSCE）的档案馆中。岩心顶部样品的水深介于364米至4425米之间。测试尺寸的测量采用最先进的自动化机器（MISO）完成。此外，对于每一个岩心顶部样品，本数据集还包括有孔虫尺寸和海洋学元数据。
