Micropaleontological Record of the Ligurian Sea Over the Last 27.4 ka: Planktonic Foraminifera, Reworked Coccoliths, and Sandy Fraction from Core NDT_22_2016

This study aims to expand our understanding of the paleoceanographic changes in the western Mediterranean during the Late Quaternary by investigating the planktonic foraminifera and the reworked coccolith records of the NDT_22_2016 core (27.4 ka cal BP to present) in the Ligurian Sea. To achieve this a robust age model was developed using 17 radiocarbon dates, allowing sub-millennial resolution analyses.本研究旨在通过对利古里亚海（Ligurian Sea）NDT_22_2016岩芯（年代跨度为27.4 ka cal BP至今）中的浮游有孔虫（planktonic foraminifera）与再沉积颗石（reworked coccolith）记录展开分析，以深化对晚第四纪（Late Quaternary）西地中海区域古海洋学变化的认知。为达成该研究目标，研究团队基于17组放射性碳测年数据（radiocarbon dates）构建了稳健的年代模型（age model），据此可开展亚千年分辨率（sub-millennial resolution）的相关分析。
