Individual shell sizes and shell weights of planktonic foraminifera from five samples from the Labrador Sea cores HU2008-029-004TWC, HU91-045-93BX and MD99-2227@en

Individual measurements of shell size and shell weight of distinct species of planktonic foraminifera from the sediment cores HU2008-029-004TWC, HU91-045-93BX and MD99-2227 from the Labrador Sea. Different shell size parameter (area, perimeter, minimum and maximum diameter, diagonal width and circle equivalent diameter) were measured using a KEYENCE VHX-6000 digital microscope. Individual shell weights were measured using a Sartorius Cubis®II ultra-micro lab balance (nominal resolution of 0.1 µg). Before weighing, the shells were left in the room for at least 24 hours to acclimate with the room, and for the water that was used to place them in the weighing boats to evaporate. The measurements were conducted to analyse the relationship of foraminifera shell size and weight, and to compare individual species-specific shell weight with bulk weighs conducted on samples from the same sediment core.本数据集收录了采自拉布拉多海HU2008-029-004TWC、HU91-045-93BX与MD99-2227沉积岩芯中不同物种浮游有孔虫的壳体尺寸与壳体重量的个体测量数据。研究人员使用基恩士（KEYENCE）VHX-6000型数码显微镜，测量了壳体的多项尺寸参数，涵盖面积、周长、最小与最大直径、斜向宽度及等效圆直径。个体壳体重量的测量则采用赛多利斯（Sartorius）Cubis®II超微量实验室天平，其标称分辨率为0.1 μg。称重前，需将壳体置于实验室环境中至少24小时以适配室温，并使用于将壳体放置于称量舟的残留水分完全蒸发。本次测量工作旨在分析有孔虫壳体尺寸与重量的关联关系，并将单一物种的壳体重量与同沉积岩芯样品的批量重量测量结果进行对比。
