Planktonic foraminifera shell counts, weights and sizes from the Labrador Sea cores HU2008-029-004TWC, HU91-045-93PC and MD99-2227@en

Planktonic foraminifera from top intervals spanning at maximum over the bast 4 ka BP of three sediment cores from the Labrador Sea: HU2008-029-004TWC, HU91-045-93BX and MD99-2227. In all samples, planktonic foraminifera were determined to the species level (based on Brummer and Kucera 2022, https://doi.org/10.5194/jm-41-29-2022). The size and weight of foraminifera shells were determined for bulk samples and some individual shells in order to assess the mass accumulation rate of planktonic foraminifera in the area of the Labrador Sea.本数据集涵盖采自拉布拉多海（Labrador Sea）3根沉积岩芯（HU2008-029-004TWC、HU91-045-93BX及MD99-2227）顶部层位的浮游有孔虫（planktonic foraminifera），采样层位的沉积时间跨度最大覆盖距今4000年（4 ka BP）以来的序列。所有样品中的浮游有孔虫均已鉴定至物种水平，鉴定依据参考Brummer与Kucera于2022年发表的研究（https://doi.org/10.5194/jm-41-29-2022）。为评估拉布拉多海区域浮游有孔虫的质量堆积速率，研究人员对混合样品及部分单个壳体分别测定了有孔虫壳体的尺寸与重量。
