Supporting data for \"Changes in planktic foraminiferal distribution, productivity, and preservation in the Barents Sea during the last three millennia\"

Paleoproduction changes in the northern and southern Barents Sea based on changes of abundance (absolute and relative) of planktic foraminifers and stable isotopes. Data of total and organic carbon and calcium carbonate content in the sediment was measured. The age-depth model from sediment cores was built based on a combination of lead 210 and carbon 14. See \"Changes in planktic foraminiferal distribution, productivity, and preservation in the Barents Sea during the last three millennia\".

本数据集基于浮游有孔虫（planktic foraminifers）丰度（绝对丰度与相对丰度）及稳定同位素（stable isotopes）的变化，分析了巴伦支海（Barents Sea）南北海域的古生产力变化。本次研究测定了沉积物中总碳、有机碳及碳酸钙（calcium carbonate）的含量。沉积物岩芯（sediment cores）的年代-深度模型（age-depth model）通过铅-210（lead 210）与碳-14（carbon 14）的联合测年方法构建。详细信息参见《近三千年来巴伦支海浮游有孔虫分布、生产力与保存状况的变化》（Changes in planktic foraminiferal distribution, productivity, and preservation in the Barents Sea during the last three millennia）。
