Data for: Radiocarbon Measurements of Foraminifera with the Mini Carbon Dating System (Micadas) at the Centro Nacional de Aceleradores

Contributors: Roberta Guerra, Francisco-Javier Santos Arévalo, Rafael García-Tenorio Date: 2019-03-22 Description: A Carbonate Handling System (CHS from Ionplus AG) coupled with an automated graphitization system (AGE from Ionplus AG) has been tested to investigate the potential for running samples of foraminiferal carbonate for AMS 14C dating at the Centro Nacional de Aceleradores (CNA) in Seville. The reproducibility of 14C ages for blanks and standard materials indicates that reliable 14C analyses are achievable for carbonate samples with a 14C age up to 50,000 yr BP. 14C and δ13C measurements of monospecific plankic foraminifera and bulk carbonate from sediment cores collected during the VECTOR oceanographic cruise (TRANSMED) in Western and Eastern Mediterranean Sea are presented. Monospecific planktonic foraminifera younger than 1000 yr BP from the deep Mediterranean Sea were dated with a MIni CArbon DAting System (MICADAS) at the CNA.

数据集描述：将Ionplus AG公司生产的碳酸盐处理系统（Carbonate Handling System，CHS）与自动化石墨化系统（automated graphitization system，AGE，均来自Ionplus AG公司）联用，在塞维利亚的国家加速器中心（Centro Nacional de Aceleradores，CNA）开展测试，以探究利用加速器质谱¹⁴C测年（AMS ¹⁴C dating）处理有孔虫碳酸盐样品的可行性。空白样品与标准物质的¹⁴C年龄重现性结果表明，对于¹⁴C年龄不超过50000年BP的碳酸盐样品，可获得可靠的¹⁴C分析结果。本数据集展示了地中海西部与东部海域VECTOR海洋科考航次（TRANSMED）采集的沉积物岩芯中单种浮游有孔虫以及块状碳酸盐的¹⁴C与δ¹³C测量数据。其中，地中海深海区域年龄小于1000年BP的单种浮游有孔虫样品，已在CNA通过微型碳测年系统（MIni CArbon DAting System，MICADAS）完成测年。
