Supporting data for Oceanographic and biogeochemical change in the high-latitude North Atlantic during marine isotope stage 11 and the common era

These files contain all of the new data presented in different chapters from my PhD. Datasets from each chapter with new data are separated into their own files. The Chapter 3 file contains isotopic ratio measurements of nitrogen, carbon and oxygen from foraminifer microfossils extracted from core MD99-2277 in the Nordic Seas. The Chapter 4 file contains isotopic ratio measurements of carbon and oxygen from foraminifer microfossils extracted from core IODP U1314 in the subpolar North Atlantic (Iceland Basin). The Chapter 5 file contains nitrogen isotope ratio measurements from a crustose coralline alga extracted from the Labrador Shelf. The Chapter 6 file contains carbon and nitrogen isotope ratio measurements from 2 crustose coralline alga replicate specimens extracted from western Greenland. The Chapter 6 file also contains percentages by mass of carbon and nitrogen in each of these specimens, and the corrected carbon isotope ratio values based on changes in the percentage of carbon content.

本数据集汇聚了作者在其博士论文不同章节中呈现的全新数据。各章节的新数据集均分别独立成文件。第3章文件记录了从北欧海域核心MD99-2277中提取的放射虫微化石的氮、碳和氧同位素比值测量结果。第4章文件包含了从北极北大西洋（冰岛盆地）核心IODP U1314中提取的放射虫微化石的碳和氧同位素比值测量数据。第5章文件记录了从拉布拉多架提取的皮壳珊瑚藻的氮同位素比值测量结果。第6章文件包含了从西格陵兰提取的2个皮壳珊瑚藻重复样品的碳和氮同位素比值测量数据，以及每个样品中碳和氮的质量百分比，并基于碳含量百分比的变化对碳同位素比值进行了校正。
