14C Measurements in Large-Volume Ice Samples from Pakitsoq, West Greenland

This dataset contains measurements of 14CH4, 14CO and 14CO2 in large-volume ancient air samples extracted from glacial ice at the Pakitsoq site, West Greenland. The main objective of the project was to measure 14C in past atmospheric CH4 over the Younger Dryas - Preboreal climatic transition to constrain the source of the abrupt atmospheric methane increase at that time.

本数据集收录了从西格陵兰帕基特索克（Pakitsoq）点位冰川冰中提取的大体积古空气样本内的碳-14标记甲烷（14CH4）、碳-14标记一氧化碳（14CO）及碳-14标记二氧化碳（14CO2）的测量数据。本项目的核心研究目标为：在新仙女木期（Younger Dryas）-前北方期（Preboreal）气候转型时段内，测定地质历史时期大气甲烷中的碳-14含量，以此约束彼时大气甲烷浓度突增的来源。
