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.
