Célia Julia Sapart was a PhD student at the Institute for Marine and Atmospheric Research Utrecht, Utrecht University, The Netherlands.The goal of her PhD project was to better understand the atmospheric budget of methane and nitrous oxide during the past two thousand years using stable isotope measurements on ice core air. In the summer 2012, she graduated with her PhD and went on with a Post Doc as a follow up of her PhD project. The EGU 2012 poster “Natural and Anthropogenic variations in methane sources over the last 2 millennia” presented high-resolution carbon isotope of methane data from Greenland ice cores over the last 2,000 years. Those data, together with atmospheric model results, allowed reconstructing how the different types of methane sources behaved in the past. It shows that both climate variability and anthropogenic activity played a role in the methane budget during this period.
