The objectives of the SeMPER O18 project are the reconstruction of changes in the origin of precipitation and the identification of isotopic signature of mesoscale phenomena affecting the polar region in Eastern Greenland. Those goals will be achieved by continuously measuring the isotopic composition (d18O and dD) of water vapor for a period of 4 years at Ittoqqortoormiit. Isotopic composition of precipitation will be also measured.
This project builds on the ongoing work of the transdisciplinary project SeMPER Arctic that aimed at understanding the sources of resilience in the Arctic by focusing on local narratives of changes in 3 Arctic communities, including Ittoqqortoormiit. The involvement of community actors in a co-production process will be a major asset of the project. The installation on site of a laser analyzer and its follow up will allow for the continuous measurement of isotopes of water vapor throughout the duration of the project.
