What happens in the winter snowpack over the course of a winter?
Research leader: Kirsty Langley, Researcher, Asiaq – Greenland Survey
Other project participants: Alexandra Messerli, Researcher, Asiaq; Karoline Nordberg Nilsson, AC, Asiaq; Arno Hammann, Researcher, Asiaq; Ida Bomholt Dyrholm Jacobsen, Scientist, Greenland Institute of Natural Resources
Research area, purpose, and research question:
The purpose of this study is to understand the dynamics of the snowpack in the Kangerluarsunnguaq (Kobbefjord) area of Greenland and its implications for vegetation, wildlife, and human activities.
The snowpack plays a crucial role in insulating and protecting the underlying ground, affecting winter transport, recreation, and water resources upon melting. The research aims to model the evolution of the snowpack over recent and historic periods, with a focus on identifying the occurrence and thickness of ice layers.
The project combines local expertise from Asiaq and GINR and arctic snow modeling knowledge from the University of Uppsala.
The study will tailor a new snow model for Greenland conditions, using data-rich Kangerluarsunnguaq as a calibration site, and run it for the first time in Greenland. The research questions involve the changes in the snowpack, the formation of ice layers, and their correlation with vegetation cover and type. The project will run a high-resolution snow model, leveraging existing data and logistical platforms, and adhering to FAIR principles for data sharing. The chosen method involves utilizing a coupled energy balance – snow model, developed by the project partner Van Pelt, with a detailed dataset for forcing, calibrating, and validating the model. The study will contribute valuable insights into the temporal and spatial evolution of the snowpack in the study site as well as paving the way for wider use of the model in Greenland.
Methods for capacity building in Greenland:
This project is a collaboration between the only two natural science research institutions in Greenland, Asiaq and GINR, as well as the University of Uppsala. The project will utilize the facilities and ongoing research activities at all three institutions, while also combining the local competencies and knowledge. A Master student will join the snow survey in Kobbefjord.
Methods for dissemination:
The project aims to publish one peer-reviewed paper on ecosystem relevant snowpack characteristics and changes in these over the historic period. The project and results will be presented at national (Greenland Science Week) and international (e.g. EGU, ASSW, IASC/NAGS) conferences, workshops, and meetings. Facebook and X updates will be made throughout the project through the participating institutes.
