Will a wetter High Arctic be greener? 

In summer 2021, two motivated students will have the rare opportunity to conduct fieldwork for their MSc thesis about effects of 24 years of increased summer precipitation in a high Arctic polar desert. The cold and dry areas of the High Arctic cover vast areas and are subjected to the most extreme warming on the planet. Still, plants show little responses to higher temperatures because they lack moisture. As sea ice shrinks the northernmost climate will become wetter due to increased evaporation from the ocean. Since most research has focused on climate warming the effects of increased precipitation are very understudied.

The work is a part of a larger research project investigating the hypothesis that mosses play a crucial role for soil formation in polar deserts under climate change. One project will focus on plant, particularly moss, responses such as changes is species composition, growth and nutritional status. Another project will focus on the ecosystem C balance through measurements of C-fluxes and soil C pools. It will be possible to influence the exact questions of interest within the scope of the project. Read more about the project: https://signelett.weebly.com/greenarc.html 

Our funding covers travel and two weeks stay at the Zackenberg research station in NE Greenland with Signe Lett and Anders Michelsen. It will also be possible to apply for additional funding to extend the stay.
