Title

Microbiological studies in Greenland- bridging soils, sediments and the atmosphere

(Kai Finster, Tina Santl Temkiv, Ulrich Gosewinkel Karlson, Teresa G. Barcena and Jacob Yde)

Abstract

Due to its pristine character, Greenland is an excellent natural laboratory for studying microbial communities and their interactions with the environment in the absence of direct human interference. On the other hand, Greenland and the Arctic in general, have shown to be extremely sensitive indicators of remote human action when it comes to evaluating the effects of increasing greenhouse gas concentrations as well as pollutants on the environment in general and on its macroscopic inhabitants in particular, plants and animals including humans, on a global scale. The response of microbial communities has primarily been addressed in relation to thawing permafrost and its positive feedback on increasing methane emission.

I will present and discuss some of our studies that bridge topics as diverse as methane sources and sinks in glacial forelands, sedimentation ponds along glaciers as windows into subglacial life and microbial communities in the atmosphere and their physiological status. I hope that these small appetizers will initiate discussions and ignite interest that could lead to future collaborations within the ARC framework.
