Characterizing Permafrost Microbes in a Changing Climate

In a paper published in Nature earlier in 2015, former ESD researchers Jenni Hultman and Janet Jansson, ESD affiliate Maude David, and others applied multiple molecular technologies (collectively referred to as “omics”) to characterize microbial activity in the Arctic permafrost. They sought to determine the composition of microbial communities within permafrost, specifically this community’s role in degrading permafrost organic carbon and the subsequent production of CO2 and methane.

This work was conducted for the Next Generation Ecosystem Experiment—Arctic project (Next-Generation Ecosystem Experiments (NGEE Arctic) project, to which many ESD scientists have made key contributions.
