Predicting Micro to Macro-scale Hot-spot and Hot-moment dynamics in Arctic Tundra Ecosystems 

The overarching objective of this project is to determine the micro-scale mechanisms driving hot-spot and hot-moment carbon dynamics, for improving predictions of macro-scale carbon balance. This multi-scale interdisciplinary project will transform our knowledge of fundamental plant-soil-microbial interactions that govern past and projected carbon cycle dynamics in permafrost ecosystems, while advancing knowledge of the key biogeochemical consequences of permafrost thaw over space (i.e., plot to landscape) and time (i.e., seasonal to decadal).

The Power of Collaboration
My journey starts at Toolik Field Station (TFS), a research station located 370 miles north of Fairbanks, Alaska at Toolik Lake with an interdisciplinary group of Co-Principle Investigators (Co-PIs) and graduate students from three different institutions. As Arctic permafrost thaws, carbon that has been sequestered, or frozen in the ground for thousands of years, can

I miss my new family. Don’t get me wrong—I love my family at home very much. This adventure would not have been possible without the support of my wife and daughter. But I also miss the new family I found in the Arctic. I traveled north to conduct field research, to participate in a science
