We may ask how wildfire and permafrost thaw influence carbon cycling and water quality in boreal lakes? How will the alpine tundra methane sink be altered by warming temperature and shifts in vegetation composition? What are the microbial processes that drive increasing methane emissions from lakes? Can we use data synthesis and statistical models to predict how greenhouse gas exchange from northern ecosystems will change in the future?
We use a variety of field and laboratory-based approaches, data synthesis, statistical model development, and remote sensing tools. Some of our field and laboratory approaches include soil and sediment sampling, vegetation surveys, stable isotope analysis, portable greenhouse gas analyzers, soil/sediment incubations, dissolved carbon and nutrient analysis, microbial DNA sequencing, soil organic carbon analysis, and GIS.
