Dr. Merritt Turetsky is an Associate Professor and Canada Research Chair at the University of Guelph. She is a global carbon cycle scientist and a northern ecologist. Dr. Turetsky's research contributes to theoretical predictions of ecosystem function but also applies to regulation of carbon in a global change world. She is motivated by fundamental research that addresses societal needs, often focusing on soils. The majority of her program addresses what rapid changes in climate mean for northern food and water security in northern Canada and Alaska. For example, permafrost thaw affects infrastructure, land stability, and water quality. Thaw-driven changes are interfering with the ability of subsistence harvesters to access traditional hunting and fishing areas, but at the same time is increasing the area of productive, arable soils for local food production. Dr. Turetsky serves as the Canadian university liaison to NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) and is a founding member of the Permafrost Carbon Network, which currently has more than 350 members representing 24 countries. From these experiences, it is clear that issues affecting northern climate and food security are not only of interest to arctic countries, but are gaining traction around the world.
