Tonya DelSontro’s research focus is to advance our understanding of how human activities and climate change alter aquatic carbon cycles and greenhouse gas budgets. She integrates field-based system analyses and experimental laboratory work to define and predict anthropogenic impacts on aquatic greenhouse dynamics from local and regional to global scales.

Scholarly Research

Professor DelSontro’s research interests lie in understanding how anthropogenic impacts, such as eutrophication, influence carbon cycles and integrated greenhouse gas (CO2+CH4+N2O) budgets in lakes, rivers, reservoirs and wetlands/ponds. She aims to define the drivers of budget shifts and use them to better asses the vulnerability of other regions to human-induced changes in aquatic carbon dynamics. As the global warming potential of greenhouse gases vary, shifts in their emissions could lead to an exacerbation or an easing of climate change. Understanding our role in the climatic impact of inland waters will guide us in creating climate-friendly policies when managing our waterways.
