Tonya DelSontro

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.

• Greenhouse gas dynamics of inland waters

• Quantification of methane ebullition (bubbling)

• Upscaling aquatic greenhouse gas and carbon emissions

• Anthropogenic impacts on climatic feedback of inland waters

• Hydropower reservoirs in the global carbon cycle

• Lake sediment greenhouse gas dynamic

• Carbon Dioxide Capture and Storage

• Climate Change and Geosciences

• Increasingly Complex Water Challenges

• Protection of Drinking Water from the Ravages of Climate Change

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.
