My research examines cycles of carbon, heat and water in high latitude aquatic and marine environments. The motivation is to better understand greenhouse gas emission budgets, and factors that moderate the gas budgets in these systems. The geographic focus of research extends from local inland waters, like Lake Winnipeg, to Arctic coastal seas, and consequently a major theme of my research examines how carbon is cycled within and between nodes that connect in-land waters to the coastal ocean, and effects of river water and associated delivery of carbon and nutrients on the carbon cycling within the downstream marine environment. The research is multidisciplinary, with a strong field component. I use micrometeorological techniques, like eddy covariance, to characterize the exchange of gases (e.g., CO2, CH4, H2O) and heat between the aquatic/marine ecosystem and overlying air, and I make use of shore-based stations, boats and ships for measurements and water sampling.
