carbon storage and transport in the Avenelles basin

AXIS 1: Source, transfer, transmission and storage of carbon along the land-coastal zone-atmosphere continuum;

My work in France will focus on characterizing the storage and transport of carbon through the Avenelles watershed, an agricultural landscape roughly 70 km east of Paris. Field campaigns performed in the summer of 2025 will expand an existing dataset of solute chemistry at across the watershed. This will inform a model that will be used to infer CO2 degassing and lateral carbon transport throughout the landscape using a variety of parameters, such as flow, dissolved inorganic carbon, CO2 concentrations, groundwater inputs, chemical reactivity, and thermodynamic principles. Models like this are of vital importance in our effort to understand the processes that contribute to CO2 evasion from rivers and to predict how carbon transport may change under a changing climate.
