Ariane Arias-Ortiz is a RyC researcher in the Physics Department at Universitat Autònoma de Barcelona. She is interested in carbon biogeochemical cycling, ecosystem-atmosphere interactions, and the use of radionuclides in environmental materials to study present, past, and future processes. Her work focuses on understanding the capacity of wetlands to store carbon and their potential contributions to nature-based climate solutions. Ariane and her team combine micrometeorological measurements with the analysis of stable and radioactive isotopes in soils and water to study carbon and energy flows between wetlands, the atmosphere, and adjacent water bodies, providing insights into how these fluxes respond to disturbance, land management, and a changing climate.
