Ramón y Cajal Researcher
Ariane Arias-Ortiz is a Ramón y Cajal researcher in the Physics Department at Universitat Autònoma de Barcelona. She holds a PhD in Environmental Science and Technology (ICTA–UAB) and is a former NOAA Climate and Global Change Fellow, during which she worked as a postdoctoral researcher at the University of California, Berkeley (USA). Ariane 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 ecosystems to store carbon and their potential contributions to nature-based climate solutions. Ariane and her team combine micrometeorological measurements with analyses of stable and radioactive isotopes in soils and water to study carbon and energy flows across terrestrial and aquatic interfaces, providing insights into how these fluxes respond to disturbance, land management, and a changing climate. In this context, she leads a mesonetwork of eddy covariance towers in the Ebro Delta.
