This is the lab website of Carolina Olid, Lecturer at University of Barcelona. We work at the intersection of environmental geochemistry and ecology, using radioactive isotopes and tracers to follow the movement of elements through landscapes, from soils and peatlands to rivers and lakes.

Our research focuses on how climate change and human activities modify the natural cycling of carbon, nutrients, and metals across terrestrial and freshwater systems. We are particularly interested in high-latitude and permafrost regions, where warming and environmental disturbance are rapidly transforming how elements are stored and released.

In our group, we combine fieldwork, lab analyses, and isotope tracing techniques to understand how environmental processes connect the land and water, and how these connections shape ecosystem function in a changing world.

We are based at the Faculty of Earth Sciences, where we collaborate with scientists from diverse disciplines to tackle environmental questions from multiple angles.
