Organic matter dynamics in terrestrial and aquatic ecosystems

We investigate fundamental processes controlling carbon and nutrient stores in plants, soils and sediments within natural and managed ecosystems.

We also study how factors such as mineral surface adsorption, environmental conditions and disturbance by drought and fire, mediate fluxes of organic carbon and nutrients.

Our aim is to accurately assess the chemical nature and source of sequestered carbon in long-term residence pools and to properly assess the organic carbon storage or loss potential of specific land uses and climate change. Such approaches are integral to understanding the productivity of both terrestrial and aquatic systems.
