The Breecker group studies biogeochemical processes occurring at or near the land surface. We study soils and paleosols, caves and stalagmites, and other materials, such as volcanic glass, that give us insight into Earth’s past. We study timescales ranging from seasonal cycles to hundreds of millions of years. We use observations, mathematical models and both laboratory and field-based experiments to address an evolving range of questions. Current questions of focus include:
Are the accumulation of organic and inorganic carbon in soils related?
How does carbon cycling in soils differ/compare with carbon cycling deeper in the critical zone?
How did the weathering of rocks change during warm climates of the past?
