Biogeochemical Cycles

The utilization and ultimate fate of C, N, Si, P, S, Fe and other bio-important elements are studied at USC both from the perspective of the modern ocean, but also with respect to deep time. Our approach is to utilize mass balance models, isotope tracers and reasonable inferences from the modern to understand paleo environments and the rock record. Diagenesis is a very important process in the transformation of sediments to rocks and we study this process extensively in the modern, through deep sediments, and into the rock record.
