Global and Regional Carbon Cycle Modeling

These researchers have two main lines of research, one global and the other regional. In the global study, they use a numerical earth system model of intermediate complexity in order to quantify the global carbon cycle, including CO2 levels in the atmosphere. The model, developed at the University of Minnesota and called MESMO, has modules of the atmosphere, ocean, and land, which interact dynamically and biogeochemically. One of the goals of this line of research is to understand the partitioning of carbon among the main carbon reservoirs in present and future settings. The second goal is to understand how the global carbon cycle changed in response to abrupt paleoclimate change.

The second line of research has a regional focus on Lake Superior. The group has a numerical model of the lake based on state-of-the-art regional ocean modeling architecture called ROMS. Goals of this line of research include characterizing the distributions of carbon and ecosystem structure and understanding the fate of pollutants and other passive particles in Lake Superior.
