Numerical Model Simulations of Global Climate and Lake Superior

Global climate has changed in the geologic past and is undergoing change today as a result of human activities. Significant climate changes in the past are typically accompanied by significant changes in the carbon cycle (e.g., abundance of carbon dioxide in the atmosphere), indicating the important role that carbon plays in climate change. In one of the main activities of this research, the researchers use three-dimensional numerical models of the global ocean and atmosphere to investigate how changes in ocean biology will impact the global carbon cycle and thus global climate. One of the goals is to quantitatively describe the feedbacks between biology and climate. Another focus of this research is to simulate the physical and biogeochemical changes occurring today in Lake Superior, again using a three-dimensional numerical model. Lake Superior modeling will include simulations of ecosystem that includes different life stages of important fishes as well as nutrient dynamics.
