Specific projects include modeling the Earth's magnetic field; simulating ice age development and the accompanying variations in sea level; enhancing a coupled atmosphere-ocean-ice-land climate model; simulating the distribution of methane and carbon monoxide in the troposphere; and modeling the thermal convection process within the Earth's mantle, which causes plate tectonics. Similar to temperature gradients driving thermal convection, these concentration gradients also can drive fluid flow (solutal convection).
