Ocean trenches and ridges The motion of tectonic plates, and all of their associated volcanic and earthquake activity, are believed to be the surface manifestation of similar thermal convection occurring in Earth's mantle.
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.
