Professor Chamberlain uses stable and radiogenic isotopes to understand Earth system history. These studies examine the links among climate, tectonics, biological and surface processes. Projects include: 1) examining the terrestrial climate history of the Earth focusing on periods of time in the past that had carbon dioxide levels similar to the present and to future projections; and 2) addressing how the chemical weathering of the Earth’s crust affects both the long- and short-term carbon cycle. Field areas for these studies are in the Cascades, Rocky Mountains, Sierra Nevada, the European Alps, Tibet and the Himalaya and the Southern Alps of New Zealand. Professor Chamberlain teaches courses at the undergraduate and graduate level in isotope biogeochemistry, Earth system history, and the relationships among climate, surface processes and tectonics.
