Global Environmental Change
Key transitions in Earth history including modern global change. A wide range of proxies and finger-printing techniques are employed to focus on issues of global change such as methane as a greenhouse gas, coastal and estuarine dynamics, modern and ancient sedimentary processes, Phanerozoic environmental change and associated biotic responses, the biogeochemistry of Archaean ecosystems and evolution of life through geologic time. In addition, we pioneer new research on the impact of ice sheet contamination and associated chemistry on climate change.
