Earth Surface Processes

We reconstruct past environments across many different environments on Earth from the tropics to the poles, ranging in timeframes from large-scale, long-term climate changes (glacial-interglacial cycles) to abrupt climate changes.

In these environments, we work to understand the long-term natural baseline, environmental forcing, response and recovery, and human impacts, which in turn helps to inform effective decision making in the context of future environmental change. We have a wealth of expertise in palaeoecology (e.g. diatoms, pollen, dinoflagellate cysts), palaeolimnology, geomorphology, geochemistry and geochronology (luminescence dating) and physical and documentary archives.
