- Quantifying Isotope fractionation during adsorption. Adsorption onto mineral surfaces is a process that controls a large part of the isotope signal during weathering. However, the amount of fractionation is poorly constrained. We are conducting laboratory experiments under different conditions to determine these effects.
- Changes in CO2 drawdown since the Last Glacial Maximum: the past 18,000 years have seen an overall warming trend, even before humans started influencing the climate. Atmospheric CO2 concentrations have risen. As yet, however, we do not understand how the climate system evolved under these changing conditions. The answer could be archived in cave carbonates (speleothems), which we are examining.
- Weathering through the PETM: the Palaeocene-Eocene Thermal Maximum was a period of rapid climate warming 56 million years ago. Accompanied by a CO2 rise and ocean acidification, as well as extinction, it is used as an analogy of current and future climate change. However as yet we do not understand the recovery from this period of warming, and this is what we are studying.
