Overview of Our Research

Our research aims to understand past changes in climate and ocean using fossilized lipids and calcite microfossils found in marine sediments which cover the seafloor. These fossils serve as a proxy for climate beyond the instrumental era. We focus on proxies used to derive seawater temperature, the so-called paleo-thermometer. As the proxy recording of climate signal are indirect, we strive to improve the interpretation of proxy data, including their reproducibility and inter-comparison between proxies. We aim to provide a better constraint for proxy-derived climate reconstruction, which in turn helps constrain the numerical models used to project future climate change.
