Climate variability in the Indian Ocean affects a large portion of the global population. Recent research has shown that not only were year-to-year fluctuations in climate in the geologic past different than today, there was even an interannual mode similar to the Pacific’s El Niño. This work aims to reconstruct climate variability on seasonal to centennial timescales during the Last Glacial Maximum (20,000 years ago) and the Last Interglacial (125,000 years ago) and explore the underlying the climate dynamics through data-model comparison.
This project necessitates a multi-proxy approach including stable isotopes (d13C, d18O) and minor (Mg/Ca, temperature) elements and data-model comparison from modelling output included in the recent Intergovernmental Panel on Climate Change assessment. The project can be tailored to focus on a particular interval or climate process.
