Abstract

This project intends to improve our understanding of interglacial processes. Interglacials, the relatively brief warm intervals of Quaternary ice-age cycles, have varied significantly over the last 800 000 years in terms of their duration, timing, intensity and complexity. The reason for such diversity has eluded palaeoclimatologists for decades. This is because of the difficulty of dating marine and ice records, which best preserve interglacial histories. The projects plans to compile precisely dated time series of past interglacials that can be linked directly to these records, allowing robust comparisons between interglacial properties and changes in Earth's astronomical parameters. This ..
