PhD: StableIsotope records of abrupt monsoon variability based on authigenic carbonates from tropical lakes.

The response of the global monsoon to projected climate change is poorly understood, with significant disagreement between climate models. The Asian monsoon, the largest and most energetic of the Earth's monsoon systems, influences more than half of the world’s population. Many of these people are directly reliant on the behaviour of the monsoon.

My research focuses on abrupt changes in the Asian monsoon over the Holocene period, using carbon, hydrogen and oxygen isotope analysis of lake sediments from five maar crater lakes in north-eastern Cambodia. The aim is to provide a high-resolution record of summer monsoon variability through the Holocene that will reveal how these climate systems operate during periods of climatic instability and change.
