Mechanisms of moisture isotopic fractionation and Asian monsoon dynamics since the last glacial maximum

Project Overview

For this project we propose a multi-proxy (trace elements, water inclusion and carbonate δ18O) study on speleothems collected from sites along a SW-NE transect in a region dominated by the Indian monsoon. We will determine the degree to which the change in water isotope fractionation between the last glacial maximum and present-day is due to water recycling and/or temperature gradient. We will additionally quantify the effect using an isotope-enabled earth system model. The study will shed light on Asian monsoon dynamics and global water cycle.
