Ph.D. Thesis: “Reading the Rain in Rocks: A late deglacial speleothem record from Sumatra, Indonesia”
Advisor: Associate Professor Nerilie Abram
My PhD research uses cave samples (speleothems) from Sumatra to evaluate tropical climate variability in the Indo-Pacific region over the last 16,000 years. I have approached this work from three main angles. First, I have used the conventional stable oxygen isotope proxy in speleothem carbonate to reconstruct changes in precipitation changes on multidecadal to centennial timescales. Secondly, I have used phase changes in the mineralogy of the speleothem to make inferences on how rainfall variability interacts with the cave system, and ultimately, the growth of my speleothem. Lastly, I have used modern observational data and output from climate models to delve deeply into the regional climatology affecting my site.
