Current Project (2019-2021)

Interannual variability of the Indian Monsoon during the Late Holocene

Sub-decadal ocean-atmosphere oscillations impact climate around the globe. Indian monsoon system intensities are linked to the interannual El Niño-Southern Oscillation and the latitudinal position of the intertropical convergence zone. Understanding the Indian monsoon's interannual behavior under warm climates is critical--over 1.5 billion people are impacted by this system.

The monsoon system's interannual response to warming climate is poorly resolved, as instrumental records are limited (<150 years) and conventional paleoclimate proxies (e.g., lipid-based sea surface temperature [SST]) require sample sizes that integrate years. At the University of Bremen, we have the ability to congruently measure and map climate-relevant lipid biomarkers and elements from intact sediment core surfaces, unlocking the ability to reconstruct ultra-high resolution paleoclimate.

This project employs a revolutionary method to investigate the intensity and variability of the Indian monsoon for the past ~ 2000 years, using ultra-high resolution SST and precipitation proxies from northeast Arabian Sea sediments. I combine mass spectrometry imaging, micro-X-ray fluorescence, and time series analysis techniques to examine cyclicity in reconstructed SST and precipitation, which are both influenced by the Indian monsoon system.

This project is funded by the University of Bremen's Central Research Development Fund Call 04: Independent Projects for Postdocs.
