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.
