Mineral dust– climate » relationships in areas under the influence of 
the monsoon from present to the last million years
Charlotte Skonieczny (Université Paris-Saclay, CNRS, GEOPS, France)

This seminar explores “mineral dust–climate” relationships in 
monsoon-influenced regions from the present back to the last million 
years. It investigates how changes in atmospheric circulation and the 
hydrological cycle have influenced dust production, transport, and 
deposition under different climatic conditions, and how variations in 
the dust record can, in turn, be used to reconstruct past dynamics of 
atmospheric circulation and the hydrological cycle. The approach relies 
on multi-proxy characterization of the mineral dust deposits preserved 
in marine and lacustrine sedimentary archives. Sedimentological, 
mineralogical and geochemical tracers are used to identify dust 
provenance, reconstruct transport pathways, and track shifts in monsoon 
intensity and regional aridity. Particular attention is given to the 
link between dust supplies and primary productivity, including the role 
of dust as a supplier of micronutrients to marine and continental 
ecosystems. These reconstructions provide new insights into feedbacks 
between dust, climate dynamics, and ecosystem productivity across 
Quaternary timescales.

Charlotte Skonieczny, Associate Professor at Université Paris-Saclay, 
France, is a paleoclimatologist whose research focuses on reconstructing 
past changes in atmospheric circulation and the hydrological cycle in 
monsoon-influenced regions. Her research is based on a multi-proxy 
characterization of the inorganic fraction of sediments deposited by 
atmospheric or fluvial routes in marine and lacustrine sedimentary 
archives of these regions.
