Saharan Dust Proxy Record from a Colle Gnifetti Ice Core (KCC)
Dust events originating from the Saharan desert have far reaching environmental impacts but the causal mechanism of magnitude and occurrence of Saharan dust events (SDEs) during the pre-instrumental era requires further research, particularly as a potential analog for future climate. Using an ultra-...

Dust events originating from the Saharan desert have far reaching environmental impacts but the causal mechanism of magnitude and occurrence of Saharan dust events (SDEs) during the pre-instrumental era requires further research, particularly as a potential analog for future climate. Using an ultra-high resolution glacio-chemical record from the 2013 Colle Gnifetti (CG) ice core drilled in the Swiss-Italian Alps we reconstructed a 2000 year-long summer Saharan dust record. We analyzed both modern (1780-2006) and pre-modern Common Era (C.E.) major and trace element records to determine air mass source regions to the Colle Gnifetti glacier and assess similarities to modern and reconstructed climate trends in the Northern Hemisphere. This new pSDE (proxy SDE) reconstruction, produced using measurements from a novel, continuous ultra-high-resolution (120-µm) ice core analysis method (laser ablation-inductively coupled plasma-mass spectrometer or LA-ICP-MS) is comprised of 316,000 data points per element covering the period 1 to 1820 C.E.
