Aerosol concentrations over the last climatic cycle (160 kyr) from an Antarctic ice core

Time series, covering more than 150,000 years for dust and marine salt loadings in the Antarctic atmosphere have been constructed from measurements of concentrations of aluminium and sodium in an ice core taken from East Antarctica. They exhibit an inverse correlation with δ 18 O measurements. These...

Description
Summary:Time series, covering more than 150,000 years for dust and marine salt loadings in the Antarctic atmosphere have been constructed from measurements of concentrations of aluminium and sodium in an ice core taken from East Antarctica. They exhibit an inverse correlation with δ 18 O measurements. These results extend our understanding of aerial transport processes during the last glacial cycle.
