Refining the isotopic (Sr-Nd) signature of potential source areas for glacial dust in East Antarctica
The geographical origin of the mineral dust transported to the East Antarctic Plateau from the Southern Hemisphere (SH) continents has been investigated by means of the isotopic (Sr-Nd) signature of samples from Potential Source Areas (PSAs). Dust reaching Antarctica is fine-grained (<5 um), and...
