| Abstract: | The concentrations of chemical species increase with the increase of distance from the top (6 800 m) of the Guliya Ica Cap. This trend is more obvious in the drilled snow samples than the fresh surface snow samples. It suggests that the chemical species are mainly terrestrial-derived, while chloride, sulfate and nitrate have other sources besides terrestrial-derived dust. The chemical concentration and Oxygen isotope changes at 5 km are due to snow melting. The changes from 0 to 1 km are caused by wind blowing. |
