Abstract:

WT5BZ] In this paper we summarized the main sources of nssSO 4 2- and NO 3 -. By analyzing the spatial distribution features of major ions in Antarctic ice sheet and studying on the different times recording the volcanic eruptions in different regions, this paper intends to study the transmission path of nssSO 4 2- and NO 3 -. Results show that nssSO 4 2- and NO 3 - are transmitted to the ice sheet by long distance and high level transmission. The procedure of nssSO 4 2- and NO 3 - transmission is that nssSO 4 2- and NO 3 - are transmitted to the ice sheet at the level between the top of troposphere and the bottom of stratosphere, then nssSO 4 2- and NO 3 - transmitted to the ice sheet surface and spread to other regions.
