Abstract:

The main sources of nssSO42-  and NO3- were summarized in this paper. By analyzing the spatial distribution features of major ions in Antarctic ice sheet and studying on the different time of the same volcanic event recorded by different ice cores from different regions in Antarctica, this paper intends to study the transmission path of nssSO42- and NO3-. Results show thatnssSO42- and NO3- are transmitted to the ice sheet through long distance and high altitude. The procedure of the transmission is that nssSO42- and NO3- are transmitted to the level between the top of troposphere and the bottom of stratosphere, then subsided to the ice sheet surface and spread to other regions.

Key words: Antarctic ice sheet, nssSO42-, NO3-, transmission path
