摘要

Snow samples collected from a 50 m firn core and two snow pits along the rnroute of the 1996/1997 Chinese First Antarctic Inland Traverse Expedition in Princess rnElizabeth Land, East Antarctica, have been analyzed for chemical composition and rnoxygen isotope ratio. Analyzing the relationship between the concentration and flux of rnmajor ions and accumulation rate can draw the following conclusions. 1 ) The rnconcentrations of major ions in the atmosphere in the study region is big enough so that rnthe concentrations of the ions do not vary with snow accumulation rate, that is to say,rnthe concentrations of major chemical species are independent of snow accumulation rnrate. 2) The results of analyzing the depositional styles of major chemical species rnsuggest that wet deposition dominates the major ions flux. In addition, there is no rnapparent correlation between nssSO2-4 fluctuations and isotope profile. This would rnindicate the short-term climatic effect of volcanism is not evident in the region.
