The characteristics of chemical compositions and surface mass balancein the present-day snow, Antarctica

阐明化学物质向现今南极内陆区的迁移和沉积过程具有重要意义。在这项研究中，我们的目的是澄清从沿海地区的表面雪的化学特征，南极洲的圆顶富士。这些样本是由日本南极研究考察队收集的。我们分析了pH值，电导率，水的稳定同位素，和主要的阴离子和阳离子。结果表明，南极表层雪的化学特征因输送路线的不同而不同。

It is important to clarify the transportation and depositional processes of the chemical substance to the current Antarctica inland area. In this study, we aimed to clarify a chemical characteristic in the surface snow from the coastal area to the Dome Fuji, Antarctica. The samples were collected by Japanese Antarctic Research Expedition. We analyzed the pH, electric conductivity, stable isotope of water, and major anions and cations. As a result, the chemical characteristics in the surface snow of Antarctica were different according to the variation of the transportation routes.
