本文展示并讨论了南极Dronning Maud以东S16-Dome Fuji站沿线雪盖中Cl、Na、SO/、N03和Be浓度的区域分布。海岸线上的氯和钠离子浓度随距离海岸内侧200公里处的距离呈指数下降。在内陆200-1000公里范围内，NaI浓度几乎保持不变。另一方面，在750公里以外，氯的浓度随着距离的增加而增加。此外，在大陆内部，Cl和Na·之间的贡献因子减小，而Cl/Nai比值和nssCl/Cl比值增大。这些结果表明，海盐气溶胶是从沿海地区向南极大陆内陆地区输送的，南极内陆高原存在海盐以外的氯源。与降温风区相比，沿海地区和内陆高原地区雪中SO/、N03和Be浓度相对较高。
We show and discuss the regional distributions of Cl , Na , SO/ , N03 and Be concentrations in snow cover along the route from S16 to Dome Fuji Station in east Dronning Maud Land, Antarctica. The concentrations of Cl and Na I at the coast exponentially decreased with distance from the coast up to 200 km inland. Between 200-1000 km inland, the concentrations of Na I were nearly con stant. On the other hand, the concentrations of Cl increased with distance beyond 750 km inland. Furthermore, the contribution factors between Cl and Na· decreased and the Cl /Na I ratio and the nssCl /Cl ratio increased toward the interior of the continent. These results indicate that sea salt aerosols are transported from the coastal region toward the inland region of the Antarctic continent, and that a source of Cl other than sea salt exists in the inland plateau of Antarctica. The concentrations of SO/ , N03 and Be in snow were relatively high in the coastal region and the inland plateau region compared with those in the katabatic-wind region.
