摘要
Abstract
During the Austral summer of 1996/1997, the First Chinese Antarctic Inland Expedition reached the inland area about 330 km along the direction around 76°E from Zhongshan Station, and collected 84 surface snow samples at an interval of 4 kin. Micro-particle analysis of the samples indicates that the micro-particle concentration apparently decreases with the increasing of altitude, and the amplitudes of micro-particle concentration is much larger in the lower altitude than in the higher altitude. Further analysis of grain-size distributions of micro-particle, percentage of micro-particles from different sources and variations with altitude suggest that microparticles in this area are from a considerably dominant source. Although this area is controlled by polar easterly wind and katabatic wind, transportation and deposition of the micro-particles are mainly influenced by marine transportation in coastal area.关键词
