摘要: 冰芯中MSA含量具有季节性变化规律, 夏季出现峰值, 冬季为低值. 一定地区MSA高含量和海冰扩展存在相关关系, 有的地区MSA含量还与ENSO事件有一定相关性. MSA/ nssSO42-比值对温度和来源区域都有很好的指示意义. 在一定的条件下冰芯中的MSA可以发生迁移和再定位, 由此也对利用冰芯MSA含量反演当时大气气溶胶中成分含量的准确性提出了质疑. 总结了近几年来冰芯研究中的MSA和nssSO42-, 特别是极地冰芯MSA的研究进展, 并对利用MSA来研究全球变化的前景进行了预测和展望.

Abstract: The concentration of MSA in ice cores exhibits a consistent and strong seasonal cycle, with a maximum concentration in summer layer and a minimum in winter layer. The relationships between MSA and temperature, sea-ice and ENSO events are different from different areas. Because MSA in ice cores has the mechanism of migration and relocation in certain conditions, it is doubtable to determine the simultaneous aerosol concentration by using MSA detection of ice cores, which may bring about more uncertainty. This review summarized the researches of MSA in ice cores from Antarctic Peninsula, Arctic Greenland Ice Sheet and so on. The foreground by using MSA to study the global change is also discussed and prospected.

Key words: MSA, ice core, sea-ice, ENSO
