9321478 Mosley-Thompson This award is for support for a study to conduct anion and cation analyses of samples from polar ice cores to establish an annually resolved 800-year volcanic history for Greenland and a 4000-year history from Antarctica. The proposed 800-year Greenland record will complement the existing 1000-year record from South Pole Station and make detailed interhemispheric comparisons possible. The proposed 4000-year Antarctic record will extend from the South Pole volcanic record and ultimately complement the longer histories expected from central Greenland cores. Interhemispheric comparison of these high resolution (annual to decadal) time series will allow identification of those near-tropical eruptions which perturb the sulfuric acid content of the global atmosphere. ***

9321478莫斯利-汤普森该奖项是为了支持一项研究，对极地冰芯样品进行阴离子和阳离子分析，以建立格陵兰岛每年800年的火山历史和南极洲4000年的历史。 提议的800年格陵兰记录将补充南极站现有的1000年记录，并使详细的半球间比较成为可能。 提议的4000年南极记录将从南极火山记录延伸，并最终补充格陵兰中部核心的更长历史。 对这些高分辨率（年度至十年期）时间序列进行半球间比较，将有助于确定那些扰乱全球大气硫酸含量的近热带火山爆发。 ***
