A Sulfate-based Volcanic Record from South Pole Ice Cores

该奖项支持一个为期两年的项目，该项目旨在分析南极的浅层(~150米)冰芯，以构建覆盖过去1400年的每年可分解的硫酸盐火山记录。在00/01年度实地考察期间，将在南极回收两个浅冰芯，并将用于这项工作。极地冰芯的火山记录为研究火山活动和气候之间的联系提供了宝贵的信息。新的记录预计将是连续的，至少覆盖过去1400年。来自这些记录的信息将核实在现有的少数南极记录中发现的火山事件，并解决根据这些早期记录确定的重大爆炸性喷发的时间和规模上的差异。为实现拟议研究的目标，提供资金协助建造冰芯和环境化学研究的分析实验室。

0087151Cole-DaiThis award supports a two year project to analyze shallow (~150 m) ice cores from South Pole in order to construct an annually resolved, sulfate-based volcanic record covering the last 1400 years. Two shallow ice cores will be recovered at the South Pole during the 00/01 field season and will be used for this work. Volcanic records from polar ice cores provide valuable information for studies of the connection between volcanism and climate. The new records are expected to be continuous and to cover at least the last 1400 years. The information from these records will verify the volcanic events found in the few existing Antarctic records and resolve discrepancies in the timing and magnitude of major explosive eruptions determined from those earlier records. In order to achieve the objectives of the proposed research, funds are provided to assist with the construction of an analytical laboratory for ice core and environmental chemistry research.
