It is widely recognized that the earth's climate is dynamic and that significant changes have occurred in the past. Paleoenvironmental records from ice cores are an important tool for understanding the processes responsible for previous climate changes. This award supports the measurement of the electrical conductivity of an ice core that will be drilled at McMurdo Dome, Antarctica in 1992-1993. Specific objectives of this proposal are: (1) to assist in determining the age/depth relation for the McMurdo Dome core and to provide the location of stratigraphic marker horizons; (2) to identify segments of the core that have anomalous chemical characteristics so that other research groups can direct their efforts to significant, short duration features and; (3) provide a record of the volcanic activity that has affected the area.

人们普遍认为地球的气候是动态的，过去曾发生过重大变化。冰芯的古环境记录是了解以往气候变化过程的重要工具。该奖项支持将于1992-1993年在南极洲麦克默多巨蛋钻取的冰芯电导率的测量。该提案的具体目标是：(1)协助确定McMurdo Dome岩心的年龄/深度关系，并提供地层标志层位的位置；(2)识别具有异常化学特征的岩心片段，以便其他研究小组能够将他们的工作重点放在重要的、短期的特征上；(3)提供影响该地区的火山活动记录。
