Diatom Records from the McMurdo Dome Ice Core: A Missing Link between Hydrosphere, Biosphere, Atmosphere, and Cryosphere in the Reconstruction of Past High Latitude

9316306凯洛格商学院这个奖项是为了支持一项为期一年的对麦克默多穹顶冰芯中的硅藻和其他生物成因微藻的系统研究，该研究正在于1993年至1994年夏季进行。物种的特性和来源(海洋性与非海洋性和南极特有或世界性)应能为最近和最有可能的生物来源提供一些指示。硅藻数量和特性的向下波动可能记录了风力和/或风向的变化。硅藻记录预计将提供另一个工具，将罗斯海和维多利亚南部陆地无冰区的古气候历史与南极东部和西部冰盖的历史联系起来。***

9316306 Kellogg This award is for support of a one year systematic study of Diatoms and other biogenic micropraticles in the McMurdo Dome ice core, which is being drilled during the austral summer 1993/94. The identity and provenance of the species (marine vs. non-marine and Antarctic endemic or cosmopolitan) should give some indication of the closest and most likely sources for biogenic particles. Down- core fluctuations in numbers and identity of Diatoms may record changes in wind strength and/or direction. The Diatom record is expected to provide an additional tool for linking the paleo- climatic history of the Ross Sea and ice-free areas of Southern Victoria Land with that of the East and West Antarctic ice sheets. ***
