作为西南极冰盖(WAIS)计划的一部分,该奖项是对一项为期一年的项目的支持,该项目旨在研究B冰流下冰川下沉积物的微古生物学特征(硅藻、有孔虫和其他微化石)。将被研究的沉积物是巴克莱·坎布在1991/1992年南极野外季节期间在B冰流上进行钻探计划的一部分。这项研究的目的是:1)识别西南极冰盖冰川的更新世和上新世时期,2)评价西南极的去冰川和冰前环境,3)评价沉积物来源和冰川混合,4)快速冰流(亚冰直到变形或底部滑动)的测试模型,5)提供基线地质和年代地层数据,辅助地球物理解释。
英文摘要
This award is for support of a one year project to study the micropaleontologic character (diatoms, foraminifera, and other microfossils) of sub-glacial sediments from beneath ice stream B, as part of the West Antarctic Ice Sheet (WAIS) program. The sediments to be studied were obtained by Barclay Kamb as part of his drilling program on Ice Stream B during the 1991/1992 Antarctic field season. The objectives of this study are to: 1) identify Pleistocene and Pliocene episodes of West Antarctic ice sheet glaciation, 2) evaluate deglacial and preglacial environments in West Antarctica, 3) evaluate sediment provenance and glacial mixing, 4) test models of rapid ice stream flow (sub- ice till deformation or basal sliding), and 5) provide base-line geologic and chronostratigraphic data as an aid to geophysical interpretations.
