Mixed Diatom Assemblages in Pliocene to Recent Diamictons of the Central Ross Sea and the Siple Coast, West Antarctica

西南极洲罗斯海中部和西普莱海岸上新世至近代硅藻的混合硅藻组合

基本信息

项目摘要

This award supports a study of mixed diatom assemblages from Pliocene to late Quaternary glacial sediments in the Ross Sea region of Antarctica that are referred to as the Ross Sea Diamicton. This layer of glacial sediment is the record of glacial activity during the last glacial maximum and holds information about the waxing and waning of the West Antarctic Ice Sheet. This study will utilize samples that have been recovered in piston and drill cores from the Ross Sea and from beneath the West Antarctic Ice Sheet and will use modern quantitative methods for identifying and interpreting diatom populations. The data developed in this study will be used to test stratigraphic models for the Ross Sea Embayment. These stratigraphic models will be used to assess the level of dynamic behavior of the West Antarctic Ice Sheet, specifically the question of whether, and how often, this ice sheet has collapsed in the geologically recent past.
该奖项支持对南极洲罗斯海地区从上新世到晚第四纪冰川沉积的混合硅藻组合的研究,这些沉积物被称为罗斯海直径。这一层冰川沉积物记录了最后一次冰盛期的冰川活动,并保存了有关西南极冰盖消长的信息。这项研究将利用从罗斯海和西南极冰盖下的活塞和钻芯中回收的样品,并将使用现代定量方法来识别和解释硅藻种群。这项研究中开发的数据将用于测试罗斯海海湾的地层模型。这些地层学模型将被用来评估西南极冰盖的动态行为水平,特别是这个冰盖在最近的地质历史中是否崩塌,以及崩塌的频率。
