Constraints on the Antarctic Ice-Streaming Mechanism From Studies of Subglacial Sediment Cores

这一奖项是为了支持一项为期两年的研究，以继续对在西南极冰盖B冰流下获得的活塞芯进行系统的核心研究。这项研究的目的是验证这样一种理论，即通过润滑冰川床，冰犁负责快速的冰流运动。将对现有的核心材料以及作为这一项目和其他目前获得资金的项目的一部分将获得的新样品进行测量。还将检查样本中微化石的含量，这将提供有关南极洲西部冰川和气候历史的信息。

This award is for support of a two year study to continue systematic core studies of piston cores obtained beneath Ice Stream B on the West Antarctic Ice Sheet. The study aims to test the theory that by lubricating the glacier bed, the till is responsible for the rapid ice-streaming motion. Measurements will be conducted on both existing core materials as well as on new samples to be acquired as part of this and other currently funded projects. Samples will also be examined for their content of microfossils, which will provide information about the glacial and climatic history of West Antarctica.
