这项探索性研究的小额资助支持了对以前从舌提卡斯大陆边缘收集的沉积物岩心进行古地磁调查。许多这些核心最初解释的方法,虽然先进的时间,几乎是不够的。尽管如此,这些结果仍然被用来构建海洋沉积物和与南大洋,全球气候和tingticas冰川历史相关的重大事件的整体地层记录。随着几十年来古地磁技术的进步,以及ANDRILL和ShalDrill等重大项目对南极海洋沉积物的极大兴趣和目前的工作,需要对这些岩心进行重新评估。此外,这些新的研究将提供对地球切向圆柱体内地磁场行为的深入了解,由平行于地球自转轴并与内核边界的赤道相切的假想圆柱体划定的区域。这项工作的更广泛影响包括支持博士后研究,并通过增进对南极的了解来增进社会对全球气候变化的了解海洋沉积物记录
英文摘要
This Small Grant for Exploratory Research supports a paleomagnetic survey of previously collected sediment cores from Antarcticas continental margin. Many of these cores were originally interpreted with methods that, though advanced for their time, were barely adequate. Nonetheless, these results are still used to construct an overall stratigraphic record for marine sediments and major events related to the Southern Ocean, global climate, and Antarcticas glacial history. With the advances in paleomagnetic techniques over the intervening decades and the great interest and current work on Antarctic marine sediments by major projects such as ANDRILL and ShalDrill, a reassessment of these cores is needed. In addition, these new studies will offer insight into the behavior of the geomagnetic field within the Earths tangent cylinder, the region delineated by an imaginary cylinder parallel to the Earths rotation axis and tangent to the equator of the inner core boundary.The broader impacts of this work include support of postdoctoral student research and improving societys understanding of global climate change through an improved understanding of the Antarctic marine sediment record.
