New Paleomagnetic and Environmental Magnetic Studies of Old Cores from the Ross Sea Sector, Antarctica

本项目对南极洲海洋沉积物岩心进行古地磁调查。美国大陆边缘。这些岩心记录了南极洲的历史？它们是全球气候变化的重要记录。新的测量方法改进了定年和区域相关性，以确定古环境条件和冰盖行为。这些地核也记录了地球？这可以让我们深入了解地球发电机的工作原理。该项目更广泛的影响包括博士后和本科生参与研究。这对社会也有影响。因为这项工作提高了我们对冰盖行为及其与全球气候系统联系的理解。

This project performs a paleomagnetic survey of marine sediment cores from Antarctica?s continental margin. These cores record the history of Antarctica?s ice sheets and are important records of global climate change. The new measurements improve dating and regional correlations to ascertain paleoenvironmental conditions and ice sheet behavior. These cores also record the earth?s magnetic field near the pole, which offers insight into the workings of the geodynamo.The broader impacts of this project include postdoctoral and undergraduate participation in research. There are also implications for society?s understanding of global climate change, since this work improves our understanding of the behavior of ice sheets and their links to the global climate system.
