Merrill 9909175 This is an accomplished based renewal award to continue research in paleogeomagnetism. The basic approach has been to use global databases to examine assumptions used in paleomagnetism and to determine what information can be obtained about the properties of, and processes acting in, Earth's deep interior through the analysis of paleomagnetic data. The investigators plan to combine directional and intensity data in such a way as to maximize the information they can extract about evolution of boundary conditions imposed upon Earth's core. In much the same way as they have developed and applied analysis methodology for the geomagnetic polarity time scale in order to learn about the deep Earth, they intend to develop and use new methodologies from modern information theory for the characterization and analysis of secular variation.

这是一个基于完成的更新奖，以继续研究古地磁。基本的方法是使用全球数据库来检查古地磁中使用的假设，并确定通过分析古地磁数据可以获得关于地球深层内部特性和作用过程的信息。研究人员计划将方向和强度数据结合起来，以便最大限度地提取有关地核边界条件演变的信息。就像他们开发和应用地磁极性时间尺度的分析方法以了解地球深处一样，他们打算开发和使用来自现代信息论的新方法来表征和分析长期变化。
