The Structure and Dynamical Properties of the Earth's Core

该项目将继续进行有关地核/地幔边界形状以及地核内部结构和物质性质的工作。继续对岩心结构等参数进行相走时数据反演。这种反演包括由边界地形和重力引起的外核内部结构的影响。它还将模拟：(a)内核（包括可能的内核结构）和(b)在非流体静力核/地幔地形存在下的外核粘度对地球强迫章动的影响。第(a)部分将包括尝试建立模型和预期的内核国家正常模式。

This project will continue ongoing work related to the shape of the core/mantle boundary and to structure and material properties inside the core. It will continue inversion of core phase travel time data for core structure and other parameters. This inversion includes the effects of structure inside the outer core induced by boundary topography and by gravitational forces. It will also model the effects on the earth's forced nutations of: (a) the inner core (including possible inner core structure), and (b) outer core viscosity in the presence of non-hydrostatic core/mantle topography. Part (a) will include an attempt to model and expected inner core nutational normal mode.
