Joint Seismic and Geodynamic Inversion for Whole Mantle Structure

本项目的目标是（1）更好地约束 地幔通过节理的粘度和流动结构 大地水准面/地震数据拟合，（2）开展自洽反演 体波（S和P）、表面波和简正波的格式 在地震反演过程中包括由于 任何内部密度引起的边界变形 异常，（3）探索相变的影响， 内部横向（温度依赖性）粘度变化 地幔结构和大地水准面的二维和三维数值模拟 实验和地震数据集的相互比较。

The goals of this project are (1) To better constrain the viscosity and flow structure of the mantle through joint geoid/seismic data fitting, (2) develop a self-consistent inversion scheme for the body wave (S and P), surface wave, and normal mode data that includes in the seismic inversion process the effects due to the boundary deformations induced by any internal density anomalies, and (3) explore the effects of phase transitions and lateral (temperature-dependent) viscosity variations on internal mantle structure and the geoid through 2-D and 3-D numerical experiments and seismic dataset intercomparisons.
