The proposed continuation of studies of the three-dimensional structure of the mantle expoit the large data sets created under previous funding, and the inversion techniques which have been developed, to recover more complete information on mantle heterogeneity and to quantify the uncertainty of the resulting models. It is proposed to study the P-wave heterogeneity of the upper mantle, to assess the requirement for anisotropy and to implement a number of extensions and enhancements of present techniques aimed at increasing the information which can be extracted from the data.

提议继续进行的地幔三维结构研究利用了在以前的资助下建立的大型数据集和已经开发的反演技术，恢复更完整的地幔非均质性信息，并量化结果模型的不确定性。建议研究上地幔的纵波非均质性，评估对各向异性的要求，并对现有技术进行一些扩展和增强，以增加可以从数据中提取的信息。
