ABSTRACTThis project is the second generation analysis and modeling of seismological data from the Mantle Electromagnetic and Tomography (MELT) experiment conducted on the East Pacific Rist at 17 degrees South. The goal of this analysis is to develop a comprehensivew model based on models of mantle flow and melt generation that satisfies all the different types of seismological data simultaneously. There wil be four phases of analysis; analyzing seismic data and waveform information that have not yet been exploited, inverting all the seismological constraints jointly to find a three-dimensional, self-consistent model, testing 3-D anisotropic forward models based on physical principles and guesses about the flow pattern, and incorporaing other constraints, including working toward a joint interpretation with the team of modelers of the electromagnetic data.

本项目是对南纬17度东太平洋洋脊上地幔电磁层析成像（MELT）实验的地震学数据进行的第二代分析和模拟。 该分析的目的是建立一个基于地幔流动和熔体生成模型的综合模型，该模型同时满足所有不同类型的地震学数据。 将有四个阶段的分析;分析尚未开发的地震数据和波形信息，联合反演所有地震学约束以找到三维自洽模型，测试基于物理原理和关于流型的猜测的三维各向异性正演模型，并考虑其他约束，包括与电磁数据的建模团队进行联合解释。
