CSEDI Collaborative Research: 3D Variations in Temperature and Water Content from Seismic and Mineral Physics Data

EAR-0001965 Romanowicz在这个合作项目中，研究人员的目标是在如何解决上地幔海洋和大陆之间含水量的横向变化方面取得进展，这对于我们了解大陆岩石圈的演化和动力学非常重要。为此，他们将把地震学和矿物物理学工具联合收割机结合起来。在矿物物理学方面，他们将致力于找到一种合适的参数化方法，通过这种方法可以适当地解释水对地震速度和衰减的影响。 在地震学方面，他们将测试矿物物理学小组提供的关于全球地震波形数据集的可能参数化，这些数据集将在本项目期间收集，并根据文献汇编的地壳影响进行校正。

EAR-0001965Romanowicz In this collaborative project, the investigators aim at making progress on how to resolve lateral variations in water content between oceans and continents in the upper mantle, an issue of importance for our understanding of evolution and dynamics of the continental lithosphere. To this effect, they will combine seismological and mineral physics tools. On the mineral physics side, they will work on finding a suitable parameterization through which the effect of water on seismic velocity and attenuation is properly accounted for. On the seismology side, they will test possible parameterizations provided by the mineral physics group on a global seismic waveform dataset, which will be assembled during the course of this project and corrected for crustal effects, as compiled from the literature.
