Collaborative Research: Development of Automated Quality Control and Processing for Earthscope Magnetotelluric Data

大地电磁法测量自然变化的电场和磁场，以确定地下电导率。岩石的整体电导率主要取决于一小部分高导电材料，如部分熔体、水溶液、金属导体和石墨。流体和部分熔体的分布是了解地球内部结构和物理状态的关键组成部分，因此地球镜计划获取美国各地的大地电磁数据。如此大量的数据需要自动化的实时管理、质量控制和处理工具，以优化MT传递函数的最终估计，其他人将使用这些工具来开发电导率模型。我们正在为这两项任务开发软件。

The magnetotelluric method measures naturally varying electric and magnetic fields in order to determine subsurface electrical conductivity. Bulk electrical conductivity of rocks depends mostly on small fractions of highly conductive materials such as partial melt, aqueous fluids, metallic conductors, and graphite. Fluid and partial melt distributions are key components to understanding the structure and physical state of the Earth's interior, so Earthscope has a plan to acquire MT data across the United States. Such a large volume of data requires automated real time management and quality control and processing tools for optimal final estimates of MT transfer functions that will be used by others to develop conductivity models. We are developing the software for these two tasks.
