XML Database for Magnetotelluric Transfer Functions

该项目将通过将历史大地电磁数据组织到一个公开可用和可搜索的数据库中，为地球科学界提供服务。目前，来自历史观测活动的大地电磁数据并不广泛或容易获得。因此，计划实验的研究人员通常不知道这些数据，除非通过已发表的文献，否则只能非常有限地（或没有）访问来自相同或附近地区的先前数据。更完整和自由地获取这些先前的结果将是规划观察运动的重要资产，并将提高研究成果。大地电磁学是一种地球物理方法，通过测量地球表面的自然地磁和地电场变化来推断地球的地下电导率。大地电磁资料有助于研究地球深部地壳结构，调查地壳和地幔中硅酸盐熔体的分布，以及地震前兆的研究。这些数据的商业用途包括石油和天然气勘探、地热勘探、矿产勘探和地下水监测。

This project will provide a service to the Earth Science community by organizing historic magnetotelluric data into an openly available and searchable database. At present, magnetotelluric data from historical observational campaigns are not widely or easily available. Thus, a researcher planning an experiment is typically unaware of these data, with very limited (or no) access to previous data from the same or nearby areas, except through the published literature. More complete and free access to these previous results would be a great asset in planning an observational campaign and would enhance the outcomes of research.Magnetotellurics is a geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface. Magnetotelluric data enable studies of Earth's deep crustal structure, investigating the distribution of silicate melts in the crust and mantle, and earthquake precursor research. Commercial uses of the data include oil and gas exploration, geothermal exploration, mineral exploration, and groundwater monitoring.
