XML Database for Magnetotelluric Transfer Functions

该项目将向地球科学界提供服务，将历史大地电磁数据组织到一个可公开使用和可搜索的数据库中。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，计划一项实验的研究人员通常不知道这些数据，除了通过已发表的文献之外，对相同或附近地区的先前数据的访问非常有限(或无法访问)。更全面、更自由地获取这些以前的结果将是规划观测活动的一大财富，并将增强研究成果。大地电磁是一种地球物理方法，用于根据对地球表面自然地磁场和地电场变化的测量来推断地球的地下电导率。大地电磁数据使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研究成为可能。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.
