ElectroMagnetic Studies of the Continents (EMSOC): Data and Interpretation Facilities for Research and Instruction

该合同提供资金，用于获得GEOTOOLS计算机程序源代码的无限制CPU许可证，该程序集成了用于解释大地电磁(MT)数据的最先进软件、国际公认的标准格式的关系数据库以及将MT数据转换为标准格式的实用程序。GEOTOOLS计划已被在MT地区工作的地球物理研究社区作为标准采用，加拿大和墨西哥的工作人员已经可以使用该计划。PI将以极大的教育折扣获得许可证，并将其提供给美国所有感兴趣的教育组织。MT社区使用自然电磁能量来成像地球内部结构的性质，如导电性。MT数据的分析是非常计算机密集的，该领域的进展受到多种数据格式的阻碍，这使得数据共享复杂化，3-D数据可视化困难，以及数据与不同小组开发的不兼容分析软件程序的接口问题。对GEOTOOLS计划的访问将为整个北美带来统一、灵活的MT数据分析环境。

This award provides funds for the acquisition of an unlimited cpu license to the source code of the GEOTOOLS computer program which integrates state of the art software for interpreting magnetotelluric (MT) data, a relational data base in standard, internationally accepted format, and utilities for converting MT data to standard format. The GEOTOOLS program has been adopted as standard by the geophysics research community working in the MT area and is already accessible to workers in Canada and Mexico. The PI will obtain the license at a very substantial educational discount and will provide it to all interested educational organizations in the U.S. The MT community uses natural electromagnetic energy to image internal Earth structure in terms of properties such as electrical conductivity. Analysis of MT data is very computer intensive and progress in the field has been inhibited by diverse data formats that complicate data sharing, by difficulties of visualizing the 3-D data, and by the problem of interfacing data with incompatible analysis software programs developed by different groups. Access to the GEOTOOLS program will result in a uniform, flexible MT data analysis environment for all of North America.
