NSF EarthScope MT-TA

Long-period magnetotelluric survey of approximately the northern two-thirds of the United States, carried out through a cooperative agreement between the Incorporated Research Institutions for Seismology (IRIS) and Oregon State University (OSU). Land permitting, data acquisition, quality control, and field processing were carried out in partnership with several different organizations over the course of this survey, including University of Utah, Zonge International Geophysical Services and Equipment, and Green Geophysics with project management and instrument/engineering support from IRIS/OSU and Chaytus Engineering, respectively. These efforts were funded by the National Science Foundation through the following EarthScope USArray-related awards to IRIS: EAR-0323309 "Collaborative Research: EarthScope-Acquisition, Construction, and Facility Management (USArray)", EAR-0323311 "Collaborative Research: EarthScope-Facility Operations and Maintenance (USArray)", EAR-0733069 "Collaborative Research: EarthScope Facility Operation and Maintenance (FY2008-FY2013) (USArray)", and EAR-1261681 "Seismological Facilities for the Advancement of Geoscience and EarthScope".本数据集源自针对美国北部约三分之二区域开展的长期大地电磁测深（magnetotelluric survey）调查，该调查由美国地震学联合研究机构（Incorporated Research Institutions for Seismology，IRIS）与俄勒冈州立大学（Oregon State University，OSU）通过合作协议联合推进。本次调查在完成土地许可办理后，联合犹他大学、Zonge国际地球物理服务与设备公司、格林地球物理等多家机构共同开展了数据采集、质量控制与野外数据处理工作，其中项目管理与仪器/工程支持分别由IRIS/OSU以及Chaytus Engineering提供。本项目相关工作由美国国家科学基金会（National Science Foundation）通过以下面向IRIS的EarthScope USArray相关资助项目提供资金支持：EAR-0323309《合作研究：EarthScope——数据采集、建设与设施管理（USArray）》、EAR-0323311《合作研究：EarthScope——设施运行与维护（USArray）》、EAR-0733069《合作研究：EarthScope设施运行与维护（2008财年-2013财年，USArray）》以及EAR-1261681《推动地球科学与EarthScope发展的地震学设施》。

背景概述

该数据集是NSF EarthScope USArray项目中的大地电磁可移动和骨干阵列数据集，覆盖了美国北部约三分之二的区域，时间跨度为2006年至2018年。它由美国国家科学基金会资助，通过IRIS和俄勒冈州立大学等机构合作执行，提供了长周期大地电磁测量数据，用于地球深部结构研究，数据可通过EarthScope Data Center公开访问。
