Coompana Predrill Magnetotelluric Data

Magnetotelluric (MT) measures the natural variations of the Earth magnetic and electrical (telluric) fields. MT data were collected at six sites in the Coompana region in Apr 2016, and at 40 locations at eight proposed drilling sites in Feb 2017. The instrument used was Phoenix Geophysics equipment (MTU-5A, MTC-150L and PE5 electrodes). Time series data were processed into frequency domain using remote reference and Robust Processing scheme. After quality assurance, processed data were exported to industry-standard EDI files.大地电磁法（Magnetotelluric，MT）测量地球磁场与电场（大地电场）的自然变化。2016年4月，在Coompana地区的6个站点采集了MT数据；2017年2月，于8个拟议钻井场地的40个位置开展了补充采集。所用仪器为Phoenix Geophysics公司的设备，包括MTU-5A、MTC-150L仪器及PE5电极。时间序列数据通过远参考法（remote reference）与稳健处理方案（Robust Processing scheme）转换至频域。经过质量保证后，处理后的数据导出为行业标准的EDI文件。
