National Radioactive Waste Management Facility AEM Survey Logistics Report, AEM Data, and Laterally Constrained Inversion Results

In July 2022 an airborne electromagnetic (AEM) survey was flown over and around the proposed site of the National Radioactive Waste Management Facility near the township of Kimba in South Australia. The survey was commissioned by the Australian Radioactive Waste Agency, and was project managed by Geoscience Australia. The survey has Geoscience Australia airborne survey project number P5008.The survey was flown by Skytem Australia Pty Ltd using its SkyTEM312Fast AEM system. The survey was conducted on east-west lines at 500 m spacing, with a smaller central focus area of 100 m spaced lines, acquiring a total of 2,545 line kilometres of data. Skytem Australia Pty Ltd also processed the data.This data package includes the acquisition and processing report, the final processed AEM data and the results of the 1D laterally constrained inversion of the data to conductivity-depth estimates that was carried out by the contractor.

2022年7月，针对澳大利亚南澳州金巴（Kimba）镇附近拟议的国家放射性废物管理设施场址及其周边区域，完成了航空电磁（airborne electromagnetic, AEM）测量作业。本次测量由澳大利亚放射性废物署（Australian Radioactive Waste Agency）委托，澳大利亚地球科学局（Geoscience Australia）负责项目管理，项目编号为P5008。测量作业由Skytem Australia Pty Ltd使用其SkyTEM312Fast航空电磁系统完成，采用东西向测线布设，线间距为500米，并在中心区域设置了线间距100米的加密测区，总采集测线长度达2545公里。Skytem Australia Pty Ltd同时承担了本次数据的处理工作。本数据包包含采集与处理报告、最终处理后的航空电磁数据，以及由承包商针对数据开展的一维横向约束反演得到的电导率-深度估算结果。
