Airborne electromagnetic and magnetic survey data, Big Sioux aquifer, October 2015, Sioux Falls, South Dakota

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2015 along 769 line-kilometers over a 160-square-kilometer area that includes the Big Sioux aquifer between Sioux Falls and Dell Rapids, South Dakota, USA. Data were acquired with the CGG Resolve frequency-domain helicopter-borne electromagnetic system along with a cesium vapor magnetometer. Files included in this data release are: (1) raw and processed AEM and magnetic data; (2) processed AEM resistivity-depth inversions, and (3) a contractors report describing survey parameters, field operations, quality control, and data reduction procedures.

2015年10月，研究团队在美国南达科他州苏福尔斯与戴尔拉皮兹之间包含大苏族含水层的160平方千米区域内，开展了航空电磁（Airborne Electromagnetic, AEM）与磁法测量数据采集工作，测线总长度达769测线公里。本次数据采集采用CGG Resolve频域直升机载电磁系统，并配套铯蒸气磁力仪完成数据获取。本次发布的数据集包含以下三类文件：(1) 原始及预处理后的航空电磁与磁法测量数据；(2) 经预处理的航空电磁电阻率-深度反演结果；(3) 一份承包商编制的报告，内容涵盖测量参数、外业作业流程、质量控制方案以及数据归约流程。
