Shallow geo-electric dataset (ERT/IP/SP) of the Reykjanes geothermal area, Iceland

This dataset was acquired in September 2022 to characterize the shallow geo-electric features of the Reykjanes geothermal system. Electrical resistivity tomography (ERT), Induced Polarization (IP) and Spontaneous potential (SP), was measured on four profiles. Reciprocals were collected for the ERT profiles, needed for filtering and noise estimation, IP data is collected in the time domain. The SP data was collected along the same profiles but not simultaneously to avoid signal interference. The dataset includes: ERT and IP data as .csv files for both the normal (N_profile*) and Reciprocal (R_profile*) corrected SP data as .csv shapefile with the profile locations, and any necessary auxiliary files. The abovementioned data is always measured North-South and West-East, all profiles are measured with 5m electrode spacing.本数据集采集于2022年9月，用于表征雷克雅内斯（Reykjanes）地热系统的浅部地电特征。 本次研究在四条测线上开展了电阻率层析成像（Electrical Resistivity Tomography, ERT）、激发极化（Induced Polarization, IP）与自然电位（Spontaneous Potential, SP）测量。其中，电阻率层析成像测线采集了正反扫数据，该数据可用于后续滤波处理与噪声评估；激发极化数据采用时域采集方案；自然电位数据沿相同测线布设，但为避免信号干扰，未与前两类数据同步采集。 本数据集包含以下内容： 1. 对应正扫（N_profile*）与反扫（R_profile*）的电阻率层析成像与激发极化数据，均以.csv格式文件存储； 2. 经校正的自然电位数据，以.csv格式文件存储； 3. 包含测线位置信息的shapefile文件，以及所有必要的辅助文件。 上述所有测线均沿南北向与东西向布设，且所有测线均采用5米的电极间距进行数据采集。
