3Cx3C active seismic dataset in 3D configuration, acquired in Scheemda, Groningen province, the Netherlands

This dataset contains 3D seismic data with 3-component sesmic sources (vertical forces and two cross-polarized horizontal forces) and 3-component receivers (673x3=2028 receiver channels), acquired in Scheemda, Groningen province, the Netherlands. The electric linear-motor-system (LMS) vibrator of Seismic Mechatronics in vertical and horizontal modes was used as vertical- and horizontal-force sources, respectively. 3C geophone nodes (676x3 = 2028 receiver channels) are used in the data acquisition. This survey was mainly intended for imaging spatially varying subsoil density using a full-waveform inversion technique as part of Yusuke Kawasaki's PhD project.

本数据集包含三维地震数据（3D seismic data），采集自荷兰格罗宁根省斯基姆达（Scheemda）地区。本次采集所用震源为三分量地震震源（3-component seismic sources），涵盖垂直力震源与两个正交极化水平力震源；接收器为三分量检波器接收器（3-component receivers），共计673组×3=2028个接收道。数据采集采用地震机电公司（Seismic Mechatronics）的电动直线电机系统（LMS）振动源，分别以垂直模式与水平模式作为垂直力震源与水平力震源。本次采集使用了三分量检波器节点（3C geophone nodes），共计676组×3=2028个接收道。本勘探项目作为川崎裕介（Yusuke Kawasaki）博士研究项目的一部分，核心目标为利用全波形反演（full-waveform inversion）技术对空间变化的地下土层密度开展成像工作。
