IODP Expedition 361 P-wave velocity caliper (section)

P-wave velocity data were measured on undisturbed section halves (JRSO-defined x-axis) and/or discrete cube and cylinder samples (x, y, or z-axis) using pairs of piezoelectric transducers mounted on a caliper system. Report includes P-wave velocity in x, y, and/or z-direction, caliper separation, traveltime between transucers, and first arrival picks.本研究针对纵波速度（P-wave velocity）数据开展测试：测试对象为原状试样半段（以JRSO定义的x轴为基准）以及离散立方体、圆柱体试样（沿x、y或z轴方向），测试采用安装于卡尺系统的成对压电换能器（piezoelectric transducers）完成。本数据集报告涵盖x、y和/或z方向的纵波速度、卡尺间距、换能器间传播时间以及初至拾取结果。
