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.本数据集采用安装于测径仪系统上的成对压电换能器，对以JRSO定义的x轴为基准的原状岩芯半段，以及沿x、y或z轴方向的离散立方体与圆柱体试样开展测量，获取纵波速度（P-wave velocity）数据。所附报告涵盖沿x、y及/或z方向的纵波速度、测径仪间距、换能器间传播时间以及初至拾取结果。
