IODP Expedition 360 P-wave velocity caliper (section/discrete)

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.本数据集的纵波速度（P-wave velocity）测量工作，采用安装于卡尺系统（caliper system）的成对压电换能器（piezoelectric transducers）完成，测量对象包括沿JRSO定义的x轴方向的原状岩心半段，以及/或沿x、y或z轴方向的离散立方体与圆柱体试样。本报告涵盖以下内容：x、y及/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（first arrival picks）结果。
