IODP Expedition 359 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.本数据集的纵波速度（P-wave velocity）数据通过如下方式测得：借助安装于卡钳系统（caliper system）上的成对压电换能器（piezoelectric transducers），对以JRSO定义的x轴为基准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开展测试。配套报告包含沿x、y和/或z方向的纵波速度、卡钳间距、换能器间传播时间以及初至拾取（first arrival picks）结果。
