IODP Expedition 371 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.本数据集采用安装于卡钳系统上的成对压电换能器（piezoelectric transducers），针对未扰动的岩心段半块（采用JRSO定义的x轴）以及离散的立方体、圆柱体岩样（采用x、y或z轴）开展了纵波速度（P-wave velocity）测试。本报告涵盖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。
