IODP Expedition 369 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.本数据集包含通过卡钳式测试系统（caliper system）上安装的成对压电换能器（piezoelectric transducers）测得的P波速度（P-wave velocity）数据，测试对象分为两类：一类为以JRSO定义的x轴为基准的未受扰动岩心半段，另一类为以x、y或z轴为基准的离散立方体与圆柱试样。本报告涵盖x、y及/或z方向的P波速度、测径间距、换能器间传播时间以及初至拾取结果。
