IODP Expedition 346 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（caliper system）上的成对压电换能器（piezoelectric transducers），针对以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、圆柱体试样，完成P波速度（P-wave velocity）数据的测量。配套报告涵盖沿X、Y和/或Z方向的P波速度、换能器间距、换能器间传播时间以及初至波拾取结果。
