IODP Expedition 329 P-wave velocity bayonet (section)

P-wave velocity data were measured on undisturbed section halves using pairs of piezoelectric transducers mounted in bayonets that are inserted into soft sediment along the JRSO-defined y-axis and/or z-axis. Report includes P-wave velocity in y and/or z direction, bayonet separation, traveltime between transducers, and first arrival picks.本数据集的纵波速度（P-wave velocity）数据采集自未受扰动的沉积物岩心半段，采用成对安装于卡口套筒内的压电换能器（piezoelectric transducers）完成测量：将套筒沿JRSO定义的y轴和/或z轴插入软沉积物中。报告包含沿y轴和/或z轴方向的纵波速度、卡口套筒间距、换能器间的声波传播时间以及初至拾取结果。
