IODP Expedition 385 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.纵波速度（P-wave velocity）数据的采集工作基于未受扰动的沉积物截面半块开展：采用安装于卡口装置中的成对压电换能器（piezoelectric transducers），沿JRSO定义的y轴和/或z轴将换能器插入软沉积物中完成测量。本报告涵盖y轴和/或z轴方向的纵波速度、卡口间距、换能器间传播时间以及初至拾取结果。
