IODP Expedition 349 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.

研究人员将成对安装有压电换能器(piezoelectric transducers)的卡口装置，沿JRSO定义的y轴和/或z轴插入软沉积物中，于未扰动的剖面半块上测得纵波速度(P-wave velocity)数据。本数据集所附报告包含y轴和/或z轴方向的纵波速度、卡口装置间距、换能器间走时以及初至拾取结果。
