IODP Expedition 396 P-wave velocity logger (whole round)

P-wave velocity data were measured on whole-round sections on the Whole-Round Multisensor Logger (WRMSL) using pairs of piezoelectric transducers mounted on a caliper system. Measurements may be affected by degassing of pore fluid and microfracturing during core recovery. Report includes P-wave velocity in x-y plane and distance and traveltime between transducers.本数据集的纵波（P-wave）速度数据，借助全岩芯多传感器测井仪（Whole-Round Multisensor Logger, WRMSL），通过安装于测径系统的成对压电换能器对完整岩芯段开展测量获得。测量过程可能受到岩芯回收阶段孔隙流体脱气与微破裂的影响。本报告涵盖x-y平面内的纵波速度，以及换能器间的间距与声波传播走时。
