IODP Expedition 345 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.本数据集的纵波速度（P-wave velocity）数据，通过安装于测径系统的成对压电换能器（piezoelectric transducers），借助全断面多传感器测井仪（Whole-Round Multisensor Logger, WRMSL）对全岩芯断面进行测量获取。测量过程可能会受到岩芯取芯阶段孔隙流体脱气与微破裂现象的影响。本次提交的报告涵盖x-y平面内的纵波速度数据，以及换能器间的间距与声波传播走时。
