IODP Expedition 327 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.纵波速度（P-wave velocity）数据通过全圆多传感器测井仪（Whole-Round Multisensor Logger, WRMSL）在完整圆形岩心段上测得，测试采用安装于卡尺系统（caliper system）的成对压电换能器（piezoelectric transducers）。测试过程可能受岩心回收阶段孔隙流体脱气与微破裂作用的影响。本报告包含x-y平面内的纵波速度，以及换能器之间的间距与声波传播时间。
