IODP Expedition 368 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.本数据集借助安装于卡尺系统的成对压电换能器（piezoelectric transducers），在完整圆多传感器测井仪（Whole-Round Multisensor Logger, WRMSL）上对全直径岩心截面开展P波速度（P-wave velocity）测试。岩心回收过程中孔隙流体脱气与微破裂现象可能对测试结果造成影响。本次报告涵盖x-y平面内的P波速度，以及换能器间的间距与传播时长数据。
