IODP Expedition 320T 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.本数据集采用全岩芯多传感器测井仪（Whole-Round Multisensor Logger, WRMSL），通过安装在测径系统（caliper system）上的成对压电换能器（piezoelectric transducers），对完整岩芯段开展纵波速度（P-wave velocity）测量。岩芯回收过程中发生的孔隙流体脱气与微破裂现象，可能对本次测量结果造成干扰。本报告包含x-y平面内的纵波速度数据，以及换能器间距与声波传播时间（traveltime）相关参数。
