IODP Expedition 392 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数据，通过安装于井径系统（caliper system）的成对压电换能器（piezoelectric transducers），依托全岩芯多传感器测井仪（Whole-Round Multisensor Logger, WRMSL）对全岩芯段完成测定。该测量过程可能受岩芯取芯阶段孔隙流体脱气与微破裂效应的影响。本数据集配套报告包含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。
