IODP Expedition 392 Core orientation

Core orientation data were measured downhole during advanced piston corer (APC) coring, either by Minex FlexIT or Icefield MI-5 core orientation tool. These tools measure magnetic strength and orientation, 3-axis accelerometer data, and tool temperature data.岩心取向数据于高级活塞取芯器（advanced piston corer，APC）取芯作业期间通过井下方式测得，所用工具为Minex FlexIT或Icefield MI-5型取芯定向工具。此类工具可测量磁强度与岩心取向、三轴加速度计数据以及工具温度数据。
