IODP Expedition 395 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.本数据集的取芯方位数据，系在采用先进活塞取芯器（advanced piston corer, APC）开展取芯作业期间于井下测得，所用定向工具为Minex FlexIT或Icefield MI-5取芯定向仪。此类工具可采集磁场强度与方位、三轴加速度计数据以及工具温度数据。
