IODP Expedition 395 Thermal conductivity

Thermal conductivity was measured using the heated needle method in either full-space needle configuration (soft/saturated sediments) or half-space needle configuration (harder materials) of a TeKa Berlin TK-04 thermal conductivity meter. Heat is applied to the sample and then thermal equilibrium is sought. The heating and equilibration curve is reduced to derive the thermal conductivity value. Raw data are stored if a user wishes to do off-line or postexpedition reduction.本数据集的热导率（thermal conductivity）测试采用加热针法，测试仪器为TeKa Berlin TK-04型热导率仪，可根据样品类型选用全空间针状探头配置（适配软质/饱和沉积物）或半空间针状探头配置（适配硬质材料）。向样品施加热量后，等待热平衡建立；通过对加热与平衡曲线进行数据约简，即可推导得到热导率数值。若用户需开展离线或野外作业后的数据约简工作，可留存原始数据以供使用。
