Depth distributions for estimated in situ porosity, thermal conductivity, and temperature at Site C0002. a Grain thermal conductivity at 2.29 W/mK. b Grain thermal conductivity at 2.84 W/mK. The red and orange lines are values estimated with m = 2.52 and 2.00, respectively. The blue circles are in situ porosity values calculated from density log data. The green circles are core porosity values measured onboard. The dark green triangles are the porosity values for cuttings measured onboard. Blue squares are in situ temperature measurements. Gray bands at 200–400 mbsf depth represent the hydrate zone
