Figure F25. A. Thermal conductivity measurements (needle-probe method) show near-constant values through Unit I, with a sharp increase across the slope apron-wedge sediment interface at 216 mbsf. The value at 206 mbsf (0.68 W/m/°C) is an outlier. It probably represents measurement in an unfilled core liner. B. Overlapping mean-normalized thermal conductivity and bulk density profiles illustrate that water content is the primary determinant of downhole thermal conductivity variation.
