Figure F25. Downcore temperatures from IR scans of Holes 1251B and 1251D. Strong positive anomalies in cores from both holes are sun illumination artifacts. The major negative anomaly in Hole 1251D is from hydrate recovered near the BSR that was not recovered in Hole 1251B (see also Fig. F26). APC = advanced piston corer, BSR = bottom-simulating reflector, XCB = extended core barrel.
