Figure F13. A. Catwalk scan of Core 201-1230A-26H. Average temperature of the core liner is ~20°C. The cold spot is 15.7°C. B. Core 201-1230A-26H split at the location of the core liner cold spot. Visual (left) and infrared (right) images were both taken with the IR camera. Average temperature of the core sediment is ~15°C. The cold spot is -1.7°C. C. The same section after subsampling for disseminated hydrate. Visual (left) and infrared (right) images were both taken with the IR camera. Average temperature of the core sediment is ~15°C. The minimum temperature recorded after subsampling the cold spot, reaching -3.2°C, was even lower than the split-core image.
