Hydrate before and after dissociation. (a) Core UTCW J25R 9 × 1–4 (68–70 mbsf) immediately after splitting the core liner on the ship. (b) Yellow patches within frozen hydrate. (UTCW J25R, 56 mbsf). The sediment-filled fracture is due to hydrate breakage during rotary drilling. The hydrate was broken and the pieces not containing sediment contamination were dissociated. (c) The same hydrate following dissociation and centrifugation, showing oil (top), a partially suspended mix of oil and water(middle) and a fine powder residue of loose dolomite grains (bottom).
