Notes: Water depth at Hole U1326C is 1828 mbsl. P = Pressure Core Sampler (PCS), Y = Fugro Percussion Corer (FPC), E = HYACE Rotary Corer (HRC). * = based on X-ray imaging and gamma ray density profiling prior to degassing. † = last pressure recorded before data logger disconnected from corer autoclave. Temperature 2°–4°C unless otherwise noted. ‡ = pressure measured when autoclave pressure transducer connected to computer (PCS cores) or external gauge (PCS, FPC, HRC cores). Pressure measured at 7°C unless otherwise noted. — = no data.
