Table T16. Summary of pressure coring operations at Site U1325.
|17E||129.9||56||56||23.3||0||—||Core liner broke at core catcher|
|22Y||169.4||17||17||23.7||0||—||Valve did not close; sediments washed out of core|
|26E||197.4||28||28||24.0||0||—||Deformed liner prevented valve from closing|
|28P||206.1||46||46||24.1||0||—||PCS stuck beyond main bit; pipe trip required|
|5Y||217.6||0||0||24.2||21.7||22.0||Damaged core catcher; water core only|
Notes: Water depth at Site U1325 is 2195 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.
