Expected pressure is the hydrostatic pressure assuming a pressure gradient of 1.467 psi/m. Observed pressure is that first recorded at the PCS sampling station. "* = Cores 995A-0P and 52P were deployed as blank (water) PCS runs that were not intended to recover core (see text). Push-in means that cutting shoe was not applied because these were samples taken in water, not in the sediment."
