Figure F20. Photos of CORK pressure logging systems prior to deployment from the Thomas G. Thompson during September 2004. A. Pressure logging systems for CORKs at Holes 1026B and U1301A. The original design was intended to place the pressure loggers in frames on the CORK heads, but this design was subsequently modified to place the loggers on separate frames on the submersible/ROV platform in the cone or on the seafloor. Each logging system has a hydraulic coupler that mates to individual pressure lines in the CORK head. B. Elevator system used to deploy pressure logging systems on Expedition 301 observatories.
