Figure F36. Plots of pressure, temperature, and vertical acceleration (top panel) and ship heave vs. time and vertical acceleration (bottom panel) recorded by the temperature-dual-pressure probe penetrometer, Site U1402. The tool is released and falls under its own weight at E. The tool is driven into the formation at F. Pumps are turned off and dissipation begins at G. Despite significant ship heave, the penetrometer, which is embedded in the formation, records no movement during the dissipation phase. This indicates that the Motion Decoupled Hydraulic Delivery System has successfully decoupled from the penetrometer. Letters correspond to Table T11.
