Figure F4. (A) Raw and (B) de-tided pore fluid pressures recorded in the borehole observatory in Hole C0002G. Pore pressure was monitored in a screened interval at 757–780 mbsf in Kumano Basin sediment (red), and in an open hole from 937 to 980 mbsf in the uppermost accretionary prism (brown). Seafloor hydrostatic pressure is shown for reference (blue). The formation pressures exhibit clear responses to drilling activity and mud losses in the riser Hole C0002F and sidetracked Hole C0002N.
