Notes: 1 = cutting shoes shown in Figure F2. 2 = ship local time. 3 = initial pressure after correcting final pressure to 14 psi. 4 = expected pressure assuming hydrostatic loading. 5 = some cores (*) collected a 1.00-m core under pressure and additional sediment in the extended shoe. 6 = total gas including air trapped in the tool during deployment. 7 = transducer not operating, pressure measured by gauge after potential loss of gas (air). 8 = entire gas volume consisted of air. 9 = maximum estimate of core length. 10 = an unknown amount of gas was lost at high pressure when the port clogged. 11 = total gas volume includes significant air (>100 mL). 12 = an unknown amount of gas was lost at low pressure. Chr = Christensen auger shoe with carbide cutters. RBI-t = Rock Bit International taped auger with polycrystalline diamond compact cutters. RBI-s = Rock Bit International standard with polycrystalline diamond compact cutters. ND = not detected.
