2007 November 27 (Day 12)
Weather: Rain
Site: C0001 (NT2-03) (33°14’ N, 136°42’ E)
Science Operations on Deck: Continued RCB coring at the Hole C0001H from 296.5 meters below the seafloor (mbsf) to 397.5 mbsf. Round gravel of mudstone was observed, which is typical to borehole caving.
Science Operations in Labs: Recovery RCB cores is highly variable but quality is generally good enough to take samples for shore based experimental studies. Science Party continued to measure and described core samples. Physical property specialists estimated the thermal gradient based on downhole data (APCT3) and core thermal conductivity. It is high quality fundamental information about heat flow in Accretionary complex, which also helps temperature estimation for future riser drilling and long-term borehole monitoring. Scan images focusing on shear planes with high (dense) and low (porous) CT-values. Guidance to the Science Party about Expedition-related publication obligation was held, presented by Publication Assistant.
