007 December 5 (Day 20)
Weather: Fine but Cloudy
Site: C0001 (NT2-03) (33°14’ N, 136°42’ E)
Science Operations on Deck: Despite of repeated washing and reaming, borehole condition of the Hole C0001H did not improve. At 13:00 p.m., abandoned the hole and pulled-out-of-hole the coring assembly to the seafloor. Moved 60 m eastward and spud a new hole (Hole C0001I) at 16:00 p.m. Jetted in down to 70 meters below seafloor (mbsf), then drilled down to 303.0 mbsf with RCB assembly with center bit by 24:00.

Science Operations in Labs: Restarted XRD analysis, which was repaired on 4 Dec by replacement of high-voltage unit. Continued NGR measurements using split halves. Advanced measurements mainly on inorganic chemistry is ongoing. Scientific Party has almost finished the first drafts of the Methods chapter of the Expedition Report, which will be reviewed by Co-Chief Scientists and Expedition Project Manager.
