Weather: Fine but Cloudy
Site: C0001 (NT2-03) (33°14’ N, 136°42’ E)
Science Operations on Deck: Continued drilling with RCB assembly with center bit at the Hole C0001I. While reaming 433 to 467 mbsf, had pipe stuck which required 700 kN for freeing pipe. After escaping from this, abandoned the well and retrieved transponders.

Science Operations in Labs: Started writing Site Summary reports of C0001. Continued NGR re-measurement for the split halves. Completed XRD analyses.
