Weather: Overcast
Site: C0006 (NT1-03) (33°01’ N, 136°47’ E)

Hole conditions required abandoning Hole C0006F at a final depth of 603 meters below seafloor (mbsf). After determining that Hole C0006F was unsafe to drill, we determined that Site C0006 would present the same risks and problems for coring at any further hole intended to penetrate below 600 mbsf. Time, operational, and scientific constraints are being evaluated to determine the alternative operations required achieving the scientific targets at this site - Site NT1-03A (see Expedition 316 Prospectus) has been chosen as the best alternative. Pull out of the hole, Spot drilling fluid, trip pipe and recover Borehole Assembly were completed, the ROV was launched in order to deploy transponders below the current, and the Chikyu is currently being repositioned and transponders calibrated.
