We reached refusal point (0 penetration) for HPCS coring at 79 meters below seafloor (mbsf), and began using the ESCS system. ESCS coring recovery and quality has improved, even in the relatively sandy materials we have been encountering at this site. Two APCT measurements and one DVTP measurement were collected. At about 4:30 AM there was a failure in the top drive lubricating pump motor and operations were suspended pending repair or replacement.
