After overcoming problems with a hydraulic ram that caused the moonpool doors to fail to open, Seacore’s drilling and reentry template (DART) was deployed on an American Petroleum Institute (API) drill string (used as conductor pipe for this expedition) to just above the seabed. From 1335 h, a seabed survey around the position of the first site was conducted using the downpipe underwater camera. A suitable site was located ~2 m from the planned position, and the DART was placed on the seabed with 8 T of weight. After removing the camera, the HQ (piggyback) drill string was run through the API conductor to the seabed and coring operations in Hole M0005A commenced. The first core arrived on deck at 2000 h. Thereafter, coring continued with difficult barrel latching, and short core runs were used to avoid drilling rather than coring until the best coring parameters were established. The first cores displayed large cavities, and recovery was poor. Core barrel jams and problems with blocked bit–related mislatching led to slow progress in this hole. When reentering the hole after one particular drill string trip to remove a core blockage from the bit, coring appeared to recommence at 10.4 meters below seafloor (mbsf). Good core was obtained, and it appeared that the borehole had been restarted in a deviation or had avoided a previous deviation. This was taken as the start of a new hole, Hole M0005B, at 1840 h on 8 October.
