SCIENCE UPDATE: The last core of Expedition 312 (234R) was on deck at 0315 hr and recovered 25 cm of moderately altered fine grained aphyric to cryptocrystalline basalt cut by gabbro from 1502.5 to 1507.1 mbsf. After recovery of Core 234R the bit had accumulated 53 hr of rotation. The hole was conditioned and a 110 barrel sweep of high viscosity mud was pumped. The pipe was then tripped for the final bit change in preparation for logging.
