Site M0078

Abstract

During International Ocean Discovery Program (IODP) Expedition 381, cores were recovered from two holes at Site M0078. In total, 20.27 days were spent on station, with an average core recovery of 88% for the site. Hole M0078A was drilled to 610.43 meters below seafloor (mbsf), and Hole M0078B was drilled to 55.85 mbsf. In Hole M0078A, the Fugro Wison Extended Piston (WEP) system was used to core the upper 75 m, and the Fugro Corer in push mode was used for the next 124 m, followed by the same corer in percussive mode for 25 m. The Fugro Extended Marine Core Barrel (FXMCB) (rotary) was used to core the final 386 m of the borehole. In Hole M0078B, the Fugro Corer in push mode was used throughout to the base of the hole at 55.85 mbsf.
