JA Daily Science Report for Expedition 312, 25 November 2005


LOCATION: Site 1256


SCIENCE UPDATE: After washing to bottom (30 m of fill) rotary coring resumed with a new C-9 bit and Cores 183R to 185R recovered 1.12 m of basalt from 1309.7 to 1319.5 mbsf (11.4%). Penetration has dropped to 0.8 m/hr as we continue to core predominantly cryptocrystalline to microcrystalline basalts. Core 184R was recovered after only a one meter advance in 5 hours but with excellent recovery (92%). Hole conditions are good to excellent with smooth torque.
