JA Daily Science Report for Expedition 309, 25 July 2005


LOCATION: Site 1256


SCIENCE UPDATE: Recovery in Cores 93R to 96R (873.8 to 897.8 mbsf) increased slightly to 6 m (25%). At the end of Core 96R the bit had accumulated 52.1 hours of rotation so the pipe was tripped for a bit change. The rocks remain predominantly aphyric, cryptocrystalline to microcrystalline, slightly altered dark grey basalt sheet flows with some glass and altered hyaloclastite.
