JA Daily Science Report for Expedition 312, 24 November 2005
LOCATION: Site 1256
SCIENCE UPDATE: Core 182R recovered 0.38 m of basalt cobbles from 1304.9 to 1309.7 mbsf (7.9%). Overall, the grain size of the rocks has decreased somewhat from the beginning of operations at Site 1256 on Expedition 312. The drop in recovery may be related to penetration of a near-vertical dike margin or thin highly fractured dikes but this interpretation remains tentative. At 0545 hr the bit had accumulated 50.5 hours of rotation so the pipe was tripped for a bit change.
