JA Daily Science Report for Expedition 305, 27 January 2005.
SCIENCE UPDATE: Cores 305-U1309D-152R to -154R (746.2 to 757.8 mbsf, 41% recovery). Core 305-U1309D-152R was a low recovery interval of deformed gabbroic breccia. The last core of our third bit run (Core 305-U1309D-153R) returned to predominantly undeformed medium- to coarse-grained gabbro with a few diabase fragments. The first core cut with a new bit (Core 305-U1309D-154R) is diabase.
