Daily Report for IODP Expedition 311, October 10, 2005

 

LOCATION: Site U1327 (CAS-01B)

 

SCIENCE UPDATE: Hole U1327E was drilled as special wireline logging hole to a total depth of 300 mbsf, which was reached at 16:30 hr. Because of the continued high ship heave conditions (ranging from 2.5 to 3.5 m) it was decided to make only one log run with the non-standard IODP tool string of the HNGS-DIT-DSI, which will yield natural gamma, resistivity, and acoustic transit time data. Note that this tool string contains no caliper devices, which have been damaged in other holes on this expedition under similar ship heave conditions. By midnight we had completed the first run of this tool string from the loggers maximum total depth of 287 mbsf to the drill pipe which was set-back to 72 mbsf. The resistivity and acoustic log data from this survey appear to be of relatively high quality. After completing a short repeat wireline survey, we will prepare for transiting to Site U1328.
