Daily report for IODP Expedition 311, October 4, 2005
LOCATION: Site U1327 (CAS-01B)
SCIENCE UPDATE: Coring at Site U1327 continued throughout the day to the target depth of 300 mbsf. The lowermost IR anomalies (inferred gas hydrate) were observed in Core U1327C-27X at ~220 mbsf, coincident with the depth of the BSR. Additional temperature measurements were made using the DVTPP probe at 170.4, 218.5, and 300.0 mbsf. After completing Hole U1327C and displacing it with weighted mud, we offset 15 m to the northeast to spud a dedicated tool hole (Hole U1327D). Two APC cores were taken to 16.4 mbsf for ultra-high resolution sampling for pore water and headspace geochemistry, and microbiological analyses. By midnight, the hole was washed down to 83.0 mbsf and the first PCS was deployed (Core U1327D-3P), which returned without pressure.
