JA Daily Science Report for Expedition 308, 2 July 2005


LOCATION: Site U1322    


SCIENCE UPDATE: We spent the day drilling Hole U1322D from 40 mbsf to total depth of 175 mbsf. We deployed the T2P probe 4 times (at 40, 70, 100, and 134 mbsf) and the DVTP-P probe once at 175 mbsf. The first two T2P deployments were successful. The third T2P deployment had a partially successful reading: the tip read hydrostatic pressures, while the shaft read elevated pressures. On the fourth T2P measurement the shaft was bent and the data was poor. The final DVTP run was very successful. Cores, taken largely for whole round geotechnical analyses, were taken at 40, 70, and 100 mbsf. The lithologies encountered were mainly greenish clays, similar to what was described in Hole U1322B. Science operations were terminated at 16:00 hr, and as of 2400 hr, the JOIDES Resolution had left the location of Site U1322 and was steaming on its way to Panama.
