Sea Trials Transit

Daily Science Report for 19 February 2009

LOCATION: On Site U1330 (Ontong Java Plateau)

SCIENCE UPDATE: Logging activities concluded early morning with the last run of the MSS tool string and final wireline heave compensator testing. All logging results are currently being processed and analyzed by the shipboard logging team. After the drill string was pulled out of Hole U1330A, the Rotary Core Barrel (RCB) bottom hole assembly was exchanged with an Advanced Piston Core (APC) assembly, and the drill string was reassembled, piston coring of the new Hole U1330B began in the early evening. By midnight, four APC cores were recovered to 35.2 mbsf (with recovery rates of ~101% except for Core 4H, which encountered a problem with the flapper valve) and APC coring continued during the night.

The Readiness Assessment Committee continued with testing of various analytical and descriptive applications and USIO internal acceptance testing was ongoing as well.

Ship highlight of the day: Paleomagnetism Lab

Paleomagnetic and rock magnetic measurements are used to construct a magnetostratigraphy for each site and to study its paleomagnetic and tectonic history. The lab area was enlarged by 19%.
