PRESENT ACTIVITY: Update as of 0800 hr 28 March 2009   Coring in Hole U1332C from 45.5 mbsf after spudding hole at 0105 hr this morning. We will spot core in this hole to fill in gaps in the record for Site U1332.  Once overlap is complete, we will move to PEAT-3C.

CORING: Cored U1332B-7 to 13H (48.1 mbsf to 100.6 mbsf) with an average recovery of 109.0%. Cored 14X to 18X (100.6 mbsf to 148.6 mbsf) with an average recovery of  60.8%. Pull out of the hole at 2130 hr and cleared the seafloor at 2230 hr.  Space out and offset vessel 30 m north of Hole U1332B. Ran in the drill string at 2230 hr in preparation for spudding Hole U1332C.
