JA Daily Science Report for Expedition 306, 3 April 2005.

LOCATION: En route to Site U1314 (GAR-1B)

SCIENCE UPDATE:

The cored interval at Hole U1313D comprises late Pliocene to Holocene biogenic and terrigenous sediments. At Hole U1313C, the lithology below Core 14H is predominantly white (N9) nannofossil ooze. This hole exhibits relatively less bioturbation and fewer numbers of dropstones or ice rafted debris than Holes U1313A and B. Pyrite streaks are common. The Matuyama/Gauss and Gauss/Gilbert boundaries were identified at 110.5 and 153.8 mbsf in Hole U1313C.
