JA Daily Science Report for Expedition 306, 11 March 2005.


SCIENCE UPDATE: Cores 306-U1312A-1H to 14H (0-138.43 mbsf; 104% recovery) are mainly composed of nannofossil ooze with varying amounts of planktonic foraminifers, and only very minor amount of siliciclastic material. Most sediment in Core 1H is characterized by brownish (10YR 8/3, 10YR 7/3, 2.5Y 7/4) sediments whereas the rest of the cores are dominantly white (N9) with greenish (5Y 6/3) intervals. The Bruhnes/Matuyama boundary was identified in Core 2H.
