JA Daily Science Report for Expedition 307, 30 April 2005


LOCATION: Site U1316


SCIENCE UPDATE: We arrived on site at 0415 hr, and the first core was on deck at 1120 hr. The upper 50m of Holes U1316A consists of late Pleistocene (Brunhes) silty clay with dropstones, underlain by a 3m layer of coral rudstone and floatstone and a further 5m of silty clay. Below this are Early Miocene sandy siltstones. XCB coring in the siltstones is going slowly, and this may require the addition of RCB coring to the original operations plan.
