Drilling objectives at the site were to obtain a high-resolution Pliocene–Quaternary environmental record. Preliminary shipboard investigation indicated that the mean sedimentation rate at Site U1304 is very high (14.9 cm/k.y.) and calcareous nannofossils are abundant and show excellent preservation (see the “Expedition 303 summary” chapter). We investigated calcareous nannofossils in samples from the uppermost 30.08 meters composite depth (mcd). The primary objective of this study is to record the variations in relative abundance of calcareous nannofossils and to provide information for interpreting late Quaternary environmental changes in the region.
