Data report: late Pliocene to early Quaternary calcareous nannofossils, IODP Expedition 323 Site U1341, Bering Sea¹

Abstract

We performed semiquantitative analyses of late Pliocene–early Quaternary calcareous nannofossil assemblages in samples from Hole U1341B, recovered on the Bowers submarine ridge during Integrated Ocean Drilling Program Expedition 323 to the Bering Sea (July–September 2009). The record is characterized by very low abundances and frequent barren intervals, which have hampered our attempts of locating standard and high-latitude calcareous nannofossil biostratigraphic events. However, we have narrowed a horizon in which noted changes in the assemblage composition can be correlated to other records in the North Pacific.
