(Table 1) Age and sedimentation rates of Pleistocene/Holocene sequences at DSDP Sites 86-580 and 94-611@en

The recovery from the North Atlantic (Site 611) of a continuous Pleistocene sedimentary record with a siliceous microfaunal component made it possible to compare the high-latitude abundance pattern of the radiolarian species Cycladophora davisiana in the Atlantic with that produced from analyses of a high-latitude record (Site 580) from the northwest Pacific. Previous studies had shown that the late Pleistocene (0-0.45 Ma) abundance variations of this species in these high-latitude regions were similar. […]
