Radiolarian data from the submarine Vityaz Ridge, Northwest Pacific, for biostratigraphic and paleoceanographic reconstructions

Abstract

Radiolaria are marine siliceous microfossils used to reconstruct paleoceanographic and paleoclimatic events. This report presents a dataset obtained from radiolarian analysis for the biostratigraphic and paleoceanographic reconstructions of the submarine Vityaz Ridge and the Kuril-Kamchatka Trench paraxial zone. Data were obtained from dredge samples collected during the 4th cruise of the R/V Akademik A. Nesmeyanov in 1984 and during the 37th, 41st, and 52nd cruises of the R/V Akademik M. A. Lavrentyev in 2005, 2006, and 2010, respectively. Both new and previously published data on distribution of the Pleistocene radiolarian zones in the North Pacific are presented in this report.
