Abstract
We present an extensive dataset on the modern radiolarian distribution in new samples of the surface sediments from the North Pacific and Bering Sea north of 38°N. Samples came from the RV Sonne cruises SO201-2 and SO202-1 in 2009 within the KALMAR II and INOPEX projects (Dullo et al., 2009, Gersonde, 2012). We have analyzed 46 surface sediment samples from the multicorers following the standard laboratory treatment, preparation of the micropaleontological slides, and counting of the radiolarian tests under the microscope (Abelmann, 1988, Zielinski et al., 1998). List of species consists of two hundred eight radiolarian taxa. During the routine counting, we made the microphotographs of radiolarians. Our dataset consists of three data files: 1) coordinates of stations, 2) list of the radiolarian taxa with microphotographs, 3) data on the raw counts of the radiolarian tests per 1 slide, and calculated total radiolarian abundances and taxa percentages.
