Simple Summary Phylum Retaria and Phylum Cercozoa consists of the siliceous planktonic organisms, commonly referred to as Radiolarians, were investigated from 200 m depth to the surface in the eastern Indian Ocean (80.00°–96.10° E, 10.08° N–6.00° S) during

This paper presents first comprehensive account of radiolarian taxa from the Pleistocene sequence of the Antarctic region. On the basis of 54 samples from the piston core KH94-4-AMR-2PC, 71 well-preserved radiolarian species were identified and illustrated.

The purpose of this study is to synthesize the radiolarian assemblages in the sediment samples south of 60°S in the Southern Ocean in terms of their taxonomic composition and paleoceanographic distribution. The radiolarian assemblages were examined from

This study discusses three species of Stylotrochus recently observed in small numbers in six cores from the southern Indian Ocean and seven in the Bellingshausen Basin. It describes their geographical and chronological distributions and relates them to
