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

The study of circum-Antarctic sediment samples from south of 60 °S reveals the presence of a distinctive coastal assemblage in shallow waters around Antarctica. This assemblage consists primarily of just two species, Rhizoplegma boreale (Cleve) and Phormacantha

A characteristic indicator of Antarctic and Arctic waters today is the sinistrally-coiled Globigerina pachyderma. By tracing this indicator back through the Neogene, it is possible to demonstrate major expansions of cold-water isotherms not only during
