During Leg 177 of the Ocean Drilling Program (ODP), a well-preserved middle Eocene to lower Miocene sediment record was recovered at Site 1090 on the Agulhas Ridge in the Atlantic sector of the Southern Ocean. This new sediment record shows evidence of

Detailed radiolarian biostratigraphy in the Plio-Pleistocene was analyzed by using samples from IODP Site U1340 that was drilled to a core depth of 604 m in the southern Bering Sea. A total of 227 species belonging to 102 genera were identified. Based

The analyses of abundant and well-preserved late middle Eocene to early Oligocene radiolarian assemblages were carried out on ODP Site 1090 (Leg 177) sediments in the Atlantic Sector of the Southern Ocean. A total of 83 radiolarian events are identified

Cleve’s material from the Swedish Expedition to Spitsbergen in 1898 has been re-examined and lectotypes and some paralectotypes have been established for three spumellarian species, eight nassellarian species, and three phaeodarian species. In addition,
