Well preserved middle Miocene to Recent radiolarians were recovered from several sites in the Weddell Sea by ODP (Ocean Drilling Program) Leg 113. Low rates of sedimentation, hiatuses, and poor core recovery in some sites are offset by the nearly complete recovery of a late middle Miocene to late Pliocene section at Site 689 on the Maud Rise. Although a hiatus within the latest Miocene exists, this site still provides an excellent reference section for Antarctic biostratigraphy. A detailed radiolarian stratigraphy for the middle Miocene to late Pliocene of Site 689 is given, together with supplemental stratigraphic data from ODP Leg 113 Sites 690, 693, 695, 696, and 697. A refined Antarctic zonation for the middle Miocene to Recent is presented, based on the previous zonations of Hays (1965), Chen (1975), Weaver (1976b), and Keany (1979). The late Miocene radiolarian Acrosphaera australis n. sp. is described and used to define the A. australis zone, ranging from the first appearance of the nominate species to the last appearance of Cycladophora spongothorax (Chen) Lombari and Lazarus 1988.
