Biostratigraphy of sediment core CRP-3 from the Ross Sea, Antarctica, supplement to: Harwood, David M; Bohaty, Steven M (2001): Early Oligocene siliceous microfossil biostratigraphy of Cape Roberts Project Core CRP-3, Victoria Land Basin, Antarctica. Terra Antartica, 8(4), 315-338

Early Oligocene siliceous microfossils were recovered in the upper c. 193 m of the CRP-3 drillcore. Although abundance and preservation are highly variable through this section, approximately 130 siliceous microfossil taxa were identified, including diatoms, silicoflagellates, ebridians, chrysophycean cysts, and endoskeletal dinoflagellates. Well-preserved and abundant assemblages characterize samples in the upper c. 70 m and indicate deposition in a coastal setting with water depths between 50 and 200 m. Abundance fluctuations over narrow intervals in...
