Description:
This dataset reports the isotope composition (carbon and oxygen isotopes) of planktonic foraminiferal (Trilobatus sacculifer), extracted from sediment samples from IODP Site U1459. The analyzed samples have a temporal coverage from the late Pliocene to the early Pleistocene (4 - 2 Ma), and were obtained from the Perth Basin (offshore southwestern Australia). Therewith, Site U1459 is ideally situated to record changes in Leeuwin Current dynamics, and this dataset has been obtained to study Leeuwin Current intensity on orbital glacial-interglacial timescales across the Plio-Pleistocene boundary. All samples were measured using a Finnigan MAT 251 gas isotope ratio mass spectrometer connected to a Kiel III automated carbonate preparation device at the Center for Marine Environmental Sciences (MARUM), between 2018 and 2021.
