Abstract:
Sediment cores from the South Pacific (Chile Fracture Zone) obtained during RV SONNE cruise SO213 (SOPATRA) in December 2011 allow us to reconstruct lateral changes in the subpolar gyres in the pelagic South Pacific over the last ~3.8 million years. This dataset comprises planktic stable carbon (δ13C) and oxygen isotope (δ18O) data as well as element/Calcium ratios from piston core SO213_08-2, which was recovered from the South Pacific (37°29.47 S 95°20.61 W) from 2172 m water depth. Measurements were performed on the planktic foraminiferal species Globigerinoides ruber, Globigerina bulloides, and Globorotalia inflata. Sampling and analytical studies were carried out from 0.365–11.965 m core depth at ~8 cm spatial resolution. The isotope analyses were performed on a Thermo Scientific MAT 253 mass spectrometer with an automated Kiel IV carbonate preparation device. The element/Calcium analyses were run on an ICP-OES, VARIAN 720-ES, with prior reductive and oxidative cleaning of foraminiferal tests.
