Abstract:
Proxy parameter of core MD03-2609: Isotope-geochemical were performed on the planktonic foraminiferal species Globorotalia truncatulinoides, Orbulina universa and Globigerinoides ruber. The foraminiferal specimens were selected from piston core MD03-2609, which was recovered from northwest of King Island (south of Australia; 39°24.17S 141°58.12E) from 2056 m water depth during R/V Marion Dufresne Cruise MD131 in 2003 (https://doi.org/10.17600/3200090). Sampling and analytical studies were carried out from ~1 to 398 cm core depth at 2 cm spatial resolution. The records cover the last ~60 kyrs. The stable carbon (δ13C; ‰ VPDB) and oxygen isotope (δ18O, ‰ VPDB) analyses were performed on a Thermo Scientific MAT 253 mass spectrometer with an automated Kiel IV Carbonate Preparation Device. The proxy data provide stratigraphical information and were used to calculate the ice volume-corrected δ18O of seawater (δ18Osw-ivc; ‰ VSMOW). The geochemical analyses were performed on a VARIAN 720–ES Axial ICP-OES, a simultaneous, axial-viewing inductively coupled plasma optical emission spectrometer coupled to a VARIAN SP3 sample preparation system at GEOMAR. Mg/Ca ratios (mmol/mol) were converted into thermocline (TT; °C) and sea surface temperatures (STT; °C). Contaminant phases are added: Al/Ca, Fe/Ca, Mn/Ca in mmol/mol).
