Abstract:
This dataset presents bottom water oxygen and temperature reconstructions from Subantarctic Atlantic sediment core MD07-3077 (44.15°S, 14.23°E; 3,770 m water depth) from MIS 12 to 10 (424-374 ka before present) based on Uvigerina spp. U/Ca, U/Mn and Mg/Ca ratios. The element/Ca ratios were measured on 11 to 20 specimens of Uvigerina spp. larger than 150 µm. Uvigerina spp. samples were crushed between glass plates and subsequently oxidatively cleaned according to established protocols (Barker et al., 2003). The analyses were completed via inductively coupled plasma-optical emission spectrometry (ICP-OES, Spectro Arcos; for Mg/Ca) and inductively coupled plasma-mass spectrometry (ICP-MS, Single Quadrupole Agilent 7900; for U/Ca, Mn/Ca) at the Institute of Geosciences at Kiel University (Kiel, Germany).
