Abstract:
This table includes temperatures calculated from carbonate clumped isotope measurements performed on middle Miocene benthic foraminifera from Ocean Drilling Program (ODP) Hole 120-747A, Kerguelen Plateau, and is an accompaniment to the manuscript "Southern Ocean bottom water cooling and ice sheet expansion during the middle Miocene climate transition", Climate of the Past, submitted. A complete set of individual measurement data, including sample labels, depth and raw mass spectrometer data, can be found on the EarthChem database (doi to be added when available).
