Abstract:
This table includes temperatures calculated from carbonate clumped isotope measurements performed on middle Miocene ODP Site 761B benthic foraminifera.
A discrete binning method has been applied to the data presented here (as opposed to a probabilistic Gaussian window filter)
This data is an accompaniment to the manuscript "Warm middle Miocene Indian Ocean bottom water temperatures: comparison of clumped isotope and Mg/Ca records", Paleoceanography and Paleoclimatology, submitted.
