Piasecki, Alison; Bernasconi, Stefano M.; Grauel, Anna-Lena; Hannisdal, Bjarte; Ho, Sze Ling; Leutert, Thomas Jan; Marchitto, Thomas M.; Meinicke, Niklas; Tisserand, Amandine Aline; Meckler, Anna Nele (Wiley, 2019-04)Obtaining absolute temperatures of the ocean in deep time is complicated by the lack of constraints on seawater chemistry. Seawater salinity, carbonate ion concentration, δ18O, and elemental abundance changes may obscure ...Journal article
Leutert, Thomas Jan (The University of Bergen, 2020-01-27)This PhD thesis focuses on the clumped isotope paleothermometer and its application to foraminiferal carbonates buried in ocean sediments. Based on new proxy evidence for ocean temperature, the thesis aims at improving our ...Doctoral thesis
Sensitivity of clumped isotope temperatures in fossil benthic and planktic foraminifera to diagenetic alteration Leutert, Thomas Jan; Sexton, Philip; Tripati, Aradhna; Piasecki, Alison; Ho, Sze Ling; Meckler, Anna Nele (Elsevier, 2019)Applying the clumped isotope (Δ47) thermometer to foraminifer microfossils offers the potential to significantly improve paleoclimate reconstructions, owing to its insensitivity to the isotopic composition of seawater ...Journal article
