    • Application of Clumped Isotope Thermometry to Benthic Foraminifera 

      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 (Peer reviewed; Journal article, 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 ...

    • InterCarb: A Community Effort to Improve Interlaboratory Standardization of the Carbonate Clumped Isotope Thermometer Using Carbonate Standards 

      Bernasconi, S.M.; Daeron, Mathieu; Bergmann, Kristin D.; Bonifacie, Magali; Meckler, Anna Nele; Affek, H. P.; Anderson, N.; Bajnai, D.; Barkan, E.; Beverly, E.; Blamart, D.; Burgener, L.; Calmels, D.; Chaduteau, C.; Clog, M.; Davidheiser-Kroll, B.; Davies, A.; Dux, F.; Eiler, J.; Elliott, B.; Fetrow, A. C.; Fiebig, J.; Goldberg, S.; Hermoso, M.; Huntington, K. W.; Hyland, E.; Ingalls, M.; Jaggi, M.; John, C. M.; Jost, A. B.; Katz, S.; Kelson, J.; Kluge, T.; Kocken, I. J.; Laskar, A.; Leutert, Thomas Jan; Liang, D.; Lucarelli, J.; Mackey, T. J.; Mangenot, X.; Meinicke, Niklas; Modestou, Sevasti Eleni; Müller, I. A.; Murray, S.; Neary, A.; Packard, N.; Passey, B. H.; Pelletier, E.; Petersen, S.; Piasecki, Alison; Ziegler, M. (Journal article; Peer reviewed, 2021)
      Increased use and improved methodology of carbonate clumped isotope thermometry has greatly enhanced our ability to interrogate a suite of Earth-system processes. However, interlaboratory discrepancies in quantifying ...

    • Mechanism of solid-state clumped isotope reordering in carbonate minerals from aragonite heating experiments 

      Chen, Sang; Ryb, Uri; Piasecki, Alison; Lloyd, Max; Baker, Michael B; Eiler, John M (Journal article; Peer reviewed, 2019-08-01)
      The clumped isotope compositions of carbonate minerals are subject to alteration at elevated temperatures. Understanding the mechanism of solid-state reordering in carbonate minerals is important in our interpretations of ...

    • 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 (Peer reviewed; Journal article, 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 ...
