• 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 ...

      A range of future climate scenarios are projected for high atmospheric CO2 concentrations, given uncertainties over future human actions as well as potential environmental and climatic feedbacks. The geological record ...
    • 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 ...
