• 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 ...
    • Lessons from a high-CO2 world: an ocean view from  ∼ 3 million years ago 

      McClymont, Erin L.; Ford, Heather; Ho, Sze Ling; Tindall, Julia C.; Haywood, Alan M.; Alonso-Garcia, Montserrat; Bailey, Ian; Berke, Melissa A.; Littler, Kate; Patterson, Molly O.; Petrick, Benjamin; Peterse, Francien; Ravelo, Ana Christina; Risebrobakken, Bjørg; De Schepper, Stijn; Swann, George E. A.; Kaustubh, Thirumalai; Tierney, Jessica E; Van der Weijst, Carolien; white, sarah; Abe-Ouchi, Ayako; Baatsen, Michiel L. J.; Brady, Esther C.; Chan, Wing-Le; Chandan, Deepak; Ran, Feng; Guo, Chenchen Guo; von der Heydt, Anna S.; Stephen, Hunter; Xiangyi, Li; Lohmann, Gerrit; Nisancioglu, Kerim Hestnes; Otto-Bliesner, Bette L.; Peltier, Richard W.; Stepanek, Christian; Zhang, Zhongshi (Journal article; Peer reviewed, 2020)
      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 ...
    • Limited exchange between the deep Pacific and Atlantic oceans during the warm mid-Pliocene and Marine Isotope Stage M2 “glaciation” 

      Braaten, Anna Hauge; Jakob, Kim A.; Ho, Sze Ling; Friedrich, Oliver; Galaasen, Eirik Vinje; De Schepper, Stijn; Wilson, Paul; Meckler, Anna Nele (Journal article; Peer reviewed, 2023)
      The Piacenzian stage (3.6–2.6 Ma) of the Pliocene is the most recent period where Earth experienced sustained intervals of global warmth analogous to predicted near-future climates. Despite considerable efforts to characterize ...
    • 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 ...
    • Stable Biological Production in the Eastern Equatorial Pacific Across the Plio-Pleistocene Transition (∼3.35–2.0 Ma) 

      Jakob, Kim A.; Ho, Sze Ling; Meckler, Anna Nele; Pross, Jörg; Fiebig, Jens; Keppler, Frank; Friedrich, Oliver (Journal article; Peer reviewed, 2021)
      Upwelling within the Eastern Equatorial Pacific (EEP) Ocean is a key factor for the Earth's climate because it supports >10% of the present-day biological production. The dynamics of upwelling in the EEP across the ...
