    • 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 (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 ...

    • Causality from palaeontological time series 

      Hannisdal, Bjarte; Liow, Lee Hsiang (Wiley, 2018-07)
      As custodians of deep time, palaeontologists have an obligation to seek the causes and consequences of long‐term evolutionary trajectories and the processes of ecosystem assembly and collapse. Building explicit process ...

    • Disentangling rock record bias and common-cause from redundancy in the British fossil record 

      Dunhill, Alexander M.; Hannisdal, Bjarte; Benton, Michael J. (Nature Publishing Group, 2014-09-04)
      The fossil record documents the history of life, but the reliability of that record has often been questioned. Spatiotemporal variability in sedimentary rock volume, sampling and research effort especially frustrates ...

    • Transfer entropy computation using the Perron-Frobenius operator 

      Diego, David; Haaga, Kristian Agasøster; Hannisdal, Bjarte (APS, 2019)
      We propose a method for computing the transfer entropy between time series using Ulam's approximation of the Perron-Frobenius (transfer) operator associated with the map generating the dynamics. Our method differs from ...
