2021-05-13: Results from an in-progress study An experimental constraint on the oxygen isotope fractionation (18O/16O) between water and aqueous hydroxide ion will be presented at the Goldschmidt online conference on 7 July 2021. Read the abstract here.
2021-04-13: New article published in Geochemistry, Geophysics, Geosystems: InterCarb: A community effort to improve inter‐laboratory standardization of the carbonate clumped isotope thermometer using carbonate standards. This community effort, led by Stefano Bernasconi and involving 22 laboratories, provides consensus ∆47 values for carbonate standards and describes best practices for carbonate-based standardisation.

2020-12-31: New article published in Földtani Közlöny (in Hungarian): Modern methods of cyclostratigraphy and astrochronology and their applications. Cyclostratigraphy, the science of reading the stratigraphic record of Milankovitch cycles, i.e., climate cycles driven by periodic changes in Earth’s orbital parameters, both provides a means to measure geological time and to reconstruct palaeoclimate. Here, we review the physical drivers of cyclical changes in geological time series, introduce the steps of spectral analyses, and discuss case studies.

2020-08-10: New article published in Nature Communications: Dual clumped isotope thermometry resolves kinetic biases in carbonate formation temperatures. Palaeotemperature reconstructions suffer from inaccuracies related to kinetic fractionations occurring during carbonate mineral growth. Here we show that dual clumped isotope thermometry can identify the origin of these kinetic biases and allows the reconstruction of accurate environmental temperatures.
