Marie-Emilie Clemence

  I completed my PhD in micropaleontology at the University of Paris (France). My work mainly focused on quantitative studies of ecology and evolution of both calcareous nannofossils and benthic foraminifers across past biotic crisis (e.g., Early Toarcian OAE, Triassic-Jurassic Boundary), as indicators of global/local marine perturbations of carbonate productivity, in synergy with chemical/isotopic and sedimentologic environmental proxies. My role in the project is to combines micropaleontological proxies to novel geochemical analyses to highlight key environmental changes in dissolved temperature and oxygen concentration, across the Mesozoic. High-resolution, local-scale analyses will be performed on samples collected during targeted fieldwork, such as stable O-isotopes of brachiopods and bulk samples and trace element (Mg/Ca ratios, U, V and Mo).
