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).
