Séverine Martini


Chargée de recherche au CNRS à l'Institut Méditerranéen d'Océanologie (MIO, CNRS/AMU/IRD/UTLN), situé sur le campus de Luminy (Aix-Marseille Université) au sein de l'OSU PYTHEAS

Intérêts scientifiques :

  • Comprendre les rôles de la bioluminescence (bactérienne et eucaryotique) et son impact dans la pompe biologique du carbone.

  • Comprendre l’influence de la bioluminescence sur l’atténuation des flux de carbone particulaire

  • Décrire la diversité des organismes bioluminescents (de l'océan pélagique au milieu benthique), afin d'utiliser la mesure de cette capacité comme proxy des communautés du milieu obscur (des bactéries aux eucaryotes). 

  • Comprendre l'impact de la bioluminescence dans les réseaux trophiques mésopélagiques

Instrumentation :

  • Adapter et développer l'instrumentation nécessaire (et jusqu'alors inexistante en océanographie) au suivi des communautés et à leurs caractéristiques fonctionnelles (bioluminescence).

  • Techniques: Véhicules Opérés à Distance (ROVs), observatoires câblés, plongées en bouteilles (scientifique), échantillonnages Niskin, CTD, expérimentations en laboratoire​

  • Méthodes statistiques: Programmation (R-studio), analyse du signal, analyse de séries temporelles, modèles logistiques, analyses multivariées, statistiques, visualisation dynamique de données.
