France, with its well-established infrastructure and leadership in Europe, is well positioned to establish this first atlas of marine genomes, which is as deep and rich as ever. The CEA and CNRS will lead this programme, supported by Ifremer, the MusĂ©um National d’Histoire Naturelle (MNHN), Aix-Marseille University (AMU), the UniversitĂ© Paris Sciences Lettres (PSL) and Sorbonne University (SU).
