Une application fr\u00e9quemment utilis\u00e9e dans le domaine de la pal\u00e9oc\u00e9anographie est bas\u00e9 sur le rapport Mg\/Ca en tant que thermom\u00e8tre (Barker al. 2005). Le Mg\/Ca ainsi que d\u2019autres rapports (Sr\/Ca, U\/Ca) mesur\u00e9s dans les coraux peuvent aussi servir de pal\u00e9othermom\u00e8tre (Cardinal et al. 2001, Silenzi et al. 2005). Le rapport Mg\/Ca des foraminif\u00e8res a \u00e9t\u00e9 appliqu\u00e9 \u00e0 de nombreuses archives du Quaternaire r\u00e9cent, ce qui a nous permis d\u2019\u00e9valuer l\u2019influence du for\u00e7age radiatif en relation avec la concentration en CO2 atmosph\u00e9rique sur la temp\u00e9rature de l\u2019eau en surface dans l\u2019oc\u00e9an Pacifique tropical ouest (Tachikawa et al. 2014) et de reconstituer la structure thermique verticale dans la colonne d\u2019eau par la combinaison de plusieurs esp\u00e8ces de foraminif\u00e8res calcifiants \u00e0 profondeurs diff\u00e9rentes (Regoli et al. 2015, Hollstein et al. 2018). L\u2019application du rapport Mg\/Ca n\u2019est pas limit\u00e9e au Quaternaire r\u00e9cent. Le proxy nous a permis de tracer la circulation de surface de l\u2019Atlantique Nord durant l\u2019intensification de la glaciation de l\u2019h\u00e9misph\u00e8re Nord au Plio-Pl\u00e9istoc\u00e8ne (Bolton et al. 2018).
