Atlantic gyres variability during the last millennium
International audience We investigate the low frequency variability of the Atlantic subpolar and subtropical gyres over the last millennium. First, a compilation of the several recent proxy reconstructions (e.g. Sicre et al. 2008, Richter et al. 2009 for the subpolar gyre, Mc Gregor et al. 2007 and...
