These data correspond to the analysis results for samples collected by the French submersible "Nautile" during the Parisub cruise (2010, R/V L'Atalante, Ifremer). The samples come from a profile transverse to the EPR axis (15.6°N), where the ridge seems to be coupled to prominent seamounts located nearby. These data aim at determining at high resolution the isotopic variability of the basalts recorded over the past 300 ky of accretion in order to provide a chronological reading of source composition and ridge-seamounts interaction.
