| contents | In order to recognize the distribution of hydrothermal tracers south of the Azores, a series of cores has been sampled during the GEOFAR cruise. The distribution of the Mn concentrations shows that the hydrothermal influence is maximum within and to the north-west of the Lucky Strike segment. North of the East-Azores Fracture Zone the sediments are enriched in Ba which could be derived from different sources. The chemical composition of the interstitial water shows that water advection is limited. Mn, Cu, Ni fluxes evaluated in one site have increased during isotopic stages 4 and 2 and the deglaciation. |
