• Resumen

  • Preliminary results from multicores recovered in the Minorca sediment drift, south of the Western Mediterranean Deep Water formation area, reveal changes in deep-water circulation during the last 2500 yr. Records of grain-size and SST-Mg/Ca-derived from G. bulloides show oscillations in deep-water current intensities that could be related to cool periods on land, i.e. the Little Ice Age, but also denote some relationship with changes in sea surface salinity likely associated with changes in continental humid conditions.
