This study \r\npresents a unique 4500-year reconstruction of sea surface temperature \r\n(SST) obtained from alkenones in the North Atlantic Polar Front area \r\noff North Iceland, at an average temporal resolution of 4-5 years. \r\nSpectral analysis of this signal shows dominant multidecadal \r\noscillations which occurred with a stronger amplitude between 2500 \r\nand 4200 years BP, hand in hand with fluctuations of bottom currents \r\nindicated by paleomagnetic proxies. Contemporaneous large excursions \r\nof the Inter-tropical Convergence Zone (ITCZ) are also recorded by \r\nthe distant Cariaco titanium time series, suggesting a link with \r\nlow latitude Atlantic climate. We speculate that the oscillations \r\nreflect changes of the Meridional Overturning Circulation (MOC) \r\ninduced by increased ENSO activity.","author":null,"citation":"Sicre, M.-A., P. Yiou, J.
