Deglacial surface circulation changes in the northeastern Atlantic: Temperature and salinity records off NW Scotland on a century scale
Sea surface temperature and salinity estimates reconstructed from a core collected on the Barra Fan, northwest Scotland (56 degrees 43 ' N, 09 degrees 19 ' W; water depth 1320 m) deglacial period that are very similar to those observed in the delta(18)O records from Greenland ice cores. Th...
