Short summary
This study reports the hydrological variations recorded at different depths of the water column SW of the Faeroe Is. during the last glacial abrupt climatic events (Heinrich events and Dansgaard-Oeschger cycles). Our combined multiproxy and high-resolution approach allows us to evidence that 1) Greenland and Heinrich stadials were characterized by strong stratification of surface waters, 2) this surface stratification seems to have played a key role in the dynamics of the underlying water masses
This study reports the hydrological variations recorded at different depths of the water column...
