Hydrological relationship between the North Atlantic Ocean and the Mediterranean Sea during the past 15-75 kyr
International audience The Mediterranean Sea hydrology at the time of the Heinrich formation in the North Atlantic Ocean was analyzed by comparing sea surface temperatures (SSTs) and oxygen isotope composition of seawater (δw) changes during the past 75 kyr in two marine cores. These were compared t...
