The 4.2 ka event in the Euro-Mediterranean region -A study from the MISTRALS/PALEOMEX program
Abstract : High-resolution records documenting the 4.2 ka event (from 4200 to 3900 cal yr BP) are scarce. Archaeological and paleoenvironmental data from continental archives suggest that this event is coincident with a megadrought in the eastern Mediterranean basin. Here, we present an unprecedented high-resolution alkenone-based sea surface temperature (SST) record from the northwestern Mediterranean Sea showing a stepwise cooling of ca. 2°C between 4400 and 3800 yr BP, which shares similarities with speleothem records from central Europe and the Mediterranean region. Our data suggest a reorganization of the North Atlantic atmospheric circulation during this event.
